If you have a battery on hand ready to suck down that power in EVs, all you have to do is contact whoever managed such a feat to provide your charging facility with the battery cache. And you don't have to recharge your cache off the grid/solar/wind/whatever at the same rate you charge the cars of waiting customers. You just need space for a big enough pile of batteries. Last I checked gas stations were rather bursty around rush-hours. Worst case the charge rate degrades after exhausting the cache. There will always be lulls between the thundering herds to allow filling it all back up. Is it really all that impossible to imagine? Maybe the gas stations of the future are battery towers.
