EnviroSpark runs its own EV charging network and helps others with installations, including Tesla, Volkswagen and Ford. The parlous state of public charging reliability has emerged as a major roadblock to wider EV adoption, and the entire industry is going through a soul-searching phase, trying to identify the roots of the problems and correct them….

Battery cell qualification for EVs: Lucid’s cell specialist discusses the complicated process
Q&A with Lucid’s Battery Cell Technical Specialist Maithri Venkat. When it comes to battery cells for EVs, one size definitely doesn’t fit all. The properties of a particular cell act as constraining factors for every aspect of a vehicle’s design—and not only for vehicle performance parameters such as range and power, but for the development… Read more »
Exclusive: Black Book used EV values to include Recurrent battery-condition data
The biggest question in buying a used EV is whether its battery is any good and how much range is left. We’re a little closer to an answer now. The Black Book used-car valuation service said Tuesday it would incorporate battery-condition data from Recurrent into its used-EV values. That data lets Black Book vary what… Read more »
Video: Qnovo uses BMS software to increase battery lifespan and charging speed
It’s widely believed that frequent DC fast charging stresses a battery, shortening its useful lifetime. However, the long-term effects of frequent fast charging can be mitigated with properly designed charging limits. (Battery data specialist Recurrent recently released the results of a study on the subject.) Can BMS software eliminate this problem and push the limits… Read more »
The real reason Hertz is selling EVs
It’s the kind of headline EV boosters hate, and EV boo-birds trumpet: just two years after announcing that it would buy 100,000 Teslas and a raft of other EVs, rental giant Hertz announced that it would sell 20,000 of its Teslas and replace them with tried-and-true gas-guzzlers (at this writing, the company is offering around… Read more »
Carbon Brief offers a raft of resources to debunk misinformation about EVs
Here at Charged, we don’t devote much time to debunking anti-EV misinformation—the enemies of the future flood the zone with FUD 24/7, and responding to even a fraction of it might leave no time for anything else. However, a recent article in Carbon Brief is so comprehensive and well-researched that we just had to bring… Read more »
New studies indicate that battery-electric aircraft with 800 km range could be practical
Several companies are working on battery-electric aircraft, but electric aviation is a tougher nut to crack than electric cars, for physical reasons. It simply takes a lot more energy to keep an aircraft aloft than it does to propel a vehicle along a road, and every additional pound of battery weight takes a steep toll… Read more »
Eaton shows a couple of innovative scalable EV charging solutions at CES
Electronics giant Eaton has broken some new ground in the EV charger segment, and the company is showing two innovative new charging systems at CES. Eaton’s Sai Murahari, EVCI Product Manager, showed Charged its EV Smart Breaker line of chargers, which combine an EV charger with a smart circuit breaker. The integrated device fits into… Read more »
QuantumScape’s solid-state battery cell achieves milestone in testing: 1,000 charging cycles
In recent A-sample tests at the laboratories of PowerCo, the Volkswagen Group’s battery company, a solid-state battery from QuantumScape achieved more than 1,000 charging cycles while retaining more than 95 percent capacity. This translates to a potential battery life of 500,000 km with no significant loss of vehicle range. Solid-state battery technology promises longer ranges,… Read more »
Is curbside charging the solution for the Plight of the Drivewayless?
The Plight of the Drivewayless—those poor souls who live in urban locales where they can’t charge their EVs at home—has emerged as a major drag on the speed of EV adoption. Solutions from the clever to the silly have been proposed, but if we look at dense cities where adoption is already well advanced, we’re… Read more »
