EATHU Foundry: Quality Custom Aluminum Battery Housing Solutions

Against the backdrop of today's growing demand for energy storage, customizing a suitable die-cast aluminum battery enclosure has become a focus of attention for many companies and users. When faced with the choice of an energy storage battery enclosure, in many cases instead of a drawn or extruded aluminum case, the choice is a die-cast aluminum enclosure. This choice stems from the fact that die-cast aluminum housings are more efficient and cost-effective to manufacture while meeting multiple performance needs. In this article, we'll take an in-depth look at custom die-cast aluminum battery housings and analyze them from a variety of perspectives, including performance, manufacturing processes, and cost, to help you create a battery housing that best meets your needs.

Key Requirements for Energy Storage Battery Enclosures

The design of energy storage battery shell needs to consider a variety of requirements, mainly including mechanical properties, protective properties, thermal management, safety performance, electrical performance and manufacturing process.

Mechanical properties

High strength: 

the battery shell needs to be able to withstand storage, transportation and use of collision, extrusion and other external impacts.

Good toughness:

good toughness can effectively absorb the impact energy, to ensure that the shell in the environment of large temperature changes can still maintain stability.

Strong shock resistance: 

it can effectively buffer the vibration and protect the internal structure of the battery from damage.

Protective performance

Waterproof: 

prevent water from entering the battery shell, leading to short circuit or corrosion of the battery.

Dustproof: 

Avoid dust and impurities affecting the normal operation of the battery.

Moisture: 

Ensure that the battery shell can effectively prevent the battery from moisture in humid environments.

Corrosion resistance: 

The battery shell should have good corrosion resistance and be able to be used in various environments.

Thermal management

Good thermal conductivity: 

good thermal conductivity to help the battery dissipate heat in a timely manner to maintain a suitable working temperature.

Reasonable heat dissipation design: 

design heat sinks or ventilation holes and other measures to improve the heat dissipation efficiency, to ensure that the battery will not overheat in the process of charging and discharging for a long time.

Safety performance

Good flame retardant: 

In the event of battery failure, the shell should be able to effectively prevent the spread of fire to avoid fire accidents.

Explosion-proof performance: 

the shell needs to withstand a certain amount of explosive pressure to protect the surrounding personnel and equipment.

Electrical performance

Good insulation: 

effectively prevent the battery from contacting external conductive objects to prevent short-circuit phenomenon.

Electromagnetic shielding: 

the shell has a certain electromagnetic shielding function, to prevent the electromagnetic interference of external equipment on the performance of the battery, but also to reduce the battery on the electromagnetic interference of external equipment.

Manufacturing process

High precision: 

the shell needs to have high manufacturing precision to ensure close cooperation with the internal components of the battery.

Good processability: 

the choice of materials should have good processability to meet different design requirements, to ensure production efficiency and product quality stability.

Preparation work before customizing energy storage battery enclosure

Before customizing the die-cast aluminum battery enclosure, a series of preparations are required, including clarifying requirements, design considerations and material selection.

Clarify requirements

Battery type:

Different types of batteries (e.g., lithium, lead-acid, etc.) have different size, shape, and performance needs. Understanding the type and characteristics of the battery will help determine the design and size of the enclosure.

Size Requirements:

Determine the external dimensions of the enclosure based on the size and number of batteries, taking into account mounting space constraints to ensure that the enclosure can be installed smoothly.

Mounting method:

The battery enclosure can be installed in a variety of ways such as fixed, removable, wall-mounted and so on. According to the actual application requirements to choose the appropriate installation method.

Design Considerations

Structure design:

Design the structure of the enclosure according to the shape and number of batteries to ensure that the batteries are safely and stably placed inside the enclosure, and provide the necessary sealing design to prevent the entry of moisture, dust or other contaminants.

Heat dissipation design:

Consider the heat generated by the battery during charging and discharging, and design suitable heat dissipation solutions, such as heat sinks or ventilation holes, to ensure good thermal management performance.

Wall thickness selection:

Select a reasonable wall thickness according to the size and strength requirements of the battery casing. Too thin a wall thickness may lead to insufficient strength of the casing, while too thick will increase the cost and production difficulty.

Material Selection.

Choosing the right material is an important part of custom die-cast aluminum battery enclosures. Common materials include aluminum alloys, zinc alloys and magnesium alloys, each of which has its own unique advantages and applicable scenarios.

Aluminum alloy:

Characterized by light weight, high strength, good thermal conductivity and high corrosion resistance, it is widely used in applications that require reduced weight and increased strength.

Zinc alloy:

With better casting performance, suitable for manufacturing shells with complex shapes, and at the same time lower cost, suitable for cost-sensitive applications.

Magnesium Alloy:

Is the lightest of the three alloys and is suitable for extreme lightweight applications, while also offering better vibration resistance and electromagnetic shielding. Finding the right die-cast aluminum enclosure supplier

When choosing a supplier of die-cast aluminum battery enclosures, you should focus on the following points:

Production capacity

The supplier should have sufficient production capacity to deliver on time and meet the demand for mass production.

Quality control system:

Excellent suppliers usually have a strict quality control system, which can ensure the precision and quality of the enclosure.

Technical strength:

The supplier should have rich design and manufacturing experience and be able to provide professional technical support.

Product cases:

Check the supplier's product cases to understand its performance in similar projects.

Service attitude:

Choosing a supplier with high efficiency, smooth communication and positive attitude can guarantee the smooth progress of the project.

Conclusion：

Customizing die-cast aluminum battery housings is a complex process that involves multiple considerations. By reasonably selecting materials, carefully designing the shell structure and considering multiple performance requirements, a high-quality shell can be customized to meet the requirements for use in energy storage batteries. When looking for a suitable supplier, you should not only examine its production capacity and technical level, but also consider its quality control system and service attitude.
