Vasile Cristea, Siemens Romania: “We offer end-to-end solutions for e-mobility, from charging stations to their integration in the grid”
“We need to differentiate between the types of charging stations for e-cars and the type of applications. For office buildings, hotels, supermarkets, malls, are suitable slow charging stations, up to 22 kW. For gas stations, on national or international corridors or on highways, are recommended ultra-fast charging stations.” Vasile Cristea, Head of Business Unit Distribution Systems,Siemens Romania, said during e-Mobility Forum 2021 organized by The Diplomat-Bucharest.
The price of electric cars is not affordable for a majority of the population. There are also those challenges related to range anxiety even for those people who can afford to buy an electric car. There is a high dependency between the number of electric cars on the roads and the number of charging stations that can serve these vehicles.
In Romania, there is a financing program that supports the purchase of electric vehicles. In terms of charging infrastructure, there is a need for complementary support from local authorities for electrical chargers and also for electrical grid modernization required for chargers integration.
We need to differentiate between the types of charging stations for electric cars and the type of applications. For office buildings, hotels, supermarkets, malls, slow charging stations up to 22 kW can be installed. These chargers are usually connected in low voltage networks, and their impact on the network is not significant.
When we talk about fast and ultra-fast charging stations, with over 50 kW, these solutions find their applicability in gas stations, on national or international corridors or on highways. Electric car drivers want to spend as little time as possible to charge and have a stationary time for charging comparable to drivers of cars with internal combustion engines. In this case, the projects are more complex and we can provide consulting for the integration of stations in the electricity grid.
