Application: Storage battery system (Patent ID: US20230420756A1)
The patent filed by Toshiba Corp. describes a battery system that includes storage battery modules with wireless communication capabilities based on the BLE standard. Each storage battery module consists of an assembled battery, a first wireless communication module, and a battery monitoring unit. The system also includes a battery management unit with multiple second wireless communication modules and an arithmetic processing device. The first wireless communication module is pre-set with a first identifier, and when a connection is initiated, the module with a matching second identifier from an advertising packet becomes a broadcaster and transmits the packet.
Claim 1 of the patent outlines the structure of the battery system, detailing the components of the storage battery modules and the battery management unit. It specifies the functionality of the first and second wireless communication modules in establishing connections and transmitting data based on identifiers. Claim 2 further elaborates on the behavior of the wireless communication modules, indicating that the first module can broadcast regardless of the identifier value under certain conditions. Additionally, it describes how the second wireless communication module can request a change in the identifier of the first module for communication purposes. Overall, the patent focuses on a system that enables efficient wireless communication and monitoring within a battery system.
