Do new energy trucks put forward new requirements for accessories?

With the advancement of the country's "dual carbon" strategy and the rapid development of green logistics, new energy trucks are gradually becoming the new main force in the transportation industry. Compared with traditional fuel trucks, new energy trucks have obvious differences in power systems, intelligent management, and maintenance methods. These changes also put forward new and higher requirements for truck accessories.

1. The three-electric system puts forward higher technical requirements for accessories

The "three-electric system" of new energy trucks-battery, motor, and electronic control, is the core of its operation. The performance of these three systems directly determines the safety, endurance and operating efficiency of the whole vehicle.

For example, power batteries have extremely strict requirements on their module manufacturing process. Key accessories such as welding, thermal management system, and BMS (battery management system) of battery modules all need to adopt highly integrated and high-safety technologies. Especially in long-distance transportation scenarios, high-intensity charging and discharging put forward higher standards for the quality of battery structural parts, cables, and cooling devices.

The motor part not only requires higher efficiency output, but also must have good thermal stability and electromagnetic compatibility. Its internal bearings, stators, rotors and other core parts need to adopt high-precision manufacturing and assembly processes to ensure that the vehicle can run smoothly under complex road conditions.

The electronic control system is the "smart brain" of the whole vehicle, and it has set new standards for the heat resistance and stability of accessories such as inverters, controllers, and wiring harnesses. Under high temperature and high frequency operation, any accessory failure may cause the whole vehicle system to shut down, affecting operational efficiency.

2. Continuous upgrading of accessory manufacturing materials and processes

In order to achieve the design goal of coexistence of lightweight and high strength, new energy trucks have made a lot of innovations in accessory manufacturing. For example, the housing, radiator, bracket and other parts commonly used in electric drive systems have gradually transitioned from traditional steel to new lightweight materials such as aluminum-magnesium alloys and composite materials.

Taking the motor housing as an example, the use of high thermal conductivity aluminum alloy materials not only improves the heat dissipation efficiency, but also greatly reduces the weight of the whole vehicle, thereby improving the endurance. However, this type of material also brings new challenges in precision machining, such as large hole machining and surface finish control, which require more advanced CNC machining and surface treatment technologies.

At the same time, the sealing performance and durability of accessories have become more important. High-performance sealing rings, sealants, insulating accessories, etc. must meet the test of harsh working conditions such as high voltage, high temperature, and high humidity.

3. Challenges faced by the accessories supply chain and after-sales system

The technical barriers of new energy trucks are high, and core components are often monopolized by a few companies. This has led to the supply of some key accessories (such as power batteries, electronic control modules, electric drive axles, etc.) in the after-sales link is still imperfect, the price of accessories is high, and the delivery cycle is long.

Especially for small and medium-sized logistics companies, if the accessories cannot be obtained in time during the maintenance process, it will directly affect the vehicle utilization rate and corporate operating income. In addition, the quality of some alternative accessories in the market is uneven, which is prone to frequent failures and increased maintenance costs.

Industry experts suggest that establishing a stable and open new energy truck accessories supply network is the key to ensuring the healthy development of the aftermarket. Vehicle manufacturers, accessories companies, and maintenance platforms need to build a collaborative mechanism to jointly improve the standardization and generalization of accessories.

4. Intelligence and digitalization improve the efficiency of accessories management

Digital operation and maintenance has gradually become standard in the management of new energy truck accessories. Through technical means such as vehicle networking, remote diagnosis systems, and intelligent scheduling platforms, enterprises can achieve full life cycle management of accessories.

For example, wear parts such as brake pads, air filters, and power steering pumps can be predicted and replaced based on actual wear data to avoid driving failures caused by aging of accessories. At the same time, the cloud maintenance platform can also combine operation data to compare and analyze the performance of accessories of different brands, providing data support for later procurement.

In addition, intelligent spare parts management based on operation routes and task plans can optimize accessories inventory, shorten maintenance response time, and improve vehicle operation efficiency.

Conclusion: Accessories upgrade is the key cornerstone of the development of new energy trucks

New energy trucks are not only an energy revolution, but also a comprehensive upgrade of the accessories industry. From technical performance, manufacturing materials, to after-sales service and intelligent management, accessories are an important basis for supporting the stable operation of new energy commercial vehicles, and their quality, technical level and supply capacity need to evolve simultaneously.

In the future, the new energy truck accessories industry will continue to develop in the direction of "high reliability, lightweight, intelligent, and standardized". Vehicle manufacturers, parts manufacturers, and service platforms need to deepen collaboration, accelerate technological research and development, and improve the parts standard system to empower green transportation and lay a solid foundation for the transformation and upgrading of the commercial vehicle industry.
