Abstract:
PCT No. PCT/JP94/00651 Sec. 371 Date May 24, 1995 Sec. 102(e) Date May 24, 1995 PCT Filed Apr. 20, 1994 PCT Pub. No. WO95/09471 PCT Pub. Date Apr. 6, 1995To provide a single universal charging apparatus, capable of charging at high speed and efficiency any type of secondary battery, and capable of charging secondary batteries any arbitrary charging rate. In selecting the arbitrary amount of current from low current to high current while charging a variety of secondary batteries, the voltage and temperature of the battery are monitored, so that either at the point at which the rate of rise of the temperature of the battery exhibits an increase over the immediately previous rate of rise that exceeds a given reference value, or at the point at which the difference in change of battery voltage is decreased continuously for a preestablished amount of time, the charging of the battery is stopped.
