Toyota Prius and Aqua has a mechanism that is able to capture the kinetic energy. This energy is then re-purposed into electrical energy.
Storage of Energy
Traction batteries store the kinetic energy. Electric systems use this power to perform necessary functions. Once you begin accelerating, rather than relying on gasoline, the motor is able to rely on this electrically generated energy because the motor was reversed during the process of braking.
VSC Vehicle stability control / Traction conrol
Hybrid cars have a complex system of ABS / Traction Control. It is also called VSC i.e Vehicle stability control. All systems are controlled electronically. To enhance life of ABS unit, brake pads and brake oil is timely cleaned . ABS can be permanently damaged if proper equipment is not used while working on the braking system.
