A power storage system having a power storage device (10) configured to be charged and discharged, a boost circuit (33) and a controller (40), and a method of controlling the temperature of the power storage device (10) are provided. The boost circuit (33) includes a reactor (33a) and switching devices (33d, 33e), and boosts the output voltage of the power storage device (10) when the switching devices (33d, 33e) are driven. The controller (40) alternately performs a charging operation to supply electric power from an external power supply (54) to the power storage device (10), and a temperature elevating operation to warm up the power storage device (10), using ripple current generated when the switching devices (33d, 33e) are driven. |
