The system of urban charging for electric vehicles is at the industrial tests process in Novosibirsk.
At the end of 2019, NSTU NETI and AO Electroagregat won a grant from the Government of the Novosibirsk Oblast for the development of dual-system charging stations for electric vehicles. Currently, scientists of NSTU NETI have completed research work on the grant. They have developed a charging station for electric vehicles. The unique technical solution can be connected to urban electric transport substations. "We have developed and tested a prototype electric charging station. In January 2021, the necessary equipment was taken to the Electroagregat plant", commented Aleksandr Shtang, coordinator and one of the project developers, Associate Professor at the Department of Electrical Engineering Systems, NSTU NETI.
Testing of a fast electric charging station with an installed capacity of 25 kW operating in accordance with the requirements of the CHAdeMO standard, was carried out on the basis of the Nissan Leaf, the most common Japanese electric car in Russia. Quick charge mode allows charging Nissan Leaf to 80% of the battery charge in 30 minutes. The developers plan to significantly increase the capacity of the electric charging station.
The advantage of the project is encompassing two systems: the station can operate both from an alternating current source with a voltage of 380 V, and from a direct current power supply system of urban electric transport with a voltage of 600 V.
"Charging stations can be integrated into the existing electric transport system. In fact, electric capacity in cities is limited, and the proposed charging station can load the existing traction substations, which currently have a significant power reserve and will not require the construction of additional infrastructure and an increase in existing capacity. Now in Novosibirsk there is a distributed network of more than 30 traction substations, and each of them can be connected to several charging stations. Similar traction substations are available in all major cities of Russia, which means that the NSTU NETI development can be used to quickly deploy charging station systems in large cities and solve this problem.
At present, there is a steady trend towards a significant increase in the purchase of electric vehicles in Russia, an avalanche growth is expected in 3-5 years, which means that today it is necessary to make efforts to deploy a combined system of charging stations", said A. Shtang.
Aleksandr Derishev, CTO, AO Electroagregat confirmed that the company is starting to test the NSTU NETI development. February will see debugging, the next stage of a prototype charging station testing. The development is to be available for purchase this summer or autumn. The implementation will depend on the readiness of the city and the demand. According to the experts of Elektroagregat, Novosibirsk has this demand and it will continue to grow along with the number of electric vehicles.
