  "textContent": "A power storage system has a battery, a three-phase motor in which coils of three phases are connected at a neutral point, an inverter connected on an electric power transmission path between the battery and the three-phase motor, and a DC power supply circuit connected to a connection portion positioned on an electric power transmission path between the inverter and the battery. The battery includes two power storages and a switch unit that switches between a first voltage state where the two power storages are connected in series and chargeable at a first voltage, and a second voltage state where the two power storages are connected in parallel and chargeable at a second voltage. The DC power supply circuit has a branch circuit connected to a coil of any one phase among the coils of three phases at a positive electrode side of the DC power supply circuit.",
