The control system is connected with the charging system. The control system comprises a microcontroller module, a TL494 control module, and a drive module. The power module comprises a first power module and a second power module. The solar battery temperature detection module is connected with the solar battery and the microcontroller module. The beneficial effect is that the vehicle-mounted solar charger for an electric vehicle with the advantages of high tracking response speed, large range of output voltage and stable performance is provided.

Description

technical field [0001] The invention relates to solar energy utilization and electric vehicle power battery charging technology, in particular to a vehicle-mounted solar charger for electric vehicles. Background technique [0002] At present, the worldwide energy crisis and environmental pollution make people of all countries strive to seek and develop new clean energy. As a new type of clean energy, solar energy is a renewable and sustainable energy source. It is rich in resources, does not require transportation, does not pollute the environment, and has incomparable advantages over other resources. [0003] With the development of society, automobiles have become the most common means of transportation, and have gradually become a necessity and have entered the homes of thousands of households. As a result, the energy crisis and environmental pollution have become more serious, and the use of electric vehicles has become inevitable. The solar electric vehicle is directly...

Problems solved by technology

At present, there are many types of solar chargers and inverters, but most of them are used to track and invert the electric energy of solar cells in a static state, or for static charging of small-power handheld devices, etc. The tracking and response speed is slow, and the tracking progress is slow. Low output voltage range, unable to adapt to the rapid change of solar energy caused by shading or angle changes when the vehicle is moving fast The range can reach 30V-96V)

Traditional solar inverters and chargers with higher power are expensive, and the cost of using them in electric vehicles is too high, which reduces the cost performance of the entire vehicle and lowers market competitiveness
