Electric Vehicles? Towing? Hauling?
There seems to be quite a push lately for zero emission vehicles and electric only vehicles. How on Earth would these ever work for us? You can't go cross country in an electric vehicle in a pra...

I haven't read past the third page posted three days ago so this may have already been said:
The logical solution to the recharge downtime while travelling is to create an integrated infrastructure allowing to quickly and safely replace the vehicles discharged battery pack with a freshly charged pack. You would pull into a 'fueling station', an attendant will remove your pack and install a fully charged pack. This could take a few minutes and even be automated to where no human involvement is needed. The vehicle needs to be designed to allow this.
The problems:
- It needs to be universal for all manufacturers. Not as easy as it sounds once you get past 3-4 models.
- A gas station might fill up 1000 cars per day. That means you would need close to 1000 battery packs per gas station. At 10k-15k per battery pack, that would be 10-15 million in stock.
You could cut the stock a bit fewer if you are charging the spent battery packs but that creates other issues. If they can put 80kwh into a battery pack in 30min would require, around 1350amps @ 120v per battery pack. To top up 1000 packs at 30min each would require around a 28,000 amp service (probably use higher voltage but puts it in perspective how much the station would need). Also, this assumes evenly distributed swaps over a 24hr period. With spiking demand in the morning and evening, likely would be higher.
No swapping battery packs is not reasonable.
Again. Can’t compare gas stations to charge stations. The vast majority (around 95 percent depending on region) of charging is done at night at home in a driveway. There will never be a need for as many DCFC stations as there is for gas stations. That’s one of the reasons people buy EV’s. No more wasting time at gas stations.
