Back in October, Cambridge scientists wowed the battery world with an announcement that they had demonstrated a highly efficient and long-lasting lithium-oxygen battery. Lithium-oxygen, or lithium-air, batteries have a theoretical energy density ten times that of lithium-ion solutions, but suffer from poor cycle life. In a paper published in the journal Science, Tao Liu and… Read more »

Evercar brings its fleet of EVs to Uber, Lyft, Instacart and other on-demand services
Evercar uses short-term rentals to accelerate the potential for electric ride-sharing and delivery services. If it can clear regulatory hurdles, its electric-miles-as-a-service tools could change the growing industry. On paper, EVs seem like the perfect choice for the on-demand economy. In a world where vehicles are being pushed to spend more time on the road… Read more »
More motor options: TM4 launches new powertrain products with increased torque and speed ranges
TM4 designs electric powertrains for the most demanding vehicle platforms and duty cycles on the road. Formed as a subsidiary of the public utility Hydro-Québec, the company sells its motor and control products to manufacturers of heavy-duty trucks and buses around the world. In June, TM4 will release an update to its SUMO product line… Read more »
Improving aerodynamic modeling: Combining airflow dynamics with vehicle-handling models
Tuning a vehicle’s aerodynamic features is nothing new. Engineers have been using wind tunnels for decades, and more recently they’ve also employed computational fluid dynamics (CFD) software to reduce drag, minimize noise and increase stability by preventing undesired lift forces. In the expanding world of EVs, car builders are doubling down on efforts to push… Read more »
Tesla Model 3: What we know and what we don’t know
Tesla made automotive history on March 31, when it unveiled the culmination of its master plan to bring EVs to the masses. The company has committed to delivering a car with the parameters that pundits have identified as the tipping point for widespread EV sales: 200 miles of range and a price tag in the… Read more »
Cyber-security or cyber-resilience?
By Sam Abuelsamid, Senior Research Analyst – Navigant Research If you move, you will die. If you don’t move, you are already dead. There are countless variations on that theme but the gist is that life is full of risk and, sooner or later, it will get you. However, if you plan ahead and prepare,… Read more »
ChargePoint launches updated hardware and management platform targeting fleet operators
Large corporate and government vehicle fleets are increasingly turning to plug-in vehicles to take advantage of dramatically lower fuel, operating and maintenance costs. For the fleet manager, however, the EV infrastructure world is a lot more complicated than it is for gas or CNG vehicles, which can use a single refueling depot. In spite of… Read more »
Solar synergies: The market for solar carports expands alongside growing interest in EVs
A solar carport is the perfect complement to an EV. Not only does it ensure that your pretty new automobile, and the electrons powering it, stay clean, but it keeps things cool, making for slightly more efficient charging, and it serves as a visible advertisement for the new energy future. Charged recently spoke with the… Read more »
Tesla tests Autopilot features with secret updates
Along with electrification, autonomy and connectivity are part of a triple trend that is revolutionizing the transport sector. At least one automaker understands how closely the latter two are connected – data delivered wirelessly from Tesla vehicles helps the company to improve its Autopilot technology, as Elon Musk recently explained. “The ability to pull high-resolution… Read more »
Elon Musk: When it comes to autonomous driving, data is everything
Vehicle autonomy is developing on a parallel course with electrification. Tesla is at the forefront of this trend with its Autopilot features, keeping it a nose ahead of any potential competition from other automakers. Every day, more Autopilot-driven miles are added to the body of data that the company is amassing. Tesla said in April… Read more »
