This is important because some won't do as well in temperature extremes and may have different optimal charging conditions. Some may take longer to charge as well. That is a lot of information people should know. On a diesel truck, the gas cap says "diesel fuel only", and people still mess that up. Having different battery types will probably accelerate wear because people won't know how to properly use and care for them.
You mention that nickel batteries don't charge fast. What if someone routinely hooked up their car to a Tesla supercharger? Would there be built in protection?

Limiting everyone to just one choice isn't wise. It has never worked in the automotive industry, and it can lead to an entire line of technology failing due to lack of improvement.
Imagine if in the early days of the automobile people decided not to try different technologies because they weren't the absolute best for their time period? Hitler told Ferdinand Porsche that he wanted him to develop a 4WD, front engine, water cooled diesel car as the original "Kraft durch Freude" car. Was that the absolute best tech at that time? Sounds like it to me. Would it have sold like the VW Beetle ended up selling? Doubt it! Is lithium ion the kind of tech that will really catch on? Could something else do better? We won't know unless someone tries.
What' if we had thrown automatic transmissions, EFI systems and EGR valves out the window long ago? Many people sure wanted to, and lots of those did on their own vehicles. But look how things have improved now! Sure, something like NiMH might not seem to be the best option. But what about in the long run?
Some things end up working for some and others for others. Diesel is great for comercial vehicles, gasoline for personal vehicles. How can we be sure that lithium ion is the best option for everyone?
A big problem with EV sales isn't that buyer's are confused with too many options, but just the oposite; that there aren't enough options.
I didn't say that NiMH don't charge fast. I think they charge really fast. 50% charge in 15 minutes isn't slow IMO. That could be 80% in 30 minutes or less.
