Abstract
An off prevention circuit has a battery management system and a contactor multi-connected via a plurality of positive electrode terminals and a plurality of negative electrode terminals provided in each of the battery management system and the contactor. Even when any one connection among the connections of the plurality of positive electrode terminals and the plurality of negative electrode terminals is disconnected or opened, it is possible to maintain supply ofpower supplied from the battery management system to the, contactor through another connection of the positive electrode terminal and the negative electrode terminal.
Claims5
An off-prevention circuit, the circuit comprising:
- a battery management system (BMS) which controls power supplied to a contactor, and includes a first BMS positive electrode terminal and a second BMS positive electrode terminal for connection to a positive electrode of a power supply and a first BMS negative electrode terminal and a second BMS negative electrode terminal for connection to a ground or a negative electrode of the power supply,
- wherein the contactor makes an on/off connection between a battery pack and a load, the contactor including a first contactor positive terminal connected to the first BMS positive electrode terminal and a second contactor positive electrode terminal connected to the second BMS positive electrode terminal, and a first contactor negative electrode terminal connected to the first BMS negative electrode terminal and a second contactor negative electrode terminal connected to the second BMS negative electrode terminal.
