A battery system includes a battery cell having a battery cell housing, and a housing support external to the battery cell housing. The housing support is formed of at least two split shell segments. Each split shell segment includes a heat conductor inner layer having a plurality of heat-conducting fibers with heat sink ends, and a structural support outer layer overlying the heat conductor inner layer. The structural support layer is made of a fiber-reinforced composite material. A layer of a structural adhesive bonds the respective heat conductor inner layer of each split shell segment to the battery cell housing. A thermal sink is in thermal contact with the sink ends of the plurality of heat-conducting fibers of each of the split shell segments, and the structural support outer layer of each split shell segment is joined to a structural base. Preferably, a number of the battery cells and overlying housing supports extend between a single thermal sink at one end and a single structure base at the other end, forming a battery pack.
