When the CO2 emission in the production of the batteries and the German total electricity production in charged, charge an electric car, the climate 11 to 28 percent more than a diesel car, it sounds in the study. That was published today. the
Batteries and electricity
For the extraction and processing of lithium, cobalt and manganese for the batteries is a lot of energy is needed. A battery for a Tesla Model 3 for the climate with the 11 to 15 tonnes of CO2. In a ten-year life span for the battery and an average distance of 15,000 kilometres per year, means that all 73 to 98 grams of CO2 per kilometre.
It is then the CO2-emissions for the electricity consumed. In reality punch the Tesla then between 156 and 181 grams of CO2 per kilometre. That is clearly more than a comparable diesel car, for example, the German brand Mercedes.Unrealistic threshold
the European politics of electric cars as zero-emissievoertuigen considers, the researchers also criticized. From 2030, the prescribed CO2 limit of 59 grams per km would correspond to a consumption of 2.2 litres of diesel or 2.6 l petrol per 100 kilometres, and is, according to the scientists “unrealistic".
By which the new limit values should car manufacturers now a large part of their cars with electric drive to sell. "For the climate, it would be better, however, with methane (natural gas) powered internal combustion engines. The CO2-emissions is still a third lower than that of a diesel engine", according to the scientists.
