Vehicle-mounted charging control system of electric vehicle and control method thereof

Abstract

The invention discloses a vehicle-mounted charging control system of an electric vehicle and a control method of the system. The system comprises a charger controller, a local charging management system, a storage battery and a remote service center. The charger controller is used for receiving and processing information sent by the charging management system and charging the storage battery. The local charging management system is used for receiving a real-time charging strategy of the remote service center and carrying out all-round tracking and information feedback during the charging process. The storage battery is used for feeding back voltage and charging or discharging through bilateral communication of the storage battery and the charging management system. The remote service center is used for diagnosing the charging process in real time, providing the optimal charging control strategy suitable for a battery arranged on each electric vehicle, accumulating charging times and charging stability, and reminding a vehicle owner to go to a maintenance station timely when problems occur. The charging process is safe and controllable, resistance from the society to high-voltage electricity during use of the electric vehicle is eliminated, real-time tracking and remote diagnosis of charging parameters of the electric vehicle are achieved, and charging reliability of the electric vehicle is improved.

Description

technical field [0001] The invention relates to a vehicle-mounted charging control system for an electric vehicle and a control method thereof. Background technique [0002] With the implementation of energy-saving and environmental protection policies, the state has given greater support to the development of pure electric vehicles, which have less impact on the environment than traditional vehicles, and their development prospects are promising. But with the popularity of electric vehicles, safety and quality issues have also come one after another. It is mainly reflected in the safety and reliability of the electric vehicle charging process. Compared with the development of electric vehicle body, driving motor, control technology, etc., the charging and discharging technology of electric vehicle battery is still very backward. People are still working hard on the development of new high-performance batteries and optimizing intelligent charging methods. . [0003] In or...
