Frequently Asked Questions
What is Dynamic Load Balancing (DLB) in EV charging stations?
Dynamic Load Balancing (DLB) is a feature that automatically adjusts the charging power distributed among multiple EV chargers based on real-time grid capacity. This prevents overloading the electrical circuit while ensuring all connected vehicles are charged efficiently and safely.
What is the difference between 1-phase and 3-phase EV charging?
1-phase charging supports power output from 1.3kW to 7.4kW, suitable for residential or light commercial use. 3-phase charging delivers higher power from 4.1kW to 22kW, ideal for commercial locations where faster charging is required. The appropriate choice depends on your vehicle's onboard charger and local electrical infrastructure.
What safety protections are built into these EV charging stations?
These chargers include comprehensive safety features: overvoltage and undervoltage protection, overload and short circuit protection, grounding and lightning protection, emergency stop, leakage protection with built-in Type B RCD, over-temperature sensing, and adhesion detection — all meeting IEC62196 standards with IP54 weatherproof protection.
Can these charging stations be monitored and managed remotely?
Yes. The smart version supports multiple communication methods including Ethernet, 4G, WiFi, and Bluetooth, along with a dedicated mobile App. This allows remote monitoring, control, charging reservations, and integration with vehicle management systems via Open Charge Point Protocol (OCPP).
What payment and charging modes are supported?
The charging stations support multiple modes including plug-and-play, scheduled charging, and automatic stop when fully charged. Payment can be made via RFID card swipe or QR code scanning, making them convenient for both private and commercial deployment.
What warranty and operating conditions do these EV chargers come with?
All units come with a 3-year manufacturer warranty. They are rated to operate in temperatures from −25°C to +50°C, humidity up to 95% (frost-free), and at altitudes below 2,000 meters. The forced air cooling system keeps noise levels at or below 40 dB during operation.
