Carsharing was appeared at the beginning of the last century with the idea of offering cars for rent. The subsequent development of rental allowed carsharing to take shape as an independent direction in 1971 and in 1991 the European car sharing Association was established. Further computerization made this service more accessible. However, in 1992 the European Union introduced the Euro-1 environmental standard. Further tightening of environmental standards has forced firms to take a fresh look at the provision of carsharing services. As a result, owners were turned to cars with hybrid, hydrogen and electric motors. Due to significant progress in increasing battery capacity the electric vehicles are the most promising for this field of activity. However, the issues of placing charging stations in places where electric vehicles are used intensively in order to provide quick access and reduce waiting times in the queue are still not fully worked out.

The article deals with the formation of the cluster core and its environment with the clarification of the organizational structure. Much attention is paid to the necessity and sufficiency of including organizations in the cluster at the time of its formation and initial stage of operation. The authors suggest to use a ranking method based on the significance of the cluster’s areas of work as well as the organizations that belong to each of them. At the same time, the cluster’s work areas are related to the its missions in the destination: industrial; innovative; satisfying the requirements inside the cluster; satisfying the requirements outside the cluster; social; territory development; cluster development. Within each of the directions the minimum number of organizations sufficient for the effective operation of the cluster was determined. Then the cluster organizations were ranked according to the allocated missions. Based on the ranking organizations of primary importance at the initial stage of the cluster are identified: organizations that provide financial services, supply machinery, equipment, production lines and knowledge as well as bulk buyers. The cluster has a “zone of necessary organizations” for starting the cluster as well as a “zone of efficiency increasing” that can be expanded and replenished as necessary.
