CONTROL SYSTEM AND METHOD FOR BATTERY PACK HEATING SYSTEM AND BATTERY PACK HEATING MANAGEMENT SYSTEM

The disclosure provides a control system (P4) and method (300) for a battery pack heating system, and a battery pack heating management system, and is related to the field of battery power. The control system (P4) for the battery pack heating system includes: a battery management system (P41) configured to acquire a state parameter of a battery pack (PI), and send heating request information to a vehicle controller (P43) when it is determined that the state parameter of the battery pack (P1) meets a preset heating condition; a motor controller (P42) configured to send, to the vehicle controller (P43), feedback information indicating that a motor (P3) of the battery pack heating system is in a non-operating state, when it is determined that the motor (P3) is in the non-operating state, and control, in response to a first control signal, a target upper bridge arm switch module and a target lower bridge arm switch module to be periodically turned on or off, so as to heat the battery pack (PI); and the vehicle controller (P43) configured to send the first control signal to the motor controller (P42) in response to the heating request information and the feedback information. The solutions provided in the disclosure can improve the control accuracy for the battery pack heating system. [Fig. 2]
