US 2006/0152196 A1 · Method of controlling battery current limiting

Abstract

The method of controlling battery current limiting controls maximum charging and discharging current values according to the state of charge of the battery. The method of controlling current limiting integrates battery charging and discharging current to compute a first state of charge, determines first charging and discharging current limit value candidates from that first state of charge, computes a second state of charge based on battery voltage, and determines second charging and discharging current limit value candidates from that second state of charge. Further, the method takes the smaller of the first and second charging and discharging current limit value candidates as the charging and discharging current limit values for charging and discharging the battery.
