Understanding Regeneration

Regeneration subtracts mechanical energy from the vehicle to generate electric energy; as a consequence there is a slow down in the speed of the vehicle (regenerative braking). The braking effect is quite different among Oppsing, Concurrent Regeneration and Dynamic Braking (please note that Dynamic Braking is just another form of regeneration, where the generator is shorted).
