What are the differences between home and commercial EV AC charging stations?
The key differences between home and commercial AC charging stations lie in power, functionality, and usage scenarios: Home chargers typically use single-phase 220V (≤7kW), feature simple designs, and have lower costs (a few thousand yuan), catering only to private slow-charging needs. Commercial chargers often adopt three-phase 380V (7–22kW or higher), require multi-user support, payment systems (e.g., QR code scanning), remote management, and higher protection ratings (e.g., IP65). Their installation is more complex, costs are higher (tens of thousands of yuan), and they suit high-frequency public scenarios like parking lots and shopping malls.
What functions should a home AC EV charging station typically have?
A home AC charging station needs to provide basic functions such as safety protection (e.g., leakage prevention), smart control (e.g., scheduled charging via app), compatibility with various vehicle models, and energy-saving modes (e.g., off-peak nighttime charging).
What are the precautions for using a home AC charging station
When using a home AC charging station, please note the following points: 1) Ensure professional installation by a certified electrician and regularly inspect wiring and connectors; 2) Keep the charging environment dry and avoid use during extreme weather; 3) Prioritize off-peak nighttime charging to save on electricity costs; 4) Unplug promptly after charging to avoid prolonged idle operation; 5) Clean the charging equipment regularly and immediately stop use if abnormalities are detected. Additionally, it is recommended to keep the charging station out of children's easy reach to ensure safety.
What are the main features of AC charger for business?
Business charger is mostly equipped with metering, billing, charging, remote monitoring, higher power, robust hardware and so on to meet the requirements of reliable, revenue-generating charging.
If a AC charger fails during operation, how should this situation be handled?
When a commercial AC charger malfunctions, please follow these steps: 1) Immediately check the error code (e.g., overcurrent/communication failure) on the charging station screen or app, and suspend use; 2) Attempt an emergency reset (some devices are equipped with an emergency stop button); 3) If the issue persists, contact the maintenance team for repair (provide the station number, fault description, and time); 4) In case of dangerous situations such as leakage or smoke, immediately cut off the power and evacuate the surrounding area. The maintenance team is suggested to respond within 2 hours and provide backup stations to ensure service continuity. All faults must be recorded and analyzed to optimize future maintenance strategies.
What is AC Charging?
AC EV Charging uses standard grid electricity to power electric vehicles through an onboard charger that converts AC to DC for battery storage.
What is the main application of an AC charger?
While slower than DC fast charging, AC charger is more affordable, battery-friendly, and widely compatible with Type 1 (J1772) or Type 2 (Mennekes) connectors. It's ideal for home, work, and public charging with typical power levels of 3.7–22 kW (Level 2) or up to 43 kW (three-phase). Best suited for overnight or extended charging sessions.
What should I do if the indicator is power off?
Check whether the input or output voltage remains, otherwise, replace the failure module.
When the ambient temperature is over the operation temperature, how does the module work?
Usually the power derates from 55 °C, and it will derate to 0w when the ambient temperature reaches 75°C to protect the charging system and EVs.
What is the main cooling method?
Considering most application scenarios, forced air-cooling is cost-effective and widely used. The high protection independent air-duct cooling can adapt to much harsh environments to meet most requirements from customers and end users.
