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 »

Parker Hannifin races into traction motors

After years of development, the company plans to launch a new line of traction motors this summer. Parker Hannifin is an industrial motion and control powerhouse. With over $13 billion in sales last year, its products range from hydraulics to pneumatics to electric motors. But until recently, the company’s selection of motors was solely targeted at… Read more »

EVs: the Holy Grail of multiphysics

Sandeep Sovani on the evolution of computer-based engineering simulations. Before actually creating any physical prototypes, engineers build a three-dimensional virtual model of a component, and can use computer simulations to test how the design will perform in the real world. Computer-based engineering simulation early in the development process allows them to refine and validate designs… Read more »

Linear Technology’s new active cell balancer

Linear’s new addition to the battery pack systems family is what it calls a “high efficiency bidirectional multicell active balancer” (part number LTC3300). Have you heard the old adage – no two snowflakes are alike? Well, the same goes for cells in a battery pack. No matter how precise the manufacturing techniques, there will always… Read more »

Working together: avoiding EVSE-to-vehicle interoperability issues

Intertek’s Rich Byczek on avoiding EVSE-to-vehicle interoperability issues.   Back in January, Plugincars.com published an article by Colby Trudeau – a Honda Fit EV owner, Plug In America volunteer, and electrical engineer at Qualcomm Technologies – that detailed his charging troubles using Ecotality’s Blink charging stations at work. Trudeau found that after about 20 minutes… Read more »

It’s in the details: Digatron Firing Circuits’ new stop-start testing rig

Digatron Firing Circuits’ new stop-start testing rig examines the limitations of lead-acid batteries and the inadequacy of traditional static tests. As the battery in a stop-start system ages, the fuel efficiency advantages are curtailed. It’s a real problem found in some first-generation systems, and has led many to question the methodology used in urban-efficiency tests…. Read more »

Workplace charging: employers face a maze of issues when considering EV charging

The charging experts talk workplace EVSE: free vs fee, Level 1 or 2, ROI, networking and more.  After charging an EV at home, the workplace is the next logical locale to “fill ‘er up.” It’s a place where vehicles generally spend long hours parked. It’s a predictable daily route. And with access to charging at… Read more »

Rich Byczek on delayed battery overheating and stranded energy

(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) EV standards gaps: Intertek’s Rich Byczek on two of the biggest safety concerns centered around batteries. The EV industry is young and evolving quickly – too quickly, in some cases, for the standards community to keep up.  The competing charging standards provide the most obvious example. There are… Read more »
