This language use suggests Nissan tries to avoid another rapidgate scandal for overpromising.
All they say is that battery could charge at 100kW, but only in very specific circumstances:
not cold (at least 5 bars), not hot (no more than likely 8 bars), when state of charge is
getting close to peak pack voltage (of around 395V) and cell temperatures have been equalized as
some cell cores are cooled much faster than others. Therefore peak 250A (is what conductors will handle).
And due to no cooling (looking at pack production video, there are no fans, no cooling units)
"peak" can be achieved only once per trip (almost the same story with 40kWh overheat).
In most scenarios users are guaranteed to get 70kW charging rate as MAXIMUM expected charging speed
for normal weather (no more than 25*C) (that means below 390V it will be lower, like 65kW and after 395V has been
reached, rate will drop significantly - normal charging speed tapering due to maximum cell voltage limit).
70kW is likely equilibrium point where charging and driving at medium speed in medium weather will
cool down the pack enough for next 180A peak charge rate (70kW).
Like I said, do not EXPECT any faster charging than 70-80kW. The fact that it can do more in ideal conditions
once is something nobody should rely on for any longer trip.
30 minutes of charging, 35kW of capacity. That gives 2 hours of driving. Again, 30 minutes of charging, 2 hours of driving.
If Leaf e+ had refrigerant cooling unit, it could be able to charge at slightly higher speed than 70kW, maybe 80kW.
But only slightly, as I was also expecting air passages between cells. No. They are extremely heavily packed. Thermal
equalization will take whole night before next 100kW peak can be accepted.
Therefore... it didn't make sense to push refrigerant system into the pack. It would hardly help. I totally agree with engineers.
Looking at my two year old signature, Leaf e+ still gets "Medium range EV" badge from me.
At that time even 40kWh Leaf was totally unheard of.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW
