Forgive me, but afaik you can't really run truly high voltage AC lines underground - the main issues are electrical arcing and capacitive ground coupling, which leads to losses. HVDC has its own issues as well, mostly having to do with electrolysis, and it being crazy dangerous.
I mean, you can, but it's going to be very expensive.
By the way, have there been studies of what a 100% EV society's infrastructure look like, especially in countries without access to cheap and abundant renewables? I feel it's going to be quite a challenge, and would only make sense economically as part of a broader reindustrialization effor (which for the record, I support).
As for batteries, I think solar/wind require those anyway, and if a solar farm is backed by a huge battery bank, those can probably supply these ludicrous kWs these chargers would need, but transmission is going to be a challenge.
I would love to read something that would go in depth on how we would support a renewable based grid that also supports powerful fast chargers, as this I feel this needs to be a part of a society-level project, and I'm growing tired of these 'China's building better electric chargers!!!'-style alarmist articles.
- atoav 7mo agoYeah but I am not talking about high voltage AC under the ground, the bigger problem IMO is literally the last few kilometers to peoples houses. Everything before that costs money as well, but is usually better upgradable by design (at least over here in Europe).
