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 wave power generation system comprises a hydraulic motor for storing motion energy in a form of fluid pressure and volume if a plurality of tension transmission members, for transmitting motion energy by means of six-degrees-of-freedom motion of a movable object floating on the waves, move in one direction, and for maintaining the tension of the tension transmission members by means of the stored energy if the tension transmission members move in the other direction. Electric energy is alternately generated by means of the bidirectional motion of the plurality of tension transmission members.
