EV Charging Solutions for B2B Buyers | JONHON

EVSE, which stands for Electric Vehicle Supply Equipment, is the formal technical term for the infrastructure that supplies electrical energy to recharge electric vehicles. Commonly referred to as charging stations, EVSE units are the critical link between the electrical grid and the vehicle. Their primary function is to safely deliver power, but they also incorporate crucial control and communication functions, such as ensuring the vehicle is properly connected, managing the flow of electricity, and providing ground fault protection. While the EVSE cabinet contains the control electronics and contactors, the most user-facing and mechanically stressed component is the charging cable and connector assembly. JONHON is a premier global manufacturer specializing in these essential high-voltage interconnect components for EVSE. The performance, safety, and longevity of any EVSE unit are significantly determined by the quality of its charging gun. JONHON's engineering team, with over 400 engineers dedicated to our electric vehicle business unit, designs these connectors to withstand the rigors of years of use, including thousands of plug-unplug cycles, exposure to weather, and cable strain. Our extensive patent portfolio, which includes over 300 EV-related patents, protects innovations in contact technology, sealing, and ergonomic design that enhance the reliability and user experience of EVSE. Safety is paramount in all EVSE equipment. JONHON's charging guns integrate high voltage interlock (HVIL) circuits that communicate with the EVSE's controller, ensuring that power is only delivered to the pins when the connector is fully engaged and locked into the vehicle inlet. This prevents arcing and protects the user. Furthermore, JONHON's active participation in formulating 7 IEC standards ensures our EVSE components are designed to meet the strictest global requirements for safety and interoperability, allowing them to function seamlessly with all compliant electric vehicles. For manufacturers of EVSE, choosing JONHON as a partner means building your charging station on a foundation of proven, high-quality interconnect technology.
