An autonomous vehicle concept for mobile charging envisions self-driving units equipped with powerful charging systems. These vehicles would navigate urban areas to locate and recharge electric vehicles on demand, extending range and convenience for EV owners. Integrated with app-based scheduling, they could autonomously prioritize high-demand locations and move to under-served areas, minimizing charging wait times. The Polaris concept enhances EV infrastructure, reduces reliance on stationary charging stations, and provides scalable, flexible charging solutions as EV adoption increases.
