Intelligent Load Management for e-vehicles

Uncoordinated charging of electric vehicles can lead to load peaks in electricity consumption and thus to high costs – especially for companies and fleet carriers. So the solution here is Intelligent load management.

A recently published short study, issued in cooperation with ÖKOTEC, shows how intelligent load management can be used as a further brick of energy transition for industry.

Intelligent load management enables electricity to be obtained only if the sufficient capacity in the power grid exists. In addition, renewable energy can be used more efficiently and thus actively contribute to environmental and climate protection.

The share of electric mobility is increasing continuously.

Around 309,100 electric cars are currently registered in Germany. Compared to the previous year, the number has more than doubled (Statista). The federal government is seeking seven to ten million registered electric vehicles in Germany by 2030. The aim is to reduce the CO2  emissions in the transport sector by 40% – 42%.

The governmental electromobile funding programme of the German Federal Ministry for Economic Affairs, Energy and Technology is currently boosting 30 research and development projects aimed at building of intelligent and sustainable charging infrastructure.

Load management reduces fees and procurement costs. 

With some 5,600 employees,  the Berliner Stadtreinigung (BSR) provides for urban waste disposal and recycling, clean streets, and traffic safety. The company’s innovation and sustainability strategy focuses on efficient operations, low fees, and ecological and social responsibility. BSR was in need of a charging infrastructure solution for its electric vehicle fleet, which is currently under expansion. In addition to taking the requirements of the energy transition into account, this solution would need to be future-oriented, cost-optimized, and consider all usage requirements of the EV-fleet.

In Cooperation with ÖKOTEC a flexibility concept for the software-based automated charging of the e-vehicle fleet was developed. The delivered solution was an optimized charging process. Vehicle charging is emphasized when there is surplus of renewable electricity in the grid, and the costs of electricity generation are minimal. The solution is based on EnEffCo®, the energy efficiency monitoring and optimization software.

EnEffCo® allows to charge electric vehicles whenever a lot of renewable electricity is available. This reduces procurement costs while also contributing to the success of the energy transition.

Thanks to the intelligent charging control, the Berliner Stadtreinigung (BSR) was able to save 16% per MWh, avoid peaks and reduce costs. 

More efficient use of renewable electricity creation capacities. 

With intelligently controlled charging processes, renewable capacities can be used more efficiently, reducing the need for or the use of backup power stations and storage facilities. Electricity sourced from renewable energy can be used to a greater extent by adjusting the time of electricity needed.  Renewable energy is an important contributor to environmental and climate protection. The share of renewable energy in Germany is to be increased from currently 33%  to around 80% of gross electricity creation by 2050 (Renewable Energy Act).

Study reveals concepts of implementation of Intelligent Load Management.

The short study “Controlled charging of electric vehicles via price incentives” presents selected concepts for the implementation of price-controlled Load Management. The presented funding projects serve as a base for economic and technical use and   implementation as well as for further development. The challenges of price-controlled Load Management are shown in these concepts. This short study was developed as part of the accompanying research on the funding programme of e-mobility.
