Abstract:
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 and based on the result of the second comparing, detecting the occurrence of a second condition; wherein said terminating means is for terminating the rapid charging in response to the detection of occurrence of any of the first and said second conditions; andmeans for third comparing a sensed battery temperature with a predetermined minimum temperature and based on the result of the third comparing, detecting the occurrence of a third condition; wherein said terminating means is for terminating the rapid charging in response to the detection of occurrence of any of the first, second, and third conditions.
