Battery packs are prone to moisture ingress due to rain, snow or water immersion, which can affect battery safety, while the air and water tightness of the battery housing creates a dense protective layer, delivering excellent water resistance. The battery housing is also chemically and corrosion resistant, preventing corrosion of the battery.
What is the thermal insulation of the battery housing?
What are the performance characteristics of the battery housing?
What are the reasons for choosing ev battery housings?
Composites, in addition to their lighter material qualities, avoid the need for a separate insulation system, which further reduces vehicle weight and helps to streamline the supply and value chain. In the case of metal battery housings, a thermal insulation system needs to be added around the material to maintain the battery's operating temperature. Due to the thermal insulation properties of composite materials, which are highly effective in preventing heat transfer, there is no need to add more weight-adding components to the system.
The aluminium alloy battery pack shell for new energy vehicles, as the carrier of the power battery module, plays a key role in the safe working and protection of the battery module. Its appearance design is mainly from the material, surface corrosion prevention, insulation treatment, product marking and other aspects. To meet the requirements of strength and rigidity and electrical equipment shell protection level IP67 design requirements and to provide collision protection, the battery module in the box in the bottom plate rooted, wire harnesses to a reasonable, beautiful and reliable fixed. The aluminium alloy material used for the new energy vehicle power pack has the characteristics of easy processing and forming, high temperature corrosion resistance, good heat transfer and electrical conductivity. The aluminium alloy shell (except for the shell cover) can be drawn and shaped in one go. Compared to stainless steel, the welding process at the bottom of the box can be omitted, and there will be no problems such as the quality of the cold wind decreasing due to the burning of metal elements when welding is carried out.
The shock absorption and thermal management of the battery module housing is crucial to protect the battery from external shocks. ev battery housing is not only mechanically robust, but also has high voltage insulation properties that resist 800 volts and effectively block high voltage currents, and it has strong fire retardant properties that prevent or retard the spread of flames in the event of a fire. ev battery housing is superior in durability to unfilled P polyamide 6.
In addition, it maintains excellent strength and stiffness when in contact with electrolytes or cooling media and has chemical resistance to inhibit chemically induced damage.
The plastic on ev battery housings can be used in a wide range of battery components, including battery covers, high-voltage connectors, cable supports and battery cooling system piping, as well as components for hydrogen fuel cell vehicles (e.g. hydrogen storage tanks). It can also replace metal in various components for lightweight designs.
