Cont: Electric Vehicles II

For the launch of the 2nd gen Leaf, Nissan took the journalists to the top of some mountain in the Canary Islands. The journalists drove the cars down the slope, going from quite empty to greater than 50% battery. I don't recall the exact figures, as you can tell
 
With one-pedal-driving it can be surprising. When I plan for a long drive where I know I will need to recharge along the way, I want to start with the best possible situation, so I've charged to 100% at home. In the first intersection when I come off the pedal and the car keeps rolling it's a surprise every time...

The same is also true when starting to drive with a car with a cold battery, when regeneration is not possible.
Some car manufacturers have solved this by adding the logic to the OPD, so that if the car cannot use regenerative braking, it will instead use the regular brakes simulate the same driver experience.

Tesla for example have not gone this route, so the car acts differently depending on battery temperature and SOC.

[ETA: fixed broken braking]

Even without OPD, my car flashes me a warning to say that regenerative braking isn't available.

Grrr. I keep forgetting that I don't have moderator privileges on this forum, so I can't correct "breaks" to "brakes" (which I do a lot on the car forum...)

Yea - well - Tesla does have a small symbol that shows that warning, but with the 3 or Y, that is of course not directly in front of you. (and yes - I should know better than to not check it...)

And thanks for pointing out my spelling - I've hopefully fixed it now - another thing I should know better...

I'm waiting for delivery on an EV6 now. I know that OPD has to be turned on for every drive in that car, so a different approach again.
 
Here’s the current implementation on my Tesla Model 3, with the explanation of what the “Apply Brakes When Regenerative Braking Is Limited” option means:

I can’t think of any good reason one would not select this option.

I agree - I sold my Model Y before that update arrived, so I haven't tried it, but I would definitely have tried it out.

The EV6 is probably like my Ioniq 5. You can't set it to default to i-Pedal, but you can set the default to Level 3 regen which is close. If you do want to switch to i-Pedal, it is just a quick pull on a lever.

ETA: I think the EV6 is similar enough that I can assure you that you will really enjoy driving it. :-)

Nice article here about Australian EV owners setting up a network to take their cars with VtL to help people in trouble after storm-induced power cuts.


Shame that most of the comments are just a load of sneering about "get a generator", spiced with erroneous statements about not being able to drive an EV through flood water.

Earlier this year there was a very large puddle on the A466 between Chepstow and St Arvans. I stood there for 30 minutes or so watching various idiots trying to "Clarkson" their way through the puddle in their ICE vehicles. Three had to be towed out of about 15cm of water probably with water locked engines.

No EVs were hurt in the telling of that weak anecdote.
 
There is a YouTube compilation of idiots taking a run at the Rufford ford in Teslas. In one case the water is half way up the windscreen. They all survived. One lost its front number plate.

In another YouTube compilation another idiot takes an MG4 for an actual swim in the Buttsbury Wash. It actually floated. That survived too.

Most of the fun in these compilations is people hydrolocking their engines and writing their cars off. No shortage of that. Not a single example of an EV coming to grief.
 
There was one of a BYD Sealion actually driving into a river and then 'paddling' out and returning (as in completely floating) rather apt given the name of the car lol

ETA, went looking for it, and found a completely different one of the E3 which can float for up to 30 minutes and paddle forward even!! (completely different one to the one I had seen before)
(all in Chinese unfortunately- 4 minutes long)

Some ICE cars are notoriously bad for hydrolocking if they even see so much as a puddle. Current BMWs seem to be very prone. A few years ago I came across a BMW 5 series stranded in nearly a foot of flood water, near the Waterloo bridge in Betws y Coed, with various onlookers pondering how to retrieve it.

I can hardly describe how smug I felt driving serenely past it in my tiny little MX-5, as I knew its air intake is very high up at the rear of the engine bay. As I said to my passenger, so long as the seals in the bottom of the doors don't leak, we'll be fine.

Any ICE vehicle where the exhaust pipe is below the water line is prone to hydrolock. Use to do a lot of off road 4x4 driving in a 1985 Jeep Wagoneer.(wish I still owned it) We modified it so both the intake and the exhaust entered above the roof line. I could submerge that car and the engine would keep running.
 
There are several videos on YouTube of people successfully driving Teslas completely under water.
 
When I was a full time mechanic we seen a lot of post flood cars with water getting into sensors and electronics if a unit wasn't sealed up right. After the '93 Mississippi River flood a lot of clean, low miles cars suddenly became available (all 93 or earlier) that nobody could get really running right again. Took a decade to sort those out of the market.

Cryslur continued that tradition into 2010ish where water could get into modules rather than full gulping down a river.

This was a real concern it appears mfg interests have fixed some.

I do hope that these new electronics intense cars have better modules than older cars did. Now if they go bad it could be dead rather than just running poorly.

I believe it. I would worry a bit about all those high voltage electrical connections and electric motors under water. But if they're sealed we'll enough why not? Almost certainly wouldn't over heat.

I absolutely hate the phantom electrical problems I have had with my Chrysler. I long for the days when the device was controlled by a relay controlled switch. Chrysler actually makes good engines. But are notorious for electrical problems.
