Partitioning the battery pack to monitor cell voltages is an extension of the Lee Hart Bridge. Three partitions were chosen to bring the partition voltage down to a safe level when the vehicle is not in use. Increasing the number of partitions also increases the resolution of the cell voltage monitoring. |
