Abstract: The present invention provides a power storage device capable of preventing rain water, washing water, and the like from entering a casing. The power storage device of the present invention includes a secondary battery, the casing having a sealed structure, a safety valve, and a drainage through hole, the casing includes an external container configured to accommodate the secondary battery and an upper lid disposed above the external container, the upper lid has an upper surface having a concave portion formed therein, the safety valve is disposed in the concave portion, and the drainage through hole is provided to pass through a side wall of the concave portion.

Abstract: The present invention is conceived in such a way as to prevent any damage to the battery management unit even if the solution leaks out of the cell, providing the battery with high safety. The battery according to the present invention is characterized by being provided with a cell, a battery management unit for managing the cell, a protection case holding the battery management unit, and a housing containing the cell and the protection case, wherein the protection case inside is hermetically sealed.

Abstract: The present invention provides a power storage device capable of preventing deterioration of sealability even when a pulling force is applied to a casing and having high safety and excellent durability.

Abstract: In operating to open or close a door (step S1), when an outside switch indicating whether a door knob portion is grabbed or not grabbed by the hand of an operator is brought into an ON state (grip state), or when a distance of moving the door is less than a predetermined angle after bringing the outside switch into an OFF state from the ON state (non-grip state) (step S6), a current threshold higher than a normal current threshold is set (step S3, step S7), a motor current and the current threshold is compared (step S4) and pinching of an obstacle of the door is detected (step S5).
