Work Package 1
Scenarios & Requirements


This work package will define baseline requirements for the development of eBus charging systems derived from opportunity and depot charging use case scenarios. As part of this work package the following objectives are taken into account:

  • Definition of main eBus application scenarios (Use Cases)
  • State of the Art (Technology and standards evaluation)
  • Architecture and interface requirements
  • Connecting factors for electric bus and charging infrastructure operations

Work Package 2
eBusCS Architecture


Based on the work conducted in WP1 the overall architecture of the eBusCS charging system, its associated technologies and the relevant standards will be defined within the framework of this work package. It is intended to reuse and build upon existing and standardized solutions from the field of electric passenger vehicles as much as possible in order to reduce associated costs for development and testing. Hence, this work package takes the following objectives into account:

  • Definition of the overall architecture of an eBus charging system
  • Specification of electrical & mechanical interfaces
  • Specification of the control interface
  • Specification of the connection of ancillary systems

Work Package 3
Implementation of the eBusCS Charging System


The aim of this work package is to implement an evaluation environment, which allows to validate eligible technologies and test corresponding interfaces. As part of this process the following objectives are taken into account:

  • Development of electrical components
  • Development of communication components
  • Implementation of the evaluation system (1. Phase)
  • Implementation of the demonstration system (2. Phase)

Work Package 4
Test System for the eBusCS Charging System


Development of a test system is seen crucial for enabling vendor-independent interoperability between charging infrastructures and electric buses. In order to achieve this overall goal the following objectives are taken into account:

  • Specification of conformance testing environment for eBus charging systems
  • Adaptation and extension of eNterop technology platform
  • Implementation of the test system
  • Testing of evaluation and demonstration components

Work Package 5
eBusCS Management System


A management system is needed for asset management of charging infrastructure as well as charging process integration in order to optimize energy usage particularly in depot charging use cases where operational costs need to be minimized. As the power demand will have a significant impact on corresponding distribution grids and their associated operation costs a management system is seen as necessary enabler for the introduction of electric busses. In the context of this work package the following objectives are therefore taken into account:

  • Management system architecture and interfaces
  • Component development and associated interfaces
  • Test systems for management system interfaces
  • Evaluation system / Prototype for the management system

Work Package 6
Standardization and Communication


The main goal of eBusCS is to support a standardized solution approach for eBus Charging Systems in close cooperation with different technical committees like ISO/IEC as well and application & user forums like VDV and UITP. Furthermore SMEs are supported in the product development process through workshops, test events etc. In order to achieve this overall goal the following objectives are taken into account:

  • Technical standardization
  • Application standardization
  • Organization and execution of workshops, Testival and external cooperations
  • Public relations and publications
