    Avoid expensive load peaks within your grid by optimizing energy supply

Local energy flexibility and electrification of the mobility sector

Electromobility ranks among the key drivers of energy transition. It increases sustainability in dealing with fossil resources.

Make use of idle times of your growing electric bus fleet to ensure parallel, controlled and automated charging processes with PSIngo/EV (charging and load management)! In doing so, we take operational requirements into account, ensure that peak loads are avoided and provide transparency in terms of suitable electricity tariffs.

PSIngo optimizes any integration of charging infrastructures and enables flexibilities to be used efficiently. The tried-and-tested load and charging management monitors charging processes, including electrical power distribution. It also takes into account the consumption and self-generation of surrounding property. In combination with our demand forecasts, energy consumption is optimized and expensive peak loads in the grid are avoided.
PSIngo allows the extraction of parameters out of any charging infrastructure. Depot layout is visualized via a digital twin. It meets current requirements with freely editable reports.

PSIngo Use Cases for Local Grids

Local grids particularly benefit from intelligent network planning and control.



Charging Infrastructures

Local grids will soon face a huge demand for charging stations. Electrification of transportation alone represents only one major challenge besides robotics.



Electrified Public Transport

Due to usage patterns of local public transport, further smart grid functions are necessary despite powerful charging stations. For example, intelligent, flexible charging management helps to settle peak loads.



Controllable Ressources

In contrast to fuels, distribution of electricity can be regulated proactively in real time. This results in numerous possibilities when using large cells or virtually aggregated resources.




Advantages for local grid operators

Investments in intelligent local grids quickly pay off in times of energy transition.


  • real-time monitoring of utilization
  • detection of overload situations
  • manufacturer-independent charging infrastructure
  • documentation of processes and measures
  • transparency in favor of suitable electricity tariffs: Exploiting changes in electricity prices when planning charging
  • control of other charging infrastructures at the site (employees, visitors, fleets)

Needs-based Control

  • intelligent flexibility and charging management for charging processes and battery storage
  • controlled in parallel On-demand charging and pre-conditioned buses at departure time via value-added services
  • avoidance of overloads of mains connection and power distribution of lower-level equipment
  • Peak load management and consideration of non-controllable loads (buildings, workshops,..)
  • Battery-friendly charging

Increased Efficiency and Reduced Costs

  • higher integration of charging infrastructure
  • utilization of the existing network infrastructure up to a maximum (e.g. transformer) / avoidance of network expansion
  • integration of self-generation and battery storage
  • energy demand forecasts and procurement optimization to avoid expensive peak loads
  • smooth e-bus operation


  • for charging stations
  • for vehicles (bidirectional)
  • from sensors according to industry standards
  • to the upstream network operator to the depot management system
  • Manufacturer-independent communication
  • VDV 463 interface for circulation data and VDV261

Security in case of failure

  • switchover on error events
  • combination of both central and decentralized charging
  • PSIngo offers additional security in case of communication failures thanks to a decentralized design of technical components (OCPP gateway). Due to local intelligence, smooth operation can also be guaranteed in an emergency.
  • analogous application of the quality standards aligned to control centers

PSIngo/EV - charging management for depots

In addition to the partially self-sufficient control of electrical supply networks, the software solution PSIngo/EV offers scalable load and charging management for depots and facilities.

PSIngo/EV extends the successful PSIEbus system. It already holds depot management and PSIsmartcharging. While PSIsmartcharging is integrated in control systems, PSIngo/EV includes a separate, cloud-based solution. PSIngo enables specific control and optimization of charging processes, but also monitoring of all local grid's capacities.

Accordingly, grid-stabilizing aspects may be integrated in charging management via PSIngo. So that our grid is protected against overloads. In addition to control and monitoring mechanisms, the solution offers a variety of modules for data visualization. Not only information about the current network situation can be visualized, but also stati of charging stations and vehicle data in a user-friendly way.

Alternatively, GridConnect offers a new, cloud-based variant with PSIngo/EV. Both variants are scalable and expandable almost at will. Furthermore they supplement existing energy and depot management systems as "stand-alone" solutions - or, integrated into PSIEbus, be used as a public transport package out of the box. With our software, electric buses can now be charged in good time and to the extent of specifically planned routes. Forecasts on load and safety aspects are taken into account.
