Opis:
The total CO2 emission of electric vehicle depends on a renewable energy share in an energy market of given country. At the moment, this share is significant only in a few European countries (Denmark, Germany, Scandinavian countries) having large number of water, solar and wind power plants. Additionally, France may be considered as a country possessing low-emission electric energy, because around 90% of this energy is generated by a nuclear power plants. In order to compare the greenhouse gas emission from an electric vehicle with combustion powered cars well-to-wheel (WtW) methodology may be applied. The well-to-wheel emission estimates the total CO2 which is required to generate a given power measured on vehicle wheels including generating, transferring and processing losses. The magnitude of WtW varies from 0g/km in the case of a vehicle charged directly by a solar or wind powered charging point to 200 g/km in the case of charging form public grid powered by old coal power plants. For the Polish energy market the share of renewable energy sources is negligible (below 10%), moreover majority of a power plants uses coal to generate electricity. However, according to the EU strategy this share should be doubled until 2020. Additionally, it is considered building of a nuclear power plant, which results in further reduction of CO2 from energetic industry. In this article WtW CO2 emission of electric driven vehicle charged from the public grid was analyzed for Polish conditions at present and various growth scenario as well. Moreover, an actual energy market structure as well as growth perspectives were reviewed.

Opis:
The Well-to-Wheel (WtW) CO2 emission of the electric vehicle (EV) strictly depends on amount of a carbon dioxide (including transmission and conversion losses) required to produce an electric energy used to charge EV batteries. Value of the WtW emission may be lowered by increasing a share of low-pollutant power plants i.e. using renewable energy or nuclear power, however it needs a large financial investments and it is very long process, taking over a dozen years. Even in the case of countries having a large share of low-emission power plants (Germany), a smart grids must be applied in order to optimize a value of WtW CO2 emission. Usually batteries are charged during night, where energy demands are relatively low and at the same time wind turbines supplies majority of electric energy to the grid. Presented idea of the battery charging station described in this article has a local character. It uses photovoltaic panels as a source of "green" electric energy. As a consequence the value of WtW emission for an EV batteries charged in this station equals to 0 g/km. The charging station uses EV battery swap thus the time of staying in the station is shorter in comparison with normal or even fast charging. The battery swapping technology uses replacing of the discharged units mounted in EV by fully charged ones. The batteries are placed in special try, which enables a quick mechanical and electrical connecting and disconnecting. Moreover, batteries stored in the station may be used as an energy storage devices and makes charging process optimization easier; moreover, they can be used as an element of a smart grid system. The article describes model of charging station using both photovoltaic and quick EV battery swap.
