Lightweight electromobile with ROHACELL body crosses Australia almost exclusively on wind energy

Green Car Congress

The Wind Explorer pilot vehicle is a two-seated electromobile that weighs just 200 kg (441 lbs) and with a range of 400 kilometers (249 miles) per battery charge. Its lithium-ion batteries, based on yet another Evonik technology, are charged by a mobile wind turbine or in the conventional way from the power grid.

DeepDrive to unveil new central drive unit at IAA Mobility

Green Car Congress

The key enabler for the dual-rotor concept is a new distributed winding concept with a slot-filling factor above 80%. The patented DeepDrive dual-rotor, radial flux machine combines an inner and outer rotor with two air gaps and benefits from very high material utilization and lowest iron losses.

Electric motor company YASA enters innovation agreement with global automotive manufacturer for hybrids and EVs

Green Car Congress

The Yokeless And Segmented Armature (YASA) topology is a type of axial flux motor that has no stator yoke, a high fill factor and short end windings which all increase torque density and efficiency of the machine. The axial flux enables high power densities to be achieved at relatively low speeds (2000-9000rpm). Earlier post.).

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Stanford / SLAC’s new lithium-polysulfide flow battery design compared to conventional “redox” flow batteries. The new flow battery uses only one tank and pump and uses a simple coating instead of an expensive membrane to separate the anode and cathode. Credit: Greg Stewart/SLAC).

Who Really Invented the Rechargeable Lithium-Ion Battery?

Cars That Think

Fifty years after the birth of the rechargeable lithium-ion battery, it’s easy to see its value. It was manufactured in small volumes by Exxon, appeared at an electric vehicle show in Chicago in 1977, and served briefly as a coin cell battery. Did Exxon invent the rechargeable lithium battery? But then Exxon dropped it.
