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 »
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 »
Next-generation Prius Plug-in to have more electric range, wireless charging
With the entire collection of 23 Toyota and Lexus hybrid models as a backdrop, Toyota Managing Officer Satoshi Ogiso delivered an inspiring overview of the past, present and future of the Prius family at the “2013 Toyota Hybrid World Tour event in Michigan. Ogiso was one of the engineers who began developing hybrid technology at… Read more »
ZF and Levant develop active regenerative suspension
Regenerative braking is cool, so why not regenerative suspension? German transmission manufacturer ZF Friedrichshafen and Massachusetts-based Levant Power have started working together to produce just such a system. According to the companies, GenShock-technology is a fully active system for passenger cars which will combine dynamics, safety, and comfort characteristics with minimum energy consumption. The goal… Read more »
MetLife installs workplace chargers at 14 US campuses
Good grief! Insurance giant MetLife (NYSE: MET) has installed 32 Level 2 charging stations for employee use at 14 of its facilities across 10 states. According to the company, this is the largest number of stations of any non-EV industry company currently participating in the DOE’s Workplace Charging Challenge. “MetLife has a broad and deep… Read more »
Tesla Model S achieves best safety rating of any car ever tested
They’re quieter, cleaner and more fun to drive. Now it’s becoming apparent that electric vehicles are safer, too. The National Highway Traffic Safety Administration (NHTSA) has awarded the Tesla Model S a 5-star safety rating, not just overall, but in every subcategory, a distinction that only one percent of all cars tested by the feds… Read more »
