Title:
ELECTRIC VEHICLE CHARGING POWER SUPPLY AND CHARGING MANAGEMENT SYSTEM, CHARGING PILE, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/098527
Kind Code:
A1
Abstract:
Provided herein are an electric vehicle charging power supply and charging management system, a charging pile, and an electric vehicle. The charging power supply comprises a communication module, a parameter acquisition module, and a master control module. The communication module is communicatively connected to an external control unit. The external control unit is a controller in the charging pile or the electric vehicle charging management system. The parameter acquisition module is used for acquiring a current, a voltage, and a temperature parameter of the charging power supply in real time. The master control module is communicatively connected to the parameter acquisition module and the communication module, separately, and is used for controlling, according to the current, the voltage, and the temperature parameter of the charging power supply, and a control signal of the external control unit transmitted by the communication module, the charging power supply to charge a vehicle-mounted battery in a constant current mode or a constant voltage mode. The charging power supply herein comprises a master control module, and the external control unit only needs to provide charging requirements and start-stop signals, so that the master control module can charge in a constant current mode or a constant voltage mode, and a corresponding function does not need to be achieved by an external charging system.
