Overheating is one of the main reasons that accelerates the rate of battery discharge in electric vehicles and leads to the deterioration of its performance over time. Rapid charging of the battery is not beneficial for its longevity, as high currents increase the temperature and can irreversibly damage the internal structure of the battery. At optimal temperatures, the availability of discharge power, charge reception during regenerative braking and battery health are at the best level.

The article analyzes and compares charging stations for electric vehicles and their components. The analysis of charging modes of electric vehicles showed that four internationally standardized modes are used, three of which use alternating current with single-phase and three-phase switching and only one – direct current. When charging on direct current, the fastest charging is provided. There are four standardized cases of connecting charging stations to electric vehicles.

Tendencies of sustainable development of transport, the use of alternative energy sources, and requirements to the reduction of the carbon footprint on all stages of life cycle on all levels of road transport have led to the increase of the share of the electric car both at the first registration and used vehicles. The appearance of a large amount of used modern electric cars on the market caused the necessity to develop the procedures of provision their technical operation both by requirements of rational use and provision of traffic safety.
