Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0034] Because the use of solar energy as power will not pollute the environment, and solar energy is also an "inexhaustible" energy source, so the present invention provides a vehicle multi-energy supply system and method, using solar energy as a preferred energy source for vehicles To provide driving force, and considering that the position of the solar battery mounted on the car is constantly changing due to the high-speed driving of the car, resulting in instability of its output power, so the battery and super capacitor are used as supplementary energy for solar energy. When the maximum power provided by the solar battery cannot meet the driving power required by the traction motor, the insufficient part wil...

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 ...
