Jonhon’s EV charging connector quality assurance is rooted in a rigorous 12-stage control process, ensuring premium performance. The company’s ISO 9001-certified facilities use automated production lines for precision manufacturing, with each connector undergoing 100% functional testing. Key checks include contact resistance measurement (≤5mΩ), insulation resistance tests (≥100MΩ), and dielectric withstand voltage (1,000V AC for 1 minute). Jonhon’s military-grade component sourcing—such as high-reliability capacitors and temperature-resistant cables—enhances durability. The connectors are also subjected to environmental testing: thermal cycling (-40°C to +85°C), vibration (5-500Hz), and humidity (95% RH for 1,000 hours). Each product is traceable via unique QR codes, with comprehensive quality reports provided, ensuring full accountability and compliance with international standards (IEC 62196, UL 2251).
