This article describes the features of the use of electric and hybrid drive in transport vehicles. Considers the limitations of using all-electric vehicles. The necessity of developing a hybrid drive for heavy-duty vehicles is substantiated. The basic formulas for calculating the power of an electric drive hybrid vehicle are resented. A comparison is given of the results of the calculation of the main dynamic characteristics of the transport vehicle with various types of power unit. To which include: acceleration time, acceleration path and the average speed of movement. In conclusion, the most efficient type of drive is determined.
