A vehicle-mounted solar power generation device includes a solar panel, a solar battery that is a battery temporarily storing electric power, and a controller configured to perform control by switching between an electric power generation mode in which the solar battery is charged with a generated electric power of the solar panel and an electric power saving mode in which at least the charging of the solar battery is stopped such that power consumption is suppressed in comparison with the electric power generation mode. The controller determines to switch between modes based on the output voltage of the solar panel. In the electric power saving mode, the controller restricts a switch to the electric power generation mode based on any of the frequency of switching between modes, the amount of electric power stored in the solar battery, and the state of stoppage of a vehicle.

Aspects of the present disclosure are directed to systems, devices, methods, and computer-readable storage medium for adaptive/dynamic thermal management of an electrical power system having variable electric loads, and components thereof. Thermal management may be driven at least partially by predicted/modeled thermal performance of the component to be managed, which may be calculated or modified using direct or indirect measurements. Embodiments may include adaptive thermal management of at least one of an energy storage system and an electric energy supply. Applications of this disclosure may include adaptive thermal management method for electric vehicles and non-mobility applications, particularly having variable electrical loads, which may impact performance or life of the application.

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.
