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 »

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 »

A closer look at wire bonding

Wire bonding technology – widely utilized in the microelectronics and power electronics industries since the 1970s – is finding its way into interesting new applications in the growing EV industry – in particular, battery connections. We’re quite certain that a few EVs are using wire-bonding technology for production battery pack connections, but Charged was unable… Read more »

Seaward’s new handheld charge point tester will help bring quality control to a new level

There is no doubt that the early days of charging infrastructure rollout had some bumps in the road. Plug-in vehicles interact with the outside world in a much more complicated way than legacy gas-guzzlers do, which led to early interoperability issues. The automakers needed to quickly learn how to work with many infrastructure and hardware… Read more »

WAVE wireless charging helps transit agencies save money by going electric

Wireless charging technology is almost ready for the big stage. Qualcomm has demonstrated its Halo system in various vehicles, including the Drayson B12/69 electric race car. Evatran’s Plugless aftermarket system is now commercially available for the Volt and the LEAF, and a Model S-compatible version is coming soon. Several major automakers have indicated that they’re… Read more »

BMW’s X5 xDrive40e spearheads its plan to offer PHEVs in every market segment

BMW has taken a bold approach to electrification. It began test-marketing EVs in 2012 with the Active E and Mini E, and escalated to full-scale production in 2013 with the i3 EV and i8 plug-in super-sports car, which together passed the milestone of 50,000 worldwide sales in January. BMW deserves a lot of credit for… Read more »
