From charging delays to seamless mobility – RTU researchers redefine battery use in electric transport

As electric mobility continues to expand rapidly across Europe, challenges such as long charging times, high costs, and sustainability concerns remain barriers to wider adoption. Researchers from Riga Technical University (RTU) are contributing to addressing these challenges by participating in the international EVBAT project, implemented with the support of EIT RawMaterials. The project aims to develop a sustainable, swappable battery system specifically designed for light electric mobility.

At the centre of the project is HYBA’s lightweight, modular battery unit – the POD – which allows users to replace a depleted battery with a fully charged one in just minutes. Instead of waiting for a vehicle to charge, users can quickly swap batteries at dedicated stations, ensuring continuous use.

"EVBAT is highly relevant now because the EV market is rapidly growing while still facing issues like long charging times, high costs, and limited infrastructure," Dr. sc. ing. Nidhiben Patel, Lead Researcher at Riga Technical University and a member of the EVBAT project team explains. "At the same time, stricter climate targets and concerns over critical raw materials make low‑carbon, circular battery solutions essential."

Designed for sustainability and circularity

What makes EVBAT distinctive is not only the swapping functionality, but also the battery design itself. The POD system is modular and based on a weldless assembly concept, allowing easier repair, disassembly, and recycling compared to conventional battery packs.

The system integrates advanced battery management and telematics for real-time monitoring, ensuring safety and efficient lifecycle management. Once battery performance declines, individual cells can be reused in second‑life applications or recycled, reducing both waste and the need for new raw materials.

"The environmental performance of a battery is determined not only during use, but across its full life cycle," Nidhiben Patel highlights.

This life-cycle approach is supported by researchers from Riga Technical University, who evaluate the solution from raw material extraction to end‑of‑life. The goal is to ensure measurable impact, including up to 30% reduction in CO₂ emissions across the battery value chain.

Spēcīga sadarbība kā attīstības pamats

«EVBAT» projekts apvieno daudzdisciplināru Eiropas partneru konsorciju, kas aptver visu bateriju un mobilitātes vērtības ķēdi. «HYBA» (Itālija) vada projektu un izstrādā bateriju tehnoloģiju, «Vent Moto» (Itālija) nodrošina tās integrāciju elektriskajos motociklos, «LEVOX» (Spānija) izstrādā bateriju maiņas infrastruktūru, savukārt «SE&C IKE» (Grieķija) koordinē projektu un komunikācijas aktivitātes. Rīgas Tehniskā universitāte (Latvija) veic zinātnisko analīzi, īpašu uzmanību pievēršot ilgtspējai un ietekmei uz vidi.

RTU VASSI komandu vada tenūrprofesors Dr. sc. ing. Francesco Romagnoli, komandā darbojoties arī vadošajai pētniecei Dr. sc. ing. Nidhiben Patel un pētniecei Mg. sc. ing. Amrutha Rajamani.

Projekta komanda jau ir sasniegusi vairākus būtiskus rezultātus, tostarp izstrādājusi un attīstījusi funkcionējošu bateriju prototipu un integrējusi to transportlīdzekļa demonstratorā.

«Konsorcijs apvieno inženiertehniskās, infrastruktūras un ilgtspējas kompetences, lai izveidotu resursu ziņā efektīvu risinājumu elektriskajai mobilitātei,» norāda RTU VASSI komanda.
