Patent Images
1. A method for charging a solar battery using a system having at least one solar panel, a controller, at least one temperature sensor, a battery charger, an over voltage protection circuit, an over current protection circuit, a user interface, and a heater, the method comprising:
- receiving temperature of the battery from the temperature sensor;
determining whether or not the temperature of the battery pack is within the optimal range for battery charging;
determining whether the at least one solar panel is producing power;
receive voltage from the battery;
determine whether or not the at least one battery needs to be charged;
if the temperature is within a range for battery charging and the at least one battery needs to be charged, charging the battery pack through the battery charger using the power produced by the solar panel; and
if the temperature is below the range for battery charging and the at least one battery needs to be charged, turning off the battery charger and heating the battery using the heater until the temperature of the battery is within the range for battery charging,wherein the heater is powered by the at least one solar panel.
