Battery cell position determination

A processor for determining a position of a battery cell within a battery system comprising a plurality of battery cells, each battery cell having a unique identifier, ID, and each battery cell configured to experience a change in voltage when an electrical stimulus is applied to the battery cell, the processor being configured to:

• receive a first signal associated with a first battery cell experiencing a change in voltage due to an electrical stimulus applied to the battery cell;
• obtain the unique ID associated with the first battery cell;
• determine the position of the first battery cell, based on the received first signal associated with the first battery cell;
• and
• associate the determined position with the obtained unique ID of the first battery cell.

A method of determining a position of a battery cell within a battery system comprising a plurality of battery cells, each battery cell having a unique identifier, ID, and each battery cell comprising a processing device configured to emit an activation signal, the battery system being assembled in accordance with a predefined assembly sequence, and the method comprising:

• receiving an activation signal associated with each one of the plurality of battery cells comprised within the battery system, each activation signal enabling the unique ID of the associated battery cell to be obtained;
• associating a time coordinate with each received activation signal;
• determining an activation sequence defining an order in which the processing devices associated with the plurality of battery cells are activated based on the time coordinate associated with each received activation signal and the unique ID associated with each battery cell;
• and
• determining the position of each battery cell based on the activation sequence and the predefined assembly sequence.
