Charging and Load Management Software

With the growing number of electric vehicles (EV) and charging points, the available charging power for charging sessions must be coordinated in an intelligent way. With our charging and load management backend vCharM you can operate entire charging parks at high availability. Once a charging station has been connected to vCharM, each charging point can be conveniently configured, monitored and controlled.

Our scalable feature based software can be configured depending on the customers use case, while staying completely independent from charging station manufacturers.


  • Charging station manufacturer-independent solution using standardized communication protocol OCPP 1.6J, OCPP 2.0 and OCPP 2.0.1

  • Optimized for fleet operators, e.g. bus depots, special vehicle fleets, company vehicle pools, car parks and other electric vehicle fleets

  • Optimized load management for vehicles with and without smart charging according to ISO 15118 and DIN 70121

  • Connection to fleet management system for automated exchange of vehicle data

  • Vehicle authorization via RFID, Plug&Charge (PnC), Autocharge and other methods

  • Control of vehicle preconditioning via Value-Added-Service according to VDV 261

Test vCharM for 15 days!

You have several charging points and want to operate them at the same time? Then you need a charging and load management backend to efficiently supply all charging points and the connected e-vehicles.

Test our charging station management system vCharM and get access to the full functionality for 15 days! Experience our intuitive user interface: For example, configure and monitor multiple charging stations, compare the effects of different charging strategies or discover the numerous reporting options.

You can also use vCharM to test the compatibility of the OCPP interface of your charging station with our manufacturer-independent backend.


Manage Charging Stations in Fleets, Depots and Apartment Complexes

Charging several electric vehicles at the same time leads to challenges for the electric infrastructure of your company or property. A charging and load management backend helps you to avoid a cost intensive expansion of the grid connection as well as high electricity costs due to peak loads. With our independent software solution, any kind of charging station or EV can be connected to our backend due to the standardized OCPP communication protocols. 

The charging station management system is particularly suitable for the operation of EV fleets and charging points for instance in residential car parks, vehicle pools or depots. vCharM can be used as a standalone software or integrated into an existing EV fleet management system.

Verify the Preconditioning in Electric Buses

To implement the preconditioning of electric buses as described in VDV261, it is necessary to exchange information directly between the electric bus and the backend independent from the charging station. To test the implementation of this interface and its functionality at all levels, the Value Added Service Testing in vCharM can be used. Use vCharM to test and verify the preconditioning processes in your electric vehicles. Tests can be made at ECU level, in the vehicle or in combination with the charging station.

Load Management

Manage load consumption dynamically with configurable charging strategies

Load management is required at the latest when the total power of the charging stations exceeds the available installed power. However, costs can also be saved beforehand by avoiding peak loads at individual charging stations. The operator decides on the prioritization of the charging processes by selecting the charging strategy that suits best.

Charging Station Control

Monitor, configure and control charging stations via OCPP 1.6J, OCPP 2.0 and OCPP 2.0.1

Charging points can be configured, monitored and controlled via the user interface. Guided dialogs support the operator in his various tasks. In case of problems with a charging session, the operator is notified and supported in failure diagnosis. Communication with the charging station is via the manufacturer-independent OCPP protocol.

Vehicle Preconditioning

Monitor and control individual vehicle preconditioning via the implementation of Value-Added-Services

The control of the preconditioning of electric buses was standardized by the Verband Deutscher Verkehrsunternehmen (VDV) as a Value-Added-Service. vCharM supports the VDV 261 specification and offers various control interfaces.

Vehicle Authorization

Manage and verify vehicle authorization requests

Various methods are available for the authorization of charging sessions. vCharM supports established technologies such as RFID chips, Autocharge. Plug&Charge according ISO 15118. 


Generate and analyze reports with statistics of finished charging sessions

Reports with statistics on completed charging operations can be created for various purposes. Pre-defined reports can be customized and exported if desired.

Fleet Management

Automate data exchange with your fleet management system

Existing fleet and depot management systems can be integrated via an automated data interface and used for optimized load management or pre-conditioning control. Fleet and depot management systems can use vCharM data for their own purposes, e.g. for availability display. Further tools can also be integrated, such as a maintenance ticket system.


Log transactional data of charging sessions in law-conform manner

Meter readings are centrally recorded and processed. The data is made available for billing transactions. The meter readings can be protected against manipulation by a digital signature in order to meet the requirements of the new calibration law.

User Interface

Use vCharM from a browser-based frontend with a modern and intuitive user experience

A browser-based interface allows the user access to all functions. The views are adapted to the respective user role. The interface is available in different languages. An HTTPs connection secures the access.

System Architecture

The vCharM architecture provides a REST interface for the integration into other management systems. The exchanged data can be used to optimize the charging sessions and the operational business.

Hosting Variants

vCharM can be operated on-premises or in the cloud, depending on the customer requirements. It is even possible to combine the benefits of both models and operate vCharM in a hybrid mode.

Supported Standards

  • OCPP 1.6J, OCPP 2.0 and OCPP 2.0.1
  • VAS/VDV 261
  • ISO 15118
  • DIN 70121
  • IEC 61851
  • IEC 63110 (planned)

Smart Charging with ISO 15118

Example of an ISO 15118 message with a PMaxSchedule. The maximum power profile is calculated by vCharM for every charging session and transmitted to the charging station via OCPP. The charging station uses ISO 15118 to limit the power consumption according to the received profile.

The protocols ISO 15118 and OCPP 2.0 provide a comprehensive interface to control the power consumption of charging procedures for electric vehicles. vCharM uses these mechanisms to adhere to physical limits of the infrastructure as well as to guarantee the ideal scheduling of charging sessions.
A load management algorithm depends highly on the charging environment and the customer needs. vCharM offers different algorithms, each optimized for a specific use-case. This enables the usage of vCharM in different application areas, e.g. for bus depots, special vehicle fleets, company vehicles pools, car parks and other EV fleets.
