PCT No. PCT/SE91/00368 Sec. 371 Date Nov. 30, 1992 Sec. 102(e) Date Nov. 30, 1992 PCT Filed May 24, 1991 PCT Pub. No. WO91/19343 PCT Pub. Date Dec. 12, 1991.A method of regulating the charging of batteries containing a number of cells, for example NiCd cells. The battery is connected to a battery charger for impressing a current through the battery for charging thereof. Prior to the actual impression of current through the battery cells for raising their terminal voltage, the voltage drop caused by cables, connections, the inner resistances of the battery caused by the battery cells, etc., is established for a number of different brief current pulses. The value of the voltage drop established for each current pulse is stored in a memory, and currents of substantially the same magnitude as each respective current pulse are impressed successively through the battery, each one of a length of time such that the voltage measured across the battery corresponds to the maximum permitted terminal voltage of the battery, plus the voltage drop established and stored for the corresponding current pulse. |
