Can you imagine if we did something like this? https://www.autoblog.com/2018/04/12/china-smart-solar-road-ev-charging/
Electric cars would take over from just about everything.
This is putting the cart before the horse, or the road before the car as it were.
The only way that charging the vehicle from the road would be worthwhile to anyone who actually enjoys driving their car would be some sort of wireless charging system. The impracticality of a system like that with our current state of technology is immense.
Even wirelessly charging a cell phone in 2019 brings a significantly slower charging speed. While that has, and is still, improving year on year, charging a static cell phone battery wirelessly is still a significant challenge, let alone a free moving motor vehicle.
Assuming electric car companies in China manage to get the technology to work correctly and reliably, it wouldn't likely in this day and age, have a positive effect on the battery. 120V connection to a Tesla only nets you 4 miles per hour. I can't imagine wireless charging off a road, while the car is moving, would even be able to manage that much.
Electric calls will take off in a very major way, as soon as battery technology matures significantly. There wont be any reason to own an ICE when a car battery is able to charge from 0-full in 5 to 10 minutes. With all of the research going on, hopefully that is coming very soon.
