A battery pack includes a battery cell, a charge calculator that calculates an amount of charge of the battery cell, a charge setting that sets multiple amounts of charge with different upper limits, a charge selecting switch that selects one of the amounts of charge, and a battery controller having a communication function that sends, to the charging apparatus, charge information about the battery cell and charging command information that instructs charging to be continued to an upper limit for the selected amount of charge. |
