1. A battery distribution unit for a battery module comprising:
a housing including a bottom configured to be mounted to a battery case of the battery module, the housing including a component cavity;
a contactor received in the component cavity, the contactor having a contactor housing having a top end and a bottom end, the contactor including a movable contact in the contactor housing movable relative to fixed contacts to create an electrical switch that connects and disconnects the fixed contacts;
terminals at the bottom end of the contactor housing, the terminals coupled to terminating ends of the fixed contacts; and
a heat exchanger cap at the bottom end of the contactor housing, the heat exchanger cap provided in the component cavity at the bottom of the housing, the heat exchanger cap in direct thermal communication with the fixed contacts and configured to be 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.
