To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
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.
The voltage level of the battery determines the maximum electrical power which can be delivered continuously. Power P [W] is the product between voltage U [V] and current I [A]: The higher the current, the bigger the diameter of the high voltage wires and the higher the thermal losses.
The battery pack will be designed for an average energy consumption of 161.7451 Wh/km. All high voltage battery packs are made up from battery cells arranged in strings and modules. A battery cell can be regarded as the smallest division of the voltage. Individual battery cells may be grouped in parallel and / or series as modules.
One important consideration is the ratio of pack voltage to capacity. In some modern applications, there is a tendency to use smaller cells connected in series to keep the pack size small while increasing the voltage. Finally, cell size can impact the safety of a battery pack.
The high voltage battery pack of Mitsubishi i-MiEV consists of 22 modules made up from 88 cells connected in series. Each module contains 4 prismatic cells. The voltage of each cell is 3.7 V and the total voltage of the battery pack 330 V. Another example is the high voltage battery pack of Tesla Model S, which has:
