With all due respect, I can't think of a discussion on this forum where I could not infer what poster meant even if s/he got units mixed up, it's usually clear from the context.
I feel the same way, I've always felt that I know exactly what people mean regardless of using kW or kWh or KwH or KWh or anything else, same as using charger instead of EVSE.
Everyone makes mistakes so even if they know they might slip up. Go easy on people, who cares if you know what they mean let it slide. If you honestly don't know what they mean and are confused then I would say that your grasp of understanding how communication works is worse than their grasp of units of measurement and BEV terms.
As you can see below, some people even make mistakes while giving people s*#! for making mistakes. How many people actually think that below EVDRIVER was using "buy" to represent a purchase or just meant to use by?

Yep, you seem to be confused by KW vs kWh.
kWh is a battery
KW is a charger
no one is talking about a 100 kw battery they are talking about a 100KW charger for a 60 kWh battery.
You'll have to get used to the KW vs kWh before you can keep up with a discussion like this.
No, I know quite a bit, but I am not writing a technical paper here. I feel very informal in a car forum, and would hope that people understand what I mean when I talk about a 24KW battery....
With 150 posts here you should know the difference
buy now on a simple concept, you can measure power output of a pack that way but not capacity and the LEAF has more than 24kw output. Just as watts and kw are not the same, there is a big difference in your terms.
Now back to the main topic.
I've always said that it's pointless to provide more battery than one needs, and I think that the race to cheaper 200 mile cars is not as important as much cheaper 120 mile cars (EPA range) for say under $20k. However there are a few other advantages of having 60kWh plus batteries. For people that are going to rely on using quick charge for highway trips they have to think of the highway range after a quick charge to be from 80% unless they want to wait a long time for that extra little bit. For winter use it's added security that the car can do what you need when you need it with heat and possible detours. If a super aero super light car can get 200 miles with 40kWh of battery it will probably take about the same energy to heat it as a car that gets 200 miles with 60kWh of battery so the drop in winter range could be more severe in the smaller battery car.
All those are from my observations as a current BEV driver, but it's more important to offer non current BEV drivers what they want to transition than it is to please current owners. I strongly suspect that once BEVs get a foot hold in the market most cars will max out with a 40-50kWh or so battery.
