An ECU executes a program including the steps of causing a battery pack to discharge (S110, 120) when an external power supply is connected to a charger (YES at S100), stopping discharge of the battery pack (S116, S126) when a state of charge of the battery pack is reduced to a reset value (YES at S114, YES at S124), and charging the battery pack after the state of charge is reduced to the reset value (S130). |
