Specification

Material
Aluminium
Most common choice due to its light weight and good structural integrity. Can be easily formed into complex shapes through extrusion processes. Extruded aluminium profiles allow customisation to suit different battery pack designs.
Steel
High strength steel is sometimes used for added rigidity, particularly in situations where high impact resistance is required. Can be heavier than aluminium, affecting vehicle weight.
Composite materials
Fibre-reinforced polymers (FRPs) can provide a good balance between strength and weight. Can be engineered for specific thermal properties and impact resistance.
Advantages of New Energy Vehicles Battery Pack Tray
Lightweight design
The thermoplastic composite battery tray adopts advanced composite technology and achieves a significant lightweight effect by optimising the material ratio and structural design. Compared with traditional metal materials, the thermoplastic composite pallet significantly reduces the weight while ensuring sufficient strength, thus reducing the energy consumption of the whole vehicle and improving the range.
Safety improvement
The thermoplastic composite battery tray focuses on the characteristics of fireproof, explosion-proof and corrosion-resistant, which effectively improves the safety performance of the battery system. In the event of collision or short circuit and other extreme conditions, thermoplastic composite materials can quickly dissipate heat, prevent the spread of fire and protect the battery pack from damage.


Easy to process and recycle
Thermoplastic composite battery tray is not only easy to process and mould during the manufacturing process, which reduces the manufacturing cost, but also can be recycled and reused after the vehicle is scrapped, which reduces the waste of resources and environmental pollution, and is in line with the concept of circular economy.
Thermal management performance
For solid-state batteries, aluminium alloy pallets have better thermal management performance. Aluminium alloy has good thermal conductivity, which can help solid-state batteries to effectively transfer heat, reduce power consumption and save energy.
Types of New Energy Vehicles Battery Pack Tray
Steel Battery Tray
At present, the steel battery tray is mainly used for the material of high-strength steel, which has the price of economic, excellent processing and welding functions, access to the favour of many enterprises; In the actual road conditions due to the battery tray by the impact of various conditions, such as easy to be affected by the impact of gravel, etc., and the steel tray only has a good resistance to the impact of stone ability. Steel tray also has its limitations: First, its weight is large, loaded in the body, so that the new energy vehicle range of one of the important factors; second, steel battery tray due to its rigidity is poor, in the process of collision is prone to extrusion and deformation, which makes the battery damage or even cause a fire: Third, the corrosion resistance of the steel battery tray is poor in different environments is prone to chemical corrosion this will lead to the destruction of the internal battery.
Die-cast Aluminium Battery Tray
Die-cast aluminium battery tray is the use of the whole one-time molding, which has a flexible design style, tray molding does not need to carry out further welding process, so its comprehensive mechanical properties are higher; As a result of the use of aluminium alloy materials, its weight is also further reduced, therefore, this structure of the battery tray is commonly used in the small energy battery packs. However, due to the aluminium alloy in the casting process is prone to undercasting, cracking, cold segregation, depression, porosity and other defects .
Extruded Aluminium Battery Tray
Extruded aluminium alloy battery tray through the splicing of profiles and processing to meet different needs, with flexible design, convenient processing, easy to modify and other advantages; Performance of extruded aluminium alloy battery tray has a high degree of rigidity, resistance to vibration, extrusion and impact and other properties. In the extruded aluminium battery tray welding frame structure is more long false. It is also a more flexible structure, through the welding of different aluminium profiles, processing, can meet the needs of different energy size. At the same time, it is easy to change the design and adjust the materials used. The frame structure is more conducive to lightweight, more conducive to ensure the strength of different structures. The outer frame mainly completes the supporting function of the whole battery system; The inner frame mainly completes the supporting function of the module, water-cooled plate and other sub-modules; In the middle protective surface of the inner and outer frames, it mainly completes the isolation of the battery pack from the outside world and the protection, such as gravel impact, waterproofing, heat insulation and so on. It is worth mentioning that aluminium battery tray is still the most widely used product, and most of the automobile companies will choose aluminium alloy material to produce battery tray.
