Abstract
A battery system is provided with a plurality of battery units each including a battery module consisting of a plurality of battery cells, a unit control unit, and a connector, and controls the overall operation of the respective battery units in a main control unit. To the plurality of connectors of the battery units, an external unit can be selectively connected so that voltage adjustment for inhibiting voltage variations among the plurality of battery cells or the plurality of battery modules can be realized by using the external unit. The external unit is connected to the battery unit for which voltage adjustment is necessary on the basis of a voltage adjustment necessity determination.
Claims9
A battery system comprising:
- a plurality of battery units each having a battery module consisting of a plurality of battery cells and a connector that is connected to the battery module and that can be connected to an external unit having a function to execute a voltage adjustment;
- and
- a voltage adjustment necessity determination unit that determines, for each battery unit, whether or not the voltage adjustment for inhibiting a voltage variation among the battery modules or the battery cells is necessary, wherein
- based on a result of determination of the voltage adjustment necessity determination unit, connection of the external unit to a battery unit for which the voltage adjustment is necessary is permitted or the external unit is connected to the battery unit for which the voltage adjustment is necessary, and
- in each battery unit, the voltage adjustment is enabled when the external unit is connected to the connector.
