Abstract:
Energy storage system having one or more battery packs and a system controller for controlling the battery packs. Each battery pack has rechargeable storage cells and a battery pack controller in communication with the system controller. Through the operation of the system controller, battery packs with different initial charge states can be operated in parallel during the charge or discharge process. Discharging multiple battery packs in parallel offers not only higher capacity and longer run time than is available from a single battery pack, but also offers higher peak currents than available from a single battery pack, important in motor control applications. Battery pack design including a battery pack connector with both power and control contacts supporting user replacement of the battery packs.
