Method and apparatus for determining the state-of-charge of batteries, particularly lithium batteries, involves the steps of: (a) measuring the temperature of the battery; (b) loading the battery to produce a high discharge for a short period of time; (c) after a short rest period, measuring the open-circuit-voltage of the battery; and (d) determining from the measured temperature and open-circuit-voltage the residual state-of-charge of the battery. Preferably, the residual state-of-charge of the battery is determined by comparing the measured temperatur...
The method of determining the state-of-charge of batteries, comprising the steps: (a) measuring the temperature of the battery; (b) loading the battery with a predetermined load to produce a high discharge for a short predetermined time; (c) after a short recovery time, measuring the recovered open-circuit-voltage and the corresponding recovery time of the battery; and (d) determining the state-of-charge of the battery from the measured temperature and measured recovery open-circuit-voltage for the predetermined load and loading time and the recovery tim...
