Publication number: 20230387696Abstract: A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.Type: ApplicationFiled: May 26, 2023Publication date: November 30, 2023Inventors: Jianfei Liu, Jujie Xia, Youwu Chen, Huizhi Chen, Wenhua Li, Ke Yan, Changda Guan, Zibin Cheng, William Tenorio, Daniel Kang, Chris Turner

Patent number: 11476677Abstract: Systems and methods are described for managing charging and discharging of battery packs. In one or more aspects, a system and method are provided to minimize overcharging of battery cells of specific battery chemistries while still enabling fast charging cycles. In other aspects, a buck converter may be used to reduce a voltage of power used to charge the cells. In further aspects, a fast overcurrent protection circuit is described to address situations involving internal short circuits of a battery cell or battery pack. In yet further aspects, a bypass circuit is provided in series-connected battery packs to improve the charging of undercharged battery packs while also increasing the efficiency of the overall charging process. In other aspects, a circuit is provided that permits a controller to determine a configuration of battery packs.Type: GrantFiled: March 30, 2022Date of Patent: October 18, 2022Assignee: Inventus Power, Inc.Inventors: Jianfei Liu, Wenhua Li, Ke Yan, Huizhi Chen
