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 »
BMW partners with SOLARWATT to offer solar systems in Germany
Electric vehicles and rooftop solar power are natural partners for several reasons. BMW has just announced a partnership with a Dresden-based company called SOLARWATT to offer deals on photovoltaic systems to drivers of BMW’s upcoming i3 and i8 plug-ins. The German automaker plans to start selling its i3 EV later this year, and its i8… Read more »
EVE racer demonstrates new battery management and electronic sensor systems
Two sensors attached at the sides of the batteries measure the magnetic field generated by the flow of electrical current in order to determine the battery’s level of charge.
Researchers discover memory effect in Li-ion batteries
Scientists at the Paul Scherrer Institute (PSI) and the Toyota Central R&D Labs have reported a memory effect in lithium-iron phosphate (LiFePO4) batteries that appears after only one cycle of partial charge and discharge. Memory effects are well known to users of nickel-cadmium and nickel-metal-hydride batteries. If these batteries are recharged repeatedly after being only partially… Read more »
New Sendyne IC greatly increases dynamic range of current measurement
This week brought exciting news for fans of measuring current through resistive shunts. Sendyne Corp. has announced the new SFP100, a high precision current sensing IC that extends the range of accurate current measurements by at least an order of magnitude. With the Sendyne SFP100, ultra-low resistance and low-power consumption shunts can now be used… Read more »
KAIST discovers method to extend Li-air battery life
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have discovered a means to extend the lifetime of lithium-air (Li-air) batteries, a technology that offers the promise of higher energy densities than those achievable with conventional lithium-ion batteries. They report their findings in the February issue of the journal ChemSusChem. Li-air batteries are… Read more »
Tesla stock blasts off as sales exceed target and profit predicted
It’s no April fool. Tesla Motors has announced that it sold 4,750 units of its Model S electric sedan in the first quarter, cruising past the target of 4,500 that it set in its February shareholder letter. As a result, the company will adjust its Q1 financial guidance from achieving an operating profit (which excludes… Read more »
Oak Ridge researchers give solid Li-ion electrolytes a new spin
Their novel approach offers an advantage in terms of safety and also results in a broad (5 V wide) electrochemical window.
VIDEO: A Model S gives its all in the name of safety training
In this new video, aimed at emergency personnel, rescue experts Brock Archer and Ron Moore explain the special issues faced by first responders to EV accidents.
