I've been trying to do a back of the envelope cost for an on-site Megacharger and I realized I don't know enough about electrical infrastructure. Tesla has announced its first V3 and said in 2017 that the Tesla Semi could go anywhere in the US. The rough number talked about on the forums is 1MW per Semi stall charging. This got me thinking, how much land and how much power infrastructure would be required for a "steady" stream of semis. I am used to "Low Voltage" being 5V but apparently when talking power distribution, it's less than 1KV. There are (apparently) all sorts of tradeoffs for infrastructure, equipment, and space requirements between Low Voltage(LV) and Medium Voltage(MV). Additionally, the cables are water cooled. Is that an additional 1, 10, 20, 20+kW per Semi station? If we're talking 0 to 5 Semis charging at a time, what kind of setbacks and electrical infrastructure would be needed? Is there some point where a step up (literally or figuratively) in infrastructure would be needed? Thank you for your time. I fully acknowledge that this thread does not consider the cost of aggregate and foundation, zoning issues, permitting, rebates, credits, Energy Storage Systems, and more.
