The rebooted electric Hummer is an absurd vehicle, in some ways, but it’s an extremely well-executed absurdity. How do you review a 5-ton electric truck that accelerates from 0 to 60 mph in about 3 seconds? No other vehicle on the market is even close to direct competition. And comparing it to mass-market EVs like… Read more »
With fast- and extreme-fast EV charging, system manufacturers are quickly learning how and where to implement liquid cooling to keep powerful electronics components from overheating, failing, or causing damage. What is not broadly understood is which structural or performance characteristics of quick disconnect (QD) couplings need to be taken into account when spec’ing them into… Read more »
Battery manufacturer Sparkz has announced that it will begin construction in 2022 of a gigafactory in West Virginia, which will initially employ 350 workers, to commercialize its zero-cobalt battery. Sparkz founder and CEO Sanjiv Malhotra made the announcement at a ceremony in the state capital, Charleston, which was attended by a very diverse group of… Read more »
Fires caused by thermal runaway continue to be a significant issue in the evolution of EV battery packs. Now, as the EV marketplace approaches a tipping point, engineers are racing to address this challenge using various technologies. These include high-performance, pressure-sensitive adhesives (PSA) used in combination with thermal materials that can assist in hindering thermal… Read more »
Israeli battery tech developer StoreDot says its silicon-dominant cells have achieved a lifetime of 1,200 cycles in testing. Using a specially designed testing form factor, StoreDot’s engineers have exceeded 1,200 cycles with cells that are charged to 80% of capacity in 15 minutes, then discharged for one hour. The company says the results were achieved… Read more »
Sponsored by Hutchinson Reducing the electrical conductivity of vibration isolators with elastomer solutions When it comes to the electric vehicle market, it’s not just consumer cars that are getting all the attention. While electrified automobiles such as sedans, pick-up trucks and SUVs are becoming increasingly popular choices among buyers, EVs for commercial purposes are also… Read more »
Created by engineers with years of EV experience, the 2022 Lucid Air is a stunning debut that confronts Tesla—and Mercedes-Benz—with a new competitor. It’s been a long time coming, but the 2022 Lucid Air has been worth the wait. The new carmaker’s all-electric luxury sedan not only competes directly with the aging Tesla Model S,… Read more »
In the previous article, we looked at the various losses incurred on the AC side of the circuit while charging an EV’s battery (from the breaker in the load center to the EVSE inlet on the EV), as well as things that could be done to minimize them, either by the OEM, the electrical contractor… Read more »
Integrated-circuit (IC) maker Power Integrations has launched two new AEC-Q100-qualified, 1,700-volt-rated ICs. They are part of the InnoSwitch 3-AQ product line, and are intended for 600- and 800-V EVs and fuel cell cars, electric buses and trucks, and industrial applications such as renewable energy, battery storage, motor drives and metering. According to Power Integrations, the… Read more »
A new survey by J.D. Power found that new most drivers are finding EV ownership to be a positive experience. The US Electric Vehicle Experience (EVX) Ownership Study was conducted in October and November 2021 in collaboration with PlugShare. Respondents included 8,122 owners of 2016-2022 model-year BEVs and PHEVs, and were divided into premium and… Read more »
