Teslas semi does not also have regenerative braking, which takes the energy out of braking and uses it to charge its batteries.
Like many other EVs, Tesla uses a clever mechanism called Regenerative Braking.
Tesla vehicles also use their electric drive motors as a brake, since they produce energy and slow down the vehicle.
Brake energy recovery, which recaptures kinetic energy and stores it as electricity in the battery pack, naturally slows the Tesla Semi Electric truck.
Electricity and energy are primarily focused on getting the wheels moving, not by burning electric energy.
Tesla then uses a regenerative energy system to extend the range of Teslas new Semi truck,
Its semi truck has three electric motors, with one driving the truck for the majority of its drive
while the other two are used mostly to accelerate and push harder.
In November 2017, Tesla CEO Elon Musk said the Tesla Semi will have four of the same type of electric motors used by the Tesla Model 3.
