Electric Vehicles (EV) Thread

[Dannie Boy]

Seems like it isn’t a significant risk?

A new question. Are BEV's more restricted concerning water depth on the roads than ICE's? That's a valid concern here.

I would imagine with the electric motor it would be sensitive to splash, spray, snow much more than an ICE vehicle.

As mentioned in that link, if it complies with the IP ratings listed it will not be a problem. The motor is probably the safest part, as it is common to seal motors to IP 65. The life of the various seals, gaskets and insulators would be of more concern to me, especialy in regards to the high voltages in use.

To be completely immersible it would need to be IP 68.

I'm unfamiliar with other brands, but 2022 MG ZS EV 'battery pack' is rated at IP69K. Motor, TBH, haven't a clue, but I won't be driving through any floor board deep water, or any over the lower part of the tire. Don't know why anyone would want to test that, or ever drive their car though water deeper than lower rubber of tire

I've had to replace wheel bearings (obviously unsealed) on other vehicle here in TH, lesson learned, so I avoid most deeper water. Yes, that would be an issue for folks at Krung Thep or other cities with poor drainage after a downpour. Not an issue for myself, as retired, and don't need to be anywhere at anytime. Though the seawall at PKK was breached last week, so I guess I wouldn't have drove on the surfside road till that receded. Was at Krung Thep anyway.

An aside, the earlier version, MG ZS EV (2019 ?) got a 5 Star crash rating in Euro test...
... "The MG ZS EV has scored a full 5-Star safety rating in the Euro NCAP crash test for frontal, frontal off-set and side collision while the 5-Star also imply that it's body has been rated stable."

Side impact probably being the most important, so guessing the EVs should be pretty safe, as needing extra, to protect those battery packs.

Still on the subject of EV's.
My daughter spends half her time in the US. She recently returned and was telling me that when ordering a taxi, a car turned up without a driver. "It's really weird. It takes you to your destination even choosing alternative routes when traffic demands it. Plus of course these cars are all electric"
She was in Austin, Texas. Apparently it's around in several major cities.

The video shows how it works.

I’m not sure I’d fancy that!!

My daughter says that initially it's quite scary but after you've made a couple of trips you get to expect it and apparently it's safety record out of a couple of million miles produced just 2 minor accidents with no injuries and the fault was on the 'other' driver.

[Dannie Boy]

I’m sure you’re correct, but I don’t think you’d get me in one of them!!

There's a famous, permanently flooded ford in the UK called Rufford Ford. If you search on YouTube there are dozens and dozens of videos of different vehicles trying to get through. If you watch a bunch of these, you'll notice that the only vehicles that routinely get through without a problem, no matter what, are high clearance SUV's or 4x4 vehicles and Teslas (there are hardly any other EV models in the videos that I've seen for some reason).

Here's a compilation of Teslas, all of which make it through (though a couple lose a number plate).



And another compilation showing a majority of ICE vehicles not making it through successfully.



Whether other EV's batteries are as well sealed as Tesla's, I couldn't say for certain - maybe someone more knowledgeable could comment.

It's in Nottinghamshire, not so far from where I was brought up. In the nineties, I had a Land Rover and I used to drive through it a couple of times after offroad days to get the mud off.
If you watch some of those videos of Tesla's going through it when it's particularly deep, they actually float for a few metres in the middle and just carry across with momentum.

I've actually seen an article saying that tests have been done showing that Teslas that had their doors sealed with waterproof tape can 'drive' for some distance while floating on water, with the wheels acting as propellors to move them forward - you can't steer, though.

[GroveHillWanderer]

OK, couldn't find that article, but I did find this one. So maybe I misremembered and it wasn't tests as such, but just real world examples that showed this is possible.

This isn't the first time we've seen a Tesla practically working as a boat. CEO Elon Musk said the Model S floats well enough to act as a boat for a time. He even explained that you can propel the Tesla through the water via "wheel rotation." However, please understand that he said this is not recommended.

^There is a new BYD SUV hybrid in China that has an emergency floating mode:

YangWang U8 launched, can float on water for 30 minutes and sail 3km/h

...."When activated, the combustion engine will immediately shut down, Disus-P will raise the suspension to the maximum level, windows will be closed automatically, A/C will be switched to internal circulation, and the sunroof will open, providing an emergency exit. Moreover, the vehicle will display the water depth and attitude on the central control screen."......

If you're driving in a flood it's reasonable to think there is also a driving rain storm going on. I hope there is an override to close the sun roof.
