  • the series hybrid incorporates an electric motor, capable of driving the vehicle transmission individually, using battery pack energy when available, and using electric energy generated locally when the battery pack energy is drained. Electric power is generated by a separate internal combustion engine running on fuel, coupled to an electric generator.
  • Hybrid systems use regenerative braking where braking power is transmitted to electric power and stored in the battery pack for later use.
  • Hybrids are intended to reduce pollution and noise and to increase efficiency and travel range per liter of liquid fuel, whether gasoline or diesel fuel.
  • the travel range is influenced as function of load weight, road topology, environmental temperature and drive conditions.
  • Hybrid systems by nature increase the total range of travel of a given vehicle by means of generative braking, higher efficiency in operation, lighter engine and reduced volume of the fuel tank.
  • the operator can override the battery management system and heat or drain the battery to an extent that may degrade the battery life or energy storage capacity.
  • Liquid cooling systems can be distinguished by use of electric conductive or electric isolating coolants.
