Abstract:
A method of determining the state of charge (SOC) of a rechargeable battery, the method comprising charging the battery using a substantially constant charge current; measuring the battery temperature; and conducting a first measurement of the battery voltage at a time interval, t1, from the start of the charging, and a second measurement of the battery voltage at a time interval, t2, from the first measurement.
