Jonhon’s EV chargers are renowned for their exceptional reliability, built on robust engineering and rigorous testing. The chargers feature a mean time between failures (MTBF) exceeding 100,000 hours, achieved through redundant power supplies and fault-tolerant designs. Each charger undergoes 48-hour burn-in testing at full load, temperature cycling (-25°C to +70°C), and vibration testing (5-500Hz) to simulate real-world conditions. Jonhon’s proprietary diagnostic system continuously monitors 200+ parameters, detecting anomalies and triggering proactive maintenance alerts. The company’s after-sales service includes annual preventive maintenance programs, ensuring chargers operate at peak performance for 10+ years. This reliability has made Jonhon chargers the preferred choice for mission-critical applications like electric bus depots and highway charging networks.
