Seize the night: how companies can encourage charging at home

Diese Förderungen gibt es

The home wallbox is perhaps THE key to successful fleet electrification. But for drivers to be able to charge their cars at home, they need support from fleet operators. We explain the best way to achieve this in part two of our topic special on the charging infrastructure.

Power consumption in kWh/100 km: combined 17.1; CO₂ emissions in g/km: 0; efficiency class: A+++. Vehicle image shows special equipment.

Your own fuel pump without the smell of petrol – and always free and available for its owner: having a wallbox in your own parking space at home is a key element of the mobile transformation. In a perfectly coordinated fleet, vehicles connect to the grid wherever they remain for longer.  That might be on the company premises or also at the company car driver’s home.

After all, even the most active need to rest some time. And not only does it do them good, but also the battery in their electric vehicle. Nighttime is the peak charging time in reality. Even someone who only arrives home at 8:00 pm and has to leave again on another business trip at 6:15 am the next morning can recharge an Audi e-tron 55 (power consumption in kWh/100 km, combined: 24.3-22.0 (NEDC), 26.1-22.2 (WLTP); CO₂ Emissions in g/km: 0; efficiency class: A+++) at an 11 kW Audi Wallbox pro¹⁾ to a range of up to 441 km within a period of nine hours and 15 minutes²⁾³⁾.


Renters can also assert their claim
The greatest convenience is naturally enjoyed by fleet users who live in their own house and can therefore position the wallbox on the garage or house wall without objections from third parties. Yet owners in owner communities or even renters with their own parking space have good opportunities and arguments for charging at home. A legal right to the installation of a wallbox exists in principle in Germany since 1 December 2020.  A home check needs to be carried out by the relevant provider in any event in order to determine the optimum charging solution in each individual case.

Conveniently charging your company car outside your door – and not only for home owners.

One solution for fleet managers without doubt when choosing a model for the fleet user is a connective wallbox with energy meter and authorisation option – such as the Elli Charger Pro. This allows billing to be arranged via the company backend. After all, charging at home naturally only becomes attractive for the fleet user when the employer reimburses the costs. The company, in turn, then benefits on the one hand from lower electricity costs than at public charging points; on the other hand, the charging infrastructure at the company location is not overburdened and may possibly even be scaled back.

The home wallbox is a winner all round
These advantages usually weigh so heavily that companies are increasingly more inclined to also assist their company car drivers with the costs of purchasing and installing a wallbox. Various models are possible, such as gifting as part of salary as a non-cash benefit, provision as a subsidy exempt of social security contributions, transfer/loan as a salary inflow as well as leasing with subsequent transfer (where the residual value is likewise in addition to wages).  

Such support on the part of the employer will be particularly in demand in the coming months, since the highly popular KfW subsidy for domestic wallboxes expired at the end of October 2021; applications are no longer being accepted for the subsidy (440).⁴⁾ However, this is unlikely to halt the rapid growth in home charging networks – ultimately, having a “fuel pump” on the doorstep is just too convenient ...


Which subsidies are available for electric vehicles and the charging infrastructure?

This question is answered by the online subsidy information service offered by febis Service GmbH on behalf of Volkswagen Commercial Vehicles. Just a few details are needed to get a complete overview of all subsidies available in Germany from the federal government, states, municipalities and energy suppliers. The possibility of combining the available funding is not checked in the process. The relevant subsidy guidelines apply in each case; they can be retrieved as a summary of the information.

²⁾The charging period of the battery can vary depending on a number of factors such as the ambient temperature, the use of other country-specific connectors and use of the preconditioning function (e.g. remote-controlled air conditioning of the vehicle). Use of household connectors limits the charging efficiency of the e-tron charging system.
³⁾The maximum value requires efficiency driving mode with air conditioning and heating turned off. Another requirement is use in city traffic at temperatures above 5°C and with 19 inch standard tyres.

The specified fuel consumption and emission data have been determined according to the measurement procedures prescribed by law. Since 1st September 2017, certain new vehicles are already being type-approved according to the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure for measuring fuel consumption and CO2 emissions. Starting on September 1st 2018, the New European Driving Cycle (NEDC) will be replaced by the WLTP in stages. Owing to the more realistic test conditions, the fuel consumption and CO2 emissions measured according to the WLTP will, in many cases, be higher than those measured according to the NEDC. Therefore, the usage of CO2 emission values measured according to WLTP for vehicle taxation from 1st September 2018 on can cause changes in this regards as well. For further information on the differences between the WLTP and NEDC, please visit www.volkswagen.de/wltp or www.audi.de/wltp.

We are currently still required by law to state the NEDC figures. In the case of new vehicles which have been type-approved according to the WLTP, the NEDC figures are derived from the WLTP data. It is possible to specify the WLTP figures voluntarily in addition until such time as this is required by law. In cases where the NEDC figures are specified as value ranges, these do not refer to a particular individual vehicle and do not constitute part of the sales offering. They are intended exclusively as a means of comparison between different vehicle types. Additional equipment and accessories (e.g. add-on parts, different tire formats, etc.) may change the relevant vehicle parameters, such as weight, rolling resistance and aerodynamics, and, in conjunction with weather and traffic conditions and individual driving style, may affect fuel consumption, electrical power consumption, CO2 emissions and the performance figures for the vehicle.

Further information on official fuel consumption figures and the official specific CO2 emissions of new passenger cars can be found in the “Guide on the fuel economy, CO2 emissions and power consumption of new passenger car models”, which is available free of charge at all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, D-73760 Ostfildern, Germany and at www.dat.de.
