In the second episode of our Advent special, Dr. Veronika Wright (Electrified Veronika) and Prof. Jürgen Janek (Justus Liebig University Giessen) answer the following questions:
-
Many people think it can't be more sustainable to give up my combustion engine now and buy a new electric car. I'd better drive the combustion engine to the end and then switch?
-
How does the sustainability of an old combustion engine compare with a new BEV? Are there any figures here? (Tobias Ender)
-
Dr. Wright, you converted a Jeep Wrangler: What were the biggest challenges? Now that it's finished - would you do anything differently in the future?
-
Is a widespread conversion of combustion engines using standardized conversion kits conceivable and economically/ecologically sensible? (Robert Laumen)
-
Power electronics: What are the main tasks of the inverter?
-
Does preconditioning (heating) the battery for fast charging require more energy overall than not doing so (and then charging more slowly at the charging point)? Does this effect cancel itself out? Which of these charging processes is more energy efficient?
-
We have been preaching here for years that frequent fast charging stresses the battery and damages it. A new study from the USA now confirms that Tesla energy storage systems are considerably more resilient than previously thought. Has so much progress been made in batteries and power electronics that fast charging no longer harms the battery?
