Batteries in a buggy

ebuggy envisions a network of stations for pickup and dropoff of the battery-filled trailers.

Why permanently weigh down an electric car with an outsized, excessively heavy battery when EV drivers can hitch up a small trailer full of batteries for the needed driving distance and then unhitch the unit when no longer needed? Indeed, says Stuttgart company ebuggy GmhH, which has developed a prototype battery trailer and is working to develop a network of pickup/dropoff stations to allow unlimited range for various EVs. The beauty of the vision, says ebuggy, is that EV makers can design their cars with smaller, less expensive battery packs and thus charge customers less. In a Sept. 19 press release announcing ebuggy, the company noted that the prototype trailer was constructed with the support of the Germany Ministry of Economics and Technology and several project partners including the Fraunhofer Institut IPA and Stuttgart University.
