Battery Management Systems for Large Lithium-Ion Battery Packs

Section Addenda

Even if all the cells had exactly the same leakage at room temperature, their leakage would differ in a real world application in which the cells are exposed to different temperatures, from external sources (for example, some cells are closer to an HEV's engine compartment) or internal sources (higher internal resistance in a cell results in more heat generated internally while in use). This effect would not be noticeable in the short run, but may result in noticeable imbalance after some time.
