Method and system for controlling charging of photovoltaic automobile

Abstract

The invention relates to the technical field of new-energy automobiles and discloses a method for controlling the charging of a photovoltaic automobile, which is used for controlling a photovoltaic cell or a generator to charge an accumulator. The method comprises the following steps of: detecting the voltage of the photovoltaic cell; judging whether the voltage of the photovoltaic cell is less than the charging voltage of the accumulator; controlling the photovoltaic cell to charge the accumulator if the voltage of the photovoltaic cell is not less than the charging voltage of the accumulator; and controlling the generator to charge the accumulator if the voltage of the photovoltaic cell is less than the charging voltage of the accumulator. When the photovoltaic cell has larger generated electricity, the photovoltaic cell charges the accumulator; when the electric energy production of the photovoltaic cell cannot meet the charging requirement of the accumulator, the generator charges the accumulator; therefore, both oil consumption and the using cost of the automobile can be reduced; and the normal operation of the automobile in any case can be ensured. The invention also discloses a system for controlling the charging of the photovoltaic automobile.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a photovoltaic vehicle charging control method for controlling photovoltaic cells and generators to charge storage batteries, and also relates to a photovoltaic vehicle charging control system. Background technique [0002] With the development of science and technology, cars have gradually become an indispensable means of transportation for people, and the number of cars held in the whole society has also continued to increase significantly. [0003] The power required for the car to walk mainly comes from the engine, and the engine provides the power required by the car's walking system by burning fuel. In order to improve the comfort of the car, electric equipment such as audio equipment and car lights are usually installed in the car. In order to enable audio, lights, various instruments and other electrical equipment to work normally, a generator and a vehicle b...

Problems solved by technology

[0006] However, the power generation of photovoltaic cells mainly depends on the intensity of solar radiation. The power generation of photovoltaic cells is unstable. Once the intensity of solar radiation is low, the power generation of photovoltaic cells will also become smaller. When the power generation of photovoltaic cells is small, It will not be possible to charge the car battery. When the power in the car battery is exhausted, various electrical equipment in the car will not work normally.
