it is my understanding that recharge rate for lead-acid batteries is<br>largely limited<br>by cable size, and that practical quick-charge stations have been<br>built which charge<br>a stationary back-up pack, which is connected to an equivalent-voltage pack in

Skipping further explanation of the propane game's economics we go back to EV power packs.
<br><br>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 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.
