  • System and method of limiting degradation of the battery by prohibiting over-charge with measured temperatures
    Patent number: 8237408
    Abstract: A battery charging apparatus and method adapted to reduce battery capacity as a function of increased temperature thereby permitting partial charges at temperatures in excess of manufacturer's recommendations. The method includes steps of reducing charging current and charging voltage as a function of battery temperature thereby averting chemical instability within the battery. The apparatus detects battery temperature and includes a controller that will control charger voltage and current as a function of temperature and determine a suitable charging capacity.
    Type: Grant
