Megawatt Charging Ready | Liquid-Cooled Charging System for CCS,NACS & MCS

Powering High-Power E-Mobility Across Global Standards


As electric mobility accelerates across railway depots, commercial vehicles, port operations and marine transport, one challenge remains unchanged: delivering ultra-fast, high-power charging across different international standards.

To support this transition, Yonggui Electric provides a unified solution compatible with CCS, NACS and MCS — three of the most important global charging standards discussed within the CharIN community.

Why Liquid Cooling Matters for Megawatt Charging

High-current charging (500A, 1,000A and up to 1,500A) generates extreme heat that cannot be safely controlled by air cooling alone. Liquid cooling is now the essential technology to enable next-generation megawatt charging, offering:

  • Effective thermal management and lower temperature rise
  • Continuous high-power or megawatt-level output
  • Enhanced charging speed, safety and system stability
  • Reliability in harsh ambient environments (dust, humidity, salt spray)

What Makes Our System Different

We do more than supply charging connectors — we offer a scalable, modular system:

  • Liquid-cooled charging connector + vehicle inlet (CCS / NACS / MCS-ready)
  • Integrated cooling loop: radiator, pump, fan, reservoir
  • Smart monitoring of temperature, pressure and coolant flow
  • Internal communication via CAN / RS485
  • Verified durability: IP67, salt spray, high-humidity testing, CE / UL / TÜV / CB / UKCA
  • Manufacturing in both China & Thailand for global delivery
(System configuration can be adapted to OEM requirements.)

Why Leading OEMs Trust Yonggui

With 50+ years of expertise in high-reliability connectors, Yonggui Electric supplies global projects in:

  • Rail electrification
  • Commercial EV platforms
  • Port and industrial vehicle charging

We deliver proven, scalable liquid-cooled solutions that power the future of high-power charging.
