Description

The technical solution refers to technical means of electric charging (recharging) of mobile electric transport units, such as electric buses, hybrid trolleybuses, electric cars (electric cars), hybrid transport using battery energy, electric moped, electric bicycles, electric motorcycles and others.

To charge the batteries of electric vehicles, alternating (single or three-phase) and direct current are used / http://www.antonov.svoi.into/change.php=sthash.qy8qJIzp.dpbs/. To use the AC network, it must be rectified and the voltage reduced to the voltage of the on-board network of an electric vehicle. Due to the bulkiness and overheating in operation, the power of such chargers significantly increases the charging time. Charging with powerful direct current allows batteries to be charged much faster, but requires the creation of a special infrastructure for charging stations.

Charging standards for electric vehicles and plug-in hybrids are recommended by the International Electrotechnical Commission (IEC). The main standard is IES 62196, which determines the types of connectors used (sockets and plugs) and charging modes. Charges are divided into AC and DC charging. In this case, the traction battery in a DC electric vehicle, therefore, to use the AC charging station, an on-board electric vehicle charger is used, which converts the alternating current of the charging station into a constant current, which charges the traction battery. The charging speed of an electric vehicle is determined by the power of the on-board charger.

AC stations are standard charging stations, and DC stations are express charging stations or fast charging stations.

There is a known system of an electric charging infrastructure network containing an electric energy storage device in the form of a charging station and a mobile electric vehicle charged with electricity, connected by a connection device, while the charging station includes a power source for supplying charging power to an electric vehicle battery, a current measuring device for monitoring the power supplied a power supply and a control device (CPU) for incoming / outgoing information for generating, comparing and identifying current changes in current, including a processor and software (see US patent No. 2013328525, IPC H02J 7/00, publ. 12.12.2013) ...

The known system for its construction and operation requires large material costs, takes up a lot of space, requires certification and is used mainly in urban areas.

Arrangement of the known system under operating conditions on the road transport infrastructure is not economically feasible.

In this case, communication with the control center can be carried out via a wired or wireless) mobile communication channel.

For the transmission of control signals and data transmission programs, each charging station either has a controller and a switching module, which are in communication connection with a database operating according to the master-slave principle. As a data transmission line for the database, the power supply line of the power system is used, in which an intermediate control and switching module is located at the installation site of the charging station (see patent WO No. 2012041902. IPC B60L 11/1816; B60L 11/1824; publ. 05.04.2012).

The charging control signal is configured to adjusting the parameter used for the consumption of electrical energy from the electric vehicle charging station and adjusting the charge transfer based on the adjusted parameter (see US patent No. 2016364776. IPC B60L 11/18; G06Q 30/02; H04L 29/08; H04W 4/02 , publ. 12/15/2016).
