The advancements in battery tech are obviously great news but I still have no idea how you’d power a “traditional” charging station (with several terminals) for EVs.
There’s plenty of time to find a solution to that before today’s experimental battery tech becomes ubiquitous in cars but power generation and infrastructure seems like it’ll be the bottleneck. I haven’t done the math or anything but it just seems like 5m charging of more than one or two cars at once would strain the grid that exists today.
There are charging stations with 40 chargers delivering +200kW each, they’re powered by HV lines directly to transformers located at the charging stations. But most (all?) BEVs are only near max charging power for a fairly short period of time, and full occupation is also not seen very often. These large stations (and smaller too) are managed by load sharing, so in the theoretical case that 40 cars arrive exactly at the same time with perfectly prepared battery temperature and SoC and all connect at exactly the same time, they will just be capped by the chargers so the station doesn’t exceed available power spec.
