An electric power storage system according to the invention includes an electric power storage device, a converter performing voltage conversion between the electric power storage device and a traveling motor, a DC/DC converter disposed on a current path between the electric power storage device and the converter and stepping down an output voltage to an auxiliary machine and/or an auxiliary machine battery, a charger, a first relay disposed on a first connection line as one of positive and negative electrodes connecting the electric power storage device to the converter, and a second relay disposed on a second connection line as the other one of the positive and negative electrodes connecting the electric power storage device to the converter. One end of the DC/DC converter is connected to the first connection line between the first relay and the converter and the other end of the DC/DC converter is connected to the second connection line between the electric power storage device and the second relay. The charger is disposed on a current path capable of charging the electric power storage device with external electric power when the first relay is in an ON state and the second relay is in an OFF state.
