Many have posed the question of why the EV market in Europe has lagged behind the market in the US, considering the Continent’s higher fuel prices and strong green tradition. While there are several plausible answers, on closer examination the question itself makes little sense, because in fact there is no European EV market, but… Read more »

Multiphase cooling: CapTherm’s technology takes the heat off
Canada’s CapTherm Systems’ multiphase cooling technology could take the heat off of EV batteries and charging stations more efficiently, taking up less space using fewer materials while improving longevity and performance. Charged takes an early peek at this innovation before it goes commercial next year. If you’ve never dropped your smartphone 10 feet onto pavement,… Read more »
BMW i3: The launch of many firsts
When you’re writing about the dawn of a new industry, “firsts” and “milestones” come along so often that they may start to lose their novelty. However, the BMW i3, which was officially “launched” in July, and is scheduled to go on sale next year, boasts an impressive number of innovations that has the EV press… Read more »
Plug-in fleets: small challenges, huge savings
Four plug-in truck companies talk to fleet managers about electrification opportunities Plug-in vehicles are different. Aside from the obvious changes in technology, they present a different financial model for corporate number crunchers. This means some challenges for those pitching EVs and PHEVs to fleet operators. Fortunately for the EV industry and the fleets of the… Read more »
Resonating with the OEMs: WiTricity’s wireless energy transfer technology
WiTricity hopes to leverage a wireless energy transfer breakthrough out of MIT into a commercial solution with far-reaching potential Inside a standard electrical transformer are two coils that transfer power wirelessly. They utilize the principle of magnetic induction, sending energy from a primary coil to a secondary coil without a direct electrical connection. Inductive chargers,… Read more »
A closer look at back electromotive force
Why motors generate and generators motor In a previous article I took a closer look at regenerative braking, and mentioned an old engineering saying that every motor is a generator and every generator is a motor (along with the caveat that some are more suited to the opposite purpose than others). This time around I’ll… Read more »
Plug In America research: Tesla Roadster battery longevity exceeds projections
By Tom Saxton, Chief Science Officer, Plug In America Many current and prospective electric vehicle owners are curious to better understand battery pack longevity. There’s plenty of technical data on how batteries lose capacity with use, but a lot of that testing subjects the batteries to extreme and rapid charge/discharge cycles, very unlike the much gentler use… Read more »
August plug-in sales best in history – Volt, LEAF, Prius smash records
Break out the Champagne! August was the best month ever for US plug-in vehicle sales, as 11,073 new owners got charged. Year-to-date sales (58,662) have already surpassed sales for all of 2012 (52,581). The surge was broad and deep – the three leading models had huge increases, the top two set new records, and even… Read more »
eVgo opens first California charging station – and thereby hangs a tale
NRG eVgo (ee-vee-go) has announced the opening of a public charging station at Westlake Shopping Center in Daly City, California. The new Freedom Station offers both level 2 and DC fast charging, and is the first of seven such sites that eVgo plans to open at Kimco Realty-owned retail centers (NYSE:KIM) in California this year….

GE and Berkeley researchers hint at new water-based battery
It sounds like an intriguing idea: a new type of battery that uses water-based solutions of inorganic chemicals that can supply high energy density by ferrying more than one electron at a time. Scientists at GE Global Research and Lawrence Berkeley National Laboratory are working on such a system, which they call the a “flow”… Read more »
