The Truth about EV Battery Life and Charging Best Practice ! | 4K

So what is the fact about battery life and charging finest practice? Are they done after a number of years? Does fast charging damage them? Should you charge to 100%?

Well I paid my mate Moggy at Electric Classic a visit so I could de-bunk the myths and misconception. This video is a must for any owner.

    Even without battery temperature management our 2013 Renault Zoe 22Kw got to nearly 100,000 miles and the battery loss was only 9% from new so not too bad either and although we have now sold it (2 years ago) its still going fine as I keep in touch with the new owners.

      The Zoe had active air cooling in the battery.The Leaf had passive cooling and that caused the problems.

      Guess the fact the you can’t DC rapid charge the battery helps with longevity.

      @Humphrey Bradley The Continental version of the motor in the Zoe could be charged at 43 KW on AC.The fans would work hard when that was happening.

      Not sure how much of an “old git” you are lol but I bought my first EV at 63, best car I have had, 22,000 miles a year, sometimes 400+ a day, saved me a fortune!

    Gained a lot of respect for you over these last couple ev videos. You are keeping an open mind, but also a healthy dose of ev skepticism.
    Combined with your own real use experiences and very honest open conversations with actual industry experts. Top shelf stuff imo. 👍🏻😎

    My issue is the infrastructure – we are not allowed to charge an EV at home and there are no chargers within 5 miles (and they are also never working). As my wife is disabled we cannot ever have an EV, and it looks like this will be an issue in many flats/social housing as well

      @Jonathan Vogel no off road parking, multi occupancy properties & not enough voltage capacity/infrastructure in some larger urbanised areas. Some electricity supply companies can turn down applications for charger installations

      But that is not an EV problem, it is a landlord / infrastructure problem.

      Also, how do you know your local chargers are not working because you don’t have an EV? I simply do not believe that you go and check them daily.

      Simple question: How many miles do you drive a day (or a week)? In the Uk the average daily mileage is just 20 miles per day. A typical modern BEV with a battery of around 50kWH can easily do 200 miles, that means you would have to charge only every ten days! If you do less mileage than this, then there is an even longer gap between charges!

    Thank you Pete and Moggy. You have answered a load of important questions. Why don’t manufacturers advertise this as at the moment EV’s are bad money at the moment (I work in the motor trade at a main dealer)

    Interesting video ! Having recently purchased my first EV (Cupra Born) a month or so ago through a salary sacrifice in work it’s reassuring to hear someone who knows what they’re talking about for a change.
    I’m not able to charge at home but do have access in work and found local public charging reliable so far.

    My other half bought an MG4 on NHS lease scheme it’s brilliant and she loves the car and this is from a person who has no opinions on cars !! Excellent video great to see moggie again he needs to get him self on the fully charged show have a chat with those guys as they are on a mission to bust all of the miss information about electric cars and it’s a great channel as well.
    I must admit I am now looking to get a battery car myself and I am a real petrol head !!!!!

    Great video, Pedro. You and Moggy have a great rapport. 😊

    One thing Moggy forgot to mention, though, is the difference between gross battery capacity and useable battery capacity. Most EVs have batteries with built-in top and bottom buffers to protect the battery from ever being 100% full or 100% empty. Another reason degradation is now so low. For example, the Tesla Model 3 long-range has a gross capacity of 82kWh, but the useable capacity is 75kWh.

    Thank you, that was quite interesting. Could you please also cover other potential issues in one of the future videos?

    Flammability – If I’m not mistaken close to a 100 EVs catch fire every year and while it’s not a huge number it is concerning as batteries burn at incredible temperatures. In a densely-populated urban setting it feels like the damage could be extensive.

    Repairs – while you did mention that reliability of battery packs is pretty decent already and only gets better, what about the cost of replacing the battery pack after damage or crash? Petrol engines have many moving parts but there’s plenty of those about and you can get a replacement without essentially buying a new car. What measures are there to protect the battery, other than insurance that is? But also, would this make your insurance go through the roof if you claim?

    Software – the beauty of petrol cars is that only some brands have pesky little pay to use feature limitations. With EVs it seems you also need to maintain a subscription plan to get the most of it (or so I’ve been told is the case for Tesla at least), and the price is only limited by the greed of the manufacturer.

    Security – my petrol car has literally zero connectivity (at least without a phone paired) and can happily function without software updates. As far as I understand it’s not the case with EVs where software is king and runs everything. Surely this will introduce certain issues down the line where software is no longer maintained and your car can become easy prey to hackers (like the rise in the keyless car thefts we’re seeing lately)? Smartphones have been pretty bad at it with hardware support being dropped only a few years down the road.

    Pay-per-mile and overall cost – the gov is planning to charge EVs per mile. At the rate of 9p per mile my daily nursery/school run will cost me £1.5. That’s £30 per typical month and probably equivalent to half a tank of petrol so it is not as bad as petrol, but you also have to pay for electricity. Home charging is cheap, but public charging can easily cost you £20 for 30 minutes. In conjunction with the much higher initial cost it’s starting to feel like not such a great deal even if battery pack lasts a decade. Plus you have to actually fork out for the installation of the home charger.

    Again, thank you for the great video, I’ve learned quite a bit.

      Around 160’000 ICE cars catch fire each year in the US……

      Flammability – We seem very happy to ride around with 60 or 70 kg of explosive in a tank typically measuring less than 0.7mm in thickness and mostly plastic these days, the protection plate of batteries far exceeds this and the latest battery tech does not suffer when pierced. This will only get better.
      Repairs – Insurance always go through the roof if you claim, but the batteries are typically protected by high grade steel and any impact that affects the battery will no doubt affect the chassis and safety cell structure.
      Software – My ICE VW has had three software updates on recent services, everything has multiple PC’s to run everything through a canbus since around 2006 when OBD2 became standard. EV’s are no different.
      Security – See above on software but legacy support is typically good in the auto industry and third party software is also available, even now.
      Pay – per mile – The flat rate of £180 a year from 2025 is already in motion for all EV’s and I have not seen any reports of the 9p/mile surcharge, 6p/mile was bandied about by Telegraph readers, but it’s not going to happen according to fleet and OEM insiders since the government has committed to the flat rate.

      I don’t have an EV, I have five ICE cars (mainly classics and raw bike engined fun stuff), but have worked on various BEV projects and Hydrogen projects for OEM’s as a Quality Manager on process and project validations and homologation. I will make the move very soon though, as I now believe the thermal management and power density is acceptable to ensure long term use without too much weight penalty. I am not one to finance my vehicles, so even as an “insider”, I had to be confident for my next purchase as I tend to run them for 10 years.

    Great review, had two Tesla cars over last six years, never paid for a service and the battery Managment limited battery deg to less than 8% on both 👍

    Thanks for such a helpful content. When I bought my EV, the dealer said to charge from below 20% to 80% on fast chargers but up to 100% on the home charger wouldn’t harm or degrade the battery any faster, so that is what I am doing… however I will, change to the 20-80% cycles at home from now on…. I do make a record of every charge… to include: date/ location/ starting and ending percentage/ kWh input/cost. I do this to show how I have managed the battery when I come to sell the car… also for my own interest in checking range stats, which for my MG5 is better than I expected… thanks for the great videos… 🙂

    Welcome to Wales! That rain on the roof of the factory unit is epic.
    As others here have said, it’s great that you have adopted a balanced view of all types of car, and I appreciate the fact that you openly state the best car you’ve driven for your personal circumstances is your present 3 litre diesel Land Rover defender 90. I wish I could afford one (but not in the tomb raider spec like yours) because the 90 looks like an awesome car that would suit me perfectly.
    Full kudos to Moggy also. I love his channel and am a subscriber.

    My biggest worry, apart from a bit of range anxiety this coming weekend – is the changes to charge plug standards.

    My 7 y/o Soul has a Type 1 socket – and a Type 2 adapter, now I hear Chademo is on the out as well – what is going to be needed to keep older EVs going when all the public chargers have a new socket standard (type 3 ??); can new sockets be retrofitted? And what are the costs of that going to be – I assume the onboard charger circuitry is going to need changing, not just the actual socket – at least for the Chademo replacement.

    Obviously, what is going to happen in a few years time, when my tiny 27KWh battery degrades too much, is also a concern; with no official KIA offering, will I be looking for someone to fit a customised Tesla pack ??

    Meanwhile, I love “My Car Totoro”; he has put some enjoyment back into driving, even at sedate speeds.
