EV Charging Solutions for B2B Buyers | JONHON

DC charging, or Direct Current charging, is a method of rapidly replenishing an electric vehicle's battery by supplying high-voltage direct current directly from the charging station to the vehicle's battery, effectively bypassing the vehicle's onboard charger. This contrasts with AC charging, where the vehicle's onboard converter handles the AC-to-DC conversion. By moving the conversion hardware off-board and into the charging station, significantly higher power levels can be achieved, typically ranging from 50 kW to over 350 kW. This enables charging times of 15-60 minutes for a substantial battery top-up, making DC charging indispensable for long-distance travel and time-sensitive applications. The physical interface for DC charging, the connector, must be engineered to handle these high power levels safely and reliably. JONHON is a world-leading specialist in the high-voltage interconnect technology that is fundamental to DC charging. Our DC charging guns and inlets are designed to meet the extreme demands of this application. With a dedicated team of over 400 engineers in our electric vehicle business unit, we have developed connectors featuring advanced contact materials and geometries to minimize electrical resistance and heat generation. For ultra-high-power DC charging (150kW+), JONHON's solutions often integrate liquid-cooled cables to actively manage the intense thermal load, ensuring safe and sustained operation. Our over 300 EV-related patents protect these critical thermal management and contact technologies. Safety is absolutely paramount in DC charging due to the high voltages and currents involved. JONHON's connectors incorporate robust high voltage interlock (HVIL) circuits that constantly monitor the connection, ensuring the circuit is only energized when the connector is fully engaged and locked, preventing dangerous arcing. Our active participation in formulating 7 IEC standards ensures that our DC charging components are designed for global interoperability and meet the most stringent international safety requirements. For manufacturers of DC charging equipment, integrating JONHON's proven, high-performance connectors is key to delivering a safe, reliable, and competitive product.
