1. I am only a tenant - how do I get the electricity for charging?
Charging an electric car on rented property should always be arranged together with the landlord, as existing installations may not be designed for charging currents. The landlord's consent is required anyway for structural changes such as the installation of a power line. The landlord may even finance the installation of charging infrastructure because it increases the value of the property or real estate.
2. How fast can I charge at home?
An important factor when charging with household AC power is the power of the on-board charger in the vehicle. A maximum of 7.4 kW is theoretically possible with single-phase charging (with the appropriate supply line), but in Germany, Austria and Switzerland the power is limited to 3.7 kW in the private sector for safety reasons. All e-cars that can charge three-phase are capable of 11 kW, some even of 22 kW. An electric car with a 55 kWh battery capacity can thus be fully charged in 5 or even 2.5 hours. Charging at 22 kW requires testing by the grid operator.
3. Do I really need a wallbox?
If you want the flexibility of higher charging speeds of up to 22 kW, the safety of an installation specially made for continuous use and the convenient operation of a tidy charging station, you could not be better off than with a wallbox. The emergency charging cable that comes with the vehicle for the household socket is only an emergency solution and in no way intended for regular use.
4. Do I need an electrician?
Whether in a rental property or in owned housing - the installation of a wallbox by an expert is not only advisable, but necessary. In Germany, grid operators require a registration of the wallbox as well as a test of the peripheral device [in Austria the obligation to register varies from province to province]. The installation of the wallbox itself is not very complex, the focus is on the supply line and the protection mechanisms. The advantage of wallboxes from KEBA: An expensive type B RCD is not necessary thanks to integrated DC residual current monitoring.
5. Can I use my own solar power?
Yes, but this is not possible with every wallbox. When purchasing a wallbox, it is therefore important to ensure that the integration into a photovoltaic system is possible so that it can communicate with the energy management system of the PV system. The wallbox models of the P30 c- and x-series from KEBA meet these requirements.
6. How much does it cost to charge at home?
The cost of a kilowatt hour of a home wallbox is the same as that of normal household electricity. As a rule, refuelling at home is noticeably cheaper than at public charging stations and is therefore not only practical, but also makes economic sense. Nevertheless, prices can vary greatly from provider to provider, from country to country and depending on the electricity mix. A wallbox itself costs between 600 and 1,600 euros, depending on its features.
Charging electricity vs fueling – which is cheaper?
Due to the electric motor’s extremely high efficiency factor, electric vehicles use significantly less energy than their combustion-engine counterparts. But does that automatically make their consumption costs much cheaper? Here is a cost comparison between using electricity and the fuels petrol and diesel for your car.
1.13 with new features and improved user experience
The latest software update for KEBA’s x-series wallboxes offers both technical improvements and operating comfort. As always, it is free of charge and easy to install. So, we stay true to our principle: to keep improving our own products when they are already in use.
From the outside, a conventional combustion engine differs only marginally from its electric relative - internally, however, it differs a great deal. A different engine brings with it many new terms that require explanation. From 'A' as in 'AC' to 'F' as in 'FI circuit breaker' and many other terms, we have listed the most important technical vocabulary that an e-car driver should know.
