Abstract
The invention relates to a method for selecting candidate energy storage cells for balancing of an electrical energy storage pack (1) comprising a plurality of energy storage cells (3). The method comprises calculating (S212) a probability that a balancing action on the selected group of cells results in that at least one of the future state of charge is lower than a lower threshold present state of charge or higher than a higher threshold present state of charge, the probability being indicative of superfluous leakage or overcharging. The probability is based on the future state of charge for each of the cells and on the statistical inaccuracy. If the probability is indicative of that superfluous leakage or overcharging is unlikely to occur, selecting (S214, S214′) the group of cells as candidates for a balancing action. The invention further relates to a corresponding system and to a vehicle.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
