Lithium-Ion battery technology for emobility is changing rapidly over last years and will evolve even faster in near future. Every 2-3 years there is new chemistry available that offers improved parameters including better energy density, better safety or improved power capability for faster charging. Technology change is now in many cases faster than EV products development timeframe and this implicates significant risk at the technical and commercial level for the OEMs. Battery system installed in commercials vehicle after 2-3 years of vehicle development is already not up-to-date and may have limited competition advantages. Futhermore new cell chemistries are often offered in new cell form-factor and due to that, there is no simple one-to-one cell replacement scenario available. These problems can be managed by battery system integrators by designing universal battery pack format and manage cells and modules change according to most optimized roadmap keeping whole systems homologated and compatible with vehicle over long period. This approach will allow commercial vehicle manufacturers to focus on the e-vehicle and stay competitive in the market over the long period of product lifetime.
ICPT defined the VDA PHEV-2 module format as the building block for our commercial e-vehicles battery systems. Main advantages of using standardized modules are:
· Supply chain robustness – multiple suppliers can provide 1:1 replacement
· Possibility of changing cell manufacturer without changes in the battery pack design
· Possibility of changing cell chemistry without changes in the battery pack design
· Faster adoption of new chemistries including solidstate cells
· Possibility to use different technologies (like LFP, NMC and LTO) inside one pack design.
Since 18 years, Bartek Kras has been associated with e-mobility industry. He is a specialist in designing and implementing Li-ion battery and fuel cell systems and has managed numerous projects in that field, carried out by the company since the beginning of its beginning. These projects have resulted in the implementation and commercialization of our products all over the world, including for such clients as Citroen, SAM Group, Smith Electric Vehicles, Solaris Bus & Coach, Ursus, Kiepe Electric, Voith, Temsa and KTM. He led research and development projects in international consortiums such as TAILORWELD, TOLPE and KORANET. He is an author and coauthor of a numbers patents, trademarks and unique technical solutions in area of electromobility, Li-ion batteries, fuel cells and system control. He graduated from the Faculty of Electrical Engineering at the Warsaw University of Technology, where he also gained his Ph.D. title, and completed the ICAN Institute management study (Harvard Management Course).
