Regenerative braking is a feature that already exists in electric vehicles. With the regenerative braking feature, the electrical energy stored in the battery can be recharged as long as the car is used.
Regenerative braking in electric cars is integrated with the braking system. If the car is a combustion engine, the braking system will produce heat energy.
While the heat energy produced will only be wasted. In electric cars when braking, the electric motor component detects an active braking system.
Simultaneously the electric motor switches functions into an electric generator. The rotation of the electric motor which is faster than the rotation of the electric motor will produce kinetic force.
This kinetic force will be converted by an electric motor as a generator to be converted into additional electrical energy.
Some of the electrical energy will be stored in the battery, some will be stored in the electric motor.
Its function is when the car starts to accelerate again, the electrical energy used is from the electric motor and does not directly take it from the battery.
So that the energy consumption of electric cars can be more efficient by keeping the battery capacity from being drained immediately.
