The issue here is that EVs tend to be charged when the sun is down. When sun is up you tend to be at work or driving. The surplus power is coming from solar.

- thelastgallon 2mo agoEVs are parked 95% of the time. If it's parked, it can be charged. Work places also have electricity.
- KaiserPro 2mo agobut you're assuming that work provides parking. Its not a given, plus whats in it for the drivers? plug my car in, it might be full, it might be empty, either way its racking up the charge cycles for no direct benefit for me. Batteries on a house makes a better sell for customers, and also targets the problem of both over supply and over consumption at source.
- organsnyder 2mo agoWorkplaces (and other locations) could offer free/reduced-cost charging, with the caveat that V2L is required. They could guarantee that the vehicle will be at a certain charge level at a designated time, and that the vehicle will never go below a threshold (in case an unanticipated trip is required).
- cube00 2mo ago>Work places also have electricity. Only households can access the free electricity window. If you're not on a free plan you can get reduced rates during the solar peak window but business accounts aren't allowed to access those either.

- bad_haircut72 2mo agosurely its possible to invent a "plug in road" system, then cars could charge (at least on highways etc) even when driving. I had this thought ages back when EVs first came out, to tackle the problem of long charge times when doing cross country road trips.
- squigz 2mo agoI imagine this would make road repair even more common, intensive, and disruptive than it already is?

- organsnyder 2mo agoIt's much more difficult when the ownership of the vehicles isn't centralized.

- rswail 2mo agoYou could combine the best of dodgem cars with drone nets by encasing all the highways in electrified wiring. Some people drive as if they're in dodgem cars as it is.
