Abstract
The present disclosure provides an improved high watt-hour lithium ion rechargeable battery pack including a plurality of cells not comprising a multiple of eight and an electrical circuit to provide a battery pack that mimics eight cells in series. In particular, the present disclosure relates to a battery pack comprising a non-multiple of eight cells of the type typically used in a 2590 battery pack and a corresponding mechanical packing assembly. The improved electromechanical design may provide an increased capacity and reduced heat of the cells upon discharge as compared to a standard 2590 battery pack, and may also avoid an imbalance that may arise when using multiple internal battery packs. The disclosed improved battery packs require only one control circuit to provide voltage regulation as well as the protection, balancing, and fuel gauge circuit functions for all of the energy cells, leading to reductions in both complexity and cost.
