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.
