Demo Project 8: eMobility as a Service

Enabling the future: Seamless integration of E-mobility as a Service within a Positive Energy Block.

Vision (DP08) in a nutshell

DP08 deployed an e-mobility as a service (eMaaS) platform, which incorporates Electric Vehicles (EVs), Electric Bikes (E-bikes) and public transport. New technologies to enable cost and energy efficient smart charging have been implemented and are connected with a communication and trading platform. This will encourage the use of EVs and E-bikes and demonstrate the potential for trading between EVs, buildings and the grid, and incorporating charge/discharge connection points.

Problem addressed & specific objective

Global energy use has two major vectors in (i) buildings, which have approx. 40% of total primary energy demand and (ii) transportation, which account for approx. 28% of total primary energy demand. With respect to transportation, the anticipated number of Electric Vehicles (EVs) are expected to be more than 90% of all cars by 2050. Integration of eMobility poses new challenges in the movement towards MaaS in general. When using EVs as “batteries” it becomes important to ensure that the availability of the vehicles is kept to a satisfactory level for the mobility users. A large number of EVs require intensive charging, but can also participate in a distributed positive energy block (DPEB) by returning energy that is assumed not to be needed, thereby reducing that EVs’ range temporarily. Such returned energy from EVs can be used to “top up” the DPEBs energy needs. 

By integrating modern distributed ledger technology-based/fee-less microtransactions into vehicles or chargers, it is possible to transfer any amount of energy, while at the same time ensuring secure payments from machine to machine (e.g. from vehicle to DPEB). As such, V2B can be a means for peak shaving, as an emergency backup for a building, and for grid load balancing.

eMobility as a Service platform :

The eMobility as a Service Platform is a mobility solution that enables transport from A to B utilising either public transport, personal transport by shared EVs and/or EBikes, or a mixture of several/all transport modes. The platform collects transport data from various data providers and makes them available in a normalised and standardised format. A mobile app connects to the platform and shows the mobility options that are available for the user near a chosen position on the map. Mobility objects on the map are interactive, and can show further information about the chosen object. Each mobility object is graded according to its environmental “friendliness”. The user can choose the types of mobility modes they would like to see, create location favourites, and “auto-jump” to the nearest favourite. As the mobility modes have very different payment schemes, the app will redirect the user to the mobility provider’s own app or webpage to reserve or order each type of mobility option.

Vehicle to Grid and Vehicle to Building technologies:

Vehicle to Grid (V2G) and Vehicle to Building (V2B) technologies allow interaction and transaction of energy from a vehicle to the grid, or from a vehicle to a building. A prototype bi-directional V2G charger has been brought in the +CityxChange project to test it in a market and local energy microgrid setting. 

Recommendations for cities:

  • A multi-stakeholder approach and a variety of core actors onboard is important for the success of car sharing schemes. 
  • Building owners/real estate developers, commercial parking company, and municipality to cover costs for installing, owning, and operating EV charging infrastructure in Trondheim – rather than EV sharing company.
