Abstract: A battery system and method for assembling such a system. The battery system comprises an enclosure, an array of cells within the enclosure, a coolant comprising a dielectric fluid that is electrically non-conductive, and a PCB installed over the array. The PCB comprises a substrate, a first conductive layer on a side of the substrate opposite the array, the first conductive layer comprising a plurality of cell-bonding pads, and an array of through-holes, each of the through-holes being adjacent to at least one of the cell-bonding pads. The PCB includes positive and negative power pads conductively coupled to the cell-bonding pads to create a power circuit that allows for the transfer of power to and from the array of cells. The PCB includes mounting pads, to at least some of which are installed electronic components that allow for monitoring and/or management of the cells when the battery system is in use. Terminals of the cells are wire-bonded to corresponding cell-bonding pads on the PCB through the through-holes. At least part of one or more cells and at least some of the electronic components are in direct contact with the coolant when the battery system is in use. The coolant enables the transfer of heat from one or more of the cells to one or more of the electronic components and vice versa.
