EV Charging Solutions for B2B Buyers | JONHON

The car charging voltage is a critical specification that defines the electrical potential difference at which power is transferred from the charging station to an electric vehicle. It is a primary factor determining the rate of charge and is governed by the type of charging system and the vehicle's own battery architecture. JONHON, as a specialist in high-voltage interconnect technology, engineers its products to perform reliably across the full spectrum of car charging voltages used globally. For Alternating Current (AC) charging, which is common for home and workplace charging, the voltage is typically standard mains voltage. In North America, this is often 120V (Level 1) or 208-240V (Level 2). In many other parts of the world, Level 2 AC charging operates at 230V single-phase or 400V three-phase. The vehicle's onboard charger converts this AC power to Direct Current (DC) to charge the battery. For Direct Current (DC) fast charging, the charging station itself converts AC grid power to DC and delivers it directly to the vehicle, bypassing the onboard charger. DC fast charging voltages vary widely, typically ranging from 200V to 1000V, with newer ultra-fast systems designed for 800V and even higher voltage battery packs to minimize charging time. Handling these high voltages safely and efficiently demands exceptional engineering in connector design. JONHON's charging guns and inlets incorporate advanced insulation materials, optimized contact geometries, and high voltage interlock (HVIL) circuits to ensure safe operation and prevent arcing or accidental disconnection under load. Our team of over 400 EV-dedicated engineers leverages our extensive patent portfolio, which includes over 300 EV-related patents, to continuously improve the performance and safety of our components across all voltage levels. Furthermore, our involvement in setting IEC standards helps ensure that our products are designed for global compatibility and safety.
