Vehicle multi-energy supply system and method and solar energy car

Abstract

The invention discloses a vehicle multi-energy supply system and a method and a solar energy vehicle. The vehicle multi-energy supply system comprises a solar energy battery module, a storage battery module, a super capacitor module, a DC-AC inverter and an output control module; the output control module is used for acquiring the current state of a vehicle, the output control module controls any one or more modules of the solar energy battery module, the storage battery module and the super capacitor module to output an direct current to the DC-AC inverter according to the current state of the vehicle and the respective remaining capacity of the solar energy battery module, the storage battery module and the super capacitor module, and the solar energy battery module outputs the direct current to the DC-AC inverter preferentially; and the DC-AC inverter is used for converting the direct current into an alternating current to drive a traction motor. According to the vehicle multi-energy supply system and the method and the solar energy vehicle, environmental pollution caused by the vehicle can be reduced, energy using efficiency is improved, and vehicle driving range is increased.

Description

technical field [0001] The invention relates to the field of vehicle energy, in particular to a vehicle multi-energy supply system and method, and a solar vehicle. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four types, namely hybrid electric vehicles, pure electric vehicles (including solar vehicles), fuel cell electric vehicles, and other new energy (such as high-efficiency energy storage) vehicles. [0003] Most of the existing new energy vehicles use a single energy system. Since each new energy has its own limitations, for example, chemical energy batteries have low energy storage density, shallow discharge depth, and short service life. Flywheel batteries have high power density and energy The conversion ...

Problems solved by technology

However, due to the weak and unstable solar radiation intensity and low conversion efficiency, solar cells on cars are mostly used as a supplementary energy source at present. In many cases, car electrical appliances still need to rely on the car's generator and battery energy storage.
