1. Typical Application Scenarios

Different new energy industries have diverse requirements for cable assemblies and wires, which need to adapt to harsh working environments and meet strict performance standards. The typical application scenarios are as follows:

1. New Energy Vehicle Scenarios

• High-voltage power transmission: Connecting battery packs, motors and charging systems, with working voltage up to 1000V, requiring high insulation strength, large current-carrying capacity and excellent electromagnetic shielding performance to avoid interfering with vehicle electronic systems. For example, the 800V architecture adopted by Porsche Taycan and Hyundai IONIQ 5 requires special high-voltage cable assemblies to realize ultra-fast charging.
• Charging connection: AC charging cables need good flexibility and wear resistance, while DC fast charging cables need to bear high current (200-300A) and be equipped with multi-layer shielding structures to ensure charging safety and efficiency.
• Vehicle-mounted auxiliary systems: Connecting vehicle-mounted sensors, controllers and intelligent terminals, requiring small size, light weight and stable signal transmission to adapt to the complex space and temperature environment inside the vehicle.

2. Photovoltaic Power Generation Scenarios

• PV array connection: Cables connecting PV panels work in DC 1000-1500V environment, exposed to outdoor high temperature, strong ultraviolet radiation and large temperature difference for a long time, requiring excellent weather resistance, UV resistance and aging resistance, usually using XLPE insulation materials and polyolefin outer sheath.
• Inverter connection: Connecting PV arrays and inverters, requiring flame-retardant performance to prevent fire risks, and adapting to the voltage conversion requirements of inverters (380V/220V).
• Grid connection: Transmitting the electric energy converted by inverters to the power grid, requiring high insulation strength and low energy loss to ensure efficient power transmission.

3. Wind Power Generation Scenarios

• Internal motor connection: Working in the environment of strong electromagnetic interference and frequent mechanical vibration, requiring good electromagnetic shielding performance and high and low temperature resistance, usually using copper wire braided shielding cables and high and low temperature resistant rubber materials.
• Collector line connection: Collecting electric energy from multiple wind turbines and transmitting it to the step-up substation, with voltage level of 10-35kV, requiring high insulation strength and mechanical protection performance, and adopting armored cables for direct burial or cable trench laying.
• Offshore wind power special scenarios: Needing to resist seawater erosion, salt fog corrosion and harsh marine climate, requiring higher corrosion resistance and waterproof performance, and passing strict international environmental certification.

4. Energy Storage Scenarios

• Battery module connection: Connecting energy storage battery modules, bearing the stress of rapid current change during charging and discharging, requiring good thermal stability and electromagnetic shielding performance to ensure the stable operation of the energy storage system.
• Grid connection: Realizing two-way transmission of electric energy between energy storage systems and the power grid, with voltage levels of 10kV, 35kV, etc., requiring compliance with high-voltage cable standards and adaptability to indoor and outdoor environments.

III. Future Development Trends

Driven by technological innovation, policy guidance and market demand, the new energy cable assembly and wire industry is moving towards high-end, intelligent, green and integrated development, with the following key trends:

1. High-performance and Specialized Development

With the continuous upgrading of new energy equipment, the performance requirements for cable assemblies and wires are becoming more stringent. High-temperature resistance, high pressure resistance, waterproof and dustproof, corrosion resistance, and low energy loss have become basic requirements. At the same time, the localization rate of high-end products has exceeded 60%, but there is still room for breakthrough in the localization of high-voltage/ultra-high voltage insulation materials. For example, smart grid and offshore wind power fields require cables to meet higher environmental adaptability and service life requirements, and the R&D and application of special materials (such as low-smoke halogen-free flame-retardant materials and high-temperature superconducting materials) will become the focus of industry competition.

2. Lightweight and Miniaturized Development

In new energy vehicles, aerospace and other fields with strict requirements on weight and space, lightweight and miniaturized cable assemblies and wires have become an inevitable trend. By adopting aluminum conductors, thinner insulation layers and optimized structural design, the weight of cables can be reduced by up to 40% without affecting performance, which helps to improve the energy efficiency of equipment and save installation space. For example, Tesla has adopted aluminum-based cable assemblies to replace traditional copper wires, achieving significant weight reduction effects.

3. Intelligent and Digital Development

The integration of intelligent technologies such as sensors and Internet of Things (IoT) into cable assemblies and wires has become a new trend. Embedded sensors can monitor the temperature, current, mechanical stress and other parameters of cables in real time, realizing predictive maintenance, reducing failure risks and improving the reliability of the entire system. At present, NIO and Xpeng are testing intelligent cable assemblies that can detect overcurrent and overheating of charging cables and battery packs, and automatically notify the vehicle management system to prevent safety hazards. At the same time, digital twin technology is used to optimize cable design and layout, improving the efficiency of R&D and production.

4. Green and Low-Carbon Development

Guided by the global “dual carbon” goal, green and low-carbon has become the core direction of the industry. The development of environmentally friendly cable materials (such as recyclable insulation materials and low-smoke halogen-free materials) can reduce environmental pollution during production, use and disposal. At the same time, optimizing the cable structure to reduce energy loss during transmission is also an important part of green development. For example, the new energy intelligent cables independently developed by some enterprises can replace traditional copper core cables, with smaller contact resistance, larger current-carrying capacity and lower line loss, achieving energy saving and consumption reduction effects.

5. Integration and Service-Oriented Development

The industry is gradually transforming from a single product supply to a one-stop solution service, integrating cable R&D, design, production, installation, maintenance and other links to provide customized solutions for clients. Enterprises are shifting their profit model from “material processing fees” to “system solution services”, establishing strategic cooperation with new energy main engine factories and EPC general contractors, and providing value-added services such as full-life cycle management and online monitoring of cables. At the same time, with the acceleration of global industrial integration, the export proportion of high-end new energy cables is increasing, and enterprises need to obtain IEC, UL, CE and other international certifications to expand the global market.

6. Industry Concentration Improvement

The new energy cable industry is accelerating integration, with small and scattered enterprises gradually withdrawing from the market, and leading enterprises expanding their advantages through mergers and acquisitions and integration. The CR10 (top 10 market share) of the industry has increased from 9.8% in 2020 to 14.6% in 2025, and the industry pattern of “stronger and stronger” is gradually taking shape. Enterprises with core technologies, strict quality control and perfect service capabilities will gain more market share in the competition.
