STORAGE BATTERY DEVICE, STORAGE BATTERY CONTROL DEVICE, AND STORAGE BATTERY CONTROL METHOD

摘要

A plurality of storage batteries (10) are connected in series to each other. A current adjusting unit (20) is provided corresponding to at least one storage battery (10). The current adjusting unit (20) is provided in parallel with the storage battery (10), and controls the amount of current passing through the storage battery (10). An internal resistance measuring unit (30) measures the internal resistance of the storage battery (10) where the current adjusting unit (20) is provided. A control unit (40) controls the current adjusting unit (20) on the basis of the measurement result of the internal resistance measuring unit (30).
