description The utility model discloses a lithium titanate battery charging and discharging device for a transformer station DC power supply. The lithium titanate battery charging and discharging device comprises a battery pack connected with a DC bus of the transformer station DC power supply. The battery pack comprises a plurality of lithium titanate batteries; each lithium titanate battery is connected with a battery working state acquisition port of the BMS module; the BMS module acquires the SOC value and voltage data of the corresponding lithium titanate battery through each battery working state acquisition port, and sends the acquired data to the direct current monitor; a control circuit is arranged between the positive electrode of the battery pack and the positive electrode of the direct-current bus, and the negative electrode is connected with the negative electrode of the direct-current bus; the control circuit comprises a bypass switch, a contactor and a diode which are connected in parallel; the bypass swit
