A battery distribution unit includes a housing having a bottom mounted to a battery case of a battery module and having a component cavity with a contactor therein. The contactor has fixed contacts having terminating ends extending from a bottom end of a contactor housing. The BDU includes terminals at the bottom end of the contactor coupled to the terminating ends and a heat exchanger cap at the bottom end of the contactor. The heat exchanger cap is provided in the component cavity in thermal communication with the fixed contacts and in thermal communication with the battery case of the battery module to dissipate heat from the fixed contacts into the battery case of the battery module.
