This stupid idea just wont die.... Because every new gas-tank/gas-station legacy thinker that shows up on the block keeps trying to replicate the gas tank model for EV's when they are totally differenet animals.

(sorry) If he is travelling a distance then he has to swap THEM ALL every time he stops OR he needs to stop TWELVE times as often to swap out12 batteries one at a time. Just stupid. Or he only goes a liittle ways, then why swap anyting at all? What he has done is turned a 120 mile EV into a ten mile EV that can stop evry 10 miles and swap another 10 mile battery. Stupid. Better to have a 120 mile EV and use it for what an EV is designed for, local travel and commuting. Stupid to take it cross country and swap batteries every 10 miles... geeze.. bob > Peri > > ------ Original Message ------ > From: "robert winfield via EV" <[email protected]> > To: "brucedp5" <[email protected]>; "[email protected]" > <[email protected]>; "Electric Vehicle Discussion List" > <[email protected]> > Sent: 01-May-16 8:56:39 AM > Subject: Re: [EVDL] EVLN: ?L3 quick charging or pack swaps, on long EV > trips?
