The Reality of EV Battery Crashes: Real Test Results

Are electrical vehicle batteries actually safe in an auto accident?
Ginny heads to China to see how Zeekr are security screening and engineering battery tech to withstand high-impact accidents.

The results of the test spiked a lot more fascinating discussion around insurance costs for EVs, so Ginny heads to Thatcham Research study to speak investigate further …

    The price decreases will never come. The existing premiums are normalised so there will never be an incentive to reduce.

      Why reduce… when they can sell with current prising…

    My last EV had a woman in an Audi Q something SUV slam into the back of it. I was stationary and she was doing 60 or so. My battery was fine, the fire brigade disconnected for safety but despite the rear of my Ioniq being obliterated, the battery looked absolutely fine

      Yes batteries nowdays are very safe.

      ​​@NcS-f4e Cars ends are made to crumple now, ensures less force reaches the core, where people and the battery are located

      you idiots turn everything into a culture war, if you actually liked ICE so much you’d just get one instead of blabbing nonsense

    I read that China now requires accessible door handles so the doors can be opened even if the battery is wrecked. It’s so emergency crews can get people out.

      It’s a good rule to have, extraction is incredibly important. Some manufacturers are working on smarter ways to make cars, and EVs specifically, safer every year

      ​@Electrifyingcomthen why didn’t you point out that in the car tested in the video the handles remained flush?

      @LukeSkywalker-nq8pb Why would they? The video was about batteries!

      @LukeSkywalker-nq8pb

      ​@ragetobefair enough, however I’d argue that the information about door handles remaining flush in case of a controlled crash test is a rather poor prognostic for their behaviour in case of a real world crash where the battery might actually ignite.

    1:41 Appreciate you mentioning that you are testing the LFP battery which is safer than the more common NMC lithium ion battery. Details matter.

      That they do! Which isn’t to say NMC batteries can’t be safe too, of course

      ​@ElectrifyingcomChina’s new standard for all batteries of any kind to not propagate for from one cell to another applies to all new batteries of any chemistry. They’re all quite safe now.

    Some stats from Norway: EV car fires have gone from the media because of reality: 1) Fossil cars catch fire at a 4-6x statistical ratio. 2) Norwegian fire departments have fixed the “EV fire” by cooling and removing the object, then do long-term cooling. 3) The origin of fires are largely not caused by the battery (it is the 12-volt system/fabrics/plastics etc that tend to start them). 4) There is no surge in EV battery fires with mass adoption of EVs – the rate is flat or sinking.

    Here is how Norwegian fire departments look at it: It takes 2x the time to fully put out an EV fire compared to an ICE fire, and it takes 2-3 times more water to get it under control. Explosive danger is very low, but one must “quarantine” the EV for days (due to reignition danger).

    The biggest issues are electronic door systems, etc (that may prevent passengers from getting out once the 12-volt system goes out), since an EV fire is not explosive but evolving. There is also toxicity (but similar awareness is required for ICE cars, as any car fire involves gases nobody wants to breathe).

    Some unique risk assessments must be made: As Norwegian tourist brochures correctly state: See Norway from the inside (most of our roads seem to be inside mountains/aka tunnels). And if you are not in a tunnel, you are on a ferry: Rapid isolation and cooling in densely packed places is important – but hey – the same is true when an ICE car lights up on a ferry or in a tunnel too.

    “Norwegian institutional assessments conclude that EVs are structurally safer for occupants in a crash and significantly less prone to catching fire spontaneous or otherwise”.

    In terms of accidents, Norwegian data show a slight increase (10% higher than for ICE) in the risk of minor (fender bender) accidents with EVs. They attribute this to a combination of “the masses” not being used to the instant torque and power output of EVs (even low-power EVs do the zero-to-twenty quickly compared to “your last car” (typically a 1.6 diesel) and (to no surprise) people navigating the massive screens instead of driving/navigating the car.

    Since Norway has a car fleet that is ca 30% fully electric and 70% hybrid/diesel/petrol, Norwegian statistics are a valuable peek into the future for most nations. Remember, out of the total distance driven in Norway by “private type” vehicles, 36.66% of the total national distance driven was done with pure BEVs last year; thus, the statistics are robust (aka – Norwegian EVs are not just “city cars running short errands” or other things that can skew statistics).

    Thus, if you want to create huge indoor parking house 400 kW stations (etc) – just call a Norwegian colleague (since some special considerations are coming into play for that – hinting at why we do not have petrol stations inside parking houses – it is never zero risk).

    PS…that massive parking house fire that was reported across the world in 2020 – it started from a parked diesel car – and Norwegian fire departments were still figuring out how to best handle EV/mixed EV+ICE fires indoors. (Bless anyone happy to figure out how to best walk into a parking house while diesel and petrol tanks, oil and camper vans with propane gas canisters, batteries, plastic, carbon fibre and the entire car park structure have been at full blaze for 20 or so minutes).

    Drive safe, everyone – and remember that the main problem is the random driver who is busy sending a text or doing some other weird stuff.

    insurance companies base their prices on last years payouts. they don’t make losses .

    My BMW i4 was whacked off the road by a lorry. Went into a ditch backwards at 60…. police cut me out, the car saved my life… if id been in my M4 i would be dead….. it did steam a bit in the scrappy, CAT A… no fire, just safety….

    I’ve said this a number of times to people worried about this: the battery is the toughest part of the car. People get so worried about the battery failing in a crash that they don’t realise that it’s built to withstand an impact, and it’s placed underneath the car, between the wheels, meaning that the only way to pierce the battery is either to subject the car to a crash so hard nobody would survive it, or to drive a pneumatic spike straight into the car from beneath. By comparison, a petrol car has fuel lines right next to a red hot engine by necessity, so realistically, a petrol car would be many times more likely to catch fire.

    New Chinese battery safety standard is after severe piercing damage, batteries aren’t even allowed to smoke let alone burn. Addition with the mechanical door handle, EVs are gonna be the safest cars on the road. Every major EV brands are forced to follow this standard if they wish to sell in China which is the biggest car market in the world.

    So that was something the weight of an empty Ford Focus hitting a much heavier object on a low friction surface. The door handles didn’t pop out either so how were they opened from the outside, by someone leaning in through a window and pressing the button? Or am I missing something?

    The only backup system on the 7X for releasing the door from the inside if the power fails is a pull lever that releases a preloaded spring pin to break the window btw.

    When I got my Tesla RWD, Model Y last November LV+ wanted £85 extra to insure me until the policy ran out on the 1st of Fab. Fair price, I thought. But then wanted twice the cost of my Honda CRV HEV for the same Tesla, for this year. So I shopped around. I’m also an advanced driver with the Institute if Advanced Motorists. LV+ weren’t interested, but a company from Belfast, Cornwell, did insure me for £120 quid less than the cost of my Honda. So I paid just under £400 for the same cover for my Tesla. It pays to shop around! (And be an advanced driver!)

    Why is that Zeekr 7X not crashed by a car with a realistic weight of at least 2000 kilos? Nothing weighs 1350 kilos now a days.

    Just bought my first EV, a brand new Renault 4 E-tec which I’ll be taking possession of next Saturday, and the insurance cost is pretty much the same as my soon to be replaced 2013 VW Golf TSI. Given that the Golf is in group 13, and the R4 is group 27, I was shocked at how cheap it is to insure.

      how much was it ? i pay 180 € rn and later 130€….

    Just under two month’s ago I crashed my EV in a stupid situation where the sun blinded both me and the EV radar (road incline artificially lowered the angle of the sun) which then made the cruise control think the road ahead was empty (and thus accelerate) while I wasn’t able to see the dials on my dash for a moment and thus only noticed the acceleration due to inertia pushing my body into the seat.
    That will have delayed my reaction speed by just enough that me slamming the brakes wasn’t quick enough.

    Crumple zone took most of the impact though and battery was completely okay.

    100 years of data? Why would an insurer care about cars but in 1920 to price insurance?
