Efficient integration of electric buses: PSI Transcom and The Mobility House implement VDV 463

December 01, 2020|Munich, Zurich

  • PSI Transcom and The Mobility House are implementing the VDV interface 463, which enables the integration of load management systems for electric buses into the depot management.
  • Both companies are committed to standards and the greatest openness possible, so that customers have full flexibility in their selection of buses as well as hardware and software.
  • The intelligent charge control of ChargePilot®, the Charging and Energy Managament system of The Mobility House, can be combined with any depot management system via VDV 463.
Electrified bus fleet

The technology company The Mobility House and PSI Transcom, a subsidiary of PSI Software AG and Germany's third largest software house, are working together on a digital interface to advance the electrification of bus fleets. The jointly implemented VDV interface 463 enables the combination of a charging and energy management system with the depot management system PSIebus. The functionality has already been tested and is intended to make it easier for bus fleet operators to switch to electrically powered vehicles in the future.

PSI Transcom was the first provider to develop such an interface in a project, which is unique in the country to date, with Hamburger Hochbahn AG, which already actively operates more than 60 electric buses. This is used to exchange important data between the systems for the smooth operation of electric buses: among other things, the battery level at the time of arrival as well as the desired target SoC (State of Charge), which guarantees the necessary range with a flexible allocation of the buses to suitable rounds. Additionally, information can be passed on for pre-conditioning if the bus is meant to be cooled in summer or heated in winter before departure. Using this data, the connected systems control and monitor the individual charging processes and ensure that each bus is ready for operation at the start of its service.

The interface will soon be published as VDV 463. PSI Transcom and The Mobility House are currently pooling their development competencies and working in partnership to provide their customers with the best product package possible. On the one hand, this will ensure that ChargePilot®, The Mobility House's Charging and Energy Management system, which already helps to charge more than 100 buses internationally, can communicate with various depot management systems via the upcoming VDV standard 463 and can be combined with them as desired. On the other hand, it also enables the PSIebus depot management system from PSI Transcom to be compatible with different load management systems.

PSI Transcom as well as The Mobility House rely on the greatest flexibility possible in the standardization of the interface so that the systems harmonize with a wide range of electric bus models as well as charging hardware and software of various manufacturers. This guarantees fleet operators the greatest possible flexibility in selecting their products.
