A battery pack and a charging method for the same is described. The battery pack includes at least one cell set including multiple cells connected in series. The charging method includes detecting a temperature of the battery pack under a preset state and a voltage of each of the multiple cells, the preset state being a state in which a charging circuit is disconnected and the battery pack is inserted in a charger after the battery pack has been fully charged, calculating a voltage difference between at least two cells in the battery pack based on the voltage of each cell, and determining whether to activate a balancing operation based on the voltage difference and the temperature.
