Marelli to manufacture e-drives in Cologne, Germany
The automotive supplier Marelli is planning a production facility for electric vehicle drives in Cologne, Germany that will go into operation in the first half of 2021. The company based in Japan has not yet provided technical data on the drives built there.

Nanowire system: UC Irvine researchers have developed a nanowire-based hybrid energy storage system with reported reversible cycle stability for up to 200,000 cycles and a 94-96 percent average Coulombic efficiency. The battery/capacitor could theoretically be recharged hundreds of thousands of times. The project is funded by Nanostructures for Electrical Energy Storage.
Venturi tech: Formula E team Venturi will be working with Japan’s Rohm Semiconductor to introduce silicon carbide technology at the start of season three. A Venturi Fomula E show car will be displayed by Rohm at this week’s Hanover trade fair, alongside examples of the relevant SiC technology.
Formula E partnership: Italian technology company Magneti Marelli teamed up with Mahindra for the FIA Formula E Championship’s third season. Mahindra’s M3Electro will feature Magneti Marelli motors and branding. The motor weighs just over 23 kg, and the Italian company may work with at least one more Formula E team next season.
Tesla Easter egg: Entering the access code “performance” into a Model S or X, lets drivers test out other model versions. Teslarati downgraded and test drove their P90D at a 90D and 70 level, toggling back and forth between energy consumption values for the different modes. However, they suspect the egg is only for fun and does not provide a real service.

Efficient separation: Researchers from Swiss Paul Scherrer Institut (PSI) have developed a coating that helps separating gases and water in fuel cells to make them more efficient. The team created “run-off channels” within the porous material, thus ensuring the gases can flow more quickly, making fuel cells more stable and powerful.
Motor race: Italian Magneti Marelli has developed an electric motor strong enough for the Formula E. The ‘MGU-FE’ has a peak power output of 300 kW and a torque of 200 Nm, while it is said to weigh less than 23 kg. Teams might get to use it from season 3 of the electric racing series.
Scraps to caps: Researchers at Oak Ridge National Laboratory and Drexel University are upcycling scrap tires to produce flexible polymer carbon composite films to be used as electrodes for supercapacitors. After pre-treatment and processing, the resulting composite paper is highly flexible, conductive, and has a high capacitance.
ZF EV powered by Akasol: The Advanced Urban Vehicle that ZF presented at the IAA utilises a Li-ion traction battery made by Akasol. Eight modules are divided into three system units (2/3/3) in order to be packed efficiently at the front and the rear axle. The pack holds 16.3 kWh.
