Twaice/Vispiron: Munich Battery Lab examines the cells closely
The battery analytics software company TWAICE and the R&D service provider VISPIRON SYSTEMS have opened their joint MUNICH BATTERY LAB, a battery lab for analyzing the behavior and optimizing the operating batteries in vehicles of all kinds. According to the providers, this is unique in Munich and aims to set a milestone for greener and future-oriented mobility. It was opened in the presence of Munich's second deputy mayor, Katrin Habenschaden (Greens), as well as the Green Party chairpersons in the state parliament, Katharina Schulze and Ludwig Hartmann. A representative of the Green Party's Bundestag member from Munich, Jamila Schäfer, was also on site.
"I am very proud of this location here. Anyone who wants to pursue sustainable and successful economic policy today must invest every spare euro in the creation of innovation spaces, and we can celebrate the Munich Battery Lab here as a best practice example," explained Habenschaden.
While others were debating e-fuels, the future of mobility was being fine-tuned here, Habenschaden further praised. She pointed out that only just over four percent of cars in Munich are purely electric, with slightly better rates in the trade sector. But that is still too little for the 2030 goal of 15 million BEVs in Germany. She noted a gap between the willingness of one-third of people to purchase an e-car and actual action, which needs to be closed. "Against supposed technological openness, we must set real technical progress," she demanded. This also lays the foundation for global competitiveness and "Future made in Germany," in an area where we have currently lost ground. This is not a "nice to have," but a "must have."
The focus is on testing lithium-ion batteries for performance and stability under predefined environmental influences. The two Munich companies have set up a testing infrastructure based on the current state of technology for battery testing within six months. The laboratory allows the analysis of various cell types in the battery on more than 100 square meters of floor space, with a current strength ranging from one to several hundred amperes, cooling capacity of 40 kW, and using ten temperature chambers. With over 100 available measurement channels and temperatures ranging from -20°C to +80°C, it creates one of the most significant and technologically advanced battery competence centers in Germany.
"Looking at developments from the past, you see that technologies are never fully explored. It is about continuously improving and optimizing techniques. And that's exactly what is being done with the Munich Battery Lab – batteries are being analyzed more precisely, made better, and more efficient. This is exactly the development we need,” added the Green Party faction leader in the Bavarian State Parliament, Ludwig Hartmann.
He praised the providers as "pioneers of the energy transition" and referred to the history of the Renewable Energy Sources Act, which had long been ridiculed but, after many delays, brought the breakthrough for wind and solar energy. And because these are not "baseload capable," storage technologies are needed to supplement them. The batteries generally need to achieve longer life cycles; only then can the transition to alternative drives be truly sustainable. Hartmann also called for "technology clarity instead of technology openness" and appealed to Berlin politics to end the "smoke screen debates" about e-fuels. This slows down the clean drives, which, in combination with sector coupling, could result in a perfect interplay between mobility and the energy transition.
Batteries of all kinds: Test series under special conditions
The lab enables the analysis of multiple battery types and chemistries, parameter and lifetime tests, temperature cycling tests, as well as calendar or cyclic aging tests (electrical, thermal, or combined). Customers benefit from a better understanding of battery behavior, thus optimizing their battery development. The testing infrastructure will provide additional data for TWAICE's battery analytics.
"With the new Munich Battery Lab, we will advance the groundbreaking technologies of our customers and accelerate the expansion of e-mobility. The new fuel consists of data, algorithms, and capacities,” explained Amir Roughani, CEO of VISPIRON GROUP.
The facility will make an important contribution to deeply analyzing battery aging and behavior. As part of the Battery Research Center, this allows us to further improve our software and, along with our partner, make a significant contribution to climate-friendly mobility and energy, said Michael Baumann, Managing Director of TWAICE. The aim is to fully unleash the potential of battery technology. These are the key element but also the Achilles' heel of e-mobility. We want to advance pioneering technologies among car manufacturers and thus promote the expansion of electric mobility in Germany, added TWAICE Co-Founder and CEO Stephan Rohr, noting that “the lab also helps battery storage efficiently balance the volatility of power grids and supports the expansion of renewable energy sources.”
From science to practice: Diverse applications
TWAICE, founded in 2018 following a research project at TU Munich on the second life and lifespan of Li-ion batteries and the development of server-based logic for battery condition diagnosis, sees itself as a world-leading provider of battery analytics software and has years of experience in analyzing field and lab data. For the past two years, models for automotive manufacturers, energy sector customers, and others have been efficiently and quickly parameterized in the existing battery lab. These models are used in the development of battery-powered products. They are also part of our own platform, enabling customers across various industries to make complex battery systems more efficient, sustainable, and reliable during operation.
The applications are diverse: For instance, with TÜV Rheinland, there’s a solution to determine and predict the condition of electric and hybrid vehicles, which could become highly relevant for the used car market. The management and IT consultancy MHP - a Porsche company - uses the portfolio to share knowledge with customers along the battery value chain. Munich Re offers the first performance guarantee insurance for Li-ion batteries based on TWAICE's battery monitoring and analytics. The fleet management and telematics provider ViriCiti, now part of ChargePoint, has partnered with TWAICE to integrate battery expertise into fleet management. The fleet management software provider Sycada also collaborates with TWAICE to provide its customers with battery insights.
VISPIRON SYSTEMS is a development partner for renowned manufacturers and suppliers in the industry. Projects in the areas of Future Mobility, Future Energy, and Digital Transformation are supported from idea generation through concept development to implementation, including training. The company continuously invests in appropriate testing infrastructure for tomorrow's technologies. The so-called E-labs have been helping to provide more test capacities for the growing electromobility market since 2019.
