I just read this article and has attracted me much attention because it isn't the classic story about a new chemistry of battery that every week usually appears, it is a breakthrough that will produce just improving materials, packaging and optimization production processes. Here the article in a important german auto blog, in german language: Fortschritte bei Batterietechnik: Ãœberdenkt BMW Projekt fÃ¼r Brennstoffzellen-Auto ? Here the translate with Google Translate: The British magazine Autocar quoted BMW sales and marketing chief Ian Robertson effect that BMW continues working on a PHEV prototype in the conversation but Roberston doubts whether it creates the car according to series production. As one of the reasons he cites the development of the Li-ion batteries. It is striking: If electric mobility until a few months treated with most carmakers like a wicked stepmother, since summer turns the mood. Virtually all premium manufacturers have more or less openly announced all-electric vehicles. Although this has much to do with the Tesla success and how the electric car pioneer stirring up the scene, but even more so with the progress of the Li-ion batteries. There apparently the developers come much faster than originally expected. Had it not been called in the past year in the development departments of Bosch and Continental that you will need to early 2020 to double the capacity of the battery package, it is now probably very close to this goal. Just days ago, Renault-Nissan CEO Carlos Ghosn said in a TV interview that if you were standing in battery technology of a breakthrough and announced that they would double the range to over 400 kilometers for the next generation of all-electric Nissan Leaf , Apparently, these are not "Nissan miracle", but a development on a broad basis. Marcus Fendt, Managing Director, "The Mobility House" (TMH), a leader in providing energy management of electric cars, confirmed to the CAR PRODUCTION: "Li-ion batteries with redoubled energy density end of next year on the market. "meaning: the previous range of compact cars outside the Tesla League climb of 150 to 200 kilometers, are possible today to nearly double. For e-cars come in a range in which the argument of lack of coverage, which inhibits the market success, becoming less important. Important point: the higher energy density can not be achieved, according Fendt about a new technology, but solely through an optimization of the production processes, the use of better materials and a skilful bundling of the battery cells to battery packages. Does the development of the battery Reported actually so rapidly as it is now emerging that could be used for fuel cell technology actually mean quick death. Although the purely electric mobility has then still the problem of load times, against PHEV vehicles but says the billion-dollar development effort and the complete lack of infrastructure. Against this background, BMW now seems actually to send the development of a fuel cell cars again in a Überdenkungs loop.
