New Trend in the Terminal Wire Market in 2025: Surge in Demand for New Energy Vehicles/Energy Storage/3C Electronics

With the rapid development of global intelligent manufacturing, green energy, and consumer electronics, terminal wires, as the lifeblood of electronic systems, are facing unprecedented market opportunities. Especially under the strong driving force of the three high growth tracks of new energy vehicles, energy storage systems, and 3C electronic products, the demand for terminal wire market continues to rise, and the industry landscape is accelerating its reshaping. According to authoritative institutions' predictions, by 2025, the size of China's terminal wire market will exceed 100 billion yuan, with a compound annual growth rate of over 12%.

In this wave of industrial upgrading, traditional universal terminal wires are no longer able to meet diverse and high-performance application scenarios. Instead, professional terminal wires with high reliability, high temperature resistance, miniaturization, customization and other characteristics have become popular products for buyers to compete for orders. This article will reveal the 5 hottest types of terminal wires in 2025 and analyze the technological trends and market logic behind them.

1、 New energy vehicles: High voltage and high current terminal wires become essential

The explosive growth of new energy vehicles has directly driven the demand for high-performance terminal wires in vehicle electrical systems. From power battery pack, motor controller to on-board charger (OBC), every critical component relies on a stable and reliable connection scheme.

Among them, high-voltage and high current terminal wires have become the "lifeline" of new energy vehicle power systems due to their ability to withstand voltages above 600V and currents of hundreds of amperes. This kind of harness usually adopts silver plated copper conductor, XLPE or silica gel insulation material, which has excellent conductivity, heat resistance and aging resistance to ensure the safety and stability of the vehicle under high-speed operation and frequent charging and discharging.

In addition, with the popularization of 800V high-voltage platforms, higher requirements have been put forward for the insulation level, shielding performance, and connection reliability of terminal wires, promoting enterprises to accelerate technological upgrades and product iterations.

2、 Energy storage system: surge in demand for high-temperature and corrosion-resistant terminal wires

Under the promotion of the "dual carbon" goal, application scenarios such as photovoltaic+energy storage, industrial and commercial energy storage, and household energy storage have fully bloomed. The energy storage system operates in harsh environments such as high temperature, high humidity, and salt spray for a long time, requiring extremely high weather resistance for the connecting components.

Therefore, high-temperature and corrosion-resistant terminal wires have become a hot commodity in the field of energy storage. These products often use special materials such as fluoroplastics (FEP/PFA) and silicone rubber, which can work stably in a wide temperature range of -40 ℃ to 150 ℃ and have excellent resistance to ultraviolet radiation and chemical corrosion.

At the same time, energy storage systems have strict electrical safety requirements, and terminal wires also need to pass multiple international certifications such as UL, CE, RoHS, etc. Enterprises with complete qualifications and stable supply capabilities are becoming the preferred partners for integrators to cooperate with.

3、 3C Electronics: Ultra thin micro terminal wire leads the trend of lightweight

In 3C electronic products such as smartphones, tablets, and wearable devices, space is precious and highly sensitive to the size and weight of internal wiring harnesses. The traditional thick and sturdy wire can no longer adapt to the trend of ultra-thin design.

Ultra thin micro terminal wires have emerged, using extremely thin coaxial lines, FPC (flexible circuit board) or extremely thin AWG wires, with a thickness as low as 0.3mm or less, widely used in camera modules, screen cables, TWS headphone internal connections and other scenarios.

This type of terminal wire not only requires small size and strong bendability, but also needs to have good signal integrity to avoid electromagnetic interference affecting the quality of audio and video transmission. With the popularization of new technologies such as Mini LED, foldable screens, AR/VR, the market for micro terminal wires will continue to expand.
