Cylindrical battery pack module

What is a cylindrical battery pack?

Cylindrical battery packs, such as the 18650 battery pack, are designed to fix multiple cylindrical batteries at designated positions to ensure that excessive displacement does not occur under reasonable vibration and shock conditions. The position of the cell is determined by the cell bracket. In extreme cases, the cell bracket may be deformed.

What is a cylindrical battery?

Cylindrical batteries are small in size and are very suitable for battery packs with irregular spaces, making full use of the corner space. Cylindrical cells made of ternary materials have an energy density of 210~250Wh/kg. Large-scale standardized batteries make cylindrical battery packs also have the premise of automated production.

What is a battery module?

The battery modules are made of multiple parallel assemblies which, in turn, comprise a number of battery cells connected electrically in parallel under a specific topological configuration or geometrical arrangement. A battery cell is an electrochemical energy storage device that provides electrical energy from stored chemical energy.

How many cell models should a cylindrical module have?

For cylindrical modules, the detailed model resolution is not recommended as many cells are present and it is important to keep the total number of models between 30 and 50. A number of cell model blocks equal to the value of the NumParallelCells property represents each cell component.
