On my electric skateboards the brakes work by just powering the motors in reverse. If you dig into the motor controller software, it’s actually supplying the same amps used for full acceleration to perform a full stop. I presume the same could be done for cars, maybe that’s not so great for efficiency/heat in a large vehicle though. Just guessing.
