Good news for EV drivers: the dreaded war between the two major DC fast charging standards doesn’t look like it’s going to happen. At least two of the potential combatants are working amicably together. BMW and Nissan have teamed up to deploy a network of 120 public dual-standard DC charging locations across 19 states (pictured… Read more »

Porsche going ahead with Mission E EV
Is that an electrically powered Porsche approaching in the distance? The German sports car maker has given the green light for a project called Mission E, with the aim of launching a new EV by the end of the decade. Porsche also announced a major program of expansion and upgrades at its Stuttgart-Zuffenhausen plant, which… Read more »
Joint Center for Energy Storage Research looks beyond Li-ion for battery advances
The Joint Center for Energy Storage Research (JCESR), a consortium of national labs, universities, and private firms, was founded in 2012 with funding from the DOE with the objective of developing a battery five times more powerful and five times cheaper than the current state of the art within five years. At the recent Bay… Read more »
What does Elon Musk think of the Apple iCar?
There’s no longer any doubt that Apple is doing some electric vehicle R&D. Whether an actual iCar will eventually disrupt the dinosaurs of Detroit remains to be seen, but a Greek chorus of auto industry insiders is already warning the champions of Cupertino not to do battle with this dragon. A recent Fortune article ridiculed… Read more »
Scrap tires transformed into supercapacitor electrodes
Some of the 300 million tires discarded each year in the US could be recycled and used in electrodes for supercapacitors, using a new technology developed at Oak Ridge National Laboratory and Drexel University. The process is described in a paper published in ChemSusChem, titled “Waste Tire Derived Carbon-Polymer Composite Paper as Pseudocapacitive Electrode with… Read more »
New ads for next-gen Chevrolet Volt attack Nissan LEAF, Toyota Prius
The 2016 Chevrolet Volt is a tour de force of engineering, a substantial step forward over its predecessor (see our cover story in the current issue of Charged). However, some EV industry observers fear that unless GM follows up on the technical improvements with some meaningful marketing, an area in which EV-makers have fallen short… Read more »
Jaguar Land Rover developing three electrification concepts
As Audi, Porsche and other luxury brands show their concepts for the electric future in Frankfurt, Jaguar Land Rover has released details of three R&D projects that explore three different levels of electrification. The Concept_e MHEV is a mild-hybrid system featuring an electric motor/generator that regenerates braking energy, stores it in a battery and uses… Read more »
New 48 V lithium battery monitoring system from ams is designed to keep things simple
Automakers are starting to produce vehicles with 48-volt power systems, and this technology is expected to catch on rapidly. Austria-based ams, which manufactures a wide range of sensors and analog ICs, has introduced a reference board for a small and simple 48 V battery monitoring system. The new board provides a complete monitoring and safety… Read more »
Enterprise adds 14 Volts to Orlando car rental fleet
Visitors to one of the world’s top tourist destinations now have the option to drive electric. Enterprise Rent-A-Car has added 14 Volts to its Orlando car rental fleet. EVs have a high profile in Florida’s tourism capital, thanks partly to Drive Electric Orlando, a local organization that partners with the major theme parks and over… Read more »
A closer look at torque ripple – minimizing its effects on electric machines
The Switched Reluctance Motor, or SRM, is often discussed as a prime choice for the next-generation EV traction motor. It is simple, robust, and arguably the least expensive of all motor types to manufacture. However, SRMs are notoriously difficult to control, and prone to emitting significant amounts of vibration and acoustic noise. The good news… Read more »
