SMART BATTERY SYSTEM AND METHOD OF SMART BATTERY SYSTEM BALANCING

摘要

The present invention provides a smart battery unit, a smart battery system adopted to keep a plurality of smart battery units balanced, and a method of a smart battery system balancing. The smart battery unit comprises at least one battery cell equipped with at least one cell node. According to the present invention the at least one cell node is adopted to perform at least the following functions: measuring at least one parameter of the at least one battery cell, evaluating an actual battery unit state which comprises at least one actual battery cell state of the at least one battery cell of the smart battery unit evaluated based on measured parameter, sending data, which comprises information about the measured parameters and/or the actual battery unit state of the smart battery unit, receiving data, which comprises information about measured parameters of other smart battery units and/or actual battery unit states of other smart battery units, evaluating an actual battery unit state of the other smart battery units based on the received data, defining a targeted battery unit state, which comprises at least one targeted battery cell state of the at least one battery cell defined based on the evaluated actual battery unit state of the smart battery unit and the received data, adjusting the actual battery unit state of the smart battery unit to the defined targeted battery smart unit state by bringing each battery cell of the smart battery unit to the defined targeted battery cell state of the respective battery cell of the smart battery unit.
