SINBON Electronics Co., Ltd., a prominent electronics system integrator, is announcing that its proprietary liquid cooling system has obtained the first UL safety certification for liquid cooling systems of EV charging stations in the world. This is significant because charging times continue to be a barrier to EV adoption.
“As extreme fast charging (XFC) becomes the future of the EV industry, advanced liquid cooling systems like SINBON’s are reducing charging times, improving energy efficiency, ensuring longevity of charging equipment,” commented Hanson Zhou, R&D Manager at SINBON. “This milestone demonstrates how SINBON’s technological innovation and commitment to excellence continue to expand possibilities for the EV industry.”
The potential of liquid cooling for EV charging stations
As EV adoption accelerates, the demand for faster, more efficient charging solutions is growing. Liquid cooling is emerging as a critical enabler of extreme fast charging (XFC), which greatly reduces charging times, making electrification more viable for both consumers and commercial fleets.
Liquid cooling system like SINBON’s addresses several key industry challenges:
- Reduced charging times: By enabling higher power delivery, liquid cooling system significantly shortens EV charging durations — ideal for EV drivers and essential for commercial applications like electrified long-haul freight trucks.
- Enhanced energy efficiency: The system minimizes heat buildup in cables, reducing energy loss and improving overall system performance.
- Lighter, more flexible cables: Liquid cooling allows for thinner, more manageable cables without compromising safety or performance.
- Thermal stability: This system also maintains optimal temperatures, ensuring consistent power delivery and safe operation.
A milestone in safety and innovation
SINBON recently secured UL certification, marking a significant achievement for the company’s EV solutions, affirming the safety, reliability, and performance of its liquid cooling system. A globally recognized safety authority, UL rigorously scrutinizes products across design, materials, manufacturing, and performance. This certification also illustrates SINBON’s leadership in R&D and its commitment to setting new industry standards.
Pushing the boundaries of charging power
SINBON’s charging solutions powered by its cutting-edge liquid cooling system can deliver up to 1 Megawatt (MW; 1000A at 1000V), enabling ultra-fast charging scenarios:
- 6-minute charge: At 1 MW power load, a 100 kWh battery can be charged in just six minutes.
- Cross-standard support: SINBON works with all major charging standards, including NACS DC, CCS1, CCS2, and MCS.
SINBON’s advantages in liquid cooling
The company’s liquid cooling system is engineered for versatility and durability:
- Innovative split design: Unlike traditional integrated designs, SINBON’s split design enhances flexibility and maintenance
- Extreme environmental resistance: Operates reliably in harsh conditions, including temperatures as low as -40°C—ideal for rugged EV deployments
- Rapid, even heat dissipation: Effectively removes heat from charging components, maintaining system integrity
- Rigorous testing: Extensively tested, particularly with SINBON’s own charging cables to ensure seamless performance and integration
- Support for multiple coolants: Compatible with both water-based and oil-based coolants
