Ineos postpones electric off-road vehicle indefinitely

The carmaker told British Autocar that there are two reasons for the postponement of the Fusilier market launch: the hesitant acceptance of EVs among consumers and uncertainty in the industry regarding customs duties, timetables and taxes. Ineos Automotive presented the electrically powered off-road vehicle at the end of February. It was to launch two drive options – a fully electric one and with a petrol range-extender. Ineos Automotive did not yet provide performance data for the two drive options at the February launch. Details of the drive system and the timetable for the market launch were originally to be confirmed in autumn 2024. Now, things are different. “Charging infrastructure for EVs in most markets continues to grow and consumer confidence will match that, but for the industry to meet net-zero targets there needs to be long-term clarity from policy makers and a number of technology options available considering factors like raw materials, infrastructure and affordability,” the carmaker told Autocar. And then there is legislation, according to which the Ineos may not be able to sell its range-extended version in Europe or the UK after 2035. The Ineos Fusilier was to be developed in collaboration with automotive supplier Magna and later manufactured by the Austrians. The first two models, the Grenadier positioned above the Fusilier and the Quartermaster pickup, were already developed in collaboration with Magna – although these were still combustion engines. autocar.co.uk, bloomberg.com

CATL unveils electric CV batteries under new ‘Tianxing’ brand

CATL says the Tianxing batteries have energy storage capacities ranging from 30 to 200 kWh, making them suitable for a wide range of commercial vehicles across various industries. The company uses non-heat diffusion technology, double-layer large-surface liquid cooling, and aviation-grade insulation materials for maximum safety. Additionally, the batteries incorporate low-lithium consumption graphite in the anode material and utilise bionic self-healing SEI passivation film technology for a long life. CATL skips the module level in the Tianxing batteries and uses the advanced cell-to-pack (CTP) method, which allows for higher energy density, reduces weight, and saves costs. The company initially offers two such products in the domestic market – Tianxing L Superfast Charging Edition and Tianxing L Long Range Edition. Both electric CV batteries are for light commercial vehicles (LCVs) and include an 8-year/800,000 km warranty. The Tianxing L Superfast Charging Edition battery is a 140 kWh unit with an energy density of 155 Wh/kg. It supports 4C charging, which theoretically means it takes only 15 minutes for a full charge. CATL added that this battery can replenish 60% of charging in just 12 minutes. The Tianxing L Long Range Edition battery is a 200 kWh unit but with a lower energy density of 200 Wh/kg. CATL says it is suitable for medium and long-distance transportation service providers and companies with high-frequency use scenarios that make charging stops inconvenient. They deliver a range of 500 km, allowing customers to transport goods from Hohhot to Beijing non-stop. CATL says that it is already mass-producing Tianxing L batteries and that these units are present in 21 models in the following 13 companies: Dongfeng Commercial Vehicles Dongfeng Light Vehicle SAIC Maxus SAIC Hongyan Foton Motor JAC Group Jiangling Motors Qingling Motors LiuGong Machinery Yutong Group Shaanxi Tongli DST Lingshi Auto weibo.com (product announcement in Chinese), weibo.com (list of companies in Chinese), 36kr.com (in Chinese), autonews.gasgoo.com

Hyundai to halve slow charging time in future EVs

Hyundai says in its latest sustainability report that it is considering a 50% reduction in slow-charging time compared to current levels with the introduction of its next-generation dedicated EV platforms. The company is developing an ‘eM’ platform for passenger EVs and an ‘eS’ platform for Purpose-Built Vehicles (PBVs). In addition to faster slow-charging time, it aims to increase battery capacity by 40% and motor output by 28%. Hyundai uses its latest battery pack in the Ioniq 5 N, which has a 10.5 kW three-phase on-board charger. This battery pack is an 84 kWh lithium-ion unit featuring the company’s fourth-generation technology and fully charging it takes seven hours and 35 minutes. If Hyundai substantially reduces AC charging time, say, in the Ioniq 5 N’s case, to under four hours, customers may not need to keep their EVs charging overnight. For example, one could start charging their EV through an AC charger at their office when they arrive in the morning and have it fully charged well before the lunch break. Additionally, as customers would need to rely less frequently on DC chargers, they would significantly lower their charging cost and also extend the life of the battery pack, saving even more in the long run. On a mass level, reduced use of DC chargers can also lower the load on the power grid. Most automakers are focusing on increasing the DC charging input of their EVs, with Chinese companies like Zeekr and Li Auto having crossed figures well over 500 kW. However, improving AC charging may do the greater good for the charging ecosystem globally. Media reports suggest Hyundai will first use the eM platform in the Genesis GV90, a full-size three-row SUV. The upcoming flagship EV may debut Hyundai’s slow charging improvements as well. The South Korean automaker has confirmed that eM platform-based EVs will include novelty features like swivelling seats in the first and second rows, a pop-up display, and Level 3+ advanced driver assistance functions. Hyundai plans to offer eM platform-based EVs with cell-to-module battery packs featuring better energy density than the cell-to-module units of the models based on the Electronic Modular Platform (E-GMP). Moreover, the company will use LFP cells instead of NCM cells in certain lower-end cars to price them competitively. The eM platform will cover B to E model segments and offer a broader range compared to E-GMP. At its 2023 CEO Investor Day event, Hyundai said that it will launch four mainstream EVs and five Genesis EVs based on the new modular chassis between 2025 and 2030. The company also revealed that Kia will use the same platform for four EVs during that period. bloter.net (in Korean), hyundai.com (in Korean | page no. 25)

Porsche considers acquiring a stake in Varta battery subsidiary V4Drive

According to consistent media reports, Varta has officially announced that it is examining a possible majority investment in its subsidiary V4Drive, which was founded in 2022, with Porsche. Both parties have signed a non-binding letter of intent. According to Varta, V4Drive will initially be outsourced before Porsche buys in via a capital increase. However, the deal has not yet been finalised. The transaction is said to depend on various factors and Porsche first wants to take a close look at the balance sheets. Varta presented the first V4Drive cell suitable for electric cars in the 21700 format (2.1 cm diameter, 7 cm height) in 2021. In April of that year, the company initially presented it as the basis for a battery that would serve as a “booster” in premium and sports vehicles or as a storage unit for recuperation energy in hybrid vehicles. Just a few months later, Varta then announced “larger lithium-ion round cells” that would go beyond the 21700 format and would also be suitable as a stand-alone traction battery. Varta’s CEO at the time, Herbert Schein, was convinced “that our round cell formats represent excellent alternatives for the construction of battery electric vehicles in the performance sector due to their unique properties.” Varta wanted to push ahead with commercialisation quickly: Pilot production of V4Drive cells in the 21700 format was announced at the time for the end of 2021, with mass production scheduled to begin two years later at the end of 2023 – and production capacity of at least 2 GWh. According to a statement from Schein at the time, customer demand would determine the extent to which the company would subsequently enter into the production of V4Drive cells. Interestingly, an order from Porsche from June 2021 had already been placed at the time. The Zuffenhausen-based company has therefore been interested for a long time. However, Varta put its plans in the automotive sector on hold at the end of 2022. The new factory construction for the V4Drive battery was only to be continued after binding customer commitments, it was said at the time. There was therefore apparently a lack of interested parties for the performance cells. However, the operation of the pilot plant continued as planned. In August 2023, rumours again flared up that Varta was continuing to work on the series production of battery cells for electric cars. This was indicated by a purchase agreement for anode copper foil with a Korean supplier. Meanwhile, Porsche has long indicated that it wants to produce its own battery cells. Around three years ago, Porsche founded a battery subsidiary called Cellforce – initially with Customcells as a partner, but Porsche has since taken over completely. Cellforce is currently building a pilot plant near Reutlingen with a production capacity of up to 1.3 gigawatt-hours. In addition to the factory currently under construction near Reutlingen, the company is looking into a potential expansion to over 20 gigawatt-hours at a second site in 2023. A few weeks ago, however, Tagesspiegel Background reported that Porsche could not currently bring itself to build a large battery cell factory. Porsche had confirmed plans for such a battery factory as recently as mid-2023, when North America was initially considered the favourite. However, Porsche was later rumoured to be interested in an area in Brandenburg, specifically a site on the grounds of the Schwarzheide/Schipkau airfield in the district of Oberspreewald-Lausitz. According to Automobilwoche, investments of two to three billion euros would be required for 20 gigawatt-hours. Porsche apparently does not want to manage this alone but is looking for partners. The sports car manufacturer also wants to work together with Volkswagen’s battery sister company PowerCo. automobilwoche.de, wiwo.de (both in German)

Tesla gets preliminary approval for expansion of Grünheide plant

Tesla wants to increase production capacity in Grünheide from 500,000 to one million vehicles per year by expanding its factory. These plans have been known for some time. According to the German news agency DPA, the Brandenburg State Office for the Environment has now given the green light for certain expansion work on the existing site, meaning Tesla can begin initial construction work ahead of schedule. The basic plans include the construction of another large hall and the optimisation of existing facilities. According to DPA, battery storage production will also be increased. Tesla’s first measures now include creating a logistics area for new cars (including underground pipes), constructing stairwells at the press shop, and installing solar panels on roofs. Tesla submitted the approved application for the expansion of its plant in Grünheide to the state of Brandenburg in March 2023. It was the first application for partial approval; others will follow. According to earlier reports, the expansion involves 70 hectares in the north of the site. While the current development plan still covered the clearing, Tesla had to reapply for the expansion of the factory itself. The planned hall must thus be eligible for approval under the Federal Emission Control Act. Tesla is carrying out the approved preliminary work at its own risk, as final approval is still pending. As mentioned, the production facilities will be built on the existing factory premises. According to earlier statements, Tesla has optimised planning and production processes so that the previously assumed and contractually agreed quantities of fresh water are also sufficient for the expansion. The company will achieve this by fully treating and reusing wastewater from production. In other words, the Texan company estimates that it can double its production capacity while using the same amount of water. The expansion plans are flourishing at a time when Tesla is still in the ramp-up phase of the first factory section. According to DPA, the latest status is that around 300,000 units have rolled off the production line in Grünheide in twelve months. The workforce currently comprises around 12,000 employees. Incidentally, the expansion plans should not be confused with an expansion announced in September 2022 for a new logistics centre, including a freight station. It will be built outside the existing site on a good 100 hectares of land in the east. The project is met with strong protests in Grünheide. dw.com, msn.com

Testing the Kia EV9 – the South Korean luxury SUV

In the 1980s, the German automobile industry decried that Japan was moving to export its cars to Europe. A decade later, South Korean companies like Hyundai and Kia were seen as the new threat. With their emphatically simple and affordable cars, the new manufacturers catered to customer groups that the German carmakers could no longer reach. However, the reputation of South Korean cars was not good at first: to put it kindly, they were not considered to be of particularly high quality and only partially reliable, but they were cheap. Almost 30 years later, the development could hardly be more dramatic. In front of us is a test car for well over 82,000 euros – with the Kia logo on the bonnet. As a rear-wheel drive model, the EV9 is “already” available from 72,490 euros, but for the test, Kia sent the all-wheel drive model in GT Line equipment. The brand has developed enormously since its European launch and, thanks to its affiliation with the Hyundai Group and access to its platforms, has brought ever-better cars onto the market. Kia has used the shift towards electric mobility to expand its own range upwards. The result, which is being tested here, is the EV9 – a 5.01 metre-long electric SUV that is actually aimed at the Asian and American markets. However, as Kia sees the potential to sell a few vehicles in Europe as well, the EV9 is also offered in Germany. And with data that is quite impressive. The battery holds 99.8 kWh, can be charged to 80 per cent in less than 25 minutes thanks to the 800-volt system and the electric all-wheel drive with two motors, it delivers 283 kW. Not just the data that impresses However, our experience after over 1,000 kilometres in the EV9 also shows that it is not just the figures on paper that are convincing, but also the things that cannot be easily squeezed into a table of technical data – driving behaviour and software, to name just two examples. However, nothing is perfect and there is room for improvement in the EV9. Take fuel consumption, for example. A car as large and angular as the EV9 is, of course, no miracle when it comes to consumption, but even at temperatures in the double-digit range, the EV9 could only be brought below 20 kWh/100 km on routes that were driven very efficiently. With the driving style in our test, the average was 25.4 kWh/100km, which gives a calculated range of 391 kilometres. The onboard computer of the test car was last reset 3,334 kilometres ago and shows an average of 27.5 kWh/100km for this route, although we cannot make any statement about the driving style of other users. With this consumption, 361 kilometres would still be possible with a full battery charge – and if you calculate the usual long-distance range of ten to 80 per cent charge level, this results in only 262 kilometres between two charging stops. Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal Image: Sebastian Schaal For large parts of our test, we were travelling in very good conditions. On a section of the motorway, we were able to see that consumption can be noticeably higher in poorer conditions. It had cooled down to just four degrees overnight, the embankment was lightly covered in snow, the road was damp – and the interior temperature was set at 21 degrees. And the fuel consumption in the 120-130 kph speed range rose towards the 30 mark. That brings the calculated real-world range closer to 300 kilometres and the 70 per cent value in the order of 215 to 230 kilometres. For a car with a 99.4 kWh battery. Considering the aerodynamics with the high, massive front and the steeply sloping rear, which leaves a large hole in the air, this is almost an expected result. Every extra kilometre per hour on the motorway has a noticeable effect on fuel consumption. On the test average with country roads and some city traffic, however, the range is fine again. In addition to range, a good long-distance electric car also needs good charging behaviour. And this is where the EV9 can play to its strengths. However, the charging curve differs significantly from other models on the E-GMP platform, which the EV9 also uses. The 77.4 kWh battery, familiar from the EV6 or Hyundai Ioniq 5, charges at up to 240 kW at its peak, but reduces somewhat at higher charge levels. Not so in the EV9: here we didn’t see more than 205 kW on the display. On the other hand, an output of around 200 kW is constantly available up to just over 60 per cent charge level. And even then, the power is initially only reduced to 175 kW before dropping to 104 kW at 80 per cent. A constant 200 kW over this wide range is nevertheless remarkable. Such a constant charging curve is almost reminiscent of the BMW i3 – only by a factor of 4 higher. While there is little to criticise about the fast charging itself, the charging planning is still not quite ideal: the Kia always planned the charging stops on the way to the destination up to 100 per cent, which is unrealistically long, however, this can be altered in the vehicle’s settings. The sat nav’s initial prediction of when you will arrive at your destination is therefore not useful. A detail criticism that you might be able to get over in another price category. However, the fact that an 80,000-euro car does not have a function that numerous free smartphone apps offer could be improved. The selection of charging stations that the sat nav should take into account, on the other hand, can be filtered well – for example by provider or charging capacity. If a fast charging stop is automatically scheduled, the car automatically…

Kontron books major wallbox order from German OEM

According to Kontron, the contract covers the development and delivery of fully networked wallboxes. Series production with an order volume of 120 million euros is set to begin in the third quarter of 2024 and the contract will run until 2028, according to the statement. The wall box chargers will be developed and manufactured on behalf of the customer for the European and Chinese markets and will also differ in their design for these two markets. The customer is a German manufacturer of premium vehicles with whom eSystems already has a long-standing partnership, according to the statement. The new wall box charging stations, which Kontron refers to as a new generation , is based on the ghostONE platform created by eSystems. This is a customisable white label solution. It is fully networked via Ethernet, LTE, WiFi, EEBUS, MODBUS/TCP, OCPP and ISO15118. “Our fully networked wallbox can do ‘smart charging next level’,” says eSystems Managing Director Jochen Paukert. “Charging an electric car is then not just a matter of refuelling with electricity. Our wallbox enables the safe integration of renewable energy into the grid, the use of self-generated PV power and lower costs thanks to dynamic tariffs.” The wallboxes also fulfil the highest security requirements for data and are supplied with updates remotely. The fact that Kontron, a specialist in computer technologies, has been awarded the contract is due to the fact that the Augsburg-based company acquired eSystems at the beginning of the year as part of the takeover of the Munich-based electronics company Katek. For Kontron, this is the second major project for intelligent wallboxes that the new subsidiary has landed in a short space of time. It was only in May that the company received approval to supply smart charging systems worth at least 200 million euros. “These major orders show: Our ’smart charging’ business unit is a central and extremely value-adding component in our portfolio,” comments Kontron CEO Hannes Niederhauser. “With this new project, we are further strengthening our growth in this forward-looking area.” Incidentally, Kontron has once again been owned by the Austrian company S&T since 2017. The purchase was co-financed by the Taiwanese contract manufacturer Foxconn, among others, which in turn acquired a stake in S&T at almost the same time. group.kontron.com

Researchers improve load-bearing aircraft structures with integrated batteries

The European research project SOLIFLY (Semi-SOlid-state LI-ion Batteries FunctionalLY Integrated in Composite Structures for Next Generation Hybrid Electric Airliners), led by the Austrian Institute of Technology (AIT), has successfully reached its final phase. The research institute reports that “significant progress has been made in the field of aviation electrification”, during the three years of development research. SOLIFLY focused on the development of special aircraft parts that perform two functions at once. Load-bearing structures in the aircraft are simultaneously capable of energy storage. The researchers explain, “the simultaneous storage of electrical energy and the preservation of mechanical strength contribute to a reduction in system weight.” The project can celebrate the development of an approach to integrate structural battery cells into aviation-grade, high-strength carbon composite components. The researchers say this is now possible without compromising their mechanical properties. The potential of this approach was demonstrated in the multifunctional project demonstrator, a high-strength, stiffened panel that the researchers chose as a representative standard component. According to the AIT, its findings proved that the integration of energy storage systems is compatible with the high mechanical requirements in aviation. The research teams involved have identified “load-bearing semi-solid-state electrochemistry” as a key element in the implementation of such multifunctional energy storage systems. The non-flammable, structural electrolyte plays a key role here. At the same time, the rest of the cell formulation must also be compatible with the structural materials and manufacturing processes recognised in aviation. Two concepts were developed as part of SOLIFLY. After the first development phase, the first concept has been created with a specific energy of 50 Wh/kg and a modulus of elasticity of 10 GPa. A series of larger, multi-layer structural battery cells were produced for the multifunctional project demonstrator. The second concept uses carbon fibres both as a structural element and as a current collector. The researchers say this variant is currently less mature, particularly in terms of electrical performance and scalability. “With SOLIFLY, we have demonstrated that integrating battery technology into structural components is possible without significantly compromising their mechanical properties,” says AIT researcher and SOLIFLY coordinator Helmut Kühnelt. “This is a crucial step for multifunctional energy storage as a key technology for future climate-neutral aviation. Through close collaboration between applied research and industry, we ensured that our developments are both pioneering and practical,” he summarised. The conclusion of SOLIFLY has informed the next focal points for continuing research work at AIT. In January this year, the follow-up project MATISSE started with a focus on developing multifunctional, structural components with an integrated semi-solid-state battery. To integrate the battery cells into the aircraft structure, the researchers want to investigate the suitability of solid laminate and sandwich structures, for example. In addition, sensors are to be built directly into the battery and the structure to measure safety and performance. ait.ac.at
