Porsche foresees 800-volt DC charging
If there’s one thing everyone can agree on about EVs, it’s that ranges need to become longer. That means battery capacities need to grow, and therefore charging levels will have to increase as well, if charging times are to stay the same (or, preferably, become shorter). One company that’s been working on higher charging levels… Read more »
Atieva’s electric van meets a Ferrari and a Model S on the drag strip
Atieva has an office in Silicon Valley, an impressive team of engineers led by former Tesla star Peter Rawlinson, a flashy web site, and now, finally, a prototype vehicle, a delivery van that can do 0-60 in 3.08 seconds. “Edna,” a converted Mercedes Metris van, made her debut with a video of a drag race… Read more »
Is Toyota warming up to plug-in vehicles?
Toyota has earned the disapproval of many in the EV community for setting up what many see as an artificial competition among different powertrain technologies. Its execs have made statements disparaging battery EVs, and its Lexus subsidiary has run ads mocking EVs. Lately however, there have been signs that the world’s largest automaker may be… Read more »
Peugeot Citroën to produce 4 EVs, 7 PHEVs by 2021
PSA Peugeot Citroën presented its new electrification strategy at a recent company event. The group plans to consolidate development on two global modular platforms – CMP and EMP2 – that will be the basis for legacy ICE vehicles, EVs and PHEVs, starting in 2019. The Common Modular Platform (CMP), developed in partnership with Dongfeng Motors,… Read more »
Improving aerodynamic modeling: Combining airflow dynamics with vehicle-handling models
Tuning a vehicle’s aerodynamic features is nothing new. Engineers have been using wind tunnels for decades, and more recently they’ve also employed computational fluid dynamics (CFD) software to reduce drag, minimize noise and increase stability by preventing undesired lift forces. In the expanding world of EVs, car builders are doubling down on efforts to push… Read more »
Solar synergies: The market for solar carports expands alongside growing interest in EVs
A solar carport is the perfect complement to an EV. Not only does it ensure that your pretty new automobile, and the electrons powering it, stay clean, but it keeps things cool, making for slightly more efficient charging, and it serves as a visible advertisement for the new energy future. Charged recently spoke with the… Read more »
2016 Audi A3 Sportback e-tron delivers performance and practicality
The selection of plug-in vehicles available to US buyers continues to grow steadily – it now stands at 27 models, with several more expected this year. The latest entrant to the market is the 2016 Audi A3 Sportback e-tron, the German luxury brand’s first plug-in model available in the US. Every time a new plug-in… Read more »
Complete Coach Works offers a remanufactured electric bus for the cost of a new diesel
Urban transit buses represent a prime opportunity for electrification. Their typical duty cycles allow them to be conveniently recharged at terminals, and the savings on fuel and maintenance can be enormous. Furthermore, cities around the world are revitalizing and beautifying their downtown districts, so getting rid of noise and diesel smoke is a welcome benefit…. Read more »
New material shuts down batteries at high temperatures and restarts when it cools
Stanford researchers have invented a new technology that could eliminate thermal runaway in high-energy-density batteries. Thermal runaway refers to a chain reaction in which an increase in temperature causes further increases in temperature and uncontrollable release of energy. In “Fast and reversible thermoresponsive polymer switching materials for safer batteries,” published in Nature Energy, Professor Zhenan Bao and… Read more »
