Cell temperature sensing apparatus for a battery module

A printed circuit board (14) supported over the top surface of a multi-cell battery module (10) for battery cell voltage and temperature monitoring has an array of openings (28) in alignment with selected battery cells (12) for receiving temperature-sensing units (16,18) that electrically couple with contacts (32) formed on the printed circuit board and resiliently engage the cases of the selected battery cells. Each such temperature-sensing unit (16,18) includes a printed circuit board mountable lamp socket (18a) and a lamp socket insert (18b) including a thermistor and a compressible element that maintains the thermistor in thermal proximity to the battery cell case when the temperature-sensing unit (16,18) is installed in a respective printed circuit board opening (28).
