Abstract
Determining a state of charge (SOC) of a rechargeable battery includes using a first process to determine a first value for the SOC of the battery and using a second process to determine a second value for the SOC of the battery and deriving the SOC as a weighted average of the first value for the SOC and the second value for the SOC. During a charging cycle of the battery an input charge of the battery is determined from an input current flowing into the battery and a charging time. During a discharging cycle an output charge of the battery is determined from an output current flowing out of the battery, a discharging time and an actual capacity of the battery is the sum of the input charge over charging cycles minus the sum of the output charge over discharging cycles.
