Abstract
The disclosed technology generally relates to charging a secondary battery of an electric vehicle and more particularly to thermal management of the secondary battery associated with charging. In one aspect, a method of charging a battery of an electric vehicle includes determining that a battery temperature of a secondary battery is below a predetermined lower temperature limit suitable for charging the secondary battery at a high charging power greater than 18 kW. The method additionally includes externally applying, by contactless energy transfer means, electromagnetic energy to an energy conversion module of the electric vehicle. The method additionally includes converting the electromagnetic energy to heat and heating the secondary battery to a temperature above the lower temperature limit. The method further includes charging the secondary battery at the high charging power while maintaining the battery temperature between the lower temperature limit and an upper temperature limit at least in part by controlling a magnitude of the electromagnetic energy transferred by the contactless energy transfer means. Aspects further relate to an electric vehicle charging station, a powering system for an electric vehicle and an electric vehicle charging system.
