When kilowatts of power are added to the battery over a period of time, that is adding kW's per time, kW/hour.
No! It's kW over a period of time --> kilowatts times hours --> kilowatt-hours (it's a dash, not a minus). kW * h --> kWh
"kW/hour" makes no sense. / denotes division (exactly like how you write fractions like 1/2, 1/3, 1/4) or per. kilowatts per hour makes no sense in this context.
Back to fractions: 1/2 = 1 divided by 2 --> 0.5
Charge at 25 kW * 1 hour --> 25 kWh was dispensed.
25 kW * 2 hours --> 50 kWh
50 kWh / 2h --> 25 kW
So, if I draw 1 kW from a battery that includes 62 kWh, the battery will be depleted in 62 hours.
Yes. 62 kWh / 1 kW = 62 hours <-- notice in this case kW / kW cancels out, leaving you h.
62 kWh / 2 kW = 31 hours
The units are not the issue here. Arguing about units is a red herring.
They are when you don't know what you're talking about and keep interjecting nonsensical combinations of units like kW/hour.
The main point stands that the Nissan's Leaf's claim of charging at 100 kW per hour is not achievable.
Again, you used the wrong units. Charging rate is measured in kW.
kW per hour could make sense if you're talking about the acceleration of power (e.g. the megawatt power plant example I gave earlier and how long it takes to ramp up to 1 megawatt output).
https://web.archive.org/web/2017032...files/documents/686294116/DemandEducation.pdf explains demand charges but you can can look at slides 6 and 7.
https://www.solarquotes.com.au/blog/kw-and-kwh-what-is-the-difference/ points out:
"A kilowatt/hour is a nonsensical unit in most contexts. If you find yourself using this unit, double-check what you really mean, which is probably kilowatt-hour. Kilowatt/hour means kilowatts per hour. Kilowatt is a measure of power (units: Joules per second ), so you are really saying joules per second per second, or joules per second squared. Which would be a measure of how quickly power is increasing. An acceleration of power if you like. There are very few circumstances where that is a relevant measure. Especially when talking about solar or batteries. Lots of people get kilowatts/hour confused with kWh. Please don’t let it be you. 99% of the time, you’ll mean kWh."
I've not seen any official written statement or specs from Nissan claiming 100 kW charging rate on current or previous Leafs.

The blog at the above, as can be seen in the tables reads the 100 kW mention as a claim of a charging rate. This is how every other manufacturer interprets the value when stated in a manual and how every consumer interprets it as well.
I've never heard of this page or blog before. It doesn't look like any official Nissan site or marketing nor technical material.
It is glaringly obvious that consumers and consumer blogs are disappointed by Nissan's claims and actual performance. I am not sure why there are members on this board that keep on countering an obvious issue.
Glaringly obvious? I'm not that active here much these days since I no longer have a Leaf but its is certainly not common for folks here and Leaf FB groups to come in here claiming that Nissan has asserted Leaf can charge at 100 kW and then complaining they don't hit it. You're one of the few or only one.
Of bigger concern is that there aren't many >50 or >62.5 kW CHAdeMO chargers in the US. Sometimes, for whatever reason, "50 kW" CHAdeMO EA chargers have their cap lifted and people can achieve 70ish kW or almost 70 kW like
https://insideevs.com/news/495913/nissan-leaf-dc-fast-charging-curve/. I can't think of anyone reporting even 80 kW on a Leaf Plus. It's usually a little less, at best.
The next concern is that multiple DC FCs in a day will result in rapidgate and significant slowing of DC FCing to protect the battery since the pack has no cooling other than passive air cooling.
I haven't watched all of
but have skipped to points where he charges. For example, at 22:30, his charging rate is down to 25ish kW because his battery is getting roasted. The highest temp sensor value is 47.7 C and lowest is 41.9 C. 41.9 C = 107 F. 47.7 C = almost 118 F.
He did it again in winter with slightly better results:
(skip to 23:10). The better (14 hour, 10 minute) result from the winter test is near the bottom of the graph at
