During this time, an electric-powered city buses are still using very large batteries to store electrical power. With the enormous size of the battery, forced number of passenger seats reduced and battery charging takes a long time.
A consortium of German city bus creates electricity that the battery can be recharged very quickly. Thus, the city bus battery can be made smaller so as to restore space for the passenger seat. European consortium works EDDA Bus that allows the driver to use a number of bus stops on the way to charge the battery. How to use the system created by M & P partner.
The bus stops at no instructions are seen and heard so that battery charging devices can be attached to the battery charging contacts on the roof of the city buses. The design of the Fraunhofer Institute for Transportation and Infrastructure Systems (Fraunhofer IVI) together with Schunk Bahn- und Industrietechnik contact include positive and negative poles on each side of the bus, equipped with a grounding system for safety.
Not only that, the system contacts can be made in the form of a slide rail allowing a little space while attaching the charging contacts.
The battery is made by Hoppecke Advanced Battery Technology by using electronics developed by Vossloh Kiepe. Fully charging the battery only takes 6.5 minutes.
EDDA bus system began in November last tested in the city of Dresden and passed. The second phase of testing was conducted in February by a longer route, which is 20 kilometers. However, there has been no word on their use on public roads.
In the official website of Fraunhofer, explained that the Fraunhofer IVI in Dresden has four departments and two research groups together. The research group consists of 80 researchers in collaboration with the Technical University Dresden and the Technical University of Freiberg.
