【 摘 要 】

The article presents the results of research regarding energy efficiency on the electric energy conversion chain: electric socket-charging device-electric vehicle machine depending on the amount of energy taken from the battery, which in a simple relation results from the distance travelled by the vehicle. The tests were conducted on a Melex-type light-duty vehicle. Measurements were made for five test routes with lengths from the range of 5.4 km-up to 43.4 km. The obtained results allowed to indicate the optimal distance between successive charging processes due to the obtained efficiency of energy conversion in the analysed chain. The specific energy consumption of the vehicle in terms of batteries-to-wheel (tank-to-wheel) and electric socket-to-wheel was estimated. Moreover, the results of estimation of the equivalent CO2 emission resulting from the use of an electric vehicle which batteries are loaded from the power grid for several example European countries with a significant differentiation of electricity production methods are presented.
