Vehicle Battery Cover Sheet

New energy vehicle battery cover

What is the battery cover packaging material for new energy vehicles? New energy battery cover refers to the plate-shaped material used to cover new energy batteries, usually used to wrap and protect the battery shell. Battery covers can be used for various types of new energy batteries, including lithium batteries, lithium cobalt oxide batteries, nickel-hydrogen batteries, etc. New energy battery covers usually need to have a certain strength and wear resistance to protect the internal structure of the battery from the external environment and collision.

At the same time, it also needs to have a certain thermal conductivity to help the battery dissipate heat, as well as lightness to reduce the weight of the vehicle itself. Among them, aluminum alloy is the most common and best-performing material that can meet these requirements.

Importance of car battery cover

New energy vehicle battery cover is a composite oxide of multi-metal materials. It is mainly used to protect lithium batteries from external collisions and extrusions. As a key component of the battery module, the cover material is mainly responsible for ensuring the safe and stable operation of the battery system. The existence of the cover plays an important role in protecting the battery module and preventing external factors from damaging the battery. At present, most pure electric vehicles will choose steel or aluminum alloy materials as the protective shell of the battery pack to ensure the safety of the chassis power battery.

Aluminum sheet for new energy vehicles

With the development of the lightweight trend of automobile parts, the application of battery packs is also developing in the direction of lighter and safer. Aluminum alloy has gradually become the preferred material for making power battery covers due to its excellent processing performance, corrosion resistance and recyclability. Power battery covers made of aluminum alloy can not only effectively reduce internal resistance and overcurrent, but also significantly improve the overall safety of power batteries.

In the production process, the stamping of aluminum plate battery covers is widely used in the production of automotive power battery covers due to its advantages such as simple process and short production cycle. The covers produced by the stamping process are not only structurally complete, but also light in weight, which is very in line with the development trend of lightweight modern automobiles.

Aluminum 3003 battery cover sheet

3003 aluminum sheet is a widely used material for new energy power battery cover and battery housing. 3003 alloy is known for its excellent plasticity, making it easy to form into complex structures without compromising its strength. This property allows for efficient manufacturing processes and adaptable battery housing designs. 3003 battery cover As a lightweight material, 3003 aluminum makes a significant contribution to reducing the total weight of the vehicle. The inherent corrosion resistance of 3003 aluminum ensures that the battery cover remains durable in a variety of environmental conditions, including exposure to moisture and road salt. This extends the service life and reliability of the battery housing.

Advantages of aluminum cover for automotive batteries

Aluminum alloy plates have the characteristics of light weight, corrosion resistance and high strength among many metals. They can play a great advantage in the application of battery covers for new energy electric vehicles. They are high-quality aluminum alloy materials for battery packaging, such as 3003 aluminum plates, which have significant advantages in the application of automotive battery covers.

Good explosion-proof performance

One of the main functions of aluminum shell power battery covers is to prevent the internal pressure of the power battery from being too high and causing explosion. Aluminum plates can effectively increase the flow area of ​​the contact surface between the boss and the conductive sheet, thereby reducing the overcurrent and the probability of the flip sheet being melted, thereby effectively preventing the explosion. This feature ensures the safe operation of the power battery under extreme conditions.

High safety performance

When the internal pressure of the power battery reaches the specified explosion specification range, a large amount of material in the power battery can be quickly discharged outward through the pressure relief hole of the top cover, thereby ensuring the safety performance of the power battery. Aluminum plates have good ductility and plasticity, which enables the battery cover to form an effective pressure relief structure during the manufacturing process, further improving the safety of the battery.

Strong internal resistance performance

The use of aluminum metal materials can reduce the internal resistance of the battery. Aluminum is resistant to high temperatures, has good insulation and sealing effects, and is also small and lightweight. These properties make aluminum sheets an ideal material for manufacturing automotive battery covers, helping to improve the energy density and cycle life of batteries.

Aluminum sheets are lightweight

Aluminum is much lighter than other metals such as steel. This helps reduce the overall weight of the vehicle, which means lower energy consumption and higher performance, higher fuel efficiency for internal combustion engine vehicles, and longer mileage for electric vehicles (EVs).

High thermal conductivity

The battery aluminum cover has excellent thermal conductivity and can effectively dissipate heat. This maintains optimal battery temperature, extends battery life and improves performance, as batteries generate a lot of heat during operation.

Strong corrosion resistance

When used as a battery protection material, aluminum sheets naturally form a protective oxide layer that resists corrosion, which is especially important for vehicles exposed to harsh environmental conditions such as road salt, humidity, and extreme temperatures. It can well extend the service life of the battery cover and reduce maintenance costs.

High mechanical strength and long service life

Modern aluminum alloy battery cover plates are strong and lightweight, which can withstand mechanical stress and protect the battery pack from external impacts such as road debris or collisions, improving safety by protecting sensitive battery components.

Recyclability and sustainability

Aluminum is highly recyclable without losing its properties, making it an environmentally friendly choice. It takes much less energy to recycle aluminum than to produce new aluminum.

Aluminum plates are easier to manufacture

Aluminum plate alloys are versatile and can be easily molded, stamped or extruded into the complex shapes required for modern battery designs. Reduce manufacturing complexity and costs while enabling innovative design solutions.

Good fire resistance

Aluminum plate battery cover materials are non-flammable and do not release toxic gases when exposed to high temperatures. This is particularly important in the case of thermal runaway of the battery. It can improve safety by reducing the risk of fire-related hazards.
