Abstract
A battery maintenance device configured to maintain a storage battery. An electrical connection couples the battery maintenance device to the storage battery. Maintenance circuitry couples to the battery through the electrical connection and performs maintenance on the battery. The maintenance circuitry includes an electrical load configured to draw an electrical current from the battery. The electrical current causes the electrical load to heat. A phase change material is thermally coupled to the load. The phase change material has a specific heat index which has a non-linear relationship to temperature to thereby reduce a rate of change in temperature of the electrical load.
