The EV refueling problem seems like an easy one to solve: create industry standard, modular, and replaceable battery cells.
Refueling is done by swapping-out low charge battery cells for fully-charged battery cells. If designed properly, the swapping could be done quickly and easily, making the overall refueling of an EV vehicle at least as fast as filling a gas tank.
The cost of refueling would include the price of the charge itself plus some moderate fee to amortize the cost of replacing cells that go bad, which likely would still be cheaper than the cost of gasoline.
The refueling station itself could either constantly charge the battery cells on hand or choose to keep a larger number of backup cells and charge exclusively during periods of cheaper electricity - whichever ends up being more cost effective.
- mattmanser 2y agoI don't think this is true, admittedly with me not knowing that nuch about ev car batteries. But I believe an EV car battery weighs about 1/2 ton for 200-300 mile range or whatever it is today. Say you make cells that a less than average person could pick them up, say 1kg, The number required to change, 500, would makes it clear it's not a trivial problem at all.
- dagmx 2y agoMost definitely not easy to solve because battery packs are a structural component of the car with variances in how they are charged/cooled etc, and as such would also then require standardized electrical+cooling and standardized body shapes. You’d also need to store these fairly large objects in unused but high enough numbers for the subset of people who would opt for that instead of just waiting a little bit longer for a charge.
