Liquid Cooling: The Key to 500kW+ Charging with CCS Cables

The Challenge of Charging Speed: The Cable Bottleneck in the High-Power Era

As electric vehicles (EVs) become more common, consumer demand for faster charging is growing. From initial home AC slow charging to public DC fast charging, power has surged from 100kW to much higher levels. However, increasing power isn't easy. According to the principles of physics, current flowing through a conductor generates heat; the higher the current, the more heat. When charging power reaches several hundred kilowatts, traditional CCS (Combined Charging System) cables can't dissipate heat effectively. This leads to overheating risks, severely compromising charging safety and efficiency, and becoming a critical bottleneck that limits charging speed.

The Revolution of Liquid Cooling: A Dual Guarantee of Safety and Efficiency

To overcome this bottleneck, liquid cooling technology emerged, fundamentally changing the design and performance of CCS charging cables.

The Internal Secrets of Liquid-Cooled Cables

Compared to traditional cables, liquid-cooled CCS charging cables feature a revolutionary design. They are not just simple wires but a precise system that integrates multiple functions.

Internal Structure: From "Copper Wire" to "Fluid Cooling System"

High-Conductivity Conductors: The core of the cable remains a highly efficient conductor, such as copper-clad steel/tinned copper-clad steel or copper-clad aluminum/tinned copper-clad aluminum composite materials. These materials not only offer excellent conductivity but also ensure the cable's strength and manage its weight.
Integrated Cooling Channels: The most significant innovation is the inclusion of dedicated cooling channels within the cable. During high-current charging, a cooling fluid circulates in a closed-loop system, drawing heat away from the conductors and dissipating it through an external radiator.
Smart Temperature Sensors: For precise control and monitoring, the cables typically integrate temperature sensors. If the cable temperature exceeds a safe threshold, the system automatically reduces the charging power or even stops charging, ensuring absolute safety.

The Disruptive Impact of Liquid Cooling Technology

To more intuitively understand the changes brought by liquid cooling technology, here is a comparison of the parameters of traditional and liquid-cooled cables:

Parameter	Traditional CCS Charging Cable	Liquid-Cooled CCS Charging Cable
Charging Power	Charging power is limited, unable to dissipate heat effectively, and prone to overheating.	Can support charging at 350kW, 500kW, or even higher power.
Charging Speed	Charging speed is relatively slow due to power limitations.	Charging is faster, able to fully charge an EV in just over ten minutes.
Cooling Method	Relies on natural heat dissipation, which is inefficient.	Internally integrates dedicated cooling channels for efficient heat dissipation through circulating coolant.
Core Material	Not detailed, but implied to be a conventional conductor.	Core materials are composite materials such as copper-clad steel/tinned copper-clad steel and copper-clad aluminum/tinned copper-clad aluminum, combined with liquid cooling technology.
Safety and Reliability	Presents an overheating risk, which can affect charging safety and efficiency.	Through efficient heat dissipation and real-time temperature monitoring, overheating is effectively prevented, leading to higher safety.
User Experience	Charging speed is limited, which may increase waiting time.	Charging is fast, which can solve "range anxiety," but the cable may be thicker and heavier.

1. Enabling Ultra-High-Power Charging

The application of liquid cooling technology has allowed CCS charging power to easily surpass the 100kW threshold, reaching 350kW, 500kW, and even higher. This means EVs can be fully charged in just over ten minutes, significantly improving the user experience and resolving "range anxiety."

2. Enhancing Charging Safety and Reliability

Through efficient heat dissipation and real-time temperature monitoring, liquid-cooled cables effectively prevent overheating, eliminating safety hazards like fires. This protects not only the vehicle and charging station but also provides users with greater peace of mind.

3. Optimizing the User Experience

Although liquid-cooled cables can be thicker and heavier, the technology integrated within them makes their use smarter and more reliable. With ongoing advancements, the flexibility and weight of these cables are continuously being optimized, promising an even more convenient charging experience in the future.

The High-Speed Path to the Future

From the conventional 100kW to today's 500kW+, liquid cooling technology is undoubtedly the core driver of the CCS charging cable's evolution. It has not only solved the heat dissipation challenges of high-power charging but has also redefined how electric vehicles are charged. Innovative materials from companies like Changzhou Yuzisenhan Electronic Co., Ltd. provide a solid foundation for this technological revolution, collectively painting a picture of a faster, safer, and more efficient electric mobility future.
