Abstract: The charging algorithm is particularly important for the improvement of charging effect of electric vehicles. In this paper, the traditional constant current and constant voltage charging algorithm is analyzed, studied and simulated, and a variable pulse charging algorithm is proposed. By studying the variation law of battery voltage and current in the charging process of various algorithms, tak-ing the charging time and temperature rise as the measurement index, it is compared with constant current charging algorithm, constant voltage charging algorithm and fixed pulse charging algorithm. The simulation results show that the variable pulse charging algorithm has better charging effect than other charging algorithms.
