Novelis to provide aluminum for NIO EVs
Aluminum supplier Novelis has agreed to provide aluminum for NextEV’s line of NIO EVs. NIO will use Novelis Advanz aluminum alloys to create a range of structural components and parts for its electric SUV models, which it plans to launch over the next five years. The aluminum for NIO will come from Novelis’s new $100-million… Read more »
Tesla’s chief motor engineer discusses the potential of next-generation motor technologies
Tesla spends a considerable amount of resources on basic research into EV systems – as well it should. EV technology is very young compared to that of ICE vehicles, so it’s safe to assume that, in a few short years, the aggregate of many incremental technology advances could lead to significantly better EVs. Of course,… Read more »
Mkango is developing new rare earth alloys for 3D-printed magnets
Canada-based Mkango Resources has teamed with UK-based Metalysis to develop and commercialize novel rare earth metal alloys for use in 3D-printed permanent magnets. The two companies envisage a comprehensive R&D program, taking advantage of Mkango’s knowledge about the performance characteristics and demand outlook for rare earth magnets and Metalysis’s solid-state process, which it says can… Read more »
Honda developing dynamic charging system that works at speeds up to 96 mph
At the upcoming SAE World Congress Experience, a team from Honda R&D will present a paper entitled “Study of High Power Dynamic Charging System,” which describes their work on a dynamic charging system that uses high power to charge a moving EV, with the goal of realizing an unlimited vehicle range. The current study is… Read more »
Southwest Research Institute consortium conducts independent battery benchmarking
Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »
2017 Chevrolet Bolt EV: The era of long-range, mid-priced EVs is here
The 2017 Chevrolet Bolt EV will surely be remembered as a milestone model in automotive history – and hopefully for more than just the hype that heralded it. For several years, the punditocracy has been saying that the “killer app” that would bring electromobility to a “tipping point” and build that all-important “critical mass” would… Read more »
Battery management system maker Dukosi lands £2 million in funding
Scottish battery management systems innovator Dukosi has secured £2 million in new investment funding, led by IP Group. Dukosi has developed a battery management system (BMS) that collects, processes and stores data directly at the cell. Using wireless technology, the system transmits real-time information on cell performance to support master-level control of the battery pack…. Read more »
Alstom fuel cell/battery passenger train to go into service in Germany
French train manufacturer Alstom has developed a passenger train that incorporates both fuel cells and lithium-ion batteries The company presented the zero-emission Coradia iLint at the recent InnoTrans trade fair in Berlin. The German state of Lower Saxony has ordered 14 units, according to Die Welt, and plans to put them into service in December…. Read more »
MIT researchers investigate mechanics of sulfide-based solid electrolyte material
IMAGE: Using specialized equipment, a team from MIT did tests in which they used a pyramidal-tipped probe to indent the surface of a piece of the sulfide-based material. Surrounding the resulting indentation (seen at center), cracks were seen forming in the material (indicated by arrows), revealing details of its mechanical properties. Battery scientists are the world are exploring… Read more »
