The market for electric vehicles (EV) is preparing for rapid growth in the coming years. All major car manufacturers have announced to launch an electric vehicle. The Dutch market is expected to expand to 15,000-20,000 EVs in 2013, and 1,000,000 EVs in 2025. The ambition of the Dutch government is to have 200,000 electric vehicles on the road by 2020, and a continued growth to a mature market of 1 million vehicles by 2025. For scaling up the number of electric vehicles, a charging infrastructure with 500 fast charging points is essential.

However, anxiety regarding range and finding charging stations can be a major concern for EV drivers; this range anxiety can be alleviated with the availability of fast charging stations at central locations, where a car gets fully charged within 30 minutes. The availability of fast charging stations plays a major role in the acceptance by a broad group of consumers.

An important technical challenge related to electric vehicles is the effect of charging on the classic energy grid. Moreover, the classic energy grid is not suited for fast charging of EVs, as this is accompanied by very high peaks in energy demand. Innovative solutions should be developed to overcome this problem.

MisterGreen aims at developing an important next step for electric transportation: sustainable fast charging stations next to Dutch highway gas stations, where electric cars get fully charged in 30 minutes using solar energy. MisterGreen aims at developing a smart-grid solution – the energy needed for fast-charging is available via energy storage buffer batteries. There will be no peak energy demands on the classic energy grid as these batteries serve as energy buffer. The storage buffer batteries are charged using solar panels. A lack of available solar power can be supplemented by power from the grid.

Mistergreen will realize and manage a nationwide network of fast charging stations at the best locations in the Netherlands. Concessions for twenty highway locations throughout the Netherlands have been obtained until 2027. The fast charging stations will be realized next to gas stations along the highway in the Netherlands.

Intergrated solar panels for onsite electricity generation will charge the batteries of the charging station. Both the battery storage and grid power provide for fast charging the EV. The battery storage pack will serve as a load-balancing power source and has smart grid functionalities.

At these highway fast charging stations, drivers can fill up their car with sustainable solar energy in less than 30 minutes.
