Purpose. The further introduction of electric transport is largely constrained by the insufficient energy capacity of existing energy storage devices. One of the possible replacements for the chemical accumulator is the flywheel energy storage, which has important advantages. This advantage is its potentially huge storage capacity. One of the disadvantages of flywheel drives is the presence of a gyroscopic moment, which leads to a deterioration in vehicle handling. Methodology. The authors of the work in their development of the flywheel drive have eliminated a number of shortcomings, but to use the drive, it is necessary to develop an operation algorithm and a mathematical model. A mathematical model of electrical and mechanical processes in the author’s electromechanical energy storage system is presented. It is shown that the charging and discharging currents of a storage device change exponentially with time, which should be taken into account when developing a specific implementation of drivers for storage motors. The algorithm of operation of the proposed electromechanical energy storage system in the modes of energy storage and energy withdrawal has been developed. Results. The verbal and graphical form of the algorithm is presented. It is noted that in the presence of an electromechanical transmission on a vehicle, the advantages of such a drive increase even more, which prompted the authors of this work to develop a new electromechanical transmission, which the authors plan to combine in the future with the developed drive based on one vehicle. Originality. In the direction of further increasing the efficiency of using the proposed storage device, as well as, incidentally, of their other types, it is also planned to use the electromechanical system for transmitting electricity to the vehicle, developed by the authors. Practical value. In the future, it is also planned to expand and clarify the algorithm of the drive, in order to take into account the types of charger, energy source, the presence of batteries on board the car, depending on the characteristics of the vehicle, road conditions, driver qualities, weather conditions, etc. (at the limit, go to an intelligent control system). It is planned to create a more detailed model of the drive. Figures 4, references 21.
