Just to keep expanding on this model: - batteries would be certified by some authority and batteries could meter their use. This would prevent arguments about getting a bad battery for the service station. Certification would be via controlled pass/fail test equipment on site. service stations would handle the recycling of expired batteries. since you are exchanging batteries, the cost of new batteries can be amortized over the life of the battery. The hardest parts would be 1) to get car companies to standardize on a small set of battery types. and 2) design a battery compartment that could be both easily accessed for swapping, and securely locked at other times.

Why are we not looking at making a standard for a swappable battery? You could then pull into the equivalent of the gas station and swap your near dead battery for a freshly charged one. This fixes 2 problems. 1. range anxiety, I don't want to get stuck waiting 2-4 hours for a charge while I am doing some errands on my way home from work. with a battery swap this would only take 5 minutes 2. sticker shock in a few years when the batteries need replaced and their cost are not being subsidized by the government. Since I would be swapping batteries, battery replacement would be part of the "gas station's" business model.

Someone may want to hack you innocuous account so they can post something: -- libelous -- embarrising -- obnoxiious -- illegal -- covertly embedded in the message ... and you will get the blame for it. trustno1
