Automobile energy storage system utilizing solar energy and method thereof

Abstract

The invention relates to a renewable energy source technology, in particular to an automobile energy storage system utilizing solar energy and an automobile energy storage method thereof. The automobile energy storage system utilizing the solar energy comprises a solar cell unit, a primary energy storage unit, a secondary energy storage unit and a charging unit, wherein the charging unit is connected between the solar cell unit and the primary energy storage unit and between the solar cell unit and the secondary energy storage unit; and under the control of the charging unit, the solar cell unit can charge the primary and secondary energy storage units, and the secondary energy storage unit can charge the primary energy storage unit. According to the embodiment of the invention, the solar energy is stored in the primary and secondary energy storage units, so that the utilization efficiency of the solar energy is greatly improved. Moreover, redundant solar energy is stored in the primary energy storage unit, so that the phenomenon of deficiency of electric quantity after the long-term idleness of an automobile can be avoided.

Description

technical field [0001] The invention relates to renewable energy technology, in particular to an automobile energy storage system and method using solar energy. Background technique [0002] Traditional fossil fuel energy with limited resources and serious pollution is decreasing day by day, so clean and renewable energy with unlimited resources has become the focus of attention. Among them, solar energy, as an emerging green energy, is being rapidly popularized and applied due to its advantages of inexhaustibility, no pollution, and no limitation of geographical resources. Based on the principle of photovoltaic effect, photovoltaic technology, which uses solar cells to directly convert sunlight energy into electricity, is a very important technology that can realize the transition of mankind to a sustainable global energy system. It is generally believed internationally that in the long-term energy strategy, solar photovoltaic power generation has a more important position...
