The Photovoltaic system makes use of two types of solar panels- one 1400 W, based on PV mono crystals cells with a dynamic following unit, and a second stationary 480 W, with PV amorphous silicon thin-film cells. The wind generator has a 1500 W turbine. There is a powerful 48 V/1000 A/h battery, which allows for a high peak of energy charge, if quick charging is necessary.An autonomous inverter with power of 5 kW supplies energy with the required parameters for charging of the vehicles.
An automatic unit keeps a steady temperature, which guarantees permanent capacity and a long-life operating mode of the battery. The capacity of the battery depends on the operating mode of the station. Additionally, in the station there is a 500 L filter water tank for cleaning the PV panels. It is filled with rain water.
The charging station has a very compact design and there are no difficulties for transportation and location in different areas. It will be built and tested in an operating mode in Stara Zagora.
For this purpose the company "Belchev Motors" has bought one parking lot in the center of Stara Zagora, where the first recharging point in Bulgaria will be positioned.
