Charging company vehicles at your private charging station

Charging the company car at home – this is how the billing works

Electric cars are increasingly the first choice for a company’s vehicle fleet. To make the best use of them, drivers should charge them at home – the electric vehicle can park overnight and thus refuel in the most economic way. To pass on that part of the electricity bill to the employer, there are various options.

Charge at home with a Wallbox only

First, a note about the safety of a private domestic electrical system: While pure battery-electric vehicles (BEV) or plug-in hybrids (PHEV) often come with a charging cable for earthed domestic sockets, this charging method should be avoided whenever possible. It is a stopgap solution. Conversely, a properly installed wallbox is built for continuous use and higher charging rates. And there are many advantages that come with it.

The radical option: your own electricity meter

Arguably the most time-consuming method of passing on electricity costs incurred by your company car is to install an additional electricity meter in your own distribution board. Here, it is as if the charging station had its own power supply—like a separate flat whose supply is registered to the employer. But this causes additional costs, due to both the extra installa-tion work and the material used. Moreover, the charging rate becomes more expensive per kWh, as there are additional power network access charges.

The intelligent option: a wallbox with an integrated electricity meter

Wallboxes like the P30 models of KEBA’s c-series or x-series count the electricity that flows through them into the battery. The total amount of kilowatt hours is clearly visible on the case display, but can also be retrieved on the web interface of these connected wallboxes (e.g., via Wi-Fi). Thus, the simplest solution is to send a monthly or quarterly invoice to the employer for the power consumed at the agreed kWh price based on the actual electricity costs incurred. You don't even have to document the consumption yourself - the latest KEBA software automatically sends monthly reports by email.

MID-certified meter for reliable billing - even at home

Wallboxes with MID-certified energy meters ensure the highest precision in billing. This meter is calibrated and generates its own data record for each charging session, which can be viewed in the charging station's web interface. This means that the charging data is beyond any doubt. All KEBA wall boxes of the c- and x-series are optionally available with MID meters.

Especially for Germany, the charging stations are also available as Mess- und Eichrecht conform, whereby a signed data record is automatically generated in the device for each charging session and stored in the long-term memory. This gives users the opportunity to check the authenticity and correctness of their charging processes thanks to a transparency software.

Pass on costs to employer: even with multiple private users

If there is more than one electric vehicle in your home or in a shared garage, the precise billing of costs incurred by charging the company vehicle is also not a problem. The solution: user allocation via RFID. KEBA wallboxes equipped with this feature register who is currently charging and thus allow for a transparent breakdown of the charging sessions. Moreover, this feature is also perfectly suited for private users who wish to split costs in the shared charging infrastructure.

Is it worth having a wallbox for my plug-in hybrid (PHEV)?

With modern plug-in hybrids, distances of up to 90 kilometers can be achieved purely electrically. That is usually enough for the commute to work or other everyday journeys. All the same, the batteries of these PHEVs are significantly smaller than those of purely battery-electric vehicles (BEVs). So, is a household socket sufficient for daily charging or does it still make sense to have a wallbox?

"Urcharge" project examines crucial questions about the viability of e-mobility for everyday use

One of the largest and longest electric mobility field tests in Austrian history starts tomorrow. For the project "Urcharge" (Urban Charging) 51 households in a Linz residential complex will be exchanging their fuel car for an electric car including their own KEBA charging station, which is integrated into the Linz AG charging solution "WallBOX CitySolution". It will provide answers to fundamental questions about what infrastructure and charging behaviour is needed in order to make the day-to-day use of e-mobility a decisive environmental protection factor in urban areas, even for densely populated areas. The start of the project had been postponed due to Corona - now the project gets underway.

ÖkoFEN charges corporate fleet with KEBA charging stations

The pellet heating systems specialist ÖkoFEN, which is located in Niederkappel in the region of Mühlviertel in upper Austria, has counted on KEBA since 2013 when it comes to the controlling of their biomass boilers. Over the last few years, ÖkoFEN has developed into a supplier for comprehensive energy solutions and has now, for the most part, converted their vehicle fleet to electric cars. The vehicle fleet is of course charged with KEBA’s charging station. (Picture reference: ÖkoFEN)
