[0002] The battery management system (BMS) serves as the link between the battery and the user, primarily targeting secondary batteries. Its primary purpose is to improve battery utilization and prevent overcharging and over-discharging. Patent publication number CN207916614U describes an integrated BMS connector for electric vehicle battery packs. This connector, formed through a wiring harness interface to prevent wiring entanglement, combines different commercially available BMS test harnesses into an integrated harness. This helps improve harness utilization for BMS material collection, sample preparation, and anomaly detection, avoiding the need for repeated production when battery factories use different BMS harnesses, saving time and money. Furthermore, the test equipment wiring in the communication adapter can be directly connected to the corresponding test cable, making it convenient and quick.
