ASSEMBLED BATTERY SYSTEM, STORAGE BATTERY SYSTEM, AND METHOD FOR MONITORING AND CONTROLLING ASSEMBLED BATTERY SYSTEM

摘要

An assembled battery system includes: a control unit having a cell monitoring unit for obtaining battery information by monitoring the battery state of each secondary battery belonging to a storage battery module and a wireless communication unit for, inside a metal chassis housing the storage battery module, wirelessly transmitting the battery information; and a management device for, inside the metal chassis, wirelessly communicating with and managing each of the storage battery modules. The management device transmits to each of the storage battery modules a measurement instruction including information specifying the next measurement timing at predetermined intervals and controls the cell monitoring unit to measure, according to the measurement instruction, the battery states of the storage batteries concurrently among a storage battery modules.
