A method, battery module, an energy storage device and a power management system is provided. The capacity of the module and energy storage device is determined during current balancing between cells of the module. The capacity is subsequently used to control power to and from the energy storage device to maintain the energy storage device within a predetermined range of the maximum capacity of the energy storage device. The determined capacity is used as a maximum capacity for the energy storage device.
