摘要： A connector includes a housing and a multi-layer peripheral structure disposed on the housing. The multi-layer peripheral structure is configured to enclose one or more pins and to expand in response to exposure to a liquid for disconnecting the connector from an electronic component without user intervention. The multi-layer peripheral structure may include an outer layer that may include a permeable material, a middle layer disposed within the outer layer, where the middle layer may include a material that expands when wet, and an inner layer disposed within the middle layer.

摘要： An electrode assembly includes a plurality of unit cells each equipped with a pair of electrodes having different polarities. Electrode tabs protrude from the electrodes. The electrode tabs including at least one electrode parallel connection tab and at least one electrode lead connection tab. In a first unit cell of the plurality of unit cells, a current collector of a first electrode among the pair of electrodes is made of a different material from a current collector of a second electrode among the pair of electrodes having the different polarity.

摘要： A battery pack, comprising a first cell and a second cell connected in series, the first cell having a current cut-off device and having a first failure voltage, the current cut-off device being configured to be able to break a circuit in response to a voltage value of the first cell reaching or exceeding the first failure voltage, and the second cell having no current cut-off device. The battery pack may use a soft pack battery as the second cell, having advantages such as high energy density, low impedance, high discharge power, a low rate of temperature rise during high-rate discharge, and flexibility in dimensions.

摘要： In a structure of a disconnect plug of an electric vehicle, a plug bracket is raised from an inside of a battery unit to an inside of a bulge formed on a floor panel under rear seats for preventing a submarine motion of a passenger. In addition, a disconnect plug is detachably attached to a front face of a plug bracket, and an opening for accessing to the disconnect plug is formed on a front wall of the bulge. Further, a cover for covering the opening capable of being opened and closed is provided on a trim beneath a front face of a seat cushion of the rear seats.
