Wolfram Walter of German energy storage maker ASD Sonnenspeicher – who converted his own sports car into a solar-powered EV – believes the established practise of connecting battery cells in series is holding back the potential of e-mobility.

The acquisition of a “next generation” battery start-up by Bosch could be a milestone for the e-mobility sector, but represents a risk for the German engineering giant, according to one analyst.

German mechanical engineering company Manz has supplied a lithium-ion battery production line to a research centre for the commercial production of the batteries, initially for the e-mobility sector, at the Center for Solar Energy and Hydrogen Research Baden-Wuerttemberg (ZSW) in Ulm.
