Maybe, but that only really works if you have a battery leasing concept - like e.g. Renault Zoe. Otherwise, you're swapping something you "own" with something that may be of inferior quality. Would you really feel happy having bought a brand new car to find the most expensive component had been replaced with an 8 year old battery just from "filling it up"? What if the previous "owner" had just grounded the car and smashed the battery back into a speed bump or a large stone? Imagine a damaged battery pack caused a fire and destroyed your car... Who would be liable? You? The garage that you last swapped the battery at (and would you even remember where that was)? The previous renter who may had damaged it? The renter who damaged it 2 weeks ago leading to its failure now? The manufacturer for designing in the risk? Are we going to need to pay to staff 24/7 at every battery swap location to inspect the incoming batteries? Then there are the safety risks of having a high voltage connector that has to undergo potentially 10,000 cycles during its lifetime. Any slight misalignment will start to cause arcing and contact degradation, increased resistance and higher risk of fires. I realise that this same argument can be made to high speed charging ports as well, but the connector on the car would have to withstand significantly more vibration. Additionally, the battery is one of the heaviest parts of an EV, so there's a challenge of making something that's easy to remove whilst remaining firmly secure the rest of the time. Such a thing is best supported from underneath, but having top or side loaded batteries would likely cause significant issues with weight distribution. Finally, modern EVs also have contoured batteries to fill the available space in the car, whereas swappable batteries are likely to need to be designed to be interchangeable between models and manufacturers. To me, I'd see it as having too many downsides. High current charging can be done safely if systems are designed well, as well as still retaining the ability to fall back to slow trickle overnight charging which will probably remain the preferred option for most. We already have a standardised plug that can support this, the increased current can be negotiated over the control lines just as is currently done.
