  • 00:00:01
    hey guys and welcome to petroped now
  • 00:00:05
    look in the comments section of any of
  • 00:00:07
    my electric car reviews and there's a
  • 00:00:09
    common theme you will see comments in
  • 00:00:11
    there a lot about batteries things like
  • 00:00:13
    ah but the batteries will be dead in two
  • 00:00:16
    or three years the efficiency is going
  • 00:00:18
    to die just like my smartphone or you
  • 00:00:20
    shouldn't charge an electric car up to
  • 00:00:22
    100 or you shouldn't use fast charging
  • 00:00:25
    it deteriorates the battery oh what
  • 00:00:27
    about the long-term cost of electric
  • 00:00:29
    motor maintenance how much is it going
  • 00:00:31
    to cost to change out my battery pack
  • 00:00:34
    every single video has comments like
  • 00:00:36
    this so I wanted to bust some of those
  • 00:00:39
    myths because there's a lot of
  • 00:00:40
    misinformation out there a lot of
  • 00:00:42
    misunderstanding so I've come all the
  • 00:00:44
    way to Newtown in Wales back to Electric
  • 00:00:47
    classic cars I haven't been here since
  • 00:00:49
    we finished filming season two of
  • 00:00:52
    vintage voltage so come back to see my
  • 00:00:54
    old mate moggy and the team electric
  • 00:00:56
    classic cars it's great to meet up with
  • 00:00:58
    everybody but of all the people I know
  • 00:01:00
    moggy's the guy that can answer those
  • 00:01:02
    questions moggy is the guy that can bust
  • 00:01:04
    those myths so let's head on inside out
  • 00:01:07
    of this horrible wet weather and see if
  • 00:01:09
    we can do a bit of myth busting shall we
  • 00:01:15
    [Music]
  • 00:01:21
    thank you
  • 00:01:24
    nice it's good to be back good to see
  • 00:01:27
    you again right now we were working out
  • 00:01:29
    Orient it's been a good 18 months since
  • 00:01:31
    I've been here don't ask me right I
  • 00:01:32
    don't even remember what I had for
  • 00:01:34
    breakfast let alone a lot has happened
  • 00:01:36
    since we finished filming Series 2 of
  • 00:01:38
    vintage voltage you guys go from
  • 00:01:40
    strength to strength well we keep
  • 00:01:42
    ourselves you've got some epic cars in
  • 00:01:45
    here
  • 00:01:46
    um cool cars most epic of them all being
  • 00:01:49
    your funk up that is ridiculous oh yeah
  • 00:01:51
    uh we still haven't named that yet death
  • 00:01:53
    trap I want to name it but the family
  • 00:01:55
    doesn't want to leave it Dev trap the
  • 00:01:57
    coffin well yeah well a thousand kilos
  • 00:02:01
    thousand horsepower four-wheel drive
  • 00:02:03
    four-wheel drive
  • 00:02:04
    1150 newton meters yeah you're mental I
  • 00:02:08
    saw you trying to squeeze yourself into
  • 00:02:10
    it down at Goodwood mate so a lot of
  • 00:02:12
    people have tried to squeeze themselves
  • 00:02:14
    into it they've got race licenses
  • 00:02:16
    hello it's uh anybody over five foot 11
  • 00:02:21
    people struggle in it and that's by
  • 00:02:23
    Design
  • 00:02:25
    now I've traveled all this way because I
  • 00:02:28
    need your help go ahead I am fed up
  • 00:02:31
    whenever I review an electric car
  • 00:02:34
    comments about batteries stop reviewing
  • 00:02:37
    electric cars well you know you've got
  • 00:02:40
    to keep a balance and and a lot of the
  • 00:02:42
    comments are I just want to kind of try
  • 00:02:44
    and bust some myths oh yeah you must get
  • 00:02:46
    the same thing on your channel before we
  • 00:02:49
    can get going I'll put links to Electric
  • 00:02:51
    classic cars YouTube channel and all the
  • 00:02:52
    socials make sure you give them a follow
  • 00:02:53
    if you want to know more about what
  • 00:02:54
    they're doing in here you don't need to
  • 00:02:56
    watch vintage voltage anymore you just
  • 00:02:57
    tune into your YouTube channel yeah so
  • 00:03:02
    let's bust some myths go on it and I've
  • 00:03:04
    got I've got a list of things because
  • 00:03:05
    this this guy is the guy I know who
  • 00:03:08
    knows more about this stuff than anybody
  • 00:03:10
    oh you're lining me up for a fall now I
  • 00:03:11
    know I know and we're right so let's do
  • 00:03:13
    batteries we have this is where you
  • 00:03:15
    assemble your battery packs yeah this is
  • 00:03:18
    actually quite privileged to be allowed
  • 00:03:19
    in here well we're not allowed to touch
  • 00:03:21
    anything well you say because all the
  • 00:03:23
    terminals are uh covered yeah and this
  • 00:03:25
    hasn't actually Gone live proper yet so
  • 00:03:27
    uh you're safe but don't touch anything
  • 00:03:29
    you can hurt yourself with this well
  • 00:03:31
    this is a uh rear pack out of the
  • 00:03:34
    Porsche 912 which is also 911 pack as
  • 00:03:37
    well but without 912 over there this is
  • 00:03:39
    the rear pack out that that's 27 odd
  • 00:03:42
    kilowatt hours just in the rear wow and
  • 00:03:44
    there's another one exactly the same
  • 00:03:45
    goes in the front quite dinky it's quite
  • 00:03:47
    dinky yeah so here's the thing so first
  • 00:03:50
    question then go on in I buy a new
  • 00:03:52
    electric car is there a prize if you're
  • 00:03:55
    getting more right yeah definitely
  • 00:03:56
    definitely first question for ten so buy
  • 00:03:59
    a new electric car and the battery
  • 00:04:01
    starts to lose
  • 00:04:03
    um its efficiency it's effective it's a
  • 00:04:06
    bit like your smartphone so after two
  • 00:04:07
    years the battery is not going to be
  • 00:04:09
    able to hold as much charge your range
  • 00:04:10
    will decrease and after three or four
  • 00:04:12
    years the battery is going to be
  • 00:04:13
    knackered and you'll have to buy a new
  • 00:04:15
    one and they cost lots of money okay so
  • 00:04:17
    that is what's called battery
  • 00:04:19
    degradation yep and uh yeah you're
  • 00:04:22
    correct batteries
  • 00:04:24
    um degrade if you like over their
  • 00:04:27
    lifetime and their use if you like and
  • 00:04:29
    the charge cycles and charge cycles yeah
  • 00:04:31
    so that's what I mean by use yeah um but
  • 00:04:33
    it's nowhere near as bad as you know
  • 00:04:36
    media makes out bear in mind Media news
  • 00:04:39
    now is driven by clicks and Views not
  • 00:04:41
    facts really it's a shocker I know but
  • 00:04:44
    literally if there's a bad news story
  • 00:04:46
    about something they'll push it and then
  • 00:04:48
    they'll get views from it and on it goes
  • 00:04:50
    and goes viral happy new story about
  • 00:04:52
    batteries hardly ever gets any views so
  • 00:04:55
    that's the first thing to um understand
  • 00:04:57
    is you know news and media Works off
  • 00:04:59
    sensationalist stuff now ticks and Views
  • 00:05:01
    not facts okay but coming back to uh
  • 00:05:04
    battery degradation so what happens is
  • 00:05:06
    over the lifetime of a battery the the
  • 00:05:08
    ceiling if you like comes down so as you
  • 00:05:12
    charge it and use it and charge it and
  • 00:05:13
    use it it doesn't quite get to 100 as it
  • 00:05:16
    used to do years ago but when I say it's
  • 00:05:19
    not as bad as people make out it and
  • 00:05:22
    people can you know Google this as well
  • 00:05:24
    if they like go out and Google Tesla
  • 00:05:27
    battery degradation for instance and
  • 00:05:29
    you'll find that after around about 200
  • 00:05:32
    000 miles you'll be down to around about
  • 00:05:34
    90 percent of the original battery
  • 00:05:36
    capacity that you had when you started
  • 00:05:39
    200 000 miles yes which is more many
  • 00:05:43
    people do 200 000 miles in their car I
  • 00:05:46
    know that that is more than the average
  • 00:05:48
    lifetime of most um internal combustion
  • 00:05:50
    engine cars absolutely I think that's
  • 00:05:52
    around about 180 but I think the most
  • 00:05:55
    I've ever done on a car I did like 100
  • 00:05:57
    000 miles in a in a petrol Commons but
  • 00:05:59
    bear in mind
  • 00:06:00
    the electric car is still working yeah
  • 00:06:02
    all you've got now is a range that is 90
  • 00:06:04
    of what you had when you started yeah
  • 00:06:07
    now there are outliers there some that
  • 00:06:10
    will be better than that some that'd be
  • 00:06:11
    worse than that but I think where the
  • 00:06:13
    some of the bad stories have happened
  • 00:06:15
    bear in mind you know news items or pick
  • 00:06:18
    the worst case scenario and then push
  • 00:06:19
    that but the older generation cars that
  • 00:06:22
    didn't have
  • 00:06:24
    um thermal Management on their batteries
  • 00:06:26
    and I'll come to that in a minute the
  • 00:06:27
    older generation electric cars like
  • 00:06:29
    first generation Nissan leafsarena Zoe's
  • 00:06:31
    their battery degradation was worse yeah
  • 00:06:34
    because they weren't keeping their
  • 00:06:36
    battery temperatures in the happy
  • 00:06:38
    Goldilocks zone yeah so what is thermal
  • 00:06:41
    management well that is good question
  • 00:06:42
    that's our next question is coming back
  • 00:06:44
    to you when you mentioned about your
  • 00:06:46
    iPhone battery for instance that yes
  • 00:06:49
    this is knackered after like 18 months
  • 00:06:50
    correct and did you know why because it
  • 00:06:52
    gets hot because it gets hot now
  • 00:06:55
    batteries like like humans like to be in
  • 00:06:58
    a certain temperature zone anything
  • 00:07:00
    between say you know zero and 50 degrees
  • 00:07:04
    they're okay but really they're more
  • 00:07:06
    happy around about the 20 degree Zone
  • 00:07:08
    yeah okay so if we're warm and nice and
  • 00:07:11
    comfortable batteries are too so that's
  • 00:07:13
    what thermal management does is keeping
  • 00:07:15
    the batteries within its happy Zone yeah
  • 00:07:18
    and if you haven't got thermal
  • 00:07:19
    Management in your batteries heating the
  • 00:07:21
    batteries up above zero degrees or
  • 00:07:23
    keeping it below say 40 degrees or
  • 00:07:25
    whatever then the batteries degrade
  • 00:07:28
    quicker okay and that's why the early
  • 00:07:31
    generation Nissan leaves and things like
  • 00:07:32
    that which didn't have thermal
  • 00:07:34
    management degrade quicker in their
  • 00:07:36
    battery life you know die quick if you
  • 00:07:38
    like and that's why it comes a surprise
  • 00:07:40
    to many people that electric cars have
  • 00:07:42
    radiators
  • 00:07:44
    yes the kind of yep yep for cooling and
  • 00:07:47
    yeah so the reason why I was hesitant
  • 00:07:49
    there's the radiator is not just for the
  • 00:07:50
    batteries no that's also cooling down
  • 00:07:52
    the motor and inverter yep so the motor
  • 00:07:55
    and inverter and electric car is very
  • 00:07:57
    efficient
  • 00:07:58
    and when you're talking about
  • 00:07:59
    inefficiencies for instance like a
  • 00:08:01
    petrol car is around about say 20 to 30
  • 00:08:04
    efficient that means that of the energy
  • 00:08:06
    that you put in 80 to 70 of that energy
  • 00:08:09
    that you put in is lost to heat
  • 00:08:13
    um through the radiator exhaust noise
  • 00:08:15
    Etc et cetera so there's a lot of energy
  • 00:08:17
    that's turned into heat in a petrol car
  • 00:08:19
    that's why you need to radiate it but
  • 00:08:21
    even with a electric motor which is 90
  • 00:08:24
    to 96 efficient that still means at ten
  • 00:08:27
    to four percent of your energy putting
  • 00:08:29
    in is turned into heat so you need a
  • 00:08:30
    radiator to just keep that cool but it's
  • 00:08:33
    like lukewarm yeah rather than boiling
  • 00:08:36
    and scrolling hot but you still need a
  • 00:08:38
    radiator for
  • 00:08:40
    um batteries to keep them cool but you
  • 00:08:43
    also need to heat them up in the winter
  • 00:08:45
    time just to get them up to their most
  • 00:08:47
    efficient if you like
  • 00:08:49
    um now a lot of modern electric cars and
  • 00:08:51
    anybody that's considering an electric
  • 00:08:52
    car out there I thoroughly recommend you
  • 00:08:54
    try to get one that's got a heat pump in
  • 00:08:56
    yeah because as We Know heat pumps are
  • 00:08:59
    even more efficient at you know taking
  • 00:09:01
    energy and turning it into either heat
  • 00:09:03
    or cooling for instance and that means
  • 00:09:06
    that
  • 00:09:07
    um they're taking less energy out of the
  • 00:09:09
    battery pack to be able to keep that
  • 00:09:11
    temperature of the battery pack in its
  • 00:09:12
    Goldilocks zone so
  • 00:09:14
    top tip to anybody considering AVS just
  • 00:09:17
    ask the sales guy has this got a heat
  • 00:09:19
    pump in yeah
  • 00:09:20
    then that's a good thing so summarize
  • 00:09:24
    then you're not saying these have an
  • 00:09:25
    infinite life nope they are going to
  • 00:09:28
    degrade over time their their efficiency
  • 00:09:29
    is going to go down oh it's interesting
  • 00:09:31
    I was saying to you off camera the I had
  • 00:09:33
    a Lexus EV and they they kind of say
  • 00:09:35
    after 10 years it's still going to be
  • 00:09:37
    around about 90 of its
  • 00:09:41
    um so so it's it's not it's not like I
  • 00:09:45
    know they're in a similar technology to
  • 00:09:47
    what you find in an iPhone or a
  • 00:09:49
    smartphone the lithium-based yeah but
  • 00:09:51
    don't think of it all that's just like a
  • 00:09:53
    big iPhone battery because it's really
  • 00:09:54
    not and another thing that people get
  • 00:09:56
    mixed up with is Nica batteries are the
  • 00:09:58
    90s yeah when you have those cordless
  • 00:10:00
    drills and after a year they're like oh
  • 00:10:02
    my God it's died in five minutes nicad
  • 00:10:04
    is not the same as lithium-based
  • 00:10:06
    batteries and the other interesting
  • 00:10:08
    thing that's happening now is we're
  • 00:10:09
    seeing more lfp batteries coming in
  • 00:10:12
    which lfp stands for lithium ion not ion
  • 00:10:15
    as in iom lithium iron phosphate and
  • 00:10:19
    those batteries are more stable and
  • 00:10:22
    they're they last longer so lfp
  • 00:10:24
    batteries are even better so the
  • 00:10:26
    technology is always improving yeah and
  • 00:10:28
    as I say lfp batteries or cars with lfp
  • 00:10:31
    batteries another step forward in my
  • 00:10:33
    mind now in terms of when you come to
  • 00:10:35
    replace one of these they aren't cheap
  • 00:10:37
    things nope
  • 00:10:39
    so I mean what kind of you know for a um
  • 00:10:42
    I guess it depends on the size of the
  • 00:10:44
    battery pack in a kind of first place
  • 00:10:46
    yeah if you're buying it from a
  • 00:10:47
    manufacturer it's a big amount of money
  • 00:10:49
    but that's not something that the
  • 00:10:51
    average person who buys electric cars
  • 00:10:53
    gonna have to worry about for quite a
  • 00:10:54
    while yeah and this is
  • 00:10:56
    um uh something that runs into
  • 00:11:00
    um warranty periods yeah so electric
  • 00:11:02
    cars have quite a long warranty period
  • 00:11:04
    why because there's nothing really that
  • 00:11:07
    goes wrong on the motors really you know
  • 00:11:09
    compared to all the thousands of moving
  • 00:11:11
    parts and the petrol and diesel car for
  • 00:11:12
    instance so they know they can warranty
  • 00:11:14
    that drivetrain to the you know to the
  • 00:11:17
    nth degree and the battery packs are
  • 00:11:19
    actually lasting a lot longer than
  • 00:11:20
    people initially thought back like 10
  • 00:11:23
    years ago for instance or even seven
  • 00:11:24
    years ago it lasted a lot longer so
  • 00:11:26
    you're getting eight year warranty
  • 00:11:28
    periods and things like that which is
  • 00:11:29
    you know you wouldn't normally see that
  • 00:11:31
    in you know petrol and Diesel land
  • 00:11:35
    um but yeah after I don't know 300 000
  • 00:11:38
    whatever miles at some point you're
  • 00:11:41
    going to say hang on my battery is now
  • 00:11:43
    at you know 60 70 what it used to be and
  • 00:11:46
    if you're doing local drives that might
  • 00:11:48
    still be okay but at some point you
  • 00:11:50
    might say you know what this battery has
  • 00:11:53
    had it I'm going to replace it and at
  • 00:11:55
    that point then yes there's going to be
  • 00:11:57
    a big chunk of change you're going to be
  • 00:11:58
    forking out to change your battery why
  • 00:12:01
    because it's the main part of the car
  • 00:12:03
    yeah that's your main ticket it's like
  • 00:12:05
    replacing a roof on your on your house
  • 00:12:07
    yeah yeah at some point you're going to
  • 00:12:09
    probably have to replace the roof and
  • 00:12:10
    it's going to be very expensive but it's
  • 00:12:12
    going to be a long way out yeah yeah
  • 00:12:13
    yeah but refouching your cottage there
  • 00:12:15
    you go yeah exactly you haven't got a
  • 00:12:17
    thatched
  • 00:12:19
    so yeah there is a big chunk of change
  • 00:12:21
    that you'll need way into the distance
  • 00:12:24
    yeah um to replace that battery pack
  • 00:12:27
    um and you can either replace it with a
  • 00:12:29
    good second hand one for instance if
  • 00:12:31
    your your old car engine won't pop yeah
  • 00:12:34
    would you go to Jaguar and get a brand
  • 00:12:37
    spanking new Jaguar engine to put in it
  • 00:12:40
    yeah probably not yeah you probably go
  • 00:12:42
    to a specialist that does reconditioned
  • 00:12:44
    engines or maybe even buy a second hand
  • 00:12:47
    engine off eBay yeah you do the same
  • 00:12:48
    with electric so you don't need to go
  • 00:12:50
    back to you know Jaguar to buy a brand
  • 00:12:53
    spanking new battery pack to put in your
  • 00:12:55
    i-pace yeah so cool okay that's actually
  • 00:12:58
    one more thing on that interestingly
  • 00:13:00
    enough I had a conversation with a
  • 00:13:01
    company that um when we get bad
  • 00:13:04
    batteries in because we you know we
  • 00:13:05
    repurpose some batteries like Tesla
  • 00:13:07
    batteries for instance
  • 00:13:09
    um and VW ID yeah four batteries just in
  • 00:13:12
    that pack there and you know sometimes
  • 00:13:14
    you get them in and through quality
  • 00:13:16
    assurance tests that we do some are not
  • 00:13:19
    usable so then you have to you get rid
  • 00:13:21
    of them so we have a company where we
  • 00:13:24
    send the batteries to that recycle
  • 00:13:25
    batteries another interesting
  • 00:13:27
    conversation with a guy um a couple of
  • 00:13:28
    weeks ago and said how's it going
  • 00:13:31
    not brilliant he said and you know why
  • 00:13:34
    because they can't get any batteries
  • 00:13:36
    they've got nothing to recycle that's
  • 00:13:39
    how good batteries are you've seen it's
  • 00:13:40
    like you know the downside of batteries
  • 00:13:42
    being you know so good and Lasting so
  • 00:13:44
    long is the fact that they're struggling
  • 00:13:46
    to get second-hand batteries so yeah
  • 00:13:49
    just a side note there that yes
  • 00:13:51
    batteries can be recycled by the way
  • 00:13:52
    yeah if anybody is going oh they can't
  • 00:13:54
    be recycled oh yes they can yeah and
  • 00:13:56
    there's companies out there screaming
  • 00:13:57
    for them but yeah just an interesting
  • 00:13:59
    conversation I had with that company uh
  • 00:14:01
    last week so okay so then let's talk
  • 00:14:04
    about how we kind of maybe help with the
  • 00:14:06
    health of the battery in terms of best
  • 00:14:08
    practice for charging because the next
  • 00:14:10
    comment I get
  • 00:14:12
    um is
  • 00:14:13
    um oh if you if you use Rapid charges
  • 00:14:16
    yeah it's a rapid DC charging that
  • 00:14:18
    that's damaging to the battery you
  • 00:14:20
    should never charge a battery up to 100
  • 00:14:22
    that's damaging to the battery damaging
  • 00:14:25
    is uh too aggressive word to use yeah
  • 00:14:28
    okay
  • 00:14:29
    um if you want you know bearing mind a
  • 00:14:32
    manufacturer wouldn't allow you to do
  • 00:14:33
    something that will damage the battery
  • 00:14:34
    no okay so you know the battery
  • 00:14:37
    Management systems on these battery
  • 00:14:38
    packs will prevent you from damaging a
  • 00:14:41
    battery yeah but there are ways the same
  • 00:14:44
    um you know if you wanted to elongate
  • 00:14:46
    the life cycle of an engine Don't
  • 00:14:48
    redline it every time you change gear
  • 00:14:50
    yeah it's things like that basically
  • 00:14:52
    yeah so redlining it every time you
  • 00:14:54
    change gear it's probably going to bring
  • 00:14:55
    that life cycle out of your engine down
  • 00:14:57
    again with a battery pack Don't redline
  • 00:14:59
    it all the way to full every time you're
  • 00:15:01
    charging it up because it'll bring the
  • 00:15:03
    life cycle of that battery pack down so
  • 00:15:06
    the usual thing that people say is keep
  • 00:15:09
    it within the 20 80 range
  • 00:15:12
    you know if you keep it within the 20 to
  • 00:15:15
    80 range you will elongate the lifetime
  • 00:15:19
    of that battery as much as it can be
  • 00:15:21
    yeah and supercharging you know the
  • 00:15:23
    reason why supercharging
  • 00:15:25
    um can you know bring the lifetime of a
  • 00:15:27
    battery down and and it's not like oh
  • 00:15:29
    you're gonna have a lifetime no you're
  • 00:15:30
    not yeah you'll just bring it down again
  • 00:15:32
    the redlining an engine every time you
  • 00:15:34
    change gear is a good example yeah
  • 00:15:37
    um so that's what you did when you were
  • 00:15:40
    yeah
  • 00:15:42
    but at least I could rebuild my race
  • 00:15:44
    engine yeah
  • 00:15:46
    um but with supercharging what you're
  • 00:15:48
    doing is you are putting a load of amps
  • 00:15:50
    in really quickly and therefore you're
  • 00:15:52
    stressing the battery out yeah not huge
  • 00:15:54
    amount but stressing the battery out
  • 00:15:55
    within its happy parameters but the
  • 00:15:57
    temperature's going up yeah and anytime
  • 00:16:00
    you get heat Cycles in anything in life
  • 00:16:01
    engines Etc anytime you get heat cycles
  • 00:16:04
    and stuff you're also you know reducing
  • 00:16:07
    the the life cycle of that battery so if
  • 00:16:09
    you really want to
  • 00:16:11
    um you know get yeah many miles out of a
  • 00:16:13
    battery pack charged up at home on a
  • 00:16:16
    seven kilowatt charger keep it within 20
  • 00:16:18
    and 80 and you'll find that your you
  • 00:16:21
    know lifetime of that battery is way
  • 00:16:24
    longer than you'd expect and most most
  • 00:16:27
    home charges and or cars have the
  • 00:16:30
    ability to set criteria as to what
  • 00:16:32
    percentage you're going to charge the
  • 00:16:33
    car oh yeah so you just you don't it's
  • 00:16:35
    not like you have to guess and run out
  • 00:16:36
    and unplug it at 80 you just tell the
  • 00:16:38
    car don't charge Beyond 80 most cars
  • 00:16:40
    have that feature as well and also a lot
  • 00:16:42
    of smart Chargers yeah you know I I
  • 00:16:45
    charge up into today good yeah yeah so I
  • 00:16:47
    mean my home my home charger is an Omi
  • 00:16:50
    Air charger and in that I can set it to
  • 00:16:53
    only charge up
  • 00:16:54
    um at night time on a cheap tariff so
  • 00:16:56
    I'm charging up now last year it's five
  • 00:16:58
    pence per kilowatt hour which is
  • 00:17:00
    insanely cheap yeah and now I think it's
  • 00:17:01
    gone up to an insanely massive 7.5 Pence
  • 00:17:05
    per kilowatt hour so I'm charging up my
  • 00:17:07
    car 7.5 Pence per kilowatt hour yeah and
  • 00:17:11
    also in my power wall and my house has
  • 00:17:13
    driven off batteries so all my house and
  • 00:17:16
    cars charged up you know between that
  • 00:17:18
    time which my electricity graph if you
  • 00:17:21
    like is hilarious because there's
  • 00:17:23
    there's nothing nothing and at midnight
  • 00:17:24
    it goes
  • 00:17:26
    at 4 30 in the morning goes do nothing
  • 00:17:28
    and then it's off yeah it's the weirdest
  • 00:17:31
    like graph you'll ever see so let's do
  • 00:17:34
    the the 20 to 80 thing as well so when
  • 00:17:36
    you're on a journey
  • 00:17:38
    I wanted to not bust a myth but explain
  • 00:17:41
    and I've explained this on videos before
  • 00:17:43
    but you do it way better than I do that
  • 00:17:45
    first 20 and the last 20 of the charge
  • 00:17:48
    takes longer than the middle 60 correct
  • 00:17:52
    yeah explain why and what the position
  • 00:17:54
    when I'm driving home tonight
  • 00:17:56
    yeah the quickest way for me to get home
  • 00:17:59
    if I need to charge is to just charge 20
  • 00:18:01
    to 80 get on my way then get to the next
  • 00:18:04
    20 to 80 get on my rather than sitting
  • 00:18:06
    there till I get to 100 so so the best
  • 00:18:09
    way to describe it right so imagine a
  • 00:18:11
    barrel of water that you've got to fill
  • 00:18:13
    up yeah okay now as it gets to the top
  • 00:18:16
    okay and you've got like a a fireman
  • 00:18:19
    hose to fill it up yeah okay but you're
  • 00:18:21
    not allowed to spill any water over the
  • 00:18:23
    top when it gets to full so you'll start
  • 00:18:25
    off with like loads of Like Water full
  • 00:18:28
    thing and then as it gets to about 80
  • 00:18:29
    you're getting up to the top now bear in
  • 00:18:31
    mind you're not allowed to spill it
  • 00:18:32
    which means in voltage world you don't
  • 00:18:34
    want it to go over a certain voltage
  • 00:18:36
    yeah in the cells so you'll say oh hang
  • 00:18:39
    on turn it down turn it down a bit we're
  • 00:18:40
    getting to the top turn it down oh again
  • 00:18:42
    really stop now turn it down a bit more
  • 00:18:43
    turn it there so that means that up to
  • 00:18:46
    80 it's really quick and an 80 to 100 it
  • 00:18:49
    starts to get slower slower slower
  • 00:18:51
    slower so when you're supercharging
  • 00:18:52
    don't sit there thinking oh I'm gonna
  • 00:18:54
    wait till it's 100 because it'll get a
  • 00:18:56
    80 really quickly and then it will start
  • 00:18:58
    to slow down once you get to 80 85 get
  • 00:19:01
    on the way again yeah
  • 00:19:03
    let's go you only want to get to 100 the
  • 00:19:05
    night before
  • 00:19:07
    when you're just about to do a long
  • 00:19:08
    journey the next day stick it on the
  • 00:19:10
    home charger set to 100 and by the time
  • 00:19:12
    you wake up it'll be good to go but
  • 00:19:13
    never get it to 100 on the way up
  • 00:19:15
    yesterday I sat on a DC charger and went
  • 00:19:18
    to 100 one because it only took less
  • 00:19:20
    than an hour and that's how long I took
  • 00:19:22
    add me food and also I knew I was coming
  • 00:19:24
    here and we might want to I wasn't gonna
  • 00:19:25
    be able to charge last night so there
  • 00:19:27
    were reasons why I went to 100 so
  • 00:19:28
    otherwise yeah
  • 00:19:31
    and you know people say don't go do it
  • 00:19:33
    don't go to zero percent which again you
  • 00:19:36
    know just for the reasons I've already
  • 00:19:38
    explained it's never a good idea to go
  • 00:19:40
    down to zero percent but you can no
  • 00:19:43
    problem at all right well I've done it
  • 00:19:44
    many times I've gone below zero percent
  • 00:19:46
    say a lot of cars I did a thing with
  • 00:19:48
    Toyota uh earlier this year and there
  • 00:19:51
    when it says zero it's still got ten
  • 00:19:54
    percent just like fuel gauge still a
  • 00:19:56
    bunch of bunch of stuff in there when we
  • 00:19:58
    were in college all those years ago
  • 00:19:59
    right yeah mate when it really could
  • 00:20:01
    fill your car up for 10 quid oh God yeah
  • 00:20:03
    I used to fill my car up um yeah for
  • 00:20:05
    literally about 10 quid and drive all
  • 00:20:06
    the way to Wales yeah you know on 10
  • 00:20:09
    quid it's insane
  • 00:20:10
    um but anyway back back when things were
  • 00:20:12
    black and white we were in University by
  • 00:20:14
    the way we were at University together
  • 00:20:16
    if you've not heard that story but
  • 00:20:18
    anyway I won't bore you with it this
  • 00:20:20
    video is way longer than I was planning
  • 00:20:21
    it to be but the last very quick point
  • 00:20:23
    is the final thing you get is uh oh you
  • 00:20:27
    know what about the maintenance what
  • 00:20:29
    about Motors when they when they fail
  • 00:20:30
    they're going to be loads of money to
  • 00:20:32
    replace that I mean one of the benefits
  • 00:20:36
    of converting classic cars to Electric
  • 00:20:37
    is
  • 00:20:38
    you can use them as daily drivers
  • 00:20:40
    because there's no maintenance
  • 00:20:42
    reliability is like 100 maintenance is
  • 00:20:45
    literally zero but that's the thing with
  • 00:20:47
    electric motors there is so little
  • 00:20:50
    maintenance and that's a massive saving
  • 00:20:52
    yeah if I had a BMW or a Mercedes or
  • 00:20:55
    whatever and for those three is I think
  • 00:20:56
    how much money I would have had to have
  • 00:20:57
    spent on servicing it yeah yeah yeah
  • 00:21:00
