Research on energy autonomy system design of field patrol car based on solar energy

The Inner Mongolia Autonomous Region has abundant solar energy and electric power resources. Due to the long distance between cities, the transmission lines are too long, which leads to difficulties in line inspection. To overcome the problem of line inspection, a field patrol car using solar energy is studied in this paper, the energy system of which can complete the charge and discharge independently and then realize the inspection task.Revolving around the energy autonomy of solar-energy field inspection vehicle, this paper first selects the appropriate components and builds the energy-autonomy inspection system of the patrol car, according to its design requirements. Then the solar tracking algorithm and MPPT control algorithm are used to improve the conversion rate of solar panels, so that the fast charging can be realized. Finally, the hardware and software of the solar controller are designed, and the corresponding functions are debugged.
