Pure electric vehicle power supply life-prolonging rapid charging method and control system thereof

A pure electric vehicle power supply life-prolonging rapid charging method and a control system thereof. The control system comprises a charging device, a battery module, a controller, a running display and alarm device, a motor, and a motor driver; the charging device is connected with the battery module; the battery module is connected with the controller and the motor driver; the controller isconnected with the running display and alarm device; the motor driver is connected with the motor. According to the charging method, a full charge is reached when charging is performed with a 0.5 C current for 120 min or when a voltage reaches an upper limit of n*1.45 V; when a vehicle runs 110 km or the voltage reaches n*1.23 V, a program-controlled alarm is provided and pre-charge is prompted; rapid charging of the vehicle is performed; a full charge is reached when charging is performed with a 1.5 C-2 C current for 10 min or when the voltage reaches an upper limit of n*1.50 V. The method has the advantages of high
