Engineering360: "Battery swapping service to make EVs cheaper"

No, I don't think EVs will replace ICEs. Hydrogen powered fuel cells will replace EVs and ICEs. The fuel cell has all the advantages of the ICE without the pollution. Mainly, it can be refueled in about the same time as an ICE. The economical production of the fuel cell is already in place. The only real obstacle to fuel cell powered cars now is the cost of hydrogen. There's a lot of private research going into solving that problem. Once the price of hydrogen gets low enough to make the fuel cell powered vehicle competitive, there will be the biggest change in transportation since changing from horse drawn carriages to automobiles!

With battery change stations a change can be made quickly, but the batteries have to be recharged. How long does that take; guess 5 hours considering quickness versus battery lifetime. Thus the change station's inventory will have to be however many batteries they will change in 5 hours plus a safety number because the change rate will not be constant.

Also, consider that some drivers will claim they got an inferior battery!

As for selling EVs $10000 cheaper, that means the EV is useless until the purchaser invests in a battery--the savings is non-existent.

No where does it state the actual time to swap a battery out and in into one of these EVs. I want to see the actual time taken from pulling up at the swap station to driving away with a fully charged, quality guaranteed battery pack.

If no tests have been performed on the actual time taken for the swap then it is just another load of show food, waffle!

By the WAG method: 15 to 30 minutes.
