ABSTRACT:
A method and apparatus for charging the traction battery of an electric vehicle are provided. Charging energy is delivered from a charging station at a predetermined voltage and at a delivery frequency in the range of from 10 kHz up to 200 kHz, The charging energy is transferred to the vehicle through an inductive coupler, having a primary side connected to the charging station and a secondary side mounted within the vehicle. A rectifier is mounted in the vehicle and interposed between the secondary side and the battery. When the vehicle is connected to a charging station, it is interrogated to determine the nature of the charge controller that is on board the vehicle; and logic decisions invoking the particular mode for charging the vehicle are made depending on the nature and type of charge controller that is on board the vehicle. The value of initial charging current is set either by an on board battery charging control module in the vehicle, or by the charge control module which is present in the charging station; or alternatively, by being preset at the charging station. Initial charging current, and the amount of charging energy to be delivered, may be established by insertion of a card into a data interface on the charging station. Under controlled conditions, a plurality of vehicles may be charged at a single establishment having a plurality of charging stations, by distributing energy to any one vehicle according to priority criteria to be established.
