ABB Motion is advancing public transportation electrification with its latest innovations aimed at improving efficiency, safety, and sustainability. Key products include the Traction Battery Pro Series, the AMXE250S traction motor, and the HES580 mobile inverter, all designed to power the next generation of electric buses.
The Traction Battery Pro Series features lithium-titanate oxide (LTO) chemistry, delivering ultra-fast charging capabilities – up to 80% charge in under 10 minutes—along with long cycle life exceeding 20,000 cycles. The modular, liquid-cooled design allows customization of capacity and voltage configurations to meet diverse fleet requirements while offering robust thermal stability and an integrated remote monitoring system to optimize performance and reduce total cost of ownership.
The AMXE250S is a compact permanent magnet synchronous motor engineered specifically for heavy-duty electric vehicles, delivering high torque across a wide speed range. With liquid cooling and deep integration with ABB’s inverter technology, it offers exceptional efficiency, durability, and low harmonic losses, ensuring smooth and reliable operation in urban transit conditions.
The HES580 mobile inverter utilizes next-generation three-level converter technology that reduces harmonic losses by up to 75%, lowers voltage stress, and extends motor life for public transportation vehicles. Internal tests pairing the HES580 with the AMXE250S motor have demonstrated energy savings of about 6.3% compared to traditional two-level inverter systems during real-world bus duty cycles.
Together, these technologies form a highly integrated powertrain ecosystem that supports the transition to zero-emission public transport by enhancing vehicle efficiency, operational flexibility, and sustainability, underscoring ABB Motion’s commitment to accelerating fleet decarbonization and enabling future-ready electric bus deployments.
This product suite is already undergoing validation with multiple OEMs, with series production planned to start in 2026 at ABB’s European manufacturing facilities.
