All about VDV 261

Anyone familiar with the field of public transport has certainly heard of the VDV 261 guideline. But what is VDV 261 actually?

What is VDV 261?
VDV 261 is a technical document published by the Association of German Transport Companies that describes how to ensure the data exchange necessary for the preconditioning of vehicles. This means, for example, that the temperature in the bus can be adjusted for passengers even before the bus departs from the charging station. And not just for one bus, but automatically for all buses.

Preconditioning leads to a longer range of battery-powered vehicles, since the energy needed to heat up or cool down the vehicles for the first time is not taken from the battery, but from the power grid. In short, VDV 261 increases comfort, increases range and saves time and therefore money, as processes no longer have to be done manually but are automated.

How does VDV 261 work?
VDV 261 describes how the value-added services of ISO 15118 must be used to automatically precondition vehicles during a charging process. Intelligent charging management enables so-called preconditioning, basically a “preparation” of the buses, via the existing charging infrastructure. There are various options for this, e.g. heating, cooling, ventilating. As soon as the electric bus is connected to a charging station, the data sent can be used to determine precisely whether preconditioning is required and, if so, in what form, so that the vehicle is ideally prepared at departure time. The challenge here lies in the smooth communication from the vehicle via the charging station to the charging management, as this communication chain must be encrypted and coordinated with all parties involved.

What is the benefit of VDV 261?
The VDV 261 interface helps to optimize planning and processes and to minimize potential risks. Because heating e-buses that are not currently connected to the charging station consumes a lot of energy and has a negative impact on the range. The bus is connected to VDV 261 during preconditioning at the charging station – so there is no need to worry about range. Passengers also experience more comfort as the temperature can be optimally prepared.

In addition to VDV 261, the standard VDV 463 is recommended – more information can be found at: https://www.carmedialab.com/en/vdv-463-makes-charge-planning-easy/.

Aachen’s “ASEAG” goes electric!

Charging in the future with MOBILEcharge
The “Aachener Straßenbahn und Energieversorgungs-AG“, or „ASEAG“ (short for Aachen Tramway and Energy Supply Company), is soon charging their electric bus fleet with MOBILEcharge. Up to 150 charging points will be created in the ASEAG depot, which will work with VDV 463 and VDV 261, among others.

By the end of July 2023, milestones such as the establishment of a server instance, implementation of network requirements, certificate creation and provisioning, configuration of charging stations, communication tests and vehicle tests will be completed.

We are very much looking forward to this collaborative project!

White paper:
How to implement charge management successfully

Benefit from our experience and implement an intelligent charging concept in your e-bus fleet. The following three factors will bring your project to success: Taking an iterative approach, maintaining close communication between those involved, ensuring that system components are interoperable, and having an experienced partner on hand will all play an essential role.

With its software application MOBILEcharge, CarMedialab is involved in a range of projects since 2019. More and more transport companies start to realize that managing a fleet with this new type of refuelling is so complex that it requires the help of an intelligent charging system.

Are you considering a transition to electric power for your bus fleet?

Good bus charging management is compatible with existing systems

Future-proof charging management thanks to VDV-Normen
Users of our charging management system MOBILEcharge benefit from the interoperability of the software to efficiently charge many electric buses. But what does that mean exactly?

Interoperability generally means that a system can work together with other systems. If the system’s interfaces are open, collaboration can work with two or more programs or systems. Thus, multiple systems can be integrated without problems of access or implementation.

Interoperability enables the integration of existing systems

At Rhein-Neckar-Verkehr GmbH (rnv) for example, e-buses, as well as passenger cars, are charged at four depots with over 100 charging points. Various interfaces ensure optimal functionality: VDV 463 between charging management and depot management system (DMS) at the customer’s site and VDV 261 for communication between charging management and vehicle to control preconditioning (Interior and battery are tempered in time). Compliance with these VDV standards enables a high degree of interoperability. GoRaleigh based in the USA also controls and monitors the charging activities of the e-buses with MOBILEcharge in connection with the control centre. Changes can be made permanent so that charging can always be carried out in a cost-saving manner.

Conveniently charge and monitor e-buses
Through our charging management system MOBILEcharge, all charging processes can not only be primarily controlled but also monitored in real-time. Charging with reduced amperage increases battery life while lowering overall energy demand.
