Title:
POWER BATTERY MODULE EQUALIZATION SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/197813
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the field of battery equalization design, and disclose a power battery module equalization system and a control method therefor. The system comprises a mains electricity conversion module, a strong electricity management module, an output module, a battery module, an electronic load, a power transfer module, a sampling module, and a microcontroller unit. According to the system, when the sampling module acquires that a voltage difference between power batteries in the battery module is relatively large, the electronic load and/or the power transfer module can be connected to the battery module to realize equalization, and when the voltage difference between the power batteries is relatively small, the output power is adjusted by adjusting the on-off of a switching tube in the strong electricity management module for quick charging. Therefore, the system is simple in structure and easy to control.
