Abstract: An energy storage apparatus for engine start-up includes: an energy storage device, a first switch provided in a first energizing path to the energy storage device, a step-down circuit provided in a second energizing path to the energy storage device, and a controller. The controller turns the first switch on to discharge through the first energizing path at engine start-up, and turns the first switch off to select the second energizing path if an output voltage of a vehicle generator is higher than a predetermined voltage to cause the output voltage of the vehicle generator to be stepped down with the step-down circuit to charge the energy storage device.

Abstract: An object of the invention is to provide a lid for storage battery, an injection molding method of the lid, a storage battery with the lid, and a terminal section for storage battery, which can save trouble of inserting a nut into a cavity portion of a terminal, and can prevent falling of the nut at the time of connection of an external leading wire. In a lid for storage battery in which a terminal section for storage battery 8 made up of a terminal 4 having a cavity portion, a bushing 6, and a conductive portion 7 joining both is insert-molded in a lid made of synthetic resin, and a storage battery with the lid for storage battery, an anchor portion 4T is projected at a location excluding at least a central portion of a bottom portion 4F of the terminal 4, and a nut is inserted into the cavity portion of the terminal to be fixed. Moreover, in the terminal section for storage battery, the anchor portion 4T is projected at the location excluding at least the central portion of the bottom portion 4F of the terminal 4 (e.g., the U-shaped anchor portion 4T is projected with a U-shaped joining portion 4G interposed).

Abstract: A power storage module is formed by superimposing a pair of end plates at opposite ends in the stacking direction of a plurality of power storage cells that are stacked in the stacking direction. The pair of end plates are connected by a frame holding an insulator between itself and the power storage cells. Condensed water occurring on the surface of the power storage cells could contact the end plate. There is thus a possibility that a liquid junction will be formed; when the power storage module is in a mounted state the insulator includes a first rib extending in a direction, condensed water attached to the insulator cannot flow toward the end plate due to it being blocked by the first rib, thus preventing the power storage cell from forming a liquid junction with the end plate via the condensed water.
