I have asked this question before but I can't remember what the answer was.. Not being 100% familiar with how vfrb's work technically (general understanding only), I get that fast charging isn't possible, and energy density might make the batteries too large for EV's, but if a vanadium battery was depleted of energy, could you pump positively charged electrolye into it?
e.g. you take your car to a 'fill-up' joint, and essentially do the same as you do with fuel. Plug in a hose and it exchanges positively charged electrolyte for depleted electrolyte from your car... So you are not techincally 'charging' your battery, but exchanging the power from a larger stationary 'already charged' battery...
I could be totally off the mark with how these things even work and this may be the dumbest question ever asked, but i'm prepared to look dumb for a good technical answer.. Also this is not a comment on whether vanadium could be used to power cars (I think there will always be better options for this application), more a question of is this type of energy exchange even possible?
