Abstract: PURPOSE: To obtain a charger and a charging method for a secondary battery, e.g. a lithium ion battery, in which an AD port is not required at a charge control section for detecting full charging. CONSTITUTION: The charger comprises a connection switching means Q2 for a power supply section 4, means 2a, 2b, 2c for detecting the terminal voltage V1 of a secondary battery E, a voltage drop representative of charging current, and a reference voltage Vref, respectively, means CP1 or CP2 for comparing the voltages detected by the voltage detecting means 2a or 2b with the reference voltage Vref, and a charging control section 1 having two ports P1, P2 for receiving outputs from the comparing means and a port P3 for controlling the switching means Q2. A charging current I1 is compared with the reference voltage Vref by the comparing means CP2 and if it is lower than a predetermined level, the switching means Q2 disconnects the power supply section 4 for a predetermined time. Voltage V1 of the secondary battery E is then detected and compared with the reference voltage Vref by the comparing means CP1 and a decision is made that the battery is fully charged if the voltage V1 is higher than a predetermined level.
