As more cells are added in series, the electrical potential of the battery pack increases. This enables electronic devices that require higher electrical potential to operate at their required voltages.
High efficiency of battery packs can be achieved by effectively charging, discharging and resting the battery cells at the right time. Unbalanced cells in a pack degrade the pack's performance and also the SOH of other cells. Till now, the SOH as a driving factor for reconfiguration has been least explored, except for the work done in .
With the higher water level, water released from the bottom of the dam will drain with greater force. Batteries which have cells in series, serve the same purpose in enabling more “force” (voltage) behind the electricity that is available from the battery pack. Figure 2 The other method that cells can be arranged in a battery pack is in parallel.
In order to increase the operating voltage as well as the capacity of battery systems, a combination of series and parallel connected cells are required. Cells are connected in series to increase the voltage rating and in parallel to increase the capacity or current rating. Two topologies that are possible within this section are:
