摘要： A first projecting portion is disposed between a head portion of an external terminal and a gasket body of a gasket, the first projecting portion projecting toward the gasket body from a first opposedly-facing surface which opposedly faces a case of the head portion, the first projecting portion surrounding the shaft portion, the first projecting portion having a pressing surface which directly or indirectly presses the gasket body in a projecting direction of the first projecting portion. The gasket has the second and third opposedly-facing surfaces, the second opposedly-facing surface opposedly facing the head portion, the third opposedly-facing surface opposedly facing the case. A second projecting portion is disposed in a region of at least one of the second and third opposedly-facing surfaces which correspond to the first projecting portion, the second projecting portion surrounding the shaft portion and being in a state where the second projecting portion is compressed toward the second or third opposedly-facing surface by the pressing surface.

摘要： An energy storage system includes a lead-acid battery, a battery management unit. The battery management unit defines, based on an open voltage of the lead-acid battery, a first amount of change in a capacity of the lead-acid battery from a reference state, correlating with the open voltage of the lead-acid battery and caused by a first deterioration factor and defines, based on the first amount of change in the capacity and an amount of change in overall internal resistance of the lead-acid battery from the reference state, a second amount of change in a capacity of the lead-acid battery, not correlating with the open voltage and caused by a second deterioration factor. The battery management unit defines, based on the first and second amounts of change in the capacity, at least one of a battery capacity of the lead-acid battery or an amount of change in the battery capacity from the reference state.

摘要： A deterioration amount estimation device includes a calculation unit (CPU33) that calculates a deterioration amount of an energy storage device and an estimation unit (CPU33) that estimates a transient deterioration amount based on a deterioration amount calculated by the calculation unit and a continuous deterioration amount that does not decrease with time and continues. The transient deterioration amount is estimated, and the input/output of the energy storage device is limited to suppress an increase in the continuous deterioration amount.
