ABSTRACT:
A battery charging system and method for charging a plug-in electric vehicle with power from an external power source, such as a standard 110 volt or 220 volt AC wall outlet. The method senses various internal and external conditions and uses this information to charge the plug-in electric vehicle in an optimum fashion that reduces charging time yet avoids damage to components of the charging system. In one embodiment, the battery charging system includes an external power source, a battery charger with sensors for monitoring the external power source and the charger, a battery unit with sensors for monitoring the battery, a battery charging control module for processing the information, and a user interface that allows user-specified custom charging constraints. All of these components, with the exception of external power source, may be located on the vehicle.
