While it is undisputed that battery electric vehicles (BEV) are considerably more efficient than vehicles with an internal combustion engine during operation, the energy demand for the production of the traction battery currently reduces this advantage. The operational emissions of BEV strongly depend on the underlying energy system, which is currently undergoing a drastic change towards higher shares of renewable energies. This results in a future reduction of the average emission factor of electricity on the one hand, and an increase of the volatility of the hourly emission factor on the other hand. In this paper both of these effects are considered in the assessment of the carbon footprint of BEV by including the changing composition of electricity generators as well as various optimized charging strategies.
