| 摘要 |
A remaining battery level of each individual sodium-sulfur battery constituting a plurality of sodium-sulfur batteries is managed, a remaining battery level target value common to all sodium-sulfur batteries is set, and input/output power distributed to each individual sodium-sulfur battery is controlled based on a difference between the target value and the remaining battery level of the sodium-sulfur battery. This enables a uniform remaining battery level among the sodium-sulfur batteries to be attained. |
