Project goals

The aim of the ComfficientShare project is to develop, implement, and test shared charging and electrified car-sharing solutions at the district level. These solutions should be designed to guarantee the users comfort and reliability at a low cost. At the same time, the operation of charging points and vehicles should be made economically attractive for the operator by increasing efficiency and capacity utilization. The project focuses on the complete electrification of a test site by introducing electric vehicles and charging points into an urban residential district. The charging points and vehicles are used exclusively by local residents and are specifically integrated into the energy system of the site so that the installed connected load can be kept low. The project aims to derive recommendations for action and findings that help to reduce the number of vehicles in urban living quarters and to electrify them, to reduce the investment required for the expansion of the charging infrastructure, Derive recommendations for action and design for new housing projects and create economic business models for charging infrastructure and car sharing operators. Findings from the project will be used by the consortium partners as a basis for the development of the new vehicle, mobility, and charging infrastructure concepts. In addition, ElectromobilityProvider (EMP), fleet operator, charge-point operator (CPO), housing associations, and manufacturers of charging hardware can gain insights into the design and operation of economic business models in the field of site electrification.

Contribution of the project to the implementation of the M Cube overall strategy

The results of the project contribute to the development of a district-level electrification solution that is functionally and economically beneficial for users, housing companies and operators. The resulting simplification for shifting to electric vehicles makes an implicit contribution to improving air quality in metropolitan regions. Project findings on effective sharing also contribute to a reduction in the number of parking spaces required and a lower number of vehicle kilometers, which improves the quality of space and air.

Approach

Preparation
Analysis of possible real-lab sites with regard to inhabitant structure and energetic boundary conditions with subsequent selection of the most suitable site for further experimental implementation.

Experimental phases
The test implementation is divided into three phases:

• Phase 1: Analysis of the previous mobility behavior of the study participants using an OBD logger and smartphone app.
• Phase 2: Five households are each provided with an electric vehicle for their sole use instead of their previous vehicle with an internal combustion engine.
• Phase 3: Implementation of a car sharing model at the residential location. The five electric vehicles are now shared by several households.

Simulation
Transfer of the determined test data to an overall model of Munich in order to investigate influences of the concept on the overall mobility and the effects on the power grid in the city.
