EV-Heimladegeräte (Ladestationen)

Choose based on your electrical supply and your vehicle's onboard charger. A 7kW single-phase charger is sufficient to fully charge most EVs overnight. 11kW and 22kW three-phase chargers reduce charging time, but only if your vehicle supports that power. Many EVs are limited to 11kW AC charging. If you have a single-phase supply, 7.4kW is the maximum charging power available. 

7kW chargers run on a standard single-phase supply, which most homes have. 11kW and 22kW chargers require a 400V three-phase connection. A certified electrician can confirm what type of electrical supply your property has and whether an upgrade is needed before you choose a charging station. 

Tethered charging stations have a built-in cable, so charging is as simple as plugging it into your vehicle. Socket charging stations do not include a cable, giving you the flexibility to use different cable lengths, but requiring you to buy and store a separate Type 2 cable. Tethered stations are more convenient for a single vehicle, while socket stations are better suited to shared or multi-vehicle use. 

Dynamic load balancing prevents your charger from overloading your home's electrical supply when other appliances are running. OCPP allows the charging station to connect to charging management platforms. RFID provides access control, while app or Wi-Fi connectivity enables charging schedules around off-peak tariffs and remote monitoring. For home use, prioritise dynamic load balancing and app control. 

Yes. All wallboxes must be installed by a certified electrician, who mounts the unit, connects it to your electrical supply, installs circuit protection and RCD safety devices, and configures the smart features. Professional installation is also usually required to maintain the manufacturer's warranty and qualify for any government grant. 

Many models qualify when purchased with the required accessories, such as a compatible smart meter. Grant rules and amounts vary by country, so check the current eligibility criteria for your national grant scheme before ordering.
