Seems like EV manufacturers should set their cars to use the friction brakes for the first few stops of each trip, both to clean off the rust & dirt, and also to test whether they still work.
- malfist 2y agoAn electric motor is really good at arresting high rpm movement while charging, not so great at bringing low rpm movement to a stop. EVs blend together Regen and friction at slow speeds. That does wear off the rust.
- m463 2y ago> An electric motor is really good at arresting high rpm movement I don't think any EV that I've heard of has full-range electric brakes. There are two interesting kinds of things that I think EVs could use... brake resistors - if the battery can't absorb the full power of regenerative braking, maybe giant resistors can take the dissipate the rest of the energy. eddy currents - it might be cool to use eddy currents to brake. https://en.wikipedia.org/wiki/Eddy_current_brake https://en.wikipedia.org/wiki/Eddy_current_brake
- Scoundreller 2y agoMore advanced vehicles will also gently tap the brakes when you have your wipers on (or it detects rain) to keep them dry in case you need them.
