Minister President Winfried Kretschmann visits ADS-TEC Energy in Nürtingen

Innovative technologies for the mobility transition aroused great interest

As part of a summer tour through Baden-Württemberg, Minister President Winfried Kretschmann visited four companies focusing on IT and energy. On Thursday, 2 September, he made a stop at ADS-TEC in Nuertingen. The Prime Minister was particularly interested in ADS-TEC Energy's innovative fast charging technologies.

After a short welcome round, the battery-based fast charging system ChargeBox was presented in the outdoor area and a charging process was demonstrated live on an official car of Minister President Kretschmann, an Audi e-tron. ADS-TEC Energy's energy management technology platforms enable ultra-fast charging in minutes using the existing power-limited grid. The Minister President was particularly enthusiastic about the charging technology of the compact ChargeBox, which can be used to expand the fast-charging infrastructure to the last mile in inner cities or residential areas. In many places, this saves a complex and expensive network expansion, which cannot be realised everywhere for reasons of space alone.

“To bring about the mobility revolution, we’re dependent on the further expansion of charging infrastructure and innovative fast charging systems. Storage specialists like ADS-TEC Energy are innovation drivers in the field of electromobility”, states Minister President Winfried Kretschmann.

With more and more e-vehicles, it’s clear that fast charging is needed in as many places as possible – not just at motorways or charging parks. In conversation with host and CEO Thomas Speidel, the realisation was confirmed: the more everyday comfort and fewer restrictions for citizens, the faster the mobility change will find acceptance.

“It’s really important that fast charging is possible everywhere, because electric mobility shouldn’t call for route planning or make people anxious about range,” declares Thomas Speidel.

As a representative of the Federal Association for Energy Storage (BVES), he addressed the request for timely regulatory solutions to the Minister President. “We have major obstacles in Germany and need to throw off considerable ballast if we’re to achieve the goals we’ve set”, explains the ADS-TEC boss with regard to regulatory and bureaucratic framework conditions as the main problem of nationwide implementation.

With its focus on IT and energy, the family-owned company works on the current issues of the day and plays a leading international role, especially with its newly developed battery-based fast-charging technology for electric vehicles. The ADS-TEC Energy division is aiming to go public on the NASDAQ technology exchange in New York in 2021 as part of a SPAC transaction, as the company recently announced.

The delegation was also able to find out about the mobile and off-grid version in the form of a truck trailer on site. The company had already presented the ChargeTrailer together with Porsche at the strategy dialogue in Stuttgart in September 2020.

Minister President Winfried Kretschmann: “In Baden-Württemberg, advanced solutions for climate- friendly and connected mobility are being developed and implemented. With the help of the Automotive Industry Strategy Dialogue BW, we’re continuing to work consistently on shaping change and thus on preserving jobs and prosperity in our state."

ADS-TEC sees itself as a provider of system platforms on which customers can set up and adapt their applications and services. ADS-TEC Energy's battery storage and fast charging systems in particular open up a wide range of opportunities and business models that are already being used today by a broad customer base from the energy sector, industry and OEMs such as car manufacturers.

ADS-TEC Energy's high level of innovation is made particularly clear by the award of the GreenTech Award in spring 2021. The award relates to the internationally registered patents in the field of climate protection technologies. In addition, the ChargeBox with its charging columns was the first battery- based fast charging system to receive the new TÜV SÜD seal for the EU, Great Britain, USA and Canada. Series production was started in the summer of 2020 and in the meantime the first 1,000 or so fast charging points have already been successfully delivered.
