Electric vehicle charging: what challenges?

This data-file tabulates the greatest challenges for charging electric vehicles, based on the recent patent literature, looking across fifty patents filed by leading companies.

Our top three conclusions are that EV charging will require complex algorithms to ensure grid stability, creating an opportunity for big data companies; vehicle-manufacturers are concerned about balancing the convenience of EV charging with the investment costs of charging networks; while interestingly, increasing speed of charging is not a primary focus.

Our conclusions are typed up in the data-file, plus the full back-up of patents from large OEMs, EV-charging specialists, capital goods companies that make components and tech giants, working on optimization algorithms.
