In most cases, you will find aluminum and stainless steel battery cabinets. Of course, we have galvanized steel, plastic, and composite materials. A good material for the battery box should be: So far, aluminum and stainless steel guarantee better performance. Apart from these 4, you may classify battery box enclosures depending on:
When the complete battery enclosure is made of extruded aluminium, it helps in creating a natural electromagnetic shield that prevents interference with other electronic components in the vehicle. Aluminium extrusions also allow better energy absorption in case of an accident, compared to steel or carbon fibre.
Aluminium with its lighter weight helps with complex and customized formability essential for deep draws of vehicle battery pack design and in reducing the overall vehicle weight which has a direct impact on the energy consumption.
Aluminum: Aluminum is a lightweight and strong material that is well-suited for battery casings. It is also resistant to corrosion and can be easily formed into complex shapes. However, aluminum is more expensive than other materials, such as steel. Steel: Steel is a strong and durable material that is also relatively inexpensive.
Aluminum battery enclosures or other platform parts typically gives a weight saving of 40% compared to an equivalent steel design. Aluminum is infinitely recyclable with zero loss of properties. At end of life 96% of automotive aluminum content is recycled. Recycling aluminum only requires 5% of the energy needed for primary production.
Battery performance also varies with the quality of aluminium used. Strength and resistance to impact – The batteries need to be protected from vagaries of weather, road debris, stone impacts or possible vehicle crashes. So it is important that a high strength material like aluminum is used for holding the batteries.
