Problems solved by technology
[0003] However, for scenarios where external auxiliary power cannot be provided, such as mobile charging treasures, mobile energy storage vehicles, mobile energy storage cabinets, etc., there are two common practices in the industry. One is to use an external independent auxiliary power supply, such as Lead-acid battery packs provide auxiliary power as the BMS power supply, and the other is the long-term high-voltage to low-voltage auxiliary power standby in the battery, which increases the complexity and cost of the actual product application, increases energy consumption, and reduces the actual product. application reliability

The invention discloses an awakening system for a high-voltage power battery pack application system. The awakening system comprises a high-voltage power battery pack group and a system power supply conversion system, wherein the system power supply conversion system comprises a system main control unit, a communication circuit and a main power module; positive electrode output and negative electrode output of the high-voltage battery pack group are separately connected to two input ends of the main power module; the high-voltage battery pack group comprises a first high-voltage battery pack;the first high-voltage battery pack comprises a battery group, a battery pack BMS, a controllable switch and a high-voltage output hole HVDC, the high-voltage output hole HVDC is used for power output, the high-voltage output hole HVDC is separately connected to a negative electrode of the battery group and one end of the controllable switch, a positive electrode of the battery group is connectedto the other end of the controllable switch, the battery pack BMS is electrically connected to the control end of the controllable switch, and the battery pack BMS is used for controlling disconnecting or connecting of the controllable switch. The awakening system for the high-voltage power battery pack application system can safely, reliably and efficiently apply energy stored in the high-voltagepower battery pack.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a wake-up system for a high-voltage power battery pack application system. Background technique [0002] With the rapid development of new energy electric vehicles and the vigorous promotion of power battery applications, household energy storage, mobile energy storage charging, etc. The manual operation is closed and disconnected, and the high-voltage battery pack is usually powered by an external auxiliary power supply to activate and wake up the BMS control circuit in the battery pack. [0003] However, for scenarios where external auxiliary power cannot be provided, such as mobile charging treasures, mobile energy storage vehicles, mobile energy storage cabinets, etc., there are two common practices in the industry. One is to use an external independent auxiliary power supply, such as Lead-acid battery packs provide auxiliary power as the BMS power supply, and the other is...
