Abstract: The present disclosure relates to a contactor box for an electrical energy storage system of an at least partly electrical vehicle. The contactor box comprises a first ingoing high voltage connection adapted to be connected to a second ingoing high voltage connection of a battery. The contactor box comprises a first outgoing high voltage connection adapted to be connected to a second outgoing high voltage connection of the battery. The first ingoing and the first outgoing high voltage connections are adapted to be disengaged from the battery when the contactor box is removed from the vehicle, and adapted to be engaged with the battery when the contactor box is inserted into the vehicle.

Abstract: The present disclosure relates to a contactor box (201) for an electrical energy storage system (200) of an at least partly electrical vehicle (100). The contactor box (201) comprises a first ingoing high voltage connection (203a) adapted to be connected to a second ingoing high voltage connection (203b) of a battery (210). The contactor box (201) comprises a first outgoing high voltage connection (205a) adapted to be connected to a second outgoing high voltage connection (205b) of the battery (210). The first ingoing and the first outgoing high voltage connections (203a, 205a) are adapted to be disengaged from the battery (210) when the contactor box (201) is removed from the vehicle (100), and adapted to be engaged with the battery (210) when the contactor box (201) is inserted into the vehicle (100).

Abstract: A method for exchanging coolant in a cooling system, which cooling system comprises at least one pump, an inlet conduit, an outlet conduit. The inlet conduit is connected to at least one external coolant source. The method comprises controlling said at least one pump to flow coolant in the cooling system from the at least one coolant source via the inlet conduit, through the cooling system, to the outlet conduit until the coolant in the cooling system has been at least partly exchanged. The disclosure also relates to a control unit configured to control exchange of coolant according to the method, a cooling system comprising the control unit and a vehicle or vessel comprising the cooling system.
