Electric vehicles are going mainstream as battery and power management technologies mature and EV charging infrastructure expands. Those advances include new wireless recharging frameworks that address ongoing concerns about EV performance, especially range.

We take a closer look at accelerating ecosystem development in this EV Special Project, considering everything from promising new chip materials and substrates to the application of quantum algorithms to the simulation of battery performance. As the EV market gains traction–on the road and at the engineering bench–emerging technologies are being brought to bear amid efforts to boost EV performance and energy efficiency.

Maurizio Di Paolo Emilio explores a range of industry efforts aimed at refining all-important charging applications that will go a long way toward solving the “range anxiety” challenge associated with electric vehicles. From testing gear to new electronic materials, those advances are entering the automotive fast lane.

Elsewhere, we survey new power management and energy storage schemes that promise to extend range and allow EVs to rely more heavily on sustainable and renewable energy sources.

Tesla’s Elon Musk predicts a three-fold increase in electricity demand as more EVs hit the road. Improved battery technology offering higher energy densities will therefore become a key component of future smart grids, hastening the vehicle-to-grid transition.

Fasten your seatbelts as all these components converge to transform that way we drive.
