EVs haven’t been around long enough, or in great enough numbers, for any large-scale market in replacement batteries to develop. However, Toyota’s Prius hybrid went on sale in the US in 2000, and has sold well over two million units. There’s a lively market for replacement batteries, with both OEM and aftermarket options available. For… Read more »

Prius Prime Advanced: the prince of PHEVs
Looking for an objective review of the Toyota Prius Prime Advanced? Sorry, you’ll have to look elsewhere. I’m one of “the pious” – annoying Prius drivers who sing the praises of our favorite hybrid vehicle to anyone who will listen. I’ve owned three Prii (and yes, replaced batteries on two), and this is a completely… Read more »
City of London introduces emissions-based parking fees
Fortunately, the famous London Fogs are a thing of the past, but the UK capital continues to take steps to improve air quality. Drivers in central London must pay a hefty Congestion Charge of around £11.50 (about $15), subject to discounts for “Ultra Low Emission” vehicles. Now the city’s famous financial district, known formally as… Read more »
Penn State researchers develop cold-weather fast charging method for Li-ion batteries
Fast charging cold Li-ion batteries comes with the risk of lithium plating. When metallic lithium is formed in a battery, it can severely reduce battery lifespan and increase instability. Researchers from Penn State have suggested a solution to that problem that can provide 15-minute fast charging and a twelve-year battery lifespan in temperatures as low as… Read more »
Mitsubishi Outlander PHEV delivers the goods
As a tree-hugging greenie, I tend to be prejudiced against SUVs, but after a week with the Mitsubishi Outlander PHEV, I couldn’t really find anything not to like. This medium-size crossover drives great, it’s comfortable, and it has all the high-tech goodies we’ve come to expect. The electric range of 22 miles is enough to… Read more »

A closer look at DC-DC converters
As far as we know, all EVs in production by major automakers use a conventional lead-acid battery for the 12 V system (surprising, but true – more on why in a bit) and this battery needs charging, just as it does in an ICE vehicle. While you could hang an alternator off the traction motor… Read more »
Wall Street comfortably digests Tesla’s Q2 results
Tesla isn’t like other companies, and you can never tell how Wall Street will react to a particular quarterly earnings report. Like gourmands digesting a culinary oeuvre, those of us who aspire to be seen as wise have learned to wait a day or so to let things settle before passing judgement (or making stock… Read more »
