Green Ocean's EV charger development incorporates precision thermal management using extruded aluminum heatsinks and temperature-compensated charging algorithms. Our 22kW AC commercial stations feature dual Type 1/Type 2 connectors with automatic detection, supporting simultaneous charging through intelligent power sharing. The DC portfolio includes 160kW cabinet systems with active power factor correction (≥0.99) and CHAdeMO/CCS Combo 2 compatibility. During deployment at Thai shopping malls, our cloud-managed charging systems demonstrated 99.3% uptime while processing 12,000+ monthly sessions. Hardware reliability stems from industrial-grade components rated for 100,000 operational hours, with cybersecurity measures including TLS 1.3 encryption and PCI DSS-compliant payment systems. The integrated revenue management platform supports multi-currency transactions and dynamic pricing models.
