All discussion of EVs (and hybrids for the moment), charging networks, etc, welcome!

No USA/Americas news unless it is relevant to the UK/Europe - most of the existing EV communities on Lemmy are awash with US discussion, please use one of those. US news and discussion will be removed.

I don't really see the point of this. It's just adding complexity for the sake of it. As far as I can tell when you change gear it just changes some software parameters, there are no physical gears. Yet there's a clutch and the ability to stall?

Why? This makes no sense. Electric cars don't need a transmission, they are direct drive.

My car has a CVT and it has shift paddles that are totally unnecessary.

They also add a delay between “gears” because there was too many complaints that the vehicles wasn’t changing gears.

Yeah people are stupid.

Is that what it is? I feel a bump at 80km and always think "CVT my ass"

[–] schmidtster 2 points 1 year ago

The paddle shifters have a usecase, it allows you to select portions of the cvt to increase acceleration or reduce road noise. The point of the cvt is to keep the vehicle at the most efficient rpm for fuel, which unfortunately is rather high and noisy.

If you're in mountains, and especially if you're towing a trailer, you need those.

I don't know about trailers, but my EV makes light work of mountains.

Is my comment showing up as a reply to the one about CVTs with paddle shifts because that's what it's in reference to. I feel like kbin has been putting my replys in the wrong places.

With all the trque and regen EVs should be fine in hills even with trailers.

Isn't that what the brakes are for?

[–] [email protected] -1 points 1 year ago

On a long down hill if you use your brakes too much you risk brake fade and glazing. With electric you need regen or if you have no more room in the battery then you need resistive braking. With an ICE you need to be able to lock into a lower gear. Standard behavior eith a cvt is to gear as high as possible when not under load so you need "manual mode" and the fake gears to pick a ratio with good resistence.

You should be using the regenerative braking…….

I was just thinking that a cvt would be better for an ev...

They don’t need a transmission at all though

[–] ilovesatan 2 points 1 year ago

It's not a real transmission. It's a fake clutch and stick. Both are tied to the computer to make it feel like you're shifting.
