Abstrac: Electrical transport is developed very dynamic for last several years. The comfort and reliability are important as much as energy efficiency in the modern transport vehicles. Energy efficiency is determined by various factors which have to be used complex.

The first electric bus in the Europe was put into service by "Electrical transport Sofia" JSC. Electrical ac motors which are installed on the electrical bus are power supplied by supercapacitors. This s the construction of charging stations (currently two) in Sofia, which are powered supply by traction network.

The main results of the study of energy efficiency of the electric bus operated in Sofia are present in the current paper. Measurements were conducted in the final charging stations with precise measuring equipment. A comparative analysis of main energy indicators with similar types electric vehicles. On this basis, formulated concrete conclusions and recommendations.
