Conversion of traditional cars with internal combustion engines into electric vehicles (EV) is quite relevant for companies that deliver or transport mail, small-sized and lightweight cargo, food delivery from restaurants, for courier services, etc. EVs have significant advantages, namely, they do not require frequent maintenance, are much more reliable than traditional cars with internal combustion engines, more economical and environmentally friendly. Therefore, studies were carried out on the rationality of converting a car from an internal combustion engine to an EV with the calculation of the payback period of the converted car. Considered the main components of the EV configuration. The calculation of the power of the electric motor for the selected electric vehicle has been carried out. The calculation of the economic indicators of the conversion of the ZAZ Lanos-pickup car into EV has been carried out. The calculation results show that in the 3rd year of operation of the converted vehicle, a payback of the costs incurred will be obtained. The graphical dependence of the traction motor power on the EV speed is built. Calculations are carried out and the dependence of the traction motor power on the road slope when the EV is moving at a certain speed is built. Re-equipment of cars with internal combustion engines into EVs is expedient and cost-effective to implement for companies engaged in a variety of services for the delivery of goods within the city. But here one should take into account the fact that charging infrastructure should be developed within the city or night charging should be provided at the parking place.
