Timing and quantitative charging control system and method for pure electric vehicle

The invention discloses a timing and quantitative charging control system and method for a pure electric vehicle. After charging equipment is plugged into the vehicle, a BCM and a vehicle-mounted charging machine are controlled by a VCU, and charging is started; when charging is conducted on the vehicle, a timing and quantitative charging control module counts time and electricity quantity, when set time or set electricity quantity is reached, the timing and quantitative charging control module transmits a charging ending instruction to the VCU, and the VCU controls the BCM and the vehicle-mounted charging machine to stop the charging process. The timing and quantitative charging control system and method for the pure electric vehicle can set the charging time or charging quantity of the electric vehicle according to practical situations of people to avoid peak electricity usage, and off-peak electricity is used for charging the electric vehicle. The timing and quantitative charging control system and method for the pure electric vehicle can achieve timing and quantitative charging of the vehicle for family charging equipment or pile charging equipment without the help of vehicle external connection appointment equipment, and solve the problems that the pure electric vehicle depends on the vehicle external equipment too much during charging and waste is caused by nonuse of too much remaining electricity quantities of the vehicle.
