ViriCiti is in the process of enabling 2 of the largest Smart Charging projects for electric buses in Germany, with 45 chargers at Stadtwerke Münster, and 42 chargers at Offenbacher Verkehrs-Betriebe GmbH. Out of these, currently there are 29 live in Münster and 24 in Offenbach, with the rest scheduled to come online soon.
Growing charging costs
With a growing fleet of electric buses, both public transport operators were facing a substantial increase in charging costs, mainly associated with peak demand charges.
Furthermore, both transit companies must work around existing grid limitations and minimize as much as possible the costs associated with upgrading their connections to the electricity network.
Solving the challenges
To help them overcome these challenges, both operators have chosen the ViriCiti Charge Station Monitoring and Smart Charging solutions.
With powerful features such as Remote Monitoring and Resets, Group Limit, Scheduled Group Limit, and Manual Prioritization, we can help our customers stay on top of their monthly charging costs while minimizing the investment in new and expensive grid upgrades.
In addition to that, we also provide useful Energy and Uptime reports, which allow the fleet operators to better understand their entire charging process and optimize their future fleet investments.
Furthermore, Offenbacher Verkehrs-Bbetriebe will also make use of the ViriCiti preconditioning feature which makes sure that vehicles are preheated, cooled down, or air-conditioned while they are still plugged into the chargers in the depot. This ensures that electric buses can start their shift with a full battery, maximum range, and a comfortable temperature.
A close collaboration with SBRS GmbH
To implement our Smart Charging solutions, we had the pleasure of collaborating closely with SBRS, who provided the charging infrastructure for both these projects.
To make sure we can provide a reliable, scalable, and future-proof solution for our customers, all chargers from SBRS have been updated to run OCPP 1.6, which is a free, open-source communication standard for EV charging stations and network software companies.
This is yet another testament to the fact that both companies are committed to interoperability.
For these projects, the company SBRS from Dinslaken provided various depot chargers as well as fast chargers of the SEB series to the customers and networked them accordingly. The patented fast chargers of the SEB series are available with up to 1MW charging point power. They are characterized by their high efficiency, water-cooled and low-noise design.
Through the connection to the ViriCiti system, load requirements such as temporary power reductions of the utility company can be transferred directly to the SEB system technology.
The systems from SBRS are generally used in different environments and are able to fit each requirement, e.g. limited space available in urban areas as well as in bus depots. In terms of upgradeability, the SBRS devices are excellently equipped for the future and leave nothing to be desired.
