Abstract
A battery pack device includes a plurality of energy storage elements configurable in series, each element having at least one switch to selectively connect, disconnect, or bypass the element. The device further includes a switch configured to establish a short circuit between terminals of the battery pack when the pack is disconnected or supplies zero voltage. A control circuit is configured to select at least one first energy storage element in a first state and at least one second energy storage element in a second state, and to cause current to flow from the first element to the second element while the terminals are short-circuited. The control circuit further stops the current when a parameter of the first element, selected from charge, voltage, state of health, temperature, or impedance, becomes equal to a corresponding parameter of the second element or to an average value among multiple elements.
