The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system. Due to manufacturing irregularity and different operating conditions, each serially connected cell in the battery pack may get unequal voltage or state of charge (SoC).
A battery pack, as shown in Figure 2, typically has two operating modes: charging mode and discharging mode. Figure 2: Operating modes in a BMS . In charging mode, a charging circuit charges the battery pack; current flows into its HV+ terminal. In discharging mode, the battery pack provides power to an external load.
Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Parallel connection attains higher capacity by adding up the total …

Connecting a battery in series is when you connect two or more batteries together to increase the battery systems overall voltage, connecting batteries in series does not increase the capacity only the voltage. For example if you connect four 12Volt 26Ah batteries you will have a battery voltage of 48Volts and battery capacity of 26Ah.
How flexible is this with pack voltage? The following table shows cell capacities grouped in columns, the top half of the table then shows ~800V packs with 192 cells in parallel and the bottom half shows the ~400V packs. You can immediately see that the high capacity 200Ah cell produces a minimum pack capacity ~138kWh at ~800V.
