The increments in pack capacity are also 138kWh. The small 5Ah cell allows a more granular approach to pack sizes, the downside is the number of cells that are used and hence the complexity of items such as the busbars. In simple terms the total energy in the pack is just the total nominal voltage x total nominal capacity.
Lithium-ion batteries, particularly the 18650 battery pack design, have become the industry standard for many applications due to their high energy density and long lifespan. Understanding how to calculate a lithium-ion battery pack's capacity and runtime is essential for ensuring optimal performance and efficiency in devices and systems.
Repeating this calculation with a 200Ah cell and the same ~400V pack requirements shows that the smallest total energy for the pack is 69kWh. Also, the increments are 69kWh for each increase in the number of cells in parallel. This could be a very cost driven pack design, but is not so flexible in total capacity.
You can immediately see that the high capacity 200Ah cell produces a minimum pack capacity ~138kWh at ~800V. The increments in pack capacity are also 138kWh. The small 5Ah cell allows a more granular approach to pack sizes, the downside is the number of cells that are used and hence the complexity of items such as the busbars.
