BATTERY CHARGING STATION Russian patent published in 2023 - IPC H02J7/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to devices for charging batteries. The battery charging station contains inputs for connecting to a power source, equipped with circuits for the main and preliminary charging of the battery, a current conversion circuit, terminals for connecting to the battery terminals, an input for receiving signals from the battery controller and a charge prohibition circuit connected to this input and to the current conversion circuit. The battery precharge circuit consists of a current limiting resistor, a precharge contactor, and a precharge contactor closure circuit connected to the precharge contactor and to the input to receive signals from the battery controller. The main charge circuit consists of a main contactor and a main contactor closing circuit connected to the main contactor and to the input to receive signals from the battery controller. In this case, the pre-charge contactor closure circuit is connected to the main contactor closure circuit and is configured to send a signal to it about the closure of the battery precharge contactor, and the main contactor closure circuit is connected to the charge prohibition circuit and is configured to send a signal to it about the main closure contactor.

EFFECT: reducing the risk of failure of the elements of the battery charging station.
