Abstract
Remaining capacity calculation section (110) calculates the remaining capacity for each of cells (300-1) and (300-2) connected in parallel with each other, and control section (130) stops discharge of the first cell from cells (300-1) and (300-2), whose remaining capacity calculated by remaining capacity calculation section (110), has become equal to a threshold value stored in storage section (120) after the start of discharge of cells (300-1) and (300-2).
Claims9
A discharge controller for controlling discharge of a plurality of cells connected in parallel with each other, the controller comprising:
- a remaining capacity calculation section that calculates a remaining capacity for each of the plurality of cells;
- and
- a control section that, after starting discharge of the plurality of cells, compares the remaining capacities calculated by said remaining capacity calculation section with a threshold value set in advance, and stops discharge of the first cell whose remaining capacity has become equal to the threshold value, and continues discharge of the other cells whose remaining capacity has become equal to the threshold value.
A discharge control method of controlling discharge of a plurality of cells connected in parallel with each other, the method comprising:
- discharging the plurality of cells;
- calculating a remaining capacity for each of the plurality of cells;
- comparing the calculated remaining capacities with a threshold value set in advance, after starting discharge of the plurality of cells;
- stopping, as a result of the comparison, discharge of the first cell whose remaining capacity has become equal to the threshold value;
- and
- continuing, as a result of the comparison, discharge of the other cells whose remaining capacity has become equal to the threshold value.
