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 »

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 »
Furrer+Frey proposes tractor swapping for long-haul trucks
While short-haul applications such as local delivery trucks, port drayage trucks and city buses are perfect candidates for electrification, long-haul trucking will likely prove more of a challenge, because of battery-electric vehicles’ limited range. Now Furrer+Frey, a Swiss firm that provides a wide range of rail transport products and services, has proposed a simple, low-tech… 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 »
Electric torque vectoring: Q&A with GKN’s Advanced Engineering Director (Full Interview)
Torque vectoring technology is generally defined as a vehicle’s ability to vary the power to each wheel. Quickly controlling the torque applied to the wheels independently of one another allows the driving characteristics of a vehicle to be improved in significant ways – more stability, more responsiveness and more agility. A conventional differential distributes the… Read more »

Advancing BMS: Linear Technology launches its fourth-generation battery stack monitor
Engineers use battery management systems (BMS) to prevent problems that occur in Li-ion batteries when they are over-charged or over-discharged, including premature capacity loss and thermal events. A BMS ensures precise control and keeps the individual cells balanced, which is critical to extracting the most useful energy from a pack. Fortunately for EV systems designers,… Read more »
