In battery-electric vehicles such as Teslas Model 3, regenerative braking is the conversion of the vehicles kinetic energy to chemical energy stored in a battery,
which can later be used to power the vehicles own batteries.
Regenerative braking, using an electric vehicles motors to convert kinetic energy to electrical power for charging the battery pack
as it slows down the car, is the defining characteristic of electric cars.
Regenerative braking (abbreviated regen) is a cool system in which a drivers foot is released off the accelerator.
And the Teslas motor spins backwards to assist in slowing down the vehicle.
Having just picked up my Model Y, I saw the option of Regenerative Braking removed from all new Teslas, for whatever reason.
In yet another unexplained move, Tesla has apparently removed a menu option for changing regenerative braking levels on newer-built vehicles.
The salesperson explained that, sadly, Tesla had removed the ability to turn off regenerative braking with an October 2020 software update,
jokingly suggesting it was an driving experience drivers were adjusting to.
