Abstract
A system for approximating a temperature of a battery includes a sensor configured to provide a temperature measurement of the ambient air, a sensor configured to provide a voltage measurement of the battery, a sensor configured to provide a current measurement of the battery, and signal processing circuitry configured to determine an approximate battery temperature as a function of the measured ambient air temperature, the measured voltage of the battery, and the measured current of the battery.
