1. An electric vehicle charging station, comprising:
a battery charging module configured to provide charging energy to a secondary battery of an electric vehicle;
an electromagnetic energy generator configured to generate and transfer electromagnetic energy, by contactless energy transfer means, to the electric vehicle;
a communication interface configured to receive a battery temperature of the secondary battery from the electric vehicle; and
a control unit configured, upon determining that the battery temperature of the secondary battery is below a predetermined lower temperature limit suitable for charging the secondary battery at a high charging power, to activate the electromagnetic energy generator and to generate and transmit the electromagnetic energy to the electric vehicle to cause the secondary battery to be heated,
wherein the control unit is further configured to, upon determining that the battery temperature of the secondary battery exceeds the lower temperature limit, activate the battery charging module to initiate charging the secondary battery at the high charging power.
