2025-07-17 The new VEDS 1.5: Bus manufacturers and operators benefit from groundbreaking developments

Moreover, the new inverter system with integrated DMU meets the relevant requirements of the functional safety standard ISO 26262 for applications up to ASIL C and is based on an AUTOSAR software architecture. Another key advantage of the new VEDS 1.5 is the system’s modular approach. Voith relies on a universal inverter with a voltage range of 560 to 850 V that covers both electric motor variants – i.e., HD (heavy duty) and MD (medium duty). Thanks to the smaller and lighter design, the inverter is also reducing the weight without compromising efficiency. With a system weight of just 22 kilograms, it achieves a peak power of up to 390 kW.

Voith also attached particular importance to developing a modular system that is easy to install and service. Automotive-compliant connections, an integrated diagnostics unit and a new I/O gateway for extended charging functions accelerate and simplify the installation and maintenance of the new VEDS 1.5.

As a partner and pioneer for integrated electric mobility solutions, Voith therefore continues to support the transition to climate-friendly mobility – as always by being reliable, innovative and sustainable. The rigorous ongoing development of the proven VEDS once again testifies to the company’s outstanding expertise in the bus segment in particular.

“Whether our customers are bus manufacturers or fleet operators, the cybersecurity features, compactness and flexibility of the new VEDS 1.5 gives them a powerful, future-ready modular drive system that meets the most exacting technical and safety standards,” Gundel stresses.

Depending on the application and requirements, VEDS 1.5 comes in two variants: small scope or extended scope. The small scope version consists of the basic components of the modular system, i.e., electric motor plus new inverter system DIS with integrated DMU. The extended scope version offers additional components on request, e.g., a new power distribution box (PDB) an interface to the battery and central distribution box to supply energy to all electrical consumers, auxiliary inverter, HV and LV cables, Central Electric Interface (CEI) for communication with the vehicle, and a charging control unit.
