Good for the city – reliable, innovative, efficient and social

Disposal and recycling, clean streets and safe traffic are the tasks of BSR’s 5,300 employees. Quality service, low fees, ecological and social responsibility are part of the strategy of our innovative and sustainable company.

Short description of the project contribution

Electromobility and battery storage – load-controlled charging of a battery-powered passenger car fleet

As a result of the energy transition and the ever growing volatile share in electricity generation – i.e. from renewable energy sources – the relevance of storage systems and flexible loads on the consumer end is also increasing. BSR also supports the aim of the city state of Berlin to be ‘climate neutral’ by 2050 and promotes this through the expansion of electromobility, among other things. The BSR fleet has a total of 1,600 vehicles; its share of electricity-powered vehicles is gradually increasing. Thanks to the operating conditions, it can be used as a demonstration of flexible loads in electromobility.

In order to tap the far-reaching potential of electromobility and integrate vehicle charging as a flexible load in the electricity market, BSR will first create an internally networked charging infrastructure at several of its own locations. For the further use of the flexible load and to demonstrate smart charging management, additional networking on an ICT platform with external players is planned, linking producers and users, the electricity grid and markets. The results of this project are captured in a scalable electromobility roadmap that is scalable and can be applied to other fleet operators.

The use of electric vehicles as flexible load harbours potentials for all electricity market participants: a smart charging management ensures that the load availability can be flexibly adjusted to the requirements of the system operator on the one hand and that on the other hand, the necessary charging time of the vehicles is maintained for the operator and that flexible charging becomes attractive thanks to such incentives as favourable prices. A networked charging infrastructure enables the operator to act independently of publicly accessible offers and shift the required loading times of the vehicles with up to eight hours to periods during which the service vehicles are generally at a standstill.

The first milestone will be the completion of the charging infrastructure at the BSR sites in early/mid 2018. By networking this hardware, the BSR lays the foundation to demonstrate the controlled charging of its electromobility fleet. The assessment of the framework conditions, restrictions and prioritisations will result in the creation of a roadmap for operational electromobility.
