It’s reportedly close in exterior design to the production model we’ll see within months. Ram Trucks, the US truck arm of global automaker Stellantis, took the wraps off what it called the Ram 1500 Revolution BEV Concept truck on Thursday at the Consumer Electronics Show in Las Vegas. The production version of this fully electric,… Read more »

IRS releases more details about new tax credits: some foreign-assembled EVs may be eligible
We’re pleased that our pols revamped the federal EV tax credit—the new deal fixed some of the problems with the old rules, and added incentives to encourage the development of a North American supply chain for EVs and batteries. However, as is the case with any new government program, passing the law was just one… Read more »
ORNL licenses liquid-to-solid electrolyte technology to startup Safire
The DOE’s Oak Ridge National Laboratory (ORNL) has licensed a new battery electrolyte technology to Safire Technology Group, a battery tech startup formerly known as BTRY. The collection of five patented technologies is intended to be a drop-in additive for lithium-ion batteries. It’s designed to prevent explosions and fire from impact by altering the electrolyte… Read more »
Engineers find a novel way to control dendrite propagation in solid-state batteries
Solid-state batteries are a major focus for battery researchers, as they could offer weight and size reductions, as well as greater safety, compared to current Li-ion designs. However, they have a major drawback: dendrites, root-like structures that build up on the lithium surface and penetrate the solid electrolyte, eventually crossing from one electrode to the… Read more »
Inside Exro’s all-in-one EV powertrain technology
Exro Technologies is building a future in which an EV’s motor, drive, gearing and AC charging system are integrated into one highly compact and efficient system. Engineers are always looking for cost-effective ways to get the most range out of an electric vehicle’s battery pack. Exro Technologies is triangulating on a solution with three core… Read more »
6 tips for creating high-throughput battery production in record time
Batteries represent nearly one third of the total price of a typical EV, and there’s a push to get that down to 20% or less by the end of this decade. In an effort to lower costs and accelerate production, the EV industry has been searching for ways to make the assembly process more efficient… Read more »
A closer look at high-power interconnects and disconnects
In the electrical/electronic world, the terms interconnect and disconnect both refer to a means of joining two sides of a circuit together. The subtle—and entirely informal—difference is that an interconnect is directly or manually operated (inserting a plug into a jack, for example) while a disconnect is indirectly or automatically operated, for example the moving… Read more »
How to make heavy-duty electric trucks work in practice
Fleets tested Volvo VNR Electric Class 8 tractors for three years: Here’s what they learned. Large commercial trucks and other heavy equipment have run on diesel fuel for many decades now. Requirements for more aggressive emission after-treatment and the hardware to achieve that add cost and complexity for fleet operators. Rising fuel-economy standards during the… Read more »
Researchers aim to improve rare-earth-free magnets through microstructure engineering
Researchers from the DOE’s Critical Materials Institute (CMI) and Ames National Laboratory have developed a new method of manufacturing manganese bismuth (MnBi) magnets based on microstructure engineering. They describe their wok in “Engineering microstructure to improve coercivity of bulk MnBi magnet,” published in the Journal of Magnetism and Magnetic Materials. Permanent magnets used for electric… Read more »
Here’s why oil and gas companies are racing to invest billions in EV charging
As regular Charged readers know, oil companies have been on an EV charging spending spree. They’re getting into public charging in a big way, and it goes far beyond just installing chargers at their gas stations. Oil majors including bp, Shell and Total have been buying up companies at all points along the charging value… Read more »
