CHARGING METHOD USING ELECTRIC VEHICLE CHARGING STATION CONTROL UNIT Russian patent published in 2024 - IPC B60L53/60 

FIELD: electrical charging.

SUBSTANCE: invention relates to charging method via the electric vehicle charging station control unit. The method includes slow AC charging and fast DC charging. AC/DC charging is switched in the AC charging control connector. Information exchange between the charging station controller and the electric vehicle is carried out using a PWM signal. The duty cycle sets the maximum allowed charging current for the electric vehicle. The charging current is set to no more than the maximum allowed by the charging station. By measuring the voltage, the charging station determines that the cable assembly is connected to the electric vehicle and is ready for charging. When connecting the cable assembly, the voltage through the resistor drops to the limit value. When ready to charge, the electric vehicle closes the switch and the voltage drops to a critical value. After detecting a critical value and permission from the server, the controller closes the contactor and the current supply process begins. When charging with direct current, the energy supply process is completely controlled by the charging station. The controller transmits commands to the AC/DC converter so that it, in turn, sets the required voltage and current.

EFFECT: possibilities for using the charging station control unit for electric vehicles are expanded.
