Companies in the Hamburg business community were approached to trial the use of electric vehicles in their fleets. Charging points were installed on the sites of the companies concerned and locations for further charging points along the public road network also identified.
In order to facilitate non-discriminatory access to the charging infrastructure for third-party electricity providers, the consortium created a one-off nationwide legally compliant contractual model for third-party access, which also ensured the use of green electricity. It was defined as a binding criterion in the project that the electricity must be sourced from renewable energy, which was agreed and coordinated with the relevant city authority.
In order to facilitate increased use of green electricity on the power grid side as well and to reduce generation peaks, the consortium ran, as an example, some initial trials of charging vehicles on company sites where the charging process was controlled on the basis of the load on the grid.
Integrating all public and private charging points into one central computer system enabled complete monitoring of the charging infrastructure in respect of any functional deficiencies. It also made it possible to keep a check on consumption levels and charging times in order to explore future development of this innovative charging method and its potential for easing the load on the grid.
