Abstract
A higher-level controller is configured to execute a first process of setting an adjusting value for adjusting a target value that is set by a plurality of lower-level controllers of a plurality of battery modules. The lower-level controllers are configured to execute a second process of updating the respective target values that are set by the respective lower-level controllers.
Claims4
A power supply device comprising:
- a plurality of battery modules connected in series;
- and
- a higher-level controller, wherein:
- each of the plurality of battery modules includes:
- a plurality of battery cells connected in series;
- a detection unit detecting respective remaining capacities of the plurality of battery cells;
- a lower-level controller configured to execute a process of setting a target value for equalizing the remaining capacities of the plurality of battery cells based on the remaining capacities of the plurality of battery cells that are detected by the detection unit;
- and
- an equalization processor for equalizing the remaining capacities of the plurality of battery cells according to the target value set by the lower-level controller, wherein:
- the higher-level controller is configured to execute a first process of setting an adjusting value for adjusting the target value set by the lower-level controller of each of the plurality of battery modules;
- and
- the lower-level controllers of the plurality of battery modules are configured to execute a second process of updating the target value set respectively by the lower-level controllers.
