Regenerative braking
Slowing the car with the motor acting as a generator, sending energy back to the battery.
Regenerative braking turns the electric motor into a generator when you slow down, converting motion back into electricity and storing it in the battery instead of wasting it as brake heat.
It is the core trick behind hybrid and EV efficiency in city driving, where conventional cars throw away energy at every stop. A side benefit: friction brakes work less and often last far longer.
