Porsche driving event at TEAG in Erfurt

Category: EU Reference projects ChargeBox

How does fast charging work on the road - that was the topic of a three-day electric driving event with four Porsche Taycans and around 80 participants on the campus of TEAG (TEAG Thüringer Energie AG) in Erfurt from 27 July 2020. The High Power Charging Event was organised by the Porsche Centre Erfurt with the support of TEAG as a customer event with test charging at the newly installed ultra-fast charging station ChargeBox from ADS-TEC Energy. The aim of the event was to make the topic tangible for potential customers and interested parties and to convey how uncomplicated and simple ultra-fast charging can be. It became clear how close a charging process comes to the conventional refuelling process in terms of time and what advantages this new technology has to offer beyond that.

Most powerful e-sports car needs most powerful charging technology

First of all, the customers and interested parties were welcomed at the fast-charging points and introduced to the world of the Volkswagen by Porsche. The physical well-being was also catered for on these hot July days. The manufacturer ADS-TEC Energy from Nürtingen was on site with service employee Frederik Elschenbroich to answer technical questions about the new charging technology. He answered the questions of the diverse clientele all three days competently and with a great deal of advice, and in retrospect states: "An astonishing number of customers could not imagine that it actually works so easily and quickly and showed great interest in the technology behind it. 

Unique worldwide

The basic question is: How can High Power Charging work at an ordinary grid connection point, even though it is limited in its power? The solution lies in the powerful ChargeBox battery system, which was installed at the TEAG site a few metres away from the charging points (up to 100 metres are possible). It permanently charges itself from the grid at low power and releases this collected energy back to the vehicles at full power when needed. Even with successive charging processes, the power output is guaranteed. The system can deliver up to 320 kilowatts per charging point, which is more than even a Taycan can currently accommodate. This level of performance combined with a capacity of 140 kilowatt hours, including fast-charging inverter technology, air-conditioning and control, built into a mini-cube with a footprint of just 1.2 x 1.2 m, is unique in the world. For many urban charging locations, this compact system opens up completely new possibilities, especially when, for reasons of space and cost, an upgrade in the form of a complex medium-voltage system is out of the question.

Enthusiastic customers

During the driving event, there were 72 slots in which the Taycans could be extensively tested. Charging at the High Power Charger was obligatory after the test drive. On the displays of the charging stations, it was possible to follow how the vehicles used their full charging power - in the case of a Taycan, 270 kilowatts - and were recharged in just a few minutes. The customers were consistently enthusiastic and spontaneously convinced by their positive experience.

Denis Schuldig, Head of Product and Project Management at TEAG in the Mobility Division, was also pleased with the extremely successful event: 

 "As expected, the enthusiasm after driving was great. The fact that High Power Charging really only takes minutes left a special overall impression."
