Against the backdrop of making the mobility of the future sustainable, there is now a clear trend towards e-mobility. Municipal company fleets and vehicle fleets are being electrified and public and private charging infrastructures are being expanded.
Support for electromobility requirements
The increasing number of electric vehicles - and therefore more charging stations - can lead to grid bottlenecks and outages due to simultaneous, uncoordinated charging. If a grid expansion is not feasible as a solution to the problem, PSIsmartcharging offers the ideal, future-proof platform for the intelligent control and optimization of charging processes. In addition to grid-stabilizing aspects, the system also takes into account operational requirements and economic factors
- in bus depots (public transport)
- for fleet operators
- in parking garages and public charging parks.
Smooth electric bus operation in our cities
In public transport, PSIsmartcharging works directly with depot management systems to ensure that electric buses are charged on time and to the optimum extent for their planned routes, taking safety aspects into account. The power grid is constantly monitored and, in the event of imminent overload or restrictions in energy supply, the power is redistributed so that the grid status is stabilized again.
In the future, electricity price changes can be flexibly taken into account in charging planning. Long-term additional income can also be generated by offering balancing power. The integration of additional battery storage at the depot to increase flexibility is also conceivable.

Typical users
Switching line
The personnel in the control center have process sovereignty and must always be informed about all interventions in the network. This applies in particular to switching and fault clearance activities. The personnel in the field send digital feedback to the control center and relieve the control center personnel by “missing” phone calls, which in turn reduces the background noise in the control center.
-
Relief
Communication mainly takes place digitally, the role of the coordinator is eliminated and the noise level in the control room is reduced.
-
Safety
The switching engineer can create switching sequences and set them up so that deviation is not possible. Even if the personnel in the field are authorized to carry out operations autonomously, the control system checks and visualizes each switching step and the switching engineer is informed of the current booth of switching operations at all times.
FAQ'S
How does vehicle monitoring work with PSIsmartcharging?
On the route, the vehicle continuously reports (e-bus actual data) to the depot management. This includes, among other things
- Battery capacity (SOC, State of Charge)
- Vehicle ID
- Kilometre booth
- Energy used
The depot receives operationally relevant data (vehicle master data, service and timetable data) as well as environmental and weather data (interface to a weather service) and data from the operations control system. This is followed by a continuous comparison of the charge status and remaining range with the open rotations, taking into account the above-mentioned vehicle master and rotation data and operational requirements, e.g. supply and workshop orders. This data forms the basis for the forecast calculation of the energy requirement for the next round/trip/route by PSI's own AI-based optimization core Qualicision. This results in a prioritization of the charging processes of the e-buses with the aim of only achieving the required charge level for the planned rounds (in the event of bottlenecks). Finally, the depot sends this priority list to the LMS (PSIsmartcharging) based on the operational and e-bus data via the common VDV 123 standard interface.
Is collected data archived?
Yes, generated and received data from the vehicles in the power grid and the connected equipment and charging infrastructure are archived in the individual subsystems. It is possible to integrate and evaluate the data for reports and flexibly configurable statistics and reports.
