A pair of Vanderbilt University researchers have developed a battery management device that could increase the useful range of a battery pack by controlling each cell individually. Ken Pence, Professor of the Practice of Engineering Management, and Tim Potteiger, a PhD student in electrical engineering, used the open-source Tesla battery to model their technique, adding… Read more »

SAE J2954 Recommended Practice enables automated wireless charging to 11 kW
SAE International has published a new Recommended Practice (RP), SAE J2954, which provides the first worldwide specification for wireless power transfer (WPT) up to power levels of 11 kW (WPT 3). This follows the organization’s previous Technical Information Report J2954, which dealt with power levels up to 7.7 kW (WPT 2). The new RP also… Read more »
Is Tesla’s Model X the ultimate EV? Extended drive review
Tesla set out to build not the best electric cars, but the best cars, and many would argue that it has achieved that goal. Models S and X are two of the most advanced, feature-rich autos on the market today. In a sense, Model X must be considered the ultimate, as it has more interior… Read more »
New report analyzes global market for recycled lithium and cobalt
In a new analysis of the global end-of-life value chain for lithium-ion batteries, consultancy Creation Inn predicts that the total amount of recycled lithium could reach 5,800 tons (30,000 tons lithium carbonate equivalent) in 2025, 9 percent of the total lithium battery supply, while the amount of cobalt from recycled batteries is expected to reach… Read more »
Raption 50 DC fast charger uses a modular design to maximize uptime
Barcelona-based charger manufacturer Circontrol presented its new Raption 50 DC quick charging station at the recent EVS30 exhibition in Stuttgart. The Raption 50 series is designed to maximize its uptime and availability for users, thanks to its modular design, which features four individual power packs that deliver 12.5 kW each. If one power pack fails,… Read more »
BMW to showcase 5 EVs at LA show
The BMW Group will present 5 EVs at the 2017 Los Angeles Auto Show, including one new production vehicle, the BMW i3s. BMW recently reported that EVs and PHEVs now account for 5.5% of total sales in the US. By 2025, the company plans to offer 25 electrified models, 12 of them pure EVs. The… Read more »
New in-depth video review compares Model 3 with Model S
Tesla’s Model 3 is floating in a strange sort of scarcity-induced stealth mode. Mainstream auto mags can’t seem to get their hands on units to review, but video reviews from owners and internet-era citizen journalists are starting to appear: Doug DeMuro, writer of the Oversteer column on Autotrader; Trevor Page and Kenneth Bokor, the founders… Read more »
ODU offers the complete EV connections solutions for OEM and Teir 1 customers
Sponsored by ODU-USA Although mass-produced hybrid and electric cars have been commercially available since the 1990’s, the field is still very much in an evolutionary state, driven largely by two key factors: Greater vehicle range Shorter stops at re-charging stations The second of these does not necessarily imply actual re-charging. A more recent innovation involved… Read more »
BMW takes steps to ensure more responsible production of cobalt
And the dirty little secret of EVs is…cobalt. The metallic element is used in significant quantities in EV batteries. Unfortunately, about half the world’s cobalt comes from the Democratic Republic of Congo (DRC), a war-torn land in which working conditions are bad, and child labor is common. In 2014, as many as 40,000 children worked… Read more »
Former EPA official: US automakers’ EV strategies are irrational
These days, not a week goes by without an announcement of some major electrification initiative from a major carmaker: Nissan’s new LEAF is coming to the US soon, GM is actually advertising its Bolt EV, VW and Daimler have each announced a range of new EVs (for China, at least), and Volvo and Jaguar have… Read more »
