Beschreibung
Zusammenfassung:	The utility model provides a battery management system which comprises a current limiting circuit with a first controllable switch and a current limiting resistor, a main circuit with a second controllable switch and a battery management system control unit, and the current limiting circuit and the main circuit are connected in parallel and jointly connected between a battery pack and a load in series. And the battery management system control unit is connected with the first controllable switch and the second controllable switch. According to the battery management system, the current limiting circuit which is connected with the main circuit in parallel and is provided with the current limiting resistor is additionally arranged, so that when the battery management system is in the sleep mode, the first controllable switch is controlled to be switched on, and the second controllable switch is controlled to be switched off, so that the battery pack supplies power to the load based on the current limiting circu
