Project for living apartments
In the 21st century, electric vehicles have gained wide popularity due to the new opportunities that open up for their owners. On the one hand, this is the use of energy without emissions into the atmosphere, on the other hand, government support in the form of subsidies. We should expect an increase in the popularity of electric vehicles among urban residents.
The city's infrastructure is used to charge cars, but the most convenient charging method is to charge an electric car at home when it is not in use, such as at night.
At the same time, the living apartments built in previous years are not always adapted for the use of electric transport.
Our solution makes it possible to organize an electric vehicle charging point in apartment associations where this was not provided in the original project.
The charging system could be organized in the following way.
One or more parking spaces are allocated in the parking lot of the association for charging electric vehicles. These places can be used for charging by car owners in turn. Each owner can take any free space for charging. Thus, with a small number of charging stations, a fairly large number of electric vehicles can be serviced.
The rest of the parking spaces are normal. They can be parked in ordinary cars and electric cars that do not need charging.
The equipment belongs to the common property of the house. A charging point may consist of one or more chargers. The number of chargers is selected based on how many electric vehicles will be charged at the same time.
Electric vehicle owners charge their cars and identify themselves with RFID tags. Most often, a keychain or a plastic card is used. Smartphones, watches, and some other devices can also be used as tags.
You can use existing tags or purchase new ones.
Only users whose tags are registered in the system will be able to use the charging of the apartment association. Outsiders will not be able to use the charger. The number of registered users can be changed at any time by software.
Periodically (once a month) data in an EXCEL file will be sent to the Board of the partnership and it will be seen how much energy each user consumed. This data may be included by the partnership in the utility bills of the respective apartments.
There is another way to organize charging. Charging stations are installed in parking spaces. The owners of electric vehicles each time identify themselves, the data is transferred to the board and every month the payment for the consumed electricity is added to the bill of a certain apartment.
The price of electricity for charging can be set arbitrarily by the partnership, usually it is always slightly higher than the market price of electricity. Thus, the partnership receives additional income. You can make a fixed price or link to the exchange price, for example, exchange price + 0.05 euros.
Charging electricity is accounted for separately from other energy. Under certain conditions, discounts can be obtained from the energy supply organization.
Electricity is metered using meters that comply with the MID Directive of the European Union (The Measuring Instruments Directive 2014/32/EU).
The charging point is connected to a special charging board, which is located in the technical room and is the common property of the house.
The charging shield is connected to the main shield of the house. In the charging shield, electricity is regulated, which is sent for charging. If at some point, for example, in the evening, the house consumes a lot of energy, then little or no energy is sent to charge electric vehicles. And if the house has unused energy within the limits set by the electric utility, then a lot of energy can go to charge. The maximum is set in the charging shield settings.
This dynamic load balancing avoids overloads in the power system at home. Only the amount of energy that is not used by the house from the set limit will be sent for charging.
The charger also has dynamic load management. This does not allow exceeding the set limit of energy that is directed to charging, depending on the number of simultaneously charged cars. For example, if a limit of 60 kW is set, then the electricity will be distributed as follows:
1 car - 22 kW
2 cars - 44 kW
3 cars - 60 kW (20 kW for each car, 20 * 3 = 60)
4 cars - 60 kW (15 kW for each car, 15 * 4 = 60)
5 cars - 60 kW (12 kW for each machine, 12 * 5 = 60)
Etc.
The most appropriate solution seems to be the use of charging stations Teltocharge 22kW with cable 5m. This version has a built-in cable. It is convenient, the driver does not need to get his cable out of the trunk every time.
The station is connected to a three-phase network. All types of vehicles equipped with a Type 2 connector (approved by the European standard IEC 62196) can be charged from it.
The equipment complies with European electrical safety standards for use by unqualified people.
Chargers are sufficiently protected from external influences. They can be placed in a closed (underground) parking lot or outdoors.
Detailed technical data are in a separate file.
Charging stations are set up via an application connected via Bluetooth.
Optional: data on the charging process, on the status of charging stations can be transferred to the server.
If your association is interested to install charging system, please contact us to get a free consultation.
