Sind Probleme beim Laden von Elektroautos nichts mehr als ein Mythos? Daimler sagt ja.
As with many new technologies, electromobility needs to prove itself in the face of a flood of prejudices. Among these are numerous false, yet frequently propagated assertions. One examples concerns rapid charging, which allows electric vehicles to achieve a range similar to that of those with a combustion engine. The possibility to charge the battery within a short period of time is far too complicated and prone to problems, according to these sceptical, self-proclaimed "experts". Furthermore, the tech-sceptics add, regular charging leads the batteries to implode. The necessary infrastructure is also not given, they say.Complicated and problematic? Insufficient infrastructure? Imploding batteries? Jürgen Schenk, Head of Electric Drive Integration at Daimler AG, smiles. "There's nothing complicated about rapid charging. Our electric vehicles will all be equipped with a plug on the side wall which permits charging with both alternating and DC voltage." This is the so-called CCS connector (Combined Charging System), which is standard in Europe. For rapid charging, using alternating voltage means charging can theoretically be carried out with 43 kilowatts. "In practical situations," explains Mr Schenk, "the chargers currently offer between 7 and 22 kilowatts. In order to be able to charge the battery, the vehicle must be appropriately equipped with a system which transforms alternating voltage into DC voltage. The majority of vehicles are currently equipped with a system suitable for eleven kilowatts. This way, a battery can be charged sufficiently for a range of 500 kilometres in approximately seven to eight hours."
