Abstract
Measurement of physical properties and individual charge control of the cells of a battery may lead to a longer battery life and to a more reliable operation. The present invention discloses a system, a cell unit, a control unit and a method for the automated management of batteries via a wireless communication link. According to the invention, the life cycle of individual cells of a battery may be tracked and recorded by an external control unit. Advantageously, active control of the battery cells is provided, including the ability to provide a short circuit between respective poles of battery cells.
