Why are Automotive Cable so Important?

Ignoring the right cables selection could lead to premature system failure

Automotive cable has two key functions: power delivery and signal transmission.

Power cable withstand high voltage and high temperatures, supporting power battery and motor control modules, and high energy consumption environment.

Signal transmission cable require high-frequency, low-loss performance to ensure that data from ADAS sensors, in-vehicle systems, and vehicle-to-everything (V2X) communications can be transmitted in real time with high accuracy.

Main Types of Automotive cable

The Four Core Categories of Automotive cable

Depending on the application, automotive cable typically falls into four main categories:

• Power Cables: Deliver stable power for batteries, motors, and high-voltage systems.
• Signal Cables: Transmit sensor and ECU data for accurate, real-time communication.
• Communication Cable: Include CAN Bus and Ethernet cables, enabling V2X connectivity and autonomous driving.
• High-Frequency Cables: Used in ADAS, cameras, and infotainment systems for high bandwidth and low latency.

How Is the Applications of Automotive Cable in Vehicle Modules

How to choose the Right Cable for Each System?

Different vehicle systems have unique cable requirements:

• ADAS Systems: Require high-speed data cables to support radar and imaging.
• Battery Management Systems (BMS): Depend on high-temperature power and signal cables for precise energy monitoring.
• In-Vehicle Infotainment Systems: Utilize high-frequency, high-speed cables for seamless audio and video streaming.
• Powertrain Control Modules: Require high-voltage, high-current power cables to deliver consistent performance.

The Future Trends in Automotive Cable

The next step of Automotive Cable for High Voltage, High Speed, Lightweight Design.

As electric and smart vehicles become more prevalent, in-vehicle cable is evolving toward high voltage, high speed, and lightweight designs.

Modular cable harnesses and automated production are gradually replacing traditional manual bundling, enhancing consistency and reliability.

• High-voltage cables integrate safety and heat management.
• High-speed transmission cables support Gigabit-level bandwidth for advanced systems.
• Lightweight materials improve energy efficiency.

Although hidden within automotive modules, cable plays a critical role in ensuring both safety and performance. With the rise of smart and new energy vehicles, high-speed, high-efficiency, and high-reliability cables will become a core requirement.
