In an embodiment a cell-monitoring connector includes a housing including a lock portion corresponding to a groove portion defined by lock recesses stacked and overlapped in the first direction, wherein the lock recesses are formed in at least one of upper portions or lower portions of terminals protruding in a second direction, the second direction intersecting the first direction toward the cell-monitoring connector from side portions of separators included in the plurality of unit cells and a connector position assurance (CPA) including a lower portion configured to be inserted into the lock portion of the housing in a third direction and to be locked in the groove portion and an upper portion extending from the lower portion in the third direction, the upper portion having a top surface having an area larger than an area of the lower portion in a direction intersecting the third direction.

Cell-monitoring connector for fuel cell

A fuel cell vehicle includes a cell stack, a DC level converter, an output unit, a first switching unit disposed between a positive output terminal of the DC level converter and a positive input terminal of the output unit, a second switching unit disposed between a negative output terminal of the DC level converter and a negative input terminal of the output unit, a resistor and a third switching unit connected to each other in series between the positive output terminal of the DC level converter and the negative output terminal of the DC level converter, a fourth switching unit disposed between a contact point between the resistor and the third switching unit and the positive input terminal of the output unit, and a controller for controlling switching operation of the first, second, third and fourth switching units according to an operation mode.

Fuel cell vehicle

A fuel cell vehicle includes a fuel cell and a junction box. The fuel cell includes at least one cell stack including a plurality of unit cells in a stacked configuration, heaters disposed at end portions of the at least one cell stack, current collectors disposed at the end portions of the at least one cell stack, a terminal block electrically connecting the current collectors and the heaters to the junction box, a positive bus bar and a negative bus bar electrically connecting the current collectors to the terminal block, and a positive wire and a negative wire electrically connecting the heaters to the terminal block. The junction box includes a first switching unit disposed between the positive wire and the positive bus bar, and a second switching unit disposed between the negative wire and the negative bus bar.
