Battery Electric Trucks can be the future backbone of the transport industry—combining maximum energy efficiency with good flexibility. Daimler Truck AG has proven, with a number of projects and products on a global scale, how capable these electric trucks can be. This presentation will investigate the special needs of batteries and cells for commercial vehicles with a special focus on cell chemistry and safety.

For Heavy duty trucks, OEMs have shown mixed interest in their cathode selection for BEV applications. In North America and Europe, companies leveraging their passenger car battery development have chosen layered-oxide cathodes, whereas others have chosen phosphate technology. China boasts the highest use of heavy truck BEV’s, with phosphate technology being the predominant choice. At Accelera, we are investigating both chemistries and have developed products utilizing both. For on-highway truck applications, we have chosen phosphates as the chemistry of choice. Here in, we will discuss the advantages and disadvantages of these two popular technologies, and the roadmaps of these chemistries.

Battery Powered Trains (BEMU) will continuously substitute diesel trains (DMU) in catenary-free rail network. Siemens Mobility will present results for aging and operation of Li-ion batteries with up to 1000 V. Charging of BEMU is carried out at overhead lines. Focus of the study will be the influence of ripple currents on battery cells as a result of DC/DC converters and 15 kV AC overhead lines.

Rail is already the most climate-friendly means of transportation, but there is still a lot of potential. Only in Germany one in four trains still run on fossil fuels, due to a lack of overhead line infrastructure. Battery electrical multiple units, such as the Stadler FLIRT Akku, offer a clean and environmentally friendly hybrid solution to this problem. The demands on the reliability and quality of trains, which are in use almost around the clock for up to 30 years, place high demands on the battery system. Here we will introduce the first series-produced battery electrical multiple unit in Germany.

For many heavy-duty applications, batteries must deliver very high-power discharge capability and a very large number of charge-discharge cycles. The IDEAL battery would provide these attributes and would also be capable of incredibly fast charge with minimal heat release, allowing almost constant up-time. Nyobolt is commercializing battery technology with the capability of fully charging in 5-10 minutes or less, with outstanding cycle life, for mining and material handling/robotic applications.

Fuel cell vehicles are expected to be a key contributor to decarbonizing transportation, particularly for heavy goods and off-highway applications. A holistic approach to system sizing can minimize cost, weight, and complexity, all whilst ensuring that vehicle capability is not compromised. This session will demonstrate how customer requirements can be used to select appropriately-sized components, and explore how the capabilities of those components are interdependent.

The electrification of high utilization use cases requires low charging times and long cycle lifetimes in order to ensure low total cost of ownership. Skeleton Technologies has developed a high-power energy storage technology capable of being charged in 60 seconds and surviving up to 50,000 cycles. This presentation will analyze the requirements of high utilization use cases and how different energy storage technologies provide the lowest TCO for these applications.

This study aims to scale down supercapacitors to a coin cell size. Various charging rates will be applied to these cells using the VMP3 potential state from BioLogic. This experimentation will simulate scenarios where supercapacitors assist batteries in rapid charging from high-rate charger devices and when they harvest excess energy from the driving system with slower charging rates. This analysis intends to reveal how supercapacitors respond to charging rates by assessing capacity levels, charge duration, and storage capabilities.

Data-driven battery degradation models increase the confidence of their predictions as more data is compilated from operation. Each time the degradation model is updated, the operation of a fleet of heavy-duty vehicles can be re-optimized (e.g., updating the charging or energy management strategy), so the warranty period of the battery is respected. As new vehicles are introduced in the fleet, transfer learning is applied to develop new degradation models.

LION Smart offers plug-and-play solutions for the integration of battery packs based on LION i3 modules (former BMW) that can be flexibly adapted to a wide range of requirements. With production-ready and modular technology, battery packs can be integrated for all types of applications – from small cars to commercial vehicles to stationary energy storage. Under “Made in Germany” LION offers automotive high quality, road proven products on which customers can benefit from great development and long lifetime. Long-term availability" can be ensured through gradual further development while retaining the mechanical, thermal and electrical interfaces (backwards compatibility).

The Mercedes-Benz Trucks GenH2 Fuel Cell Truck recently made headlines for completing a remarkable journey, covering a record-breaking 1047 km on just one hydrogen tank. This success is attributed to an efficient system design, particularly the high-voltage battery and other essential components. The talk gives an overview of the overall GenH2 truck system with a special focus on its battery design and highlights the differences to battery-electric trucks.

Heavy-duty electrification is dependent on lighter, higher C, and cheaper battery cells. There will be no change before the vehicles may charge on publicly-available fast chargers. Business and logistics chains will remain, and the same transport companies will transition into a carbon neutral transport economy. Or is it the other way around? Join for an analysis made to make you think.

Limiting the depth of discharge (DOD) allows you to achieve a greater number of cycles, but limits the useful energy in one cycle. The publication examined the hypothesis that it is possible to extend the lifetime and increase the discharge energy (higher vehicle mileage) at the expense of an initial limitation of the discharge depth (shorter range at the beginning of use), i.e. a shorter vehicle range at the beginning of the vehicle's life allows for a much higher vehicle mileage to be achieved.

The SAE J2990 Task Force has developed standard practice for documenting Emergency Response Guides for EV and fuel cell vehicles. Field incident investigations, first responder feedback, and recent research has provided further guidance for tools and resources needed as battery systems scale up for HVOR markets.

Electrovaya’s infinity batteries provide superior performance over conventional lithium-ion battery solutions, and are exceptionally well-suited for demanding and mission-critical applications where longevity and fire safety are critical metrics. This technology offers superior battery quality allowing for an outstanding combination of performance, safety, and longevity. This superior performance was achieved through years of R&D, extending the battery’s lifetime and setting the industry standards (End of Life ~14000 cycles, equivalent to 3.5 million mile for a 250-mile range).

While lithium-ion batteries are prevalent in our lives, they are made safe through the encasement of the battery, combined with temperature sensing and cycle counting. This strategy is effective for electronics and small mobile applications, but impractical for large systems. Large systems require accurate measurement of a battery‘s “state of health," so that it may be isolated and replaced before failing.
