I heard someone said that, at the end EV will cost you almost the same as gasoline vehicle, if you have to change the expensive battery every so often. Can someone please give me more info on this? Thank you so much.

I've had an EV as my only vehicle for about 5 years. The biggest cost of maintenance was replacing my tires. Then replacing one of the new tires after I ran over something and put a big hole in one of them.

The regular maintenance on it has been effectively zero. I don't have any fluids to change (other than windshield wiper fluid) or other regular maintenance tasks other than tire related things. My parents have had an EV for something like 8 or 9 years and their experience has been similar.

Do electric cars not have brake fluid? Should that not be being changed soon in it if you've had it 5 years.

[–] [email protected] 31 points 1 year ago (2 children)

I think they do, but you barely use your brakes due to regenerative braking. So you don't have to change it very often, if ever

[–] [email protected] 9 points 1 year ago (1 children)

Ah completely forgot about regenerative braking! I thought the main reason it needed changed was due to age and water absorbance rather than usage though, but again if regenerative brakes are used heavily then the regular brakes losing a little efficiency is a lot less of a deal.

Brake fluid is hygroscopic – meaning it absorbs water. It's typically recommended to change it every 2 years.

Not accounting for rust and weather impact, EV brakes systems last much longer due to regenerative braking from the motors being used before the brake system is engaged.

I wouldn't discount rust. I've had to change my rotors more frequently than pads due to rust (I drive a Prius). That said, I live in a state that oversalts their roads more than an amateur chef.

How often do you change tyrea? Also once a year? I always imagined that due the weight thetyres usage must be higher. Right now i work in a neighborhood with a lot of teslas and i saw that almost all their front tyres are absolutely gone.

[–] [email protected] 5 points 1 year ago (1 children)

If you live in a cold country it's twice a year to put winter tyres and then the summer ones.

Which you don't buy every time obviously, but still the change and storage fee is going to be about hundred Euros/dollars each time.

I found that a second set of rims and a splurge on an impact wrench paid for themselves in about 2 years.

Saves a ton over the life of the vehicle!

That's what happens when you don't rotate your tires. If you rotate them every 6000 miles or so, they'll be fine for a while. My stock tires are a year old and still look great.

[–] surewhynotlem 2 points 1 year ago

I've changed mine twice in seven years.
