摘要： A battery pack including: a plurality of battery cells; a housing accommodating the plurality of battery cells; a temperature measuring sensor extending from outside the housing to inside the housing along an axial direction by passing through a mounting hole in the housing; and a sealing member. The temperature measuring sensor includes: a pillar part extending along the axial direction; a locking jaw member extending from a lower position of the pillar part to an upper position toward the housing along the axial direction, extending to follow both the axial direction and a crossing direction crossing the axial direction, and providing an elastic bias force along the crossing direction away from the pillar part with respect to the mounting hole in the housing; and an expansion part expanding from a circumference of the pillar part to cover the mounting hole at an upper portion of the mounting hole along the axial direction. The sealing member is between the expansion part of the temperature measuring sensor and the housing and surrounds the mounting hole.

摘要： A device for controlling a pre-charge current generated when electrically connecting a first terminal and a second terminal, according to one embodiment of the present invention, may comprise: a switch for controlling a magnitude of a current flowing between the first terminal and the second terminal; a first resistor for generating a base voltage of a first transistor in proportion to a magnitude of the pre-charge current flowing between the first terminal and the second terminal; the first transistor for limiting the magnitude of the pre-charge current when a voltage generated by the first resistor is equal to or greater than a predetermined threshold voltage; a photocoupler for receiving, in a state insulated from a first power source, an optical signal from the first power source and supplying power; a capacitor charged by the power supplied by the photocoupler; a second transistor for controlling the magnitude of the pre-charge current on the basis of a charging voltage of the capacitor; and a second resistor for controlling an operating time of the second transistor along with the capacitor.
