Charge controlling circuit and method, and electronic device provided with same charge controlling circuit

A charge controlling circuit is provided in which a temperature of a main body of a portable cellular phone (40) or an ambient temperature thereof is detected by a temperature sensor (42) and, when the temperature is higher than or equal to an lower limit in a proper temperature range required by the secondary battery (54) and is lower than a specified reference value, a charging current having a first current value is fed to the secondary battery (54) and, when the temperature is lower than or equal to an upper limit in a proper temperature range required by the secondary battery (54) and is higher than or equal to the specified reference value, a charging current having a second current value being less than the first current value is fed to the secondary battery (54). When the temperature is a value outside of a proper temperature range required by the secondary battery (54), the charging to the secondary battery (54) is stopped.
