When designing an efficient energy storage system, the configuration of batteries in series and parallel plays a crucial role. Both methods have unique advantages and challenges that can significantly impact the performance of a battery management system (BMS).
In a series configuration, batteries are connected end-to-end, resulting in increased voltage while the capacity remains the same. On the other hand, parallel connections combine batteries side by side, maintaining the voltage but increasing the overall capacity. Does connecting batteries in series affect their lifespan?
A battery parallel connection involves linking multiple batteries together by connecting their positive terminals and negative terminals. This arrangement increases the overall capacity of the battery pack, shares the load evenly among the batteries, and results in a higher current output.
The durability of batteries in series or parallel connections depends on several factors. In a series configuration, batteries are connected end-to-end, resulting in increased voltage while the capacity remains the same.
In general, it is best to connect batteries in series because this increases the voltage while keeping the current the same. However, there are some advantages to connecting batteries in parallel. For example, if you want to increase the current without changing the voltage, then connecting batteries in parallel is the way to go.
This system is used in different solar panel installations and other applications. If we connect two pairs of two batteries in series and then connect these series connected batteries in parallel, then this configuration of batteries would be called series-parallel connection of batteries.
Cell Capacity and Pack Size
A 400V pack would be arranged with 96 cells in series, 2 cells in parallel would create pack with a total energy of 34.6kWh. Changing the number of cells in series by 1 gives a change in total energy of 3.6V x 2 x 50Ah = 360Wh. Increasing or decreasing the number of cells in parallel changes the total energy by 96 x 3.6V x 50Ah = 17,280Wh.
