[Abstract]:Aiming at the problems of long charging time, high voltage fluctuation and low speed of MPPTs in the application of photovoltaic power generation system in electric vehicle, a solar charging system in vehicle environment is studied and designed. Based on the conductance increment method, a modified variable step increment MPPT method is proposed for vehicle operation. The Boost circuit which realizes MPPT control in charging system and the Buck circuit and Pi controller used for charging control are modeled and analyzed. Based on the PSIM simulation platform, the fast tracking performance of the proposed MPPT method is verified, and the charging system has the advantages of low voltage perturbation and high steady-state accuracy, and through the comparison of charging experiments with or without the MPPT function, it shows that the system also has the advantages of short charging time and high efficiency.
