This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus comprises a driven mass, a generator, a charger, a hardware controller, and a communication circuit. The driven mass rotates in response to a kinetic energy of the vehicle and is coupled to a shaft such that rotation of the driven mass causes the shaft to rotate. The driven mass exists in one of (1) an extended position and (2) a retracted position. The generator generates an electrical output based on a mechanical input coupled to the shaft such that rotation of the shaft causes the mechanical input to rotate. The charger is electrically coupled to the generator and: receives the electrical output, generates a charge output based on the electrical output, and conveys the charge output to the vehicle. The controller controls whether the driven mass is in the extended position or the retracted position in response to a signal received from the communication circuit.

The range extending type driving system taking the range extender (10) as a power source and/or the battery swap type driving system taking the quick-swap battery (20) as the power source can be freely and flexibly switched according to a use scene and economy to drive the vehicle to travel.

An electric vehicle which operates from a rechargeable battery. The rechargeable battery is contained within an enclosure such that an airspace exists between the rechargeable battery and an interior wall of the enclosure. An aerosol container containing an aerosol electrical insulator communicates with the interior of the enclosure so that when said aerosol container is discharged, the aerosol electrical insulator is released within the airspace to dampen any fire occurring with the rechargeable battery.
