WebRegenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. WebOct 26, 2016 · Using such a motor as a regenerative braking system would produce AC power, wouldn't it? Now charging batteries from an AC power source requires a charger, which is essentially a rectifier, to convert to the DC current needed by the batteries. It seems like the conclusion is that the charger needs to be used during regenerative braking.
