초록 ▼

A rechargeable battery charging circuit comprises a detection circuit for detecting the ambient temperature and a charging current control circuit for controlling the charging current in dependence upon the ambient temperature. The battery charging circuit charges the battery in response to the ambient temperature variations in order to maximize the charging efficiency of the battery at temperatures higher than room temperature.

대표청구항 ▼

[ What is claimed is:] [1.] A battery charging circuit for charging a rechargeable battery, comprising:first means for supplying a variable amount of charging current to said battery in response to a first control logic signal;second means for controlling the amount of the charging current in response to a second control logic signal;third means for detecting a temperature of said battery and generating a first detection signal having a magnitude which varies substantially linearly with the battery temperature;fourth means for generating the first and second control logic signals in dependence upon the magnitude of the first detection signal;fifth means for detecting an ambient temperature of said battery and generating at least two second detection signals corresponding to at least two predetermined ambient temperature ranges respectively; andsixth means for controlling the amount of the charging current in response to the second detection signals.
