Abstract: A voltage detection unit includes: a voltage detection terminal having a first location configured to be conductively connected to a detection target; a plate-shaped housing having a terminal accommodating recess accommodating the voltage detection terminal; a cover configured to be locked to the housing at a temporary locking position where the first location of the voltage detection terminal accommodated in the terminal accommodating recess is not covered and a final locking position where the first location is covered; a temperature measurer accommodating a temperature-measuring element and attached to the housing; and an electric wire conductively connected to a second location of the voltage detection terminal and drawn out to the outside of the housing. The temperature measurer is arranged such that at least a part of the temperature measurer is overlapped with the voltage detection terminal in a plate thickness direction of the housing.

Abstract: A conductive module includes: a conductive board; a voltage detection terminal having a first location configured to be conductively connected to the conductive board; a temperature measurer including a temperature-measuring element and a case holding the temperature-measuring element; a plate-shaped housing assembled to the conductive board, the housing having a terminal accommodating recess accommodating the voltage detection terminal and a temperature measurer accommodating recess accommodating the temperature measurer; a heat-conductive filler disposed in a recessed groove of the temperature measurer accommodating recess; a cover configured to be locked to the housing at a temporary locking position where the first location of the voltage detection terminal accommodated in the terminal accommodating recess is not covered and a final locking position where the first location is covered; and an electric wire conductively connected to a second location of the voltage detection terminal and drawn out to the o

Abstract: A first board-shaped member includes a conductive plate disposed between a plurality of stacked power storage modules, a battery stack plate including a board-shaped insulating housing having a fitting groove recessed in a side face of the board-shaped insulating housing so as to fit with a side edge of the conductive plate, a sealing material supply groove respectively provided in front and back faces of the insulating housing along an extension direction of the fitting groove, a through hole that communicates with the sealing material supply groove and the fitting groove, and a sealing material pre-filled into the fitting groove and extruded from the fitting groove to the front and back faces of the insulating housing through the through hole and the sealing material supply groove when the side edge of the conductive plate is fitted into the fitting groove.

Abstract: A voltage detection unit includes a voltage detection terminal having a first location being conductively connected to a detection target, a board-shaped housing having a terminal accommodating recess in which the voltage detection terminal is accommodated, a cover locked to the housing at a first temporary locking position where the first location of the voltage detection terminal accommodated in the terminal accommodating recess is not covered and a final locking position where the first location is covered, and an electric wire conductively connected to a second location of the voltage detection terminal and drawn out toward the outside of the housing. The housing includes a guide portion guiding the cover from the outside toward the first temporary locking position, and a first wall abutting on the cover when the cover is positioned at the first temporary locking position in a moving direction in which the cover is guided.

Abstract: A temperature detection unit includes a board-shaped housing having a board side face provided with a recess configured to be fitted with a side edge of a conductive board disposed between a plurality of stacked power storage modules, and a temperature detection sensor mounted on the housing and configured to measure a temperature of the power storage modules. The housing is provided with a sensor accommodating recess accommodating the temperature detection sensor. A plate end face on one side facing an intersecting direction with a direction that the board side face of the housing faces is provided with an opening configured to allow a temperature wire connected to the temperature detection sensor to extend toward the outside. The sensor accommodating recess extends obliquely to approach the conductive board from one side toward the other side in the intersecting direction.

Abstract: A bipolar electrode (100) for a metal hydride battery includes a current collector (10), a negative electrode active material layer (20) provided on a first surface (10A) of the current collector (10), and a positive electrode active material layer (30) provided on a second surface (10B) of the current collector (10). The negative electrode active material layer (20) contains a metal hydride. The current collector (10) includes a steel sheet (13) and a Ni—Fe alloy layer (15) formed on at least one surface of the steel sheet (13).
