Abstract

Disclosed is a method of estimating the state-of-charge of a rechargeable battery, taking into account the factors battery spread and ageing. The method comprises the steps of: determining the starting state-of-charge of the battery by measuring the voltage across the battery and converting this measured value into a state-of-charge value; charging the battery; integrating the charge current and determining the accumulated charge during charging of the battery and adding said value to the starting state-of-charge. Also disclosed is a method for determining the use time left of a rechargeable battery.
