Patent number: 11962174Abstract: This application discloses a protection circuit associated with a battery management system (BMS). The protection circuit includes a first protection module and a freewheeling module. The first protection module is connected in parallel to a first switch module of the BMS, and the freewheeling module is connected in parallel to a load module of the BMS. The first protection module switches to a charging state when the first switch module is turned off to stabilize a voltage between a first terminal of the first switch module and a second terminal of the first switch module. The freewheeling module is turned on when the first switch module is turned off to stabilize a voltage between the first switch module and the second switch module. The protection circuit mitigates risks of breakdown of the first switch module, and prevents a parasitic inductance from limiting a switching frequency of the first switch module.Type: GrantFiled: December 15, 2020Date of Patent: April 16, 2024Assignee: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Wei Zhang, Zhimin Dan, Jinbo Cai, Yizhen Hou, Meilin Chen
