Swapnil Sawant, Founder and CEO of Tvisi Motors Limited, discusses the concept of Software-Defined Hydrogen Vehicles (SDHVs) in an interview. SDHVs differentiate themselves from traditional hydrogen vehicles by leveraging software to control critical systems independently from hardware. Sawant emphasizes the benefits of SDHVs for commercial fleet operators, including modular and upgradeable systems, optimized hydrogen consumption, and intelligent thermal and energy management. Tvisi Motors is leading the application of SDHV technology for light commercial vehicles such as delivery vans and municipal service fleets. The technology is poised to be a game-changer for fleet-based hydrogen adoption by addressing concerns about adaptability, infrastructure constraints, and upfront costs. Use cases like urban parcel delivery, utility fleets, and cold chain logistics are particularly well-suited for SDHVs due to their customizable performance capabilities. Telematics and AI are integral to the SDHV platform, providing real-time diagnostics, route planning, feature upgrades, and integration with fleet management systems. From a cost perspective, SDHVs offer superior value over the vehicle's lifecycle compared to traditional options, with lower fuel costs, reduced maintenance, and configurable service models. Sawant reveals that Tvisi Motors is preparing to launch a 7.5-tonne hydrogen truck in the United States, heralded as the world's first Software-Defined Hydrogen Vehicle in its category. This step marks a significant advancement in redefining the potential of hydrogen mobility, aiming for not just cleaner vehicles but also smarter, software-upgradable fleets designed for tomorrow's logistics.
