Trusted Green Charging 2.0

About the Project

Electric cars are only as clean as their power supply. That's why we are making the origin of electricity transparent and creating a local price incentive for green charging.

At the Digital Hub Mobility, we are building a prototype that makes the source of power used for charging at semi-public charge points transparent, taking into account on-site generated solar power as well as the CO2-intensity of the grid mix. To incentivize green charging behavior, we developed a dynamic charging tariff that reflects these different power sources. In this way, drivers benefit from cheaper prices when local renewable production is high while charge point operators maximize the use of on-site generated solar power and grid operators benefit from grid-friendly charging behavior.

Challenge

The generation of renewable energies fluctuates depending on location and time. Accordingly, the CO2 intensity of grid electricity fluctuates.

Our Approach

We have developed a dynamic charging tariff based on the hyperlocal CO2 intensity of the charging current. Among other factors, this is based on local and regional consumption and generation data as well as the electricity purchase price.

The Solution

To make the decision to charge green and cheap as easy as possible, we developed an app prototype that suggests the best charging strategy based on the driver's charging needs.

Our Partners

Co-Innovation

This project is part of our citizen mobility format, which aims at companies and startups in the mobility sector. Given the changes in the mobility industry, cross-company and cross-sector partnerships are becoming increasingly important. However, for many of our customers, establishing such partnerships is time-consuming, complex to manage, and difficult to keep on track for success.

Our solutions:

A neutral platform for fast-starting collaborative projects and managing stakeholder interests
Domain-specific expertise and effective project management
Fast, collaborative prototyping to create, test and learn at a rapid pace
Partners include enterprises, startups, academia and cities
