Electric construction machinery is already a reality. Although they are far inferior to combustion engine solutions in terms of numbers, there are powerful all-electric forklifts, excavators and more.
For these zero-emission electric machines to be competitive, they must operate to the same standards as conventional combustion engine variants. Machine downtime costs money, and unexpected breakdowns can have a direct impact on meeting the schedule. A key challenge here is the necessary battery charging. Thomas Adermann and Christian Pelger from DEUTZ AG provide an overview of what the construction site of the future could look like and how the charging problem can be overcome.
Although overnight charging is an option, it is often not sufficient for power-intensive machines such as heavy excavators. To avoid long delays in work, fast charging is the key. However, it is not always easy to set up fast charging stations on construction sites. If they are available at all, the grid connections may not be able to supply the required amount of energy. The solution is to get the power you need to where you need it, when you need it.
