How To Adjust Cell Capacity

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

Cell capacity adjustment means the adjustment of cell capacity to a target capacity by estimating the capacity of each cell from the no-load voltage at system startup. The voltage of each cell is detected by the Li-ion battery controller and the bypass switch is turned ON to perform the discharge of a cell with the high capacity. Accordingly, the utilization of the capacity of each cell is maximized by adjusting the capacity with the Li-ion battery controller.
