A control system and method for timing and quantitative charging of pure electric vehicles

Abstract

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.

Description

technical field [0001] The invention belongs to the field of pure electric vehicle power systems and relates to battery charging technology for pure electric vehicles. Background technique [0002] In modern society, the automobile industry develops rapidly. Cars have changed people's lives and made people's travel more convenient and faster. At the same time, problems such as energy shortage and environmental pollution caused by traditional vehicles are becoming more and more obvious. At this time, pure electric vehicles are gradually accepted by people. The characteristics of zero emission and the ability to use multiple energy sources as power sources of pure electric vehicles can greatly improve the energy and environmental problems caused by traditional vehicles. At present, the development of electric vehicles has been strongly supported by the governments of various countries, and has become the development trend of the automobile industry. The research and developm...
