This disclosure relates to an assembly that cools a traction battery of a vehicle, in particular a hybrid electric vehicle. The assembly can include at least one fuel tank, and at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank. The assembly can further include at least one fuel pump that is arranged in the fuel tank and at least one fuel line that is connected and/or can be connected to a pressure side of the fuel pump. A connection portion of the fuel tank is thermally connected to the traction battery. Fuel can be used to cool the connection portion, which cools the traction battery.
