In regards to billing, it wouldn't surprise me if it was a combination of strict regulations/registrations about efficiency and then semi-simple toll roads. If you know how much a given truck consumes and the distance it travels, that might be close enough math to not need more detail. I could also see a potential factor of registered load mass having an effect too, but that should be possible to include.

Germany also already has high electricity prices compared to a lot of the world, but I doubt this would be a rapidly adopted thing that is going to cause a massive price spike
