Today, we’ll explore the three most crucial elements: cells, battery modules, and battery packs. 1. Cells: The Building Blocks Cells serve as the fundamental building blocks of power batteries, typically lithium-ion batteries.
This is where battery modules come into play. Cells are initially connected and housed within frames to form these modules. Various battery assembly equipment are used to form packs from cells and provide an additional layer of protection, shielding cells from external factors such as heat and vibration.
As a result, cells are connected in series to form a battery module. Series connections elevate voltage, while parallel connections increase capacity. There are three common types of cells: Cylindrical Cells: These are compact, tubular batteries often seen in consumer electronics.
Batteries are comprised of several components that allow batteries to store and transfer electricity. To charge and discharge batteries, charged particles (ions and electrons) must flow in particular directions and through particular components. Although batteries can vary depending on their chemistry, they have
1. Cells: The Building Blocks Cells serve as the fundamental building blocks of power batteries, typically lithium-ion batteries. These cells offer a working voltage ranging between 3V and 5V, which, although respectable, is insufficient for providing the high voltage and capacity needed to propel electric vehicles.
When a Li-ion battery is charging, positive lithium ions flow internally from the cathode to the anode; at the same time, electrons flow externally from the cathode to the anode. When the battery is discharging, the lithium ions and electrons flow in the opposite direction.
