Scientists at Oak Ridge National Laboratory (ORNL) have used new techniques to create a composite that they claim increases the current capacity of copper wires, providing a new material that can be scaled for use in ultra-efficient, power-dense EV traction motors. The research is aimed at improving the performance and life of components such as… Read more »

Tesla Model 3 logs 100,000 miles with little reported battery capacity loss
There are plenty of high-mileage Teslas on the road, but so far we’ve heard from few Model 3 owners who’ve passed the 100,000-mile mark. Kazi Imam is one driver who’s passed that milestone, and he recently told his story to Electrek. Imam logged 100,000 miles on his 2018 Model 3 Long Range in just over… Read more »
Li-ion battery capacity for new EVs sold in the US reached a record high in 2019
Battery electric vehicles (BEVs) captured a record amount of total plug-in vehicle battery capacity sold in 2019, with 17.4 gigawatt-hours of total capacity. Plug-in hybrid electric vehicles (PHEVs) accounted for a smaller portion of total vehicle battery capacity due to their lower sales volumes, and because they require smaller battery packs than BEVs. PHEV sales… Read more »
Volkswagen ID.4 and Nissan Ariya bring EV drive to compact crossovers…chasing Tesla Model Y
Can new electric entries in a hugely popular segment convince US buyers to buy EVs from Nissan and VW as family vehicles? Two new battery-electric models from major global car brands are about to bring electric cars into a category where they’ve been notably absent: family crossover utility vehicles. The 2021 Volkswagen ID.4 and 2022… Read more »
Encapsulant provides excellent corrosion protection of critical PCB components in EV electronics (Whitepaper)
Sponsored by Dymax Corporation By Dr. Aysegul Kascatan Nebioglu and Chris Morrissey Components on printed circuit boards or electronic modules in electric vehicles are often required to be covered with polymeric encapsulants to protect them against environmental conditions such as moisture, chemicals, and rapid and extreme temperature changes, while providing mechanical support and electrical insulation….

Accelerated electrode drying could reduce battery production cost
A new EPIC project coordinated by Karlsruhe Institute of Technology (KIT) is aimed at accelerating the drying of electrodes for lithium-ion batteries, increasing the energy efficiency of this process and reducing production cost. KIT says innovative electrode drying management can reduce the cost of battery production and improve environmental performance. The quality of Li-ion battery… Read more »
Teardown expert Sandy Munro compares Tesla, Nissan, Jaguar inverters
When it comes to automobiles, Sandy Munro knows whereof he speaks. His company specializes in taking new cars apart and analyzing every little bracket and screw—what it’s made of, who made it, and how much it cost. Charged was fortunate enough to have Sandy present a couple of video sessions at our Virtual Conference on… Read more »
Teardown expert Sandy Munro compares 10 leading EV motors in new video
Auto manufacturing expert Sandy Munro knows what makes cars tick. For years, he and his company have performed teardowns, taking new cars apart and analyzing every little bracket and screw—what it’s made of, who made it, and how much it cost. This week at the Charged Virtual Conference on EV Engineering, Sandy compared an assortment… Read more »
Oxis Energy’s ultralight Li-sulfur batteries are aimed at aviation
Oxfordshire-based Oxis Energy has been working on lithium-sulfur battery technology since 2004 (Charged has reported on the company several times over the years). In a recent article in IEEE Spectrum, the company’s Head of Battery Development and Integration, Mark Crittenden, explains why lithium-sulfur tech is uniquely suited to electric aviation. Weight is a critical constraint… Read more »
Elon Musk expects manufacturing to be Tesla’s ace in the hole
Tesla is increasing its focus on perfecting its manufacturing process. As Zachary Shahan writes in a recent CleanTechnica article, “the machine that builds the machine” just may be Elon Musk’s favorite phrase these days. In fact, Musk expects Tesla’s manufacturing prowess to give it an edge over other EV-makers. “Tesla’s long-term competitive advantage will be… Read more »
