Abstract: A cooling system for an electric vehicle includes an on-board charger in cooling fluid connection with a cooling fluid pump, a cooling system radiator, a vehicle component and a cooling fluid being pumped through each of the on-board charger and the vehicle component by the cooling fluid pump. The on-board charger includes a heat exchanging arrangement arranged on an outside surface of a housing of the on-board charger. When an airflow generated from the vehicle driving flows over the heat exchanging arrangement, the heat exchanging arrangement cools the cooling fluid pumped through the on-board charger by means of heat exchange between the cooling fluid and the airflow, thereby increasing the cooling of the vehicle component.
