Voith Turbo enters e-mobility market with bus drive

Voith Turbo’s new electric bus drive has a range of 200 km

Germany’s Voith Turbo has introduced a new electric drive for buses. This marks the company’s first move into the e-mobility market.

The drive is low weight and works to maximise efficiency, rounded off with an intelligent energy management system.

Although the drive system was originally conceptualised as a prototype for a Solaris Urbino Bus, it can be integrated into vehicles from other manufacturers without restrictions.

“The achievable range primarily depends on the battery, which we acquire from an internationally renowned supplier,” said Jürgen Berger, project manager at Voith Turbo. “We are currently using a lithium-iron-phosphate battery. This battery offers the highest level of reliability, but the electric drive system is designed in such a way that it can work together with any battery technology.”

The liquid-cooled permanent magnet motor uses a high-efficiency inverter and smart energy management system and produces 2,250 Newton metres of torque and an output of 260 kW.

The compact design of the drive means that it is not only low in weight but also low in noise emissions and maintenance.

All components are cooled with water, increasing the reliability and performance and makes it possible to reduce noise emissions during operation.

The range of the demonstrator bus currently exceeds 200 km. This corresponds to the total daily operation of a conventional city bus line.

In the coming years, this range is expected to increase thanks to further developments in battery technology.
