VS - Electrical Systems From Stop-Start to Hybridization

Benefit from vehicle kinetic energy What is the kinetic energy? A body in movement generate a so called kinetic energy (E); the amount of energy depends on: ●● the mass M of the body, the heavier the higher amount of energy ●● the speed V, the faster the higher amount of energy

Kinetic energy can be basically experienced by car occupants via the seat belts pressure during sudden braking.

3600 Joule = 1 Watt*hour

The standard unit for kinetic energy is the Joule (J)
