Abstract

A temperature and electrolyte sensor for a battery includes a probe that is electrically conductive and thermally conductive and configured to be disposed in a liquid electrolyte of the battery. The sensor further includes a thermal coupler coupled to the probe, a temperature determination circuit electrically thermally coupled to the probe and configured to output a signal indicative of a temperature of the probe, and a fluid detection circuit electrically coupled to the thermal coupler and configured to output a signal indicative of a presence of the liquid on the probe. The temperature determination circuit and fluid detection circuit may be disposed in a housing of the sensor, and the probe may extend from the housing.
