The world’s transportation ecosystem has hundreds of species of vehicles, each one adapted to the requirements of its particular niche. Some niches are clearly well-suited to EVs, and others are probably not. Urban delivery trucks, which typically make route-based journeys from a central depot and consume a lot of diesel fuel, can quickly recoup an… Read more »

Connecting the dots: EV charging hardware, software and services
More and more organizations are finding that it makes sense to offer EV charging to their employees and/or customers. However, installing and administering the charging stations, especially across a large enterprise, can be a complicated proposition. Not the least of the headaches is finding a way to quantify the return on investment (ROI) in charging… Read more »
Web of Power: Spider9’s Operating System for Energy
Spider9 weaves a matrix for stationary energy storage and shows that when it comes to fitting battery technology into electric vehicles, it’s not all for one and one for all. Many real-world technologists and engineers take inspiration from the worlds of science fiction, where recurring themes of systems theory take shape in the Grid of… Read more »
EADS and Siemens electrify aviation
Electric aircraft may be taking to the skies sooner than you think. EADS (the parent company of Airbus) and various partners have several “E-aircraft” research projects underway, and have already flown a couple of electrified airplanes. In 2010, EADS Innovation Works (IW) and Aero Composites Saintonge (ACS) flew a single-seat, 375 lb plane called the… Read more »
Cadillac ELR keeps it quiet
Naturally, the 2014 Cadillac ELR’s interior is silent when running on battery power. The luxury coupe’s engineers went to great lengths to keep it that way when the range-extending generator kicks in. ELR uses active noise cancelling, a technology that samples noise and generates a sound wave with the same amplitude but with inverted phase,… Read more »
ChargePoint launches new financing program for EV charging stations

Chargepoint offers trade-in credit to Blink charger operators
As some analysts are predicting spectacular growth in the public charging market, something of a Wild West atmosphere is developing. Last month, Ecotality, one of the country’s largest network operators, filed for bankruptcy. Last week, Florida-based Car Charging Group announced that it would purchase Ecotality’s Blink charging network. Now Chargepoint, another giant network, is looking… Read more »
Dual battery pack could give next-generation Tesla unprecedented range
Is Tesla working on a new type of hybrid pack that combines two different battery technologies to deliver a huge increase in range? This question has been floating around the discussion groups for a few months, but several outlets reported it as breaking news this week after a couple of stock analysts discovered the story… Read more »
The challenges of battery state of charge measurements
Your BMS’s fuel gauge is lying to you. Here’s why that’s not a big deal. Battery management systems (BMSs), and the fuel gauges in them, are a part of daily life for almost everyone. You’ll find them in vehicles, laptops, cell phones, grid-attached energy storage – basically, anything that does work and needs to be plugged in,… Read more »
Connecting Europe’s charging networks
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 »
