Abstract
A method of charging a rechargeable battery pack installed in an electric vehicle is provided in which the charging system includes a switching circuit that is operable in at least a first mode and a second mode. In the first mode the switching circuit couples the power supply and an external power source to both a heater and the charging circuit, the heater providing a voltage divider circuit within the charging circuit. In the second mode the switching circuit couples the power supply and the external power source only to the charging circuit, bypassing the heater.
