Abstract
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. Three cases of cable
connection can be used on alternating current, only the third case – on direct current, and the fourth case – when wirelessly
charging an electric car. Analysis of the principles of use of charging stations showed that they classify portable, wall, and
stationary stations. National standards introduce road signs for electric vehicles, and a European standard establishes harmonized
identifiers for the power supply of electric vehicles. There are some standardized protocols for the interaction of the charging
station and the control server, which are designed to optimize energy resources and energy production systems. A comparison of
existing types of connectors for charging electric vehicles has shown that the standardized interface between the charging station
and the electric vehicle remains one of the most acute problems. Recommendations on approaches to metrological support of
charging stations are formulated. The issue of international and regional standardization of electricity meters of direct current for
use in charging stations remains relevant. International standards are transformed into relevant European standards without
changes. However, in some cases, it is necessary to develop a special European standard, in particular for meters of active
electrical energy of the direct current.
