CHARGE CONTROL DEVICE, CELL SYSTEM, AND CHARGE CONTROL METHOD
First Claim
1. A charge control device that controls a charging current to be supplied to a plurality of chargeable and dischargeable cell modules connected in parallel, whereina maximum current value, selected from current values detected by a current sensor provided in each of a plurality of the cell modules, is compared with a reference current value predetermined as a maximum current value of the current to be supplied to the cell modules, and based on a comparison result, the charging current to be supplied to a plurality of the cell modules is controlled.

Abstract
Even when current values of a current that flows to a plurality of cell modules connected in parallel are different, efficient charging is performed. A charge control device that controls a charging current to be supplied to a plurality of cell modules connected in parallel compares a maximum current value, selected from current values detected by a current sensor provided in each of a plurality of the cell modules, with a reference current value predetermined as a maximum current value of the current to be supplied to secondary batteries, and controls the charging current to be supplied to a plurality of the cell modules based on a comparison result.

8. A charge control method for controlling a charging current that is supplied to a plurality of chargeable and dischargeable cell modules connected in parallel, comprising:
-
a first step of comparing a maximum current value, selected from current values detected by a current sensor in each of a plurality of the cell modules, with a reference current value predetermined as a maximum current value of the current to be supplied to the cell modules; and a second step of controlling the charging current to be supplied to a plurality of the cell modules based on a comparison result of the first step.
