EV Charging Solutions for B2B Buyers | JONHON

An EV power charging station, more formally known as Electric Vehicle Supply Equipment (EVSE), is the infrastructure unit that supplies electrical energy for recharging electric vehicles. The term "power" in this context emphasizes its primary function: delivering significant electrical power from the grid to the vehicle's battery. These stations range from AC units for home and workplace use to DC fast chargers for public and commercial applications. The power level, measured in kilowatts (kW), directly dictates charging speed. A key engineering challenge is safely and reliably transferring this power, especially at higher levels, through the user-connected interface. JONHON is a premier global specialist in the technology that enables this power transfer: the high-voltage interconnect system, comprising the charging gun, cable, and vehicle inlet. For any EV power charging station, the connector is the most stressed and safety-critical component. JONHON's engineering team, with over 400 engineers dedicated to our electric vehicle business unit, designs these components to handle the full spectrum of power levels. For AC stations, this means robust, ergonomic connectors for daily use. For high-power DC stations (50kW-350kW), it requires advanced engineering to manage heat and ensure absolute safety. Our connectors utilize precision contact systems to minimize resistance and heat, and for ultra-high power, incorporate liquid-cooled cables, technologies protected by over 300 EV-related patents. Safety is paramount when dealing with high power. JONHON's charging guns integrate high voltage interlock (HVIL) circuits that ensure power is only delivered when a secure, locked connection is made, preventing arcing. Our deep involvement in formulating 7 IEC standards ensures our power transfer components meet the rigorous global requirements for safety and interoperability. For manufacturers of EV power charging stations, choosing JONHON's proven interconnect solutions means building on a foundation of reliability and performance that ensures long-term station uptime and user trust.
