The technical reasons Tesla would limit supercharging speed, and other practical charging considerations

Recently, a bit of a kerfuffle kicked up when a Tesla Model S owner noticed that the maximum charge rate for his car on the Supercharger network had suddenly been cut from 120 kW down to 90 kW, apparently the result of too many fast charge cycles. Tesla’s explanation was, essentially, that many things can… Read more »

The US is generating plenty of power, ready and waiting for EVs

DOE’s Electricity Advisory Committee meets for the first time since the new administration took office. On March 29 and 30, the DOE’s Electricity Advisory Committee (EAC) held its first meeting of 2017. The EAC has 31 members from across the country, representing all aspects of the electricity sector. Its focus includes generation, grid security, and… Read more »

Tritium opens a US office to support its stylish and capable DC fast charging products

Success stories sometime spring from unlikely places, especially during times of rapid, disorienting technological change. Consider the case of Tritium, a small independent company based in Australia, half a world away from the centers of automotive power, that has grown to become one of the world’s leading manufacturers of DC fast chargers. When asked about… Read more »

EV fast charging in transition: What’s currently installed, coming soon and still years away?

Phoenix Contact discusses the upcoming transition phase for DC fast charging We receive a lot of press releases at Charged about plans for next-generation DC fast charging. It’s easy to lose track of exactly what is currently installed, what is coming in the near future, and what is still a few years away. Despite all… Read more »

New Eagle teams up with Inventev to offer electric Ford Transit vans

The business case for electrifying commercial vans would seem to be a no-brainer – the savings on fuel and maintenance are substantial and demonstrable. In the real world however, pilot projects are plentiful, but substantial orders have been slow to materialize. More than one promising startup has gone under while waiting for fleet customers to… Read more »

LORD is developing a rotary band brake aimed at automotive thermal management systems

“Any product that uses less power and has high torque in a small package could be of interest to the EV space,” LORD’s Edward Conner told Charged. We were discussing the company’s electromagnetically actuated rotary band brake technology, and we naturally asked a lot of questions about its potential applications for EVs. The core of… Read more »

Carpenter Technology develops a new soft magnetic alloy with key benefits for EV motors

Electrical steels are soft magnetic materials found at the heart of electric motors. They’re typically manufactured in cold-rolled strips, cut into shapes to make laminations and then stacked together to form the stator and rotor of a motor. These specialty steels are tailored to produce certain magnetic properties, and have a magnetic flux density (key… Read more »

Hyundai launches Ioniq with three distinct powertrain choices: EV, PHEV and hybrid

In the short history of the modern EV industry, it’s been common for automakers to launch plug-in cars under a new brand or model – particularly those companies who are serious about selling EVs at scale. Or, at least the ones that want to appear serious about selling a lot of EVs. Even though Hyundai… 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 »

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 »
