초록

In the rapid charging of a Nickel Cadmium (NiCad) battery, the rapid charging is terminated and trickle charging is initiated when any of three conditions is satisfied: a first condition determined by comparing a sensed instantaneous battery voltage with a target voltage; a second condition which is determined by comparing the instantaneous battery temperature with minimum and maximum values; and a third condition determined by comparing an elapsed time of rapid charging with a maximum value. Because battery voltage versus rapid charging time is a functi...

청구항

[ What is claimed is:] [1.] A battery charging control device comprising:means for determining a target voltage as a function of a sensed battery temperature or a sensed ambient temperature;means for first comparing a sensed battery voltage with the determined target voltage and based on the result of the first comparing, detecting the occurrence of a first condition;means for terminating the rapid charging in response to the detection of said first condition;means for second comparing a sensed battery temperature with a predetermined maximum temperature...
