Knorr-Bremse subsidiary key partner in electrification of bus fleets

Kiepe Electric, a subsidiary of Knorr-Bremse AG, is the global market leader in braking systems and a leading supplier of other subsystems for rail and commercial vehicles. Mass transit authorities in Milan and Modena rely on Kiepe Electric traction systems to power their new Solaris IMC buses.

Kiepe Electric is supplying a full range of traction power converters, motors, high-performance 45 kWh lithium titanate oxide traction batteries, and auxiliary systems. “The focus is on our pioneering in-motion charging concept,” explains Dr. med. Asum. “While the bus is in motion, the system transfers up to 500kW of energy from the overhead line to the modular traction battery. “The Milan buses each have a range of up to 24 kilometers (15 miles) – with no need to spend long periods of time recharging at each end of the bus route. Their smart energy management systems also support the catenary network via the high-performance battery in each bus.

Kiepe Electric’s newly developed roof-mounted equipment housing (DGG) for 12-meter, 18-meter and 24-meter buses. The latest generation of traction equipment – especially the on-board auxiliary power converters – means that installations and bus designs can be much more compact.
