Tesla doubles battery lifetime or is about to achieve this goal four years ahead of schedule, its chief battery researcher Jeff Dahn announced. He detailed that said cells were currently tested in the lab and not in Tesla’s products yet. The advances result from in-depth research into degradation processes and improved chemistry (we reported). Dahn deals with Nickel Manganese Cobalt Oxide (NMC) battery cells mainly, which Tesla puts into its Powerwall and Powerpack. Still, the scientist said they had also started to look into the vehicles’ batteries made from Nickel Cobalt Aluminum Oxide (NCA).
Pure power: Researchers from the University of Antwerp and KU Leuven have developed a process that purifies air and generates power at the same time. The device needs nothing but light to cleanse air in one chamber and produce hydrogen in the other. The team now seeks to upscale its membrane from only a few square centimetres to industrial application eventually.
600 V converter: The Fraunhofer Institute IAF has developed a half-bridge circuit for the 600 volt class in which all the electronic components are monolithically integrated on one chip. The GaN chip enables compact designs at improved electronic properties.
REx for buses: TM4 and Cummins joined their efforts to build a plug-in hybrid system for buses that reduces fuel by 50 percent compared to conventional hybrid buses. Their drive is more of a range-extended electric motor with a 111 kWh onboard Li-ion battery. It can be used in 6 – 18 metre vehicles.
