What is a Li-ion battery pack?
A Li-ion battery pack is a complex system with specific architecture, electrical schemes, controls, sensors, communication systems, and management systems. Current battery systems come with advanced characteristics and features; for example, novel systems can interact with the hosting application (EVs, drones, photovoltaic systems, grid, etc.).
What is a simplified lithium-ion battery pack?
The basic simplified model of the lithium-ion battery pack, which is equipped with a series of novel cooling systems and includes a single lithium-ion battery and different types of cooling structures, is shown in Fig. 1. The simplified single lithium-ion battery model has a length w of 120 mm, a width u of 66 mm, and a thickness v of 18 mm.
What is the echanical structure of a battery pack?
echanical structure, the basic structure of a battery pack is determined by the desired performance as well as cell characteristics. In this research, the Samsung 35E 18650 cylindrical cells are chosen. 20 battery c
How does a battery pack design work?
Extensive calculations are then carried out to determine the battery pack's energy, capacity, weight, and size. The design involves grouping cells into modules for easier management and protection, while also incorporating cell holders to enhance stability and minimize vibrations.
What are the dimensions of a battery pack?
The battery pack is composed of 10 battery cells and 11 coolant passages in a row. The dimension of a battery cell is 16 mm × 65 mm × 131 mm. The overall dimension of the battery system is 230 mm × 73 mm × 175 mm (length × width × height). And the thickness of the plate of the box is 2 mm, as shown in Fig. 1 (a).
What is the thermal management of Li-ion battery pack?
In the same period, Mahamud et al. studied the thermal management of the Li-ion battery pack using a CFD tool. They also introduced a lumped-capacitance thermal model to evaluate the heat generated by each battery cell. Using this approach, they could investigate cell spacing and coolant flow rate parameters.
