Consider all factors
Urs Pfister never answers these questions in exactly the same way because everything depends on the individual conditions at the site. Starting with the fundamentally available energy that the local electricity plant can deliver to the quality of the electrical cables in the building to the possible potential of producing electricity for the vehicles using the photovoltaic system on the roof at the site. "You have to take all factors into account in order to get the most out of it and to avoid any stumbling blocks," emphasises Urs Pfister, and names as an example of possible complications, among other things, inexperienced charging infrastructure providers. "For many, it is new territory and it is not easy to find the right partners there."
At any rate, Urs Pfister recommends tackling this topic sufficiently early. Because the factor time is sometimes almost the biggest challenge: "With multi-family dwellings, it can take ten or more years until the last inhabitant has an electric car. At companies, however, topics such as CO2 emissions play a substantially more important and more costly role, which is why many will change over in part or in full to electric drive in the next round of procurement. Already because fully electric models in the current chip crisis are available more quickly from many car manufacturers than combustion-engine vehicles that are no longer prioritised." In Urs Pfister's opinion, at the latest on the day on which the battery-powered fleet vehicles are delivered, the right charging infrastructure should be available. A parking space without a charging possibility is then otherwise as useful as an office without access to the Internet.
