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 »

Smith Electric Vehicles: the long haul and the short end of the stick

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 »
