Title:
CONTROL SYSTEM AND METHOD FOR BATTERY PACK HEATING SYSTEM, AND BATTERY PACK HEATING MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/259103
Kind Code:
A1
Abstract:
A control system and method for a battery pack heating system, and a battery pack heating management system, relating to the field of battery power. The control system (P4) for the battery pack heating system comprises: a battery management system (P41), configured to obtain a state parameter of a battery pack (P1), and send, if it is determined that the state parameter of the battery pack (P1) satisfies a preset heating condition, heating request information to a vehicle controller (P43); a motor controller (P42), configured to send, if it is determined that a motor (P3) of the battery pack heating system is in a non-operating state, to the vehicle controller (P43) feedback information that the motor (P3) is in a non-operating state, and configured to control, in response to a first control signal, target upper bridge arm switch modules (P21, P23, P25) and target lower bridge arm switch modules (P22, P24, P26) to be turned on periodically to heat the battery pack (P1); and the vehicle controller (P43), configured to send, in response to the heating request information and the feedback information, the first control signal to the motor controller (P42). The present solution can improve the control precision for the battery pack heating system.
