Claim 12:
13. A method for controlling charging of a battery pack, the method comprising:
detachably connecting the battery pack to a charger, the battery pack being configured to receive a charging current from the charger connected thereto;
calculating a newest value of a target current value based on (i) a previous value of the target current value and (ii) a maximum variation, the target current value corresponding to a magnitude of the charging current required to charge a cell in the battery pack, the maximum variation corresponding to a characteristic of the battery pack;
notifying the charger of charge condition information including the newest value;
acquiring charging operation information from the charger via communication with the charger, the charging operation information including a charging current value, the charging current value indicating a magnitude of the charging current output from the charger to the battery pack; and
detaching the battery pack from the charger.
