Abstract:

A system is provided for temperature compensating and monitoring the energy of a lithium battery. In this method, a temperature compensation factor is determined according to a value of temperature. A determination is made of the energy usage while the battery operates at that temperature. The temperature usage is then compensated in accordance with the temperature compensation factor. A second temperature, along with a second temperature compensation factor, is determined. A second energy level is determined and compensated as described for the first. A cumulative energy usage is determined according to the first and second compensated energy usage values.
