    Flooding and electric cars.....?

    The pictures of the flooding in many areas due to storm Dennis are awful and it must be difficult for lots of people.

    I just wondered how electric cars react in these conditions - particularly the batteries - are they volatile if they are subject to water ingress...?

    Good question, and as most electric cars have the batteries stored in the floor, whatís happens should you drive through deep water.

    Although no trees were harmed during the creation of this post, a large number of electrons were greatly inconvenienced.

    Great, now they'll all be hiking their prices based on their ISO rating and whether they can put 'Divers' on the boot. Why buy the Tesla P85D with 600m WR when the P90D comes with a cool 1000m WR.

    Do they need an isolation switch...? Could they short out?

    Sure I read somewhere the battery and motors where ip66 rated , if so they are pretty safe in a Flood .
    Ill try and find a link

    I was booking my Honda Civic in for a service a couple of years ago. The sales guy told me a customer with a £15000 CRV had his car written of the previous week. Saw a flooded road, owned a 4WD so went for it, flooded the engine trashed the electronics, game over.

    Everything is well sealed.

    I drive my e-Golf happily through much deeper standing water than I ever would have the GTI or GTE I had before.

    Subject to the same risks as any car though if its flowing water, although the e-Golf is a fairly heavy beast.

    What happens to all the electric street furniture when a flood submerges it? Not much is the answer.

    That is indeed the right term - covers a lot of stuff including (but not limited to) - lighting, illuminated signature, uplighters, vehicle charge points, marker trader pillars, bus shelters and now smart city stuff. So you learnt something new - who said the internet was a waste of time.

    Ha. I stand corrected. Stubborn as I am, I'll still think of furniture as a chair though. Vehicle charge point my ass.

    Years ago, I was driving in to a local town and the road was flooded. Cars in front started going through the flood, there was a huge queue of cars behind me, so I had little choice but to go for it.

    Half way through the appx 70 metres of flooded road the car in front of me conked out so I had to stop. A small thud and my car, a Jaguar S-Type R just died.

    That thud was the sound of nearly 20k of damage being done as the engine was destroyed and even the xenon headlights somehow had water blown through them.

    The car was only about three years old, and they wrote it off.

    I haven't made the same mistake since...
    So clever my foot fell off.

    On the bbc website, a picture of a flooded street shows several cars, abandoned to the water, with the hatchback open. Would this be an automatic safety feature do you think?

    Probably a law against it. ;-)

    Maybe itís to let water in rather than have them bob around and float off?

    Electric vehicles should be much less susceptible to flooding when compared with an ICE car - far simpler mechanicals, easy to seal, no air intake, no fluid lock issues, no exhaust gasses to expel, etc..

    Not always the case. Isnít there a youtuber who has purchased several flood damaged Teslaís and when I watched his video water had got in everywhere including the motors.

    Donít understand why owners donít park them elsewhere if flooding likely - insured so donít care?

    I had to drive my EV through about 8 inches of water last Sunday when the north circular flooded which I did with some trepidation! It was fine, though I have since read in the handbook that you shouldnít go through water that is higher than the underside of the car and this was probably about that deep.

    No problem so long as the charging point cover is screwdown

    Any water that breaches the sill height on an electric car (or hybrid) will write it off.
    ...donít ask me how I know!

    Hence the ďshouldĒ - my point was thereís no reason that EVs canít be equally or more resilient to flood water ... whether they are or not ... also you might argue Tesla arenít a traditional car manufacturer so may not bring that sort of experience/thinking to their designs, so their carsí resilience or otherwise is not I think indicative of all EVs.

    (Equally I donít know - I have no personal experience of EVs - Tesla or otherwise.)

    The greatest risk is being swept away and the the floating properties are the limit. An e-vehile is as less likely to float as it is heavier because the floor is not hollow but filled with heavy bits; adds no buoyency.
    When the going gets tough, the DAF gets going.
