摘要： Methods and systems for determining a position of a battery cell within a battery system comprising a plurality of battery cells are disclosed. Each battery cell has a unique identifier, and each battery cell is configured to experience a change in voltage when an electrical stimulus is applied to the battery cell. The method comprises receiving a first signal associated with a first battery cell experiencing a change in voltage due to an electrical stimulus applied to the battery cell; obtaining the unique ID associated with the first battery cell; determining the position of the first battery cell, based on the received first signal associated with the first battery cell; and associating the determined position with the obtained unique ID of the first battery cell.

摘要： A maturation process for an electric battery cell comprises charging the electric battery cell, subjecting the electric battery cell to a maturation period of at least one day while no electrical load other than a measurement apparatus is connected to the electric battery cell, and taking at least one measurement of the open circuit voltage of the electric battery cell during the maturation period using the measurement apparatus. The measurement apparatus is incorporated into a structure of the electric battery cell, forming an integral part of the electric battery cell. The maturation process further comprises determining whether electric battery cell is defective in dependence on the at least one measurement.
