The Traction Battery Pro Series was designed for safety, longevity, and operational flexibility. The system supported ultra-fast charging, optimized total cost of ownership, and integrated seamlessly with ABB’s drivetrain ecosystem to accelerate fleet decarbonization.

The AMXE250S traction motor, a compact permanent magnet synchronous motor built for heavy-duty electric vehicles, “is engineered for high torque across a wide speed range. The motor offers exceptional efficiency, supported by ABB’s deep drivetrain integration expertise”, in ABB’s words.

Finally, the HES580 mobile inverter, a next-generation three-level inverter, is said to reducing harmonic losses by up to 75 percent, lowering voltage stress, and extending motor lifetime. Internal tests pairing the HES580 with the AMXE motor under the UITP SORT 2 duty cycle – which replicates real-world city bus operation – indicated energy savings of around 6.3 percent compared with conventional two-level inverter technology, ABB states.

The bus industry’s smartphone moment

On 18 March 1895, at 6:25 in the morning, the world’s first motor bus line opened between Siegen, Netphen and Deuz. The vehicle was a Benz Landauer. It had eight seats, a one-cylinder engine of five horsepower, and fifteen kilometres of bad road ahead of it. On the steepest hill, the passengers had ...
