After three years, the Automotive Testing Expo will return to India in April 2023. The show will avail the platform to host the most up-to-date technologies in ADAS and autonomous vehicle testing, NVH measurement tools, test rigs, simulation packages, durability testing technologies, crash testing, dynamometers, emission measurement systems and dynamic assessment tools, as well as countless service providers such as proving grounds and test facilities. The German edition, which will take place between 13 and 15 June 2023 in Stuttgart, will be hosted on a bigger scale with expected exhibitors of more than 450.

In light of the evolving dynamics of the automotive testing industry, organisers of the upcoming Automotive Testing Expos in Germany and India are placing big bets on the events.

The Indian edition of the Automotive Testing Expo will take place between 18 and 20 April 2023 in Chennai, while the German edition will happen between 13 and 15 June 2023 in Stuttgart. Apart from these two editions, the show will be hosted in Korea, China and US.

Tony Robinson, Founder and CEO of UKIP Media & Events, said, “After three years, we are once again hosting the Automotive Testing Expo in India. It is a long gap. We received a terrific response when we announced a few weeks ago that we would return to Chennai in April 2023. Many very excited companies want to exhibit their new and existing technologies. We will find people in India who haven’t had a chance to see the new things available in the automotive testing industry. They will be very keen to come out and look at everything that’s on show in April next year. So we are excited.”

Automotive Research Association of India (ARAI), Automotive Test Systems, DEWESoft India Pvt Ltd, Keysight Technologies India Pvt Limited, MTS Systems Corp and National Instruments are others who have confirmed their participation. In 2020, the Indian edition of the Automotive Testing Expo hosted 125 exhibitors and the same number is expected for the upcoming edition.

The Germany show did not take place in 2020 and 2021 thanks to the Covid pandemic. However, the show came back in 2022, which Robinson terms as a ‘fantastic show’. “Visitors came to the show for three days to see the latest technology in action and to learn about their uses and advantages. I would expect it’ll be even more fantastic in 2023. We expect to see more people come in because this year there has been a transition between the pandemic and people coming out and feeling comfortable,” added Robinson.

The Stuttgart Automotive Testing Expo, which takes place concurrently with a show on ADAS and autonomous vehicle technology, is expected to include between 450 and 500 exhibitors. “As a result, all major players are back in operation and prepared to display. There will also be numerous new businesses and start-ups along with the established major automakers,” said Robinson. The last edition in Stuttgart witnessed over 300 exhibitors.

Leading companies such as Anthony Best Dynamics; Applus+ Laboratories; DEKRA; DEWESoft GmbH; Diversified Technical Systems, Inc.; dSPACE GmbH; Keysight Technologies; Link Engineering Company; MTS Systems Corporation; National Instruments Germany GmbH; Robert Bosch; Rohde & Schwarz GmbH & Co KG; Siemens AG; ZF Friedrichshafen AG; SGS; TUV SUD Product Service GmbH; Michigan Scientific; Photron and others will exhibit at the Stuttgart show.

Despite the challenges brought on by the Covid pandemic, the organisers are closely monitoring the shifting trends in the automobile and automotive testing industries, which aids in their show planning. “Our job is to make sure we keep an eye on the developments and track down the new businesses that are entering the market. And we always act in that way. We take care to stay in touch with the important figures in the field of automotive testing engineering. We are dealing with a highly specialised community, so it’s essential that we are tracking and communicating and discussing with the automotive testing teams that cover many different facets of engineering. Our responsibility is to establish connections with all of the new businesses that are entering the sector. When marketing an event, we are in touch with the right people. It’s not frightening; it’s just what we do,” explained Robinson.

The shifting focus of the global auto industry from ICE vehicles to electric, autonomous and shared vehicles presents a wide range of opportunities and challenges, and this transition reflects on automotive testing as well. “The automotive testing market is exciting and in transition. We have been in the automotive testing world for nearly three decades, and any industry will have a transition. There’s no evidence that the big players are dropping by the wayside. Companies that are very ICE testing-oriented are not likely to come out exhibiting. This is not a great period for them. But then again, the rise of the battery car and battery testing (and range testing) and a lot of other things that we’ve been talking about, like AI and simulation, are things that are bringing new companies in,” added Robinson.

Robinson asserts that the complexity of automobile testing technologies and systems is drastically increasing, pushing the industry for automotive testing very hard. The newest products, services and technology are displayed at the automotive testing expos to help test, development and validation projects move more quickly. Robinson further explained, “The word I tend to use is fidelity. Automotive testing is a relatively young industry; if you go back even to the 1960s and 1970s, a lot of automotive testing was done in real life – physical testing of cars, natural crash testing of cars with human drivers. As the computer and IT industry developed and blossomed, a fascinating automotive test and development engineering industry grew. Higher and higher levels of fidelity are required in automotive testing for infinite and finite environments. We’re in an environment where everything is pushing automotive. Obviously, the electric and hybrid vehicles and batteries themselves need a lot of testing. The range needs a lot of testing. Autonomous vehicles push the boundaries to a completely new level. The growing penetration of software, sensors and AI is giving rise to a whole new range of companies that can enter the industry.”

“In a number of our shows, we have low-cost, smaller booths to enable starts-up and innovation companies, new companies to come to the event without having to spend a lot of money,” added Robinson.

Researchers at Chalmers University of Technology, in collaboration with industry partners, have published a study in Nature Communications demonstrating that reconfigurable battery pack architectures can extend electric vehicle battery operational life by more than 20 percent under specific conditions.

In conventional electric vehicle battery packs, cells are wired in a fixed series configuration, meaning the weakest cell dictates the overall capacity, performance and lifespan of the entire pack. The architecture evaluated by the Chalmers engineering team uses integrated electronic switches and a centralised battery management system to monitor individual cells or cell groups. When a cell experiences accelerated degradation or reduced capacity, the system bypasses the degraded unit while electric current continues to flow through the remaining functional cells.

Albert Skegro, a PhD student at the Department of Electrical Engineering at Chalmers University of Technology, said, "They must all move at the pace of the slowest person and stop when that person stops, regardless of how much energy the others have left. With the architecture we have modelled, the battery can instead bypass the cell that is causing problems and continue using the remaining cells."

Changfu Zou, Professor at the Department of Electrical Engineering at Chalmers, said, "Reconfiguration is not an on-or-off choice. It is a spectrum. Where a manufacturer chooses to position itself on that spectrum determines how much of the potential benefit can be realised."

In a representative modelling scenario featuring an 80 kWh battery pack driven 12,000 kilometres annually over an 18.8-year vehicle lifespan, the reconfigurable system deferred battery replacement by approximately 14 months. The researchers noted that the technology yields the highest performance gains in high-voltage vehicles, including 400-volt and 800-volt electric passenger cars and commercial trucks, where higher cell counts in series increase the statistical probability of individual cell variance.

A techno-economic analysis included in the study determined that implementing cell-level switching hardware increases initial pack production costs by approximately nine per cent based on prototype-scale volumes of 1,000 units. The researchers identified an economic break-even threshold at a 12 percent cost increase, noting that volume manufacturing would lower component costs and increase financial viability for fleet operators and private owners. While prototype applications such as Volvo Cars' SmartCell concept and experimental road vehicles exist, mass-production vehicles using reconfigurable battery packs are yet to enter the commercial market.

Honda R&D, a subsidiary of Honda Motor Co., has developed underlying technology for a magnetic coupling wireless power transfer road system in partnership with Taisei Corporation and Taisei Rotec Corporation.

The system enables wireless in-motion charging for electric vehicles, including passenger cars and heavy commercial fleets. The partners plan to initiate demonstration testing on public roads starting in FY2027.

The technology integrates high-power-density receiver and transmitter units from Honda with a high-response direct current power supply system from Taisei and road-embedding construction techniques from Taisei Rotec. By supplying power to electric vehicles while in motion, dynamic wireless power transfer reduces the need for stationary charging infrastructure. The initial commercial focus targets logistics and transport operations, where continuous operation offers economic benefits.

The ground assembly embedded in the roadway combines the inverter and coil into a single unit designed to connect via direct current distribution. This design reduces component counts, simplifies wiring and supports installation into existing road surfaces through standard milling methods. The road pavement structures are engineered to withstand continuous traffic loads from vehicles weighing up to 20 tonnes (20,000kg).

Testing conducted at Taisei Group’s T-FIELD facility in Satte verified system stability and structural durability. Starting in late 2026, the companies will build a test roadway at T-FIELD Tamura to evaluate long-term durability under one million wheel-load cycles, measure power transfer efficiency at outputs up to 150 kW and analyse electromagnetic shielding.

The partnership will also join the Tateyama Expressway demonstration project managed by East Nippon Expressway Company starting in 2027.
