Tesla’s battery pack has 8,256 cells. These cells are organized into 16 modules, with each module containing 516 cells. This configuration allows for a total capacity of over 100 kWh. Consequently, Tesla vehicles can achieve a vehicle range of over 300 miles, demonstrating efficient energy storage and use in electric vehicles.
For example, a battery pack with a capacity of 100 kilowatt-hours (kWh) may contain several hundred cells, while one with 40 kWh will have fewer cells. The reasoning behind this connection is simple. Each cell contributes a specific amount of energy to the overall pack. If we need to increase the total energy storage, we must add more cells.
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.
The cells in a Tesla battery pack are arranged in modules that contribute to the overall energy storage capacity of the vehicle. Tesla utilizes cylindrical lithium-ion cells, specifically the 18650 and 2170 formats, with the latter being more common in newer models.
The differences in cell count relate to battery capacity and vehicle size. Larger vehicles typically require more energy to operate, resulting in a higher number of cells. The cells in a Tesla battery pack are arranged in modules that contribute to the overall energy storage capacity of the vehicle.
In modern energy storage systems, batteries are structured into three key components: cells, modules, and packs. Each level of this structure plays a crucial role in delivering the performance, safety, and reliability demanded by various applications, including electric vehicles, renewable energy storage, and portable devices.
