Abstract
When the number of battery cells of a certain battery block is different from a reference number of cells, the inter-terminal voltage of the battery block is converted into the voltage corresponding to the reference number of cells. Thus, even when a plurality of battery blocks being different in the number of battery cells are included, a map for calculating the SOC may only be one. That is, since conventional software or calculation methods can be used, it is not necessary to increase the capacity of SOC calculation software or allowable battery output calculation software. As a result, a plurality of assembled batteries being different in the number of battery cells constituting each battery block can appropriately be monitored.
