APPARATUS AND METHODS FOR BATTERY MONITORING USING DISCHARGE PULSE MEASUREMENTS

Methods include determining first and second voltages of a battery before and after a load interval, determining a current through the battery during the load interval, and determining a status of the battery from the determined first and second voltages and the determined current. The load interval may include an interval during which a discharge pulse is applied to the battery, and the first and second voltages may be voltages when the battery is open circuited. The first voltage may be determined before the battery transitions from an open-circuited state to a pulse discharge state, and the second voltage may be determined after the battery transitions from the pulse discharge state to the open-circuited state. Corresponding battery monitoring apparatus and computer program products are also described.
