Wind-solar complementary power generation system used for electric automobile

Abstract

A wind-solar complementary power generation system used for an electrical automobile comprises solar cell panels and miniature wind driven generators, wherein the solar cell panels and the miniature wind driven generators are arranged at the top of the automobile. A super-capacitor and a storage battery are installed on an automobile body. The wind-solar complementary power generation system further comprises a matrix converter. Energy generated by the solar cell panels and the miniature wind driven generators is transmitted to the matrix converter through a DC-DC converter in a one-way mode, the super-capacitor and the storage battery are in two-way transmission connection with the matrix converter through the DC-DC converter, when the energy of the system is sufficient, the super-capacitor and / or the storage battery supply power to the matrix converter, and when the electric quantity is insufficient, the super-capacitor and / or the storage battery obtain current from the matrix converter, wherein the solar cell panels are installed at the top of the automobile through rotating devices which achieve circular-ring rotation through gear transmission, and the solar panels track solar light by 360 degrees in the horizontal plane. The wind-solar complementary power generation system is applied to the electric automobile, in this way, solar energy and wind energy can be complementary, and an all-weather power generation function is achieved.

Description

technical field [0001] The invention relates to a wind-solar complementary power generation system for electric vehicles, which is mainly used in the technical field of electric vehicles. Background technique [0002] Due to the limited storage energy of the battery, the existing electric vehicle energy storage system limits the mileage of the entire electric vehicle, and the coverage of the charging pile is not comprehensive enough. When the electric vehicle is exhausted, it is difficult to move, causing inconvenience. Especially for electric vehicles for tourism, the top area is relatively large, the speed generally does not exceed 40km / h, and the running distance at one time is short; the existing charging method is plug-in charging, and the general charging time is 6 to 8 hours, which means During this period, electric vehicles cannot be used; moreover, a large number of electric vehicle charging will also increase the burden on the utility power system.
