Battery cell temperature measurement system

A battery comprising:

• a plurality of battery cells;
• a plurality of posts, each post of the plurality of posts being coupled to one or more battery cells of the plurality of battery cells, each post having a post temperature corresponding to a temperature associated with the one or more battery cells;
• a case housing the plurality of battery cells and at least a portion of each post of the plurality of posts;
• a cover sealed to the case and comprising a plurality of bushings, at least another portion of each post of the plurality of posts extending from the cover via a corresponding bushing;
• one or more thermally conductive pads, each thermally conductive pad being coupled to one post and one bushing;
• a sensor physically coupled to each thermally conductive pad of the one or more thermally conductive pads, the sensor being configured to measure a temperature associated with at least one battery cell via the thermally conductive pad and a corresponding post;
• and
• a battery management system, BMS, comprising processing circuitry in communication with the sensor and configured to determine a temperature value of each battery cell based on the measured temperature associated with the at least one battery cell.

A method for assembling a system for determining a temperature value of a battery cell, the system comprising a weld, a thermally conductive pad, a sensor configured to measure a temperature associated with the battery cell via the thermally conductive pad, a battery management system, BMS, and a lead, the weld being directly couplable to the battery cell and having a weld temperature corresponding to a temperature associated with the battery cell, the lead having a first end and a second end opposite the first end, the method comprising:

• coupling the first end of the lead to the weld and the second end of the lead to the BMS;
• coupling the sensor to the thermally conductive pad;
• positioning a bottom surface of the thermally conductive pad over the weld and the lead;
• coupling the thermally conductive pad to the weld, at least a portion of the bottom surface of the thermally conductive pad directly contacting only the weld;
• and
• electrically coupling the BMS to the sensor.
