Zusammenfassung:	An exemplary system and method for use in cold environments in order to heat a high voltage vehicle battery, such as the type commonly found in hybrid vehicles. Some high voltage vehicle batteries-like those based on lithium-ion chemistries-perform better when their battery temperature is in a certain temperature range. In an exemplary embodiment, a battery heating system includes a switch, a battery heater and a high voltage vehicle battery, and initially uses electrical power from an external power source to heat the battery and then uses electrical power from an internal power source to heat the battery. The switch determines which power source is used to heat the battery, and may be dictated by whether the battery heating system is plugged into the external power source and/or a vehicle propulsion system is active, to cite several possibilities.
