With how many passengers ? I think they should provide a table that shows DCFC speeds by battery temperature but between you and me, how useful would that be to Joe consumer ? Or to you, for that matter ?
You are correct. My frustration is that even at mild temperatures the Leaf is throttling down the charge speed and I am sure that the average Joe consumer would be pissed about this. This did not happen to the 2016 Leaf.
Here is another test I did yesterday:
So outside temperatures were mild 25C. We took a trip to KOP Mall wich is a light ride for the 40 kWh leaf. My battery temp stayed all day smack in the middle. (i don't have the Leaf Spy adapter yet so just bear with me).
On my way back i stopped at the last plaza on the Turnpike before my exit to test the charge. I was at 26% at the time enough to get me home. Right of the bat the charge got throttled down to 32kW. No Idea why. I had done nothing weird. i drove under speed limit. The car had been parked underground at the Mall the whole time.
I have NCTC so I said what the heck lets put some free juice... So I left it for about 20 mins or so.
The temp got up 2 notches very short after initiating charge 5-10 mins. (there are 4 stages/notches between middle and first red line) So the temp was at what i would call 3/4 during charge and the power stayed at 32kW all the time. After 20 min, the charge got up to 64% so I said let's try something new:
So I stopped charging unplugged and then started a fresh new charge. Guess what? the new charge was throttled down to 22kW. Let's be clear: It was 32 when I unplugged and the charge level was way before it throttles down for being full.
So the computer saw the temp was high at 3/4 and decided to throttle me down even though, had I left it alone, it would have continued at 32.
In other words the charge power is determined at the beginning of the charge based on the temp at that moment and kept constant throughout the charge independent of temp rise. Only the charge level throttles down the power during a charge.
