What are AC EV chargers?
AC EV chargers, often called wallboxes, supply alternating current to an electric vehicle, and the car’s onboard charger converts it to direct current for the battery. AC charging costs less to install than DC fast charging and suits places where cars stay parked for hours, such as homes, offices, apartments and hotels. Raivens designs and builds AC EV chargers in-house, from 3.3 kW single-phase units to 22 kW three-phase models, in wall-mount and pedestal versions.
Power options
| Power | Supply | Energy per hour at full output | Typical setting |
|---|---|---|---|
| 3.3 kW | Single-phase | Up to 3.3 kWh | Homes, overnight parking |
| 7.4 kW | Single-phase | Up to 7.4 kWh | Homes, offices, apartments |
| 11 kW | Three-phase | Up to 11 kWh | Offices, apartment car parks, hotels |
| 22 kW | Three-phase | Up to 22 kWh | Hotels, workplaces, retail and fleet parking |
Single-phase options span 3.3 to 7.4 kW. The vehicle’s onboard charger sets the highest AC rate it accepts, so a car limited to 7.4 kW charges at 7.4 kW even on a 22 kW wallbox. Match the charger to the vehicles you expect, with room for the next ones.
How to choose
Three questions settle the choice:
- What supply do you have? Single-phase sites use 3.3 to 7.4 kW models. Three-phase sites can add 11 or 22 kW.
- Who will charge? A private home rarely needs access control. Shared sites need RFID or app authorization.
- How many chargers? Two or more units on one connection usually call for load management.
Built for homes, offices, apartments and hotels
- Homes. A 3.3 or 7.4 kW wall-mount unit charges overnight, and schedules move charging into off-peak tariff hours.
- Offices. Staff charge during the workday, and RFID cards or the app decide who can plug in.
- Apartments. Shared car parks need access control and fair cost sharing. RFID or app control ties each session to a resident, and smart electricity meters can bill the energy per user.
- Hotels. Pedestal chargers at 11 or 22 kW let guests charge overnight, an amenity for guests who drive electric.
Key capabilities
- Type 2, socket or tethered. An untethered socket suits shared sites where drivers bring their own cable. A tethered cable is the easy choice at home.
- Wi-Fi, 4G or Ethernet. Chargers stay online through the network the site already has, for app control and remote management.
- Scheduling. Charging windows can follow off-peak tariffs or quiet building hours.
- Load management. When several chargers share one connection, load management keeps total demand within the available capacity. This can delay or avoid a costly supply upgrade.
Installation and support
Raivens supports the site check, installation and commissioning, and provides after-sales support from the same in-house team that designs the hardware and firmware. Compliance documentation per model is available on request.
