Charge/discharge control method for rechargeable battery
First Claim
1. A method of controlling charge and discharge of a rechargeable battery constructed as part of a battery pack wherein a plurality of cells, individually constructed as rechargeable batteries, are connected in series, for equalizing the state of charge of each of the cells, characterized in that:
- a charging efficiency of the rechargeable battery corresponding to a target value of SOC is obtained, and the battery pack is charged and discharged repeatedly such that the proportion of a discharging amount relative to a charging amount is equal to the obtained charging efficiency.

Abstract
A battery pack is formed by serially connecting a plurality of cells, that are individually constructed as rechargeable batteries. Charging and discharging of this battery pack are controlled such that, the proportion of discharge current with respect to the charge current equals to a value obtained by multiplying the charge current by a charging efficiency corresponding to a target SOC value.
