In Mannheim, the transportation company Rhein-Neckar-Verkehr GmbH (rnv) has put the first six all-electric city buses into everyday use. The Mobility House has contributed a custom-designed charging and energy management system so that the bus batteries, each with a capacity of 243 kilowatt hours, are always optimally charged at the lowest cost possible. By integrating a scheduling system, the software will also be able to incorporate the battery charge level, the departure times, and the bus’s energy requirements for its next tour in its optimization calculations. The batteries can also be preconditioned, which means preheating or cooling when needed to increase the maximum range.

Advantages of implementing the fleet management system from The Mobility House:

  • Transparent: The fleet management system provides an overview of the state of the charging infrastructure as well as the battery levels of vehicles in real time. This allows early detection of problems and ensures dependable operations.
  • Scalable: Additional buses and charging points from different manufacturers can be integrated into the system.
  • Economically efficient: The fleet management module prevents expensive load peaks and can prevent or reduce the need for network expansion. This means you can keep investment and operating costs low.

"The connection capacity required for our electric buses is well managed by the charging and energy management system from The Mobility House. During the day, when only one bus is charging in the depot, we can charge our buses at full capacity. At night, when all the buses are in the depot at the same time, we can reduce the charging power to one-third. It might still be fairly simple with only three vehicles, but as soon as transitioning to a fleet is under consideration, that level of control is essential."
