A 350kW charger represents the leading edge of widely deployed DC fast charging technology for electric vehicles. It is an ultra-fast charging station capable of delivering immense power, enabling compatible EVs, particularly those with 800V battery architectures, to add hundreds of kilometers of range in just 15-20 minutes. This power level, which involves currents potentially exceeding 500 Amperes at up to 1000 Volts DC, places extraordinary demands on every part of the charging system, especially the physical connector and cable that the user handles. JONHON is a specialized manufacturer at the forefront of engineering the high-performance interconnect solutions required for 350kW charging. Our charging guns and cables for this power class are not simple extensions of lower-power designs; they are sophisticated electromechanical systems. JONHON's engineering team, comprising over 400 specialists in our electric vehicle business unit, has developed connectors that incorporate advanced liquid cooling. A coolant circulates through the cable and connector, actively removing the intense heat generated by the high current, keeping the cable flexible and safe to touch while ensuring the electrical contacts operate within their optimal temperature range. This technology is protected by our extensive portfolio of over 300 EV-related patents. Safety at this power level is absolutely critical. JONHON's 350kW connectors integrate multiple safety features, including a robust high voltage interlock (HVIL) system that constantly monitors the connection and ensures the high-voltage circuit is only active when the gun is fully seated and locked. This prevents arcing and protects the user from electrical hazards. Furthermore, JONHON's active involvement in formulating 7 IEC standards ensures that our ultra-high-power components are designed for global interoperability and meet the world's most stringent safety and performance requirements. The durability required for a 350kW charger in a public setting is also immense, and our connectors are engineered to withstand tens of thousands of high-stress charging cycles. For manufacturers developing 350kW charging stations, integrating JONHON's proven, liquid-cooled connector technology is essential for delivering a safe, reliable, and high-performance product.
