Patent attributes
In a battery monitoring system including a plurality of battery modules each including one or more cells, the battery modules are connected in series to each other. The battery monitoring system monitors the state of each cell based on the voltage value of the cell and the current value of the battery modules. A current detection unit detects the current value. Each voltage detection unit is associated with the corresponding one of the battery modules and detects the voltage value. Each slave unit is associated with the corresponding one of the battery modules, and wirelessly transmits information including synchronous current and voltage values detected by the current detection unit and the voltage detection unit. A master unit receives the information transmitted from the slave units. A central monitoring unit receives the information received by the master unit.
