The control system (50) is configured for executing a pre-charging process (100) and a cyclic converting process (200). During the pre-charging process (100), the control system (50) controls the pre-charging switch (10) and the switching element Q4 (14) to be conductive to build up a voltage difference in the flying capacitor (20). During the cyclic converting process (200) the control system (50) controls the pre-charging switch (10) to be isolating when the switching element Q1 is isolating.

The present disclosure relates to a cooling system and a charging pile. The cooling system (100) comprises: at least one fan (110) configured to draw airflow from the radial outside during operation and discharge the drawn airflow in the axial direction; and at least one radiator (120), each radiator (120) being disposed to circumferentially surround a corresponding fan (110) of the at least one fan (110), wherein the radiator (120) at least includes a curved section (125) that at least partially follows the contour of the corresponding fan (110); wherein the radiator (120) comprises a plurality of radiator fins (122) arranged in a stacked manner relative to one another along the axial direction, and a gap (121) is formed between at least one pair of adjacent radiator fins (122) in the height direction perpendicular to the circumferential direction and the axial direction, the gap (121) allowing airflow to flow from the circumferential outside of the radiator (120) toward the circumferential inside of the radiator (120).

The invention relates to a method for charging an EV by an EVSE and a respective apparatus. The method comprises establishing a physical connection between the EV and the EVSE, initiating a payment authentication process, recognizing, by the EVSE, an EV identifier, entering an energy transfer stage and providing the price for charging on a display. A payment authentication state is defined for the payment authentication process. The payment authentication state comprises at least an ongoing state and an approved state. The energy transfer stage is entered irrespective of whether the payment authentication state is the ongoing state or the approved state. The price for charging is provided on a display mounted to the housing of the EVSE.
