it is my understanding that recharge rate for lead-acid batteries is largely limited by cable size, and that practical quick-charge stations have been built which charge a stationary back-up pack, which is connected to an equivalent-voltage pack in the hobbyist's wheels, allowing a rapid recharge as the packs equalize. Useful if you're delivering pizza in an EV or something like that.
yawn
an ev fueling station obviously has to have some kind of local store and pull a leveled load from the grid.
Actually - there are scenarios where the charge method is akin to the "Blue Rhino" exchange cages for propane grill bottles. That being explained in summary as -the customer turns in an empty gas bottle and gets a filled one for a competitive price with a traditional bottle refill station. Skipping further explanation of the propane game's economics we go back to EV power packs.
Think of a standard "Robowash" lane. Same guide rails etc but a floor hatch akin to a quick lube bay lurks awaiting orders to swap power bricks. SO the user experience is comparable to a car wash replacing liquid fuel filling pumps etc. Where does this connect back to previous thread topical? Ok more OOTB time.
The Out Of The Box application is where those racks of CHARGED energy modules are tappable for grid floated inverters. Further consider EVERY home EV as one element of a distributed grid peak shaving system. The dividends come from software setting the Where and When one charges or sells surplus energy. Time of use meters for paying all parties properly already are deployed in many areas.
OF course the software gluing all this together needs to be Linux
