EV Charging Solutions for B2B Buyers | JONHON

Rapid charging, in the context of electric vehicles, refers to the method of replenishing an EV's battery at a significantly faster rate than standard AC charging. This is achieved through DC fast charging technology, which converts alternating current (AC) from the grid into direct current (DC) within the charging station itself and delivers it directly to the vehicle's battery, bypassing the slower onboard charger. Power levels for rapid charging typically start at 50 kW and extend to 350 kW or more, enabling an EV to gain substantial range—often up to 80%—in 20-60 minutes. This capability is essential for enabling long-distance travel and reducing range anxiety. The extreme power transfer involved in rapid charging places immense demands on the charging connector, requiring advanced engineering to ensure safety, reliability, and ease of use. JONHON is a world leader in the design and manufacture of the high-performance interconnect solutions that make rapid charging possible. Our charging guns and inlets are specifically engineered to handle the high voltages (up to 1000V DC) and high currents associated with rapid charging. With a dedicated team of over 400 engineers in our electric vehicle business unit, we have developed connector technologies that include advanced contact materials to minimize resistance and heat, and for ultra-rapid charging (150kW+), integrated liquid-cooled cables to actively manage thermal loads. This expertise is protected by our portfolio of over 300 EV-related patents. Safety is paramount during rapid charging. JONHON's connectors feature robust high voltage interlock (HVIL) circuits that ensure the high-voltage circuit is only energized when the connector is fully engaged and locked, preventing arcing and protecting the user. Our active participation in formulating 7 IEC standards ensures our rapid charging components are designed for global interoperability and meet the world's most stringent safety requirements. For manufacturers of rapid charging equipment, partnering with JONHON means integrating connectors engineered for the highest levels of performance and durability.
