Vehicle-mounted photovoltaic charging system of electric vehicle

Abstract

The invention discloses a vehicle-mounted photovoltaic charging system of an electric vehicle. The system comprises a solar cell panel, an inverter, a storage battery pack, a charging control circuit,a PC terminal and a control module. The solar cell panel, the inverter, the storage battery, the charging control circuit and the PC terminal are connected with the control module. The solar cell panel converts light energy into electric energy and stores the electric energy in the storage battery pack. The control module comprises an MPPT module and an STM32 control unit, the MPPT module is usedfor tracking the maximum power point of the solar cell panel, and the STM32 control unit controls the duty ratio of a DC-CD circuit in the MPPT module through a timer; and the STM32 control unit is used for uploading the data to the PC terminal. By means of the mode, the vehicle-mounted photovoltaic charging system of the electric vehicle can supplement electric quantity for a power source of theelectric vehicle in time, is not limited by the position of a charging station to improve the driving range of the electric vehicle.

[0002] With the rapid development of science and technology in the 21st century, the ideas of sustainable development, energy conservation and environmental protection have been implemented in every corner of people's lives. With the emergence of electric vehicle technology, the application of solar photovoltaic power generation technology in automobiles may be possible. Photovoltaic power generation The wide application of electric vehicles in the system can reduce the power consumption of electric vehicles' power batteries, increase the cruising range of electric vehicles, and provide a way to solve the bottleneck problem of cruising range of electric vehicles, although the efficiency of electric vehicles is much lower than that of traditional fuel Great advantages, but there are also many disadvantages. If the driving range is short and the experience is poor, the power battery is easily affected by external factors.
