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; externally applying, by contactless energy transfer means, electromagnetic energy to an energy conversion module of the electric vehicle; converting the electromagnetic energy to heat and heating the secondary battery to a temperature above the lower temperature limit; and 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.
