A power supply device in which bars BB extend in one direction and connect the terminals of the battery cells adjacent to each other. The lines (20) are electrically connectable to the bars BB. The tabs TB electrically connect the bars BB to the lines (20). The bar BB is formed of a clad plate formed of a first metal (3A) and a second metal (3B). The bar BB includes first and second holders (3a and 3b), and a tab holder. The first and second holders (3a and 3b) are arranged in the first and second metals, respectively, and hold the terminals at holding positions. The tab holder is arranged in the first metal (3A), and holds the tab TB at a holding position. The impedance between the first holder (3a) and the tab holder is substantially equal to the impedance between the tab holder and the second holder (3b).

A battery unit (1) for a motor vehicle has at least one first battery module (10) and at least one second battery module (12) in a battery housing (14). The first battery module (10) has at least one first electrical connection (16), and the second battery module (12) has at least one second electrical connection (18). The battery housing (14) has an opening (20) and an electrically conductive element (22) can be inserted through the opening (20) for electrically conductively connecting the first electrical connection (16) to the second electrical connection (18).

A battery module includes a plurality of battery cells, a temperature sensor and a case. The plurality of battery cells are aligned in one direction. The temperature sensor has a first surface contacting at least one battery cell of the plurality of battery cells to measure a temperature of the at least one battery cell. The case presses against a second surface of the temperature sensor opposite to the first surface of the temperature sensor. In the battery module, the contact between the first surface of the temperature sensor and the battery cell is maintained by the case. Accordingly, the temperature sensor can precisely measure the temperature of the battery cell, thereby improving the safety of the battery module.

A wiring module includes a busbar for connecting between electrode terminals, an external connection busbar to be connected to an external terminal, a resin protector including a first holding portion for holding the busbar and a second holding portion for holding the external connection busbar and a main cover for covering the first holding portion. The main cover includes a first auxiliary cover for covering the second holding portion and a second auxiliary cover connected to the first auxiliary cover via a hinge portion. The first auxiliary cover is provided with an interfered portion for interfering with an interfering portion of the second holding portion as the main cover is mounted on the resin protector, and the first auxiliary cover is automatically rotated and arranged at a predetermined position by the interference of the interfered portion and the interfering portion.

The invention is directed to an electronic device comprising a first functional body, a second functional body, and at least one serpentine interconnect connecting the first functional body to the second functional body, wherein the serpentine interconnect is suspended in air to allow for stretching, flexing or compression.

The present disclosure is directed to a convertible battery pack having an improved switching circuit. The switching circuit includes a converter element having a plurality of contacts positioned in the converter element such that as the converter element slides within the battery pack the contacts move from a first position to engage a first set of contact pads to a second position to engage a second set of contact pads. The converter element includes a pair of springs for each of the plurality of contacts that force the contacts into engagement with the contact pads but also allow the contacts to adjust for imperfections in the contact pad surface or the manufacturing tolerances of the contact pads or a support board that holds the contact pads.

A busbar (21) is provided for electrically connecting a temperature detecting member 40 to adjacent electrode terminals (12A, 12B) of unit cells (11). The busbar (21) is overlapped with the electrode terminals (12A, 12B) of the unit cells (11). The temperature detecting member (40) includes a plate-like heat transfer plate (42) that is overlapped in an area of the busbar (21) other than an area of the busbar (21) that is to be laser-welded to the electrode terminals (12A, 12B) and is attached to the busbar (21) by laser welding.
