Title:
SWITCH CONTROL DEVICE AND METHOD, MOTOR CONTROLLER, AND BATTERY PACK HEATING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/259104
Kind Code:
A1
Abstract:
The present application discloses a switch control device and method, a motor controller, and a battery pack heating control system, which relate to the field of battery power. The switch control device comprises: a processing module configured to, if it is determined that a switch control period is switched to the current period from a previous period, select a target upper bridge arm switch module of the current period from other upper bridge arm switch modules of three-phase bridge arms except for a target upper bridge arm switch module of the previous period, and/or select a target lower bridge arm switch module of the current period from other lower bridge arm switch modules of the three-phase bridge arms except for a target lower bridge arm switch module of the previous period. The processing module is further configured to control, in each switch control period, the turning on and turning off of the target upper bridge arm switch module and the target lower bridge arm switch module. The switch control device and method, the motor controller, and the battery pack heating control system provided in the embodiments of the present application can improve the safety of the heating of the battery pack.
