White Paper

Electric mobility is on everyone's doorstep and the demand for charging stations is growing. However, charging is no longer limited to the wallbox at home. In the future, electric vehicles will take over all areas of mobility and increasingly influence our private and business lives.

But many grid connections are not designed for the additional power consumption by EVs. As the number of charging sessions increases, it becomes important to manage and prioritize them to ensure that the respective vehicles are fully charged in time for their use, especially if the EVs are used commercially.

In this white paper you will learn:

  • How load management can be used to build and expand charging infrastructure even with existing connections
  • How charging stations can be configured and managed easily with a back end system
  • Which strategies can be defined for charging depending on specific use cases

When many electric vehicles need to be charged at the same time, load management plays a crucial role to avoid load peaks. However, the load management algorithm requires a lot of different information sources to calculate the optimal set of charging profiles.

In some scenarios the information which vehicle is connected to which charging station is mandatory. If there is a authorization process related to the vehicle the identity of the vehicle is already available.

If there is no authorization used, the identification of the vehicle is not possible.
As a solution, we will describe possible methods for the identification of a vehicle with OCPP.

A method if supported by both charging stations and charging station management systems that ensures interoperability without any further project-specific adaptations.

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

A browser-based interface gives the user access to all functions. The implemented role management allows to adapt the views to a respective user role, such as operator or administrator. The user can only access features, which are granted for the configured role.  Moreover, the interface is available in different languages and as a white label version. An HTTPs connection secures the access.

Manage your charging stations on the go with the vCharM app

The mobile vCharM app provides the most important features for charging station operators. Downtimes are reduced, since the charging infrastructure can still be monitored via the app when the CPO does not have access to the regular user front end, e.g. during maintenance work.


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. An interface to an energy management system (EMS) is used to optimize the load management. Therefore, no fixed limits and additional reserves are necessary for charging sessions, but the charging power depends on the actual available power. 

Charging Station Control

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

Charge 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. Additional documentation of the charging infrastructure, e.g. schematics of the electrical setup, can be uploaded and stored in the user front end. This is especially helpful for charge parks with charging stations from various brands. 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 and Plug & Charge according to 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 (REST and VDV 463) and used for optimized load management or pre-conditioning control. The open and standardized interfaces ensure a high interoperability between charging station and depot management systems. Fleet and depot management systems can use vCharM data for their own purposes, e.g. the planned charging sessions for the fleet can be visualized. 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.

Certificate Management

Management and validation of contract certificates and charging station certificates

Enable vehicle and charging station authentication and charging authorization by Plug & Charge according to ISO 15118. Securely exchange contract data for clearing and invoicing between the vehicle and the back end.

System Architecture

The vCharM architecture provides a REST and VDV 463 interface for the integration into other management systems. The exchanged data can be used to optimize the charging sessions and the operational business and also for cost tracking and billing.

Hosting Variants

vCharM can be operated on a local hardware device and in the cloud. For cloud usage, the hardware device can establish an internet connection between the charging stations and the cloud. The device can be supplied by Vector; please contact us for more information.

Supported Standards

  • OCPP 1.6J, OCPP 2.0 and OCPP 2.0.1
  • VAS/VDV 261

Smart Charging with ISO 15118 and OCPP 2.0.1

The protocols ISO 15118 and OCPP 2.0.1 provide a comprehensive interface to control the power consumption of charging procedures for electric vehicles. With vCharM, you benefit from the latest OCPP version 2.0.1, including improved transaction handling and increased security. Security is also enforced by TLS encryption of the whole communication, enabling for example secure firmware updates and authentication. In addition, support for ISO 15118 with regard to smart charging requirements, e.g. for Plug & Charge, is implemented in OCPP 2.0.1. Besides, OCPP 2.0.1 offers device management and thus an improved possibility for the customer to retrieve and define configurations and also to monitor a charging station.

Load Management

Static load management
With static load management, a total power output is defined for all charging stations, which is distributed to all charge points. Unless a special prioritization is defined, every vehicle is provided with the same charging power, no matter when it arrives. So if more vehicles are added to the charging gradually, less power is available for each individual vehicle. 


Dynamic load management
With dynamic load management, the total charging capacity is adapted to the power consumption of the building. If less electricity is consumed there, more is available for charging the electric vehicles and vice versa.  


Schedule-based load management
Schedule-based load management integrates departure times, required power and other vehicle priorities into the distribution system, so that electric vehicles that have to leave the charging park earlier can be charged more quickly.  


Individual charging strategies
Would you like to design your load management individually and develop your own charging strategy? We offer pre-configured charging strategies, e.g. for charging bus depots and for employees charging at their workplace, or advise you on the development of your individual charging strategy.
