Protection: The housing provides the first physical protection for the battery pack, preventing mechanical damage, external contamination (such as water, dust, etc.) and overheating of the battery. The packaging system provides sealed protection for the battery unit, preventing the internal components of the battery pack from being interfered with the external environment.
Thermal management: During the battery charging and discharging process, the housing and packaging system share the task of heat dissipation. Through the design of thermal conductive layer, heat sink, cooling pipe, etc., the shell can effectively export heat from the battery to avoid damage caused by overheating of the battery.
Electrical connection: The packaging system ensures that each cell is electrically connected reliably to form a battery pack. It provides a strong connection point to ensure the stability of the electrical system in the battery pack, preventing poor connection wire contact or electrical short circuit.
Safety protection: In the case of abnormal battery pack (such as overcharge, overdischarge, short circuit, overheating, etc.), the safe design of the housing and packaging system plays a crucial role. The housing prevents gas or liquid leaks from the internal battery pack and prevents fire or explosion. The packaging system enhances the compression, impact and high temperature resistance of the battery pack through special materials and designs.
