Thermal conduction application in new energy vehicles


With the rapid development of new energy vehicles, automotive lithium batteries have ushered in another spring for the battery industry. One of the key technologies for the development of new energy vehicles is the new energy vehicle battery management system, and the thermal management system is the core of the battery management system.

Thermal management of new energy vehicle batteries directly affects the power, reliability and safety of the vehicle. At present, the thermal countermeasures for new energy vehicle battery packs include air cooling, liquid cooling and phase change cooling plus the heat of graphene thermal pads to solve the heat conduction and heat dissipation problem of automobile batteries.

Graphene thermal pads currently play an important role in new energy. It is worth mentioning that graphene thermal pads are widely used in the field of electric energy and are the preferred thermal interface material for power battery thermal solutions. So, what advantages can be achieved by applying graphene thermal pad thermal conduction solutions to power batteries?

Power batteries are an important factor in promoting the development of new energy vehicles. Power batteries provide power for new energy vehicles. With the advancement of power battery technology, the endurance of new energy vehicles has been greatly improved. However, the greater the operating power of the battery, the longer the battery life is used. The heat dissipation will be higher, which requires a more efficient thermal solution.

Current power batteries are equipped with a liquid cooling device, which is embedded between the single cells. At the same time, heat can be transferred to the coolant through a thermally conductive insulation layer. This is how the flowing coolant controls the battery pack. Temperature, but the thermal pad is used outside the cooling layer. The thermal pad is to effectively dissipate the heat generated by the lithium battery when it is working, and also to complete the conduction between cells.电池.jpg

The use of thermal pads can complete the heat transfer between the battery core and the liquid cooling tube, and can also reflect the characteristics of the highest thermal conductivity of the thermal conductive material. Of course, when using this, there is also a buffer battery pack that can withstand impact and shock absorption, which can successfully protect the battery cells. This way, it can protect the battery pack well and reduce the friction between modules. Vibration, this effect is the most ideal.

The application characteristics of thermal pads are very consistent with the dissipation requirements of power batteries, so thermal pads can play a very good thermal conductive role in power battery applications.
