Installing charging infrastructure – reducing installation costs with the right planning


For businesses, having their own charging infrastructure is an important investment for their future. Alongside a company's electric vehicle fleet, environmentally conscious employees and customers can benefit in particular from having a convenient power supply for their electric vehicles.

A requirements analysis is accompanied by planning the installation process, with the aim of finding a solution tailored to the specific situation. A well thought-out and above all safe installation design with transparent costs guarantees a smart and future-oriented solution for customers. Here, Vattenfall InCharge looks at the most important factors for implementing your own cost-optimised charging solution successfully:

1. The choice of location for your charging boxes

When planning charging points for electric vehicles, it's not just a question of finding the right hardware. The choice of the future location of the charging infrastructure also plays a key role – and has a major impact on the installation costs incurred.

The simplest and most cost-effective option is a standard wall installation in an underground car park, close to an existing electrical junction box, which can supply the charging points with sufficient energy. This requires installation costs of around EUR 500 to EUR 1,000, depending on the cost of breaking through the wall and laying the electrical cables.

The basic rules is the less construction work required, the cheaper the installation and its commissioning will be.

In other words, construction work has a considerable impact on costs in particular. On average, around EUR 1,500 to EUR 2,000 in additional costs is incurred if the charging system is located outside, 10 metres away from the electrical system. The reason is simple: civil engineering works are required to ensure frost-proof installation of the power supply. In a best-case scenario, costs of between EUR 80 and EUR 100 per linear metre can be expected here on ground with loose soil. Concrete foundations also need to be poured to ensure the charging points stand securely.

Tip: Contact our experts to discuss the different location options and the impact on installation costs. The Vattenfall InCharge team is here to help ensure the installation of your charging infrastructure runs as smoothly and efficiently as possible. A personalised offer takes into account all relevant factors at your site and has a significant influence on pricing.

2. Checking the existing electrical system – does additional charge management make sense?

In addition, the condition and structure of the existing electrical installation are decisive for being able to precisely determine the work and costs that will be incurred. Our installation engineer will check how many charging points you need and whether subsequent expansion of the system may be possible. To ensure the electrical system on site is designed for the expected charging capacity, they will analyse the charging profile over a period of 48 hours and decide whether the required charging capacity can be provided.

For limited home connections, smart charge management is the solution

If home connection capacity is limited, consider taking advantage of intelligent charge management. This controls the distribution of the power available in the home network. This can prevent the need to strengthen the home connection or even upgrade the network in the surrounding area. The electrical installation engineer can also pre-programme the system when setting up the installation. This enables individual charging points to be controlled and reduces electricity costs.

3. Choice of charging box

By choosing the right hardware, customers have even more influence over the cost. State-of-the-art charging box models like the KEBA KeContact P30 charging box (from EUR 999) or the Compleo Highline BM (from EUR 4,630) are equipped with integrated residual current detection, meaning that expensive RCDs do not need to be retrofitted in a fuse box.

Tip: Choosing a high-quality charging box with integrated residual current detection saves money when carrying out the electrical installation.

4. Making use of a variety of funding opportunities and offers for charging infrastructure

Finally, let's take a look at the financing opportunities available. Our database is continually updated with companies, local authorities, private individuals, and education and research institutions that provide funding opportunities for charging infrastructure, which are available at federal, state and even city level. It is always worth checking the attractive offers available from charging providers. For example, until the end of 2020 Vattenfall InCharge is offering 33% off the KEBA KeContact P30 charging box.
