Beschreibung
Zusammenfassung:	The over-discharge optimization circuit comprises a lithium battery assembly, a whole vehicle controller, a whole vehicle intelligent instrument, a whole vehicle low-voltage lighting system, a first DC-DC converter and a two-gear key switch with two-way switch control, and the lithium battery assembly comprises a power source, a BMS battery management system, a second DC-DC converter and a discharge contactor switch. The signal input end of the second DC-DC converter is connected with the power supply, the signal output end of the second DC-DC converter is connected with the signal input end of the BMS battery management system, and the enabling control port C of the second DC-DC converter is connected with the positive electrode of the power supply through the first-gear control switch of the second-gear key switch; the signal output end of the BMS is connected with a coil of the discharging contactor. The problem of lithium battery overdischarge caused by long-time transportation or storage due to the fact
