Abstract (en)
[origin: WO9703489A1] A method and an apparatus for adjusting the process of charging a battery so as to charge the battery as rapidly as possible while avoiding overheating of or damage to the battery. The method provides for applying a charging pulse (C1) which provides an average charging current, applying a first depolarizing pulse (D1), waiting for a first rest period (DW1), measuring the voltage (V1) at a predetermined point within the first rest period, applying a second depolarizing pulse (D2), waiting for a second rest period (DW2), measuring the voltage (V2) at the predetermined point within the second rest period, determining a difference between the voltage (V1) and the voltage (V2), and decreasing the average charging current if the difference is greater than a predetermined amount. The present invention also provides for determining whether the battery is low on water.
