Frequently Asked Questions
What is the difference between 7kW and 22kW AC chargers?
The 7kW charger uses a single-phase power supply and is ideal for residential use, while the 22kW charger uses a three-phase supply, providing faster charging for vehicles compatible with higher AC inputs.
Can this charging pile be installed outdoors?
Yes, the unit features an IP55 protection grade, making it rainproof and dustproof, suitable for both indoor and outdoor environments.
Does the charger support smart connectivity?
Yes, it supports Ethernet and 4G communication protocols, as well as the OCPP 1.6 standard for intelligent management and monitoring.
What safety protections are built into the device?
It includes comprehensive protection against over-voltage, under-voltage, over-current, short circuits, leakage (including DC 6mA RCD), over-temperature, and lightning strikes.
How is the charging process started?
Charging can be initiated via RFID card reading, or through scheduled appointments via the intelligent interface. An emergency stop switch is also provided for immediate manual cutoff.
