Abstract
A system and method of detecting battery connection failures relies upon measuring battery cell body temperature and battery connector temperature at a measured current. The difference between these two temperatures is calculated using a software driven comparator. The comparator compares the difference as measured against a predetermined safe difference for the measured current. If the measured value exceeds the predetermined safe value an alarm is given. In one embodiment of the invention the difference between the two temperatures is compared to a predetermined safe difference independent of current measurements.
