Researchers track lithium ions in a fast-charging battery
A team of scientists led by the DOE’s Brookhaven National Laboratory and Lawrence Berkeley National Laboratory has captured in real time how lithium ions move in lithium titanate (LTO), a fast-charging battery electrode material made of lithium, titanium and oxygen. They discovered that distorted arrangements of lithium and surrounding atoms in LTO “intermediates” (structures of… Read more »
Trump administration guts air pollution standards
As expected, the Trump administration has announced a rollback of federal fuel economy regulations, a move that some estimate will increase annual US carbon emissions by as much as 25 percent, as well as increasing fuel costs for consumers and putting the US auto industry at a competitive disadvantage. The administration says weakening the standards… Read more »
Volkswagen explains why batteries, not fuel cells, are the right choice for passenger cars
The debate over hydrogen fuel cells refuses to go away. The founders of Tesla considered hydrogen and other energy storage media before deciding that batteries were the best choice for electric powertrains, and have explained their reasoning in great detail several times since. Toyota, on the other hand, continues to insist that fuel cell vehicles… Read more »
The battery that breathes—Freudenberg’s pressure compensation system
EV batteries require pressure compensation both under normal operation and during emergency ventilation. Freudenberg Sealing Technologies’ DIAvent component combines these two functions into a single design, which will be used in the ABT e-Caddy and ABT e-Transporter, two Volkswagen vans that are popular in Europe and Mexico. To reduce battery weight and size, ABT uses… Read more »
Tesla Model Y uses a heat pump to reduce range loss in cold weather
Cold weather poses a challenge for EVs (though hardly a deal-breaker, as thousands of Norwegian drivers can attest). Not only does battery performance take a hit in low temperatures, but the resistance heating systems used in most EVs consume power, reducing range. Tesla has addressed that issue with the design of the Model Y, which… Read more »
Are EV drivers really costing states gas tax revenue?
US states have been on an EV-taxing spree over the last couple of years. Many states have established or increased annual taxes on EV ownership—including supposedly EV-friendly states like Oregon and Washington. Proponents of the tax increases invariably argue that they’re needed to make up for a growing shortfall in gas tax revenues (in an… Read more »
Colorado to allow direct sales model—good news for Tesla and Rivian
The tedious and complicated war between Tesla and the auto dealers continues to drag on. At present, the country is a patchwork—some states explicitly allow Tesla’s direct sales model, some explicitly prohibit it, and in others some sort of compromise has been reached. Tesla recently won an important battle in Michigan, and now it appears… Read more »
Canada approves Koben Systems’ GENIUS energy management system
Measurement Canada has approved revenue-grade metering for Koben Systems’ GENIUS, an energy management system for residential, retail and commercial sites. GENIUS serves as a micro-grid controller that can integrate solar, battery storage, wind, generators and EV technology. Replacing the conventional electrical panel, GENIUS enables control and monitoring of energy consumption for individual circuits. The panel… Read more »
ROCSYS automates charging stations with soft robots
ROCSYS founder Crijn Bouman is no stranger to innovation. A self-described “entrepreneur at heart,” Bouman has led two Netherlands-based startups in cleantech, software, and electronics. When his first EV fast charging equipment company Epyon was acquired by ABB almost a decade ago, he stayed on as Head of Product Management for its charging portfolio for… Read more »
