Grid Connection of Charging Infrastructure – Quick and Easy

The country needs charging stations. However, these must be connected with telecontrol technology – and in a grid-compliant way. The LEONHARD WEISS company offers this service and more all across Germany. At this company from Göppingen, Baden-Württemberg, the Station Design department relies on flexible hardware and software from WAGO – because the connections function quickly and easily in around two-thirds of all grid territories, and also because this choice lets them retain expertise and added value within the company and remain well-positioned for the future.

The development and expansion of charging infrastructure for e-mobility have become crucial for station design. “A large portion of our work currently focuses on e-mobility. This includes everything, not just charging stations – from the mains transfer point, to after-sales and maintenance services,” says Christian Kong-Lochbihler, Senior Site Engineer in the Station Design department at LEONHARD WEISS. With 20 employees, his department successfully constructs AC and DC high-power charging stations throughout Germany with a charging capacity up to 350 kW.

Connecting Charging Infrastructure – Here’s How WAGO Supports You:

A plug-and-play solution for quick and easy telecontrol connection of customer transfer stations
Grid-compliant connection in accordance with distribution network operators’ requirements (TCRs) in approximately three quarters of German medium-voltage grid territories
Modular, flexible solution components consisting of software and hardware – tailored to the needs of system integrators, switchgear manufacturers and station manufacturers alike.

Plug-and-Play Telecontrol Connection

As an experienced service provider, LEONHARD WEISS provides the entire value chain of e-charging technology, from the transformer station, to the roofs over charging stations, all from a single source. Their services range from initial consultation, site analysis, execution and commissioning, to operational management, service and maintenance. “We work for the three largest charging network operators in Germany,” says Kong-Lochbihler. “We implement telecontrol station connections according to the technical connection rules (TCRs) of many different grid operators. Using a telecontrol system and the WAGO Customer Substation application, we can fully handle around 80 percent of the different TCRs with a plug-and-play approach.

A Flexible System for Openness and Added Value

As an energy technology provider, WAGO came at the right time with its plug-and-play solution for the telecontrol connection of customer transfer stations. “Of course we took a look at what was on the market – we even checked out other telecontrol system producers that we had already used,” reports Christian Kong-Lochbihler. The problem was that these were often closed, proprietary systems. “But we didn’t want to tie ourselves completely to one option – we wanted to have in-house value creation and carry out the cable wiring and built-in tests ourselves, for example. This was astonishingly easy to do with WAGO,” he says. In Kong-Lochbihler’s eyes, the handling is another advantage: “The software is easy to understand and for my employees to operate.”
