NOVELTY - The system has a conductive interconnector (30) having an inner ring portion welded to an end of a cell (20a). A standoff portion is contiguous with the inner ring portion. Tabs extend from the standoff portion, and are welded to an end of another cell (20b). A washer-shaped insulator (32) is located between a conductive interconnector and the former cell. The insulator has an inside diameter large enough to slide over an exterior surface of the standoff portion. A female receptacle is coupled to one of the tabs to accept a temperature sensor i.e. thermistor.    USE - End-to-end cell connection system for use in a battery (claimed) e.g. power supply system or battery system, of a hybrid electric vehicle.    ADVANTAGE - The receptacle is accessed from outside the brick when the bricks are assembled and connected together to form a battery system, and is provided for a temperature sensor, contiguous with the interconnector, thus reducing the potential for breakage of electrical leads from the temperature sensor, and hence preventing damage of wires from the temperature sensor during assembly and reducing the need for additional hardware. The diameter of the snap insulator ring is approximately equal to the diameter of the crimp joint so that the snap insulator ring can be snapped onto a crimp joint without inadvertent slipping, thus facilitating the assembly process. The insulator is placed between the interconnector and one cell, so that an electrical short between the interconnector and a negative portion of the crimp joint can be prevented when a longitudinally coupled cell group is jostled. The battery is aided by a temperature estimate from a temperature sensor so that the temperature proximate the interconnector provides a good indicator of the internal temperature of the cells, thus providing improved cooling.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a battery comprising a cell assembly.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a partially formed connection between two cells.
