Battery system
A battery system that includes a battery cell. The battery cell defines a proximal end and a distal end where the proximal end is a positive terminal and the distal end is a negative terminal. A first busbar couples to the proximal end and a second busbar couples to the distal end to complete an electrical circuit. A first energy transfer conduit carries a fluid that cools and/or heats the battery cell. The first busbar or the second busbar couple to the first cooling conduit.
