Sorry, If I was not clear, i meant from my phone at distance, so not in bluetooth distance. Good point regarding the car needing to be on, though other metrics are available via the connect application.

A couple other quick observations from the trip.

1. Call acceleration from 60 - 80 was very strong (even at high battery temp). What an improvement from the Gen one leaf, which I though wasn't too bad.

2. The car rolls very well. When clicking into neutral, the rolling resistance seemed pretty low. It could be I just forgot what my old leaf felt like new, but it seems better.

3. The 0 power mapping in the accelerator is a bit wider then before, making it easier to roll the car.

4. I was surprised pro pilot would let you turn it on single lane country roads (no divider with oncoming traffic).

5. Wife is convinced now that the cargo area is larger then the 13 Leaf. Bags that didn't fit in the old car, fit nicely in the new one. Kids also report more comfort in the back (all 3; aged 17, 15, and 10).

I have yet to take the car to low battery. Does someone with Spy know how many GIDs/kWh's are left at that alarm with the plus?

It seems to require only a good, solid line on the right shoulder.

Thank you for the point. We left with Battery at midpoint from Chicago. It was one notch above midpoint as we left from Iowa City and 70% in way to first high temp bar as we left Ames.

The Chademo session warmed the battery to the the first high temp mark on the gauge. It didn’t seem to impact charging time at Chademo as we it seemed to stay at the 53KW speed for most of the charge. I assumed the drop to 20 KW was because we were approaching 90% Charge.

The ride home was in upper 80s. We used air most of the way home. Battery stayed at the high temp marker for the entire ride home.

Sorry, didn’t have spy with me, so don’t have the actual temps, just the gauge.

Guessing the higher temp slightly reduced efficiency on last leg, but at 70-72 mph I can’t complain about still getting near 4 miles per kWh.
This is critical. How did you determine charging speed? Dash or station?

Charge "likely" didn't go from 53 to 20 KW in a step (suddenly) so it would have ramped down. What is highest SOC you remember seeing when charging over 50 KW?

Finally; others have said this is bad but I contend the damage was minimal. On my 30 kwh LEAF, it charged at full speed to 80% SOC so I usually charged to a few minutes past the knee generally shutting down charge when rate dropped below 40 KW. Since most of it was work time, camping was rarely an option. I saw 125º+ temps all the time but my pack showed no degradation. Granted a short stint (14 months, 30,000 miles) but comparing the two separately (time with no regard to distance and vice versa) I was well beyond the curve for others in MY AREA.

Dave,

Its a good question, and here is the data I have (pieced together). We plugged into the Chademo at Geneseo at 6:44PM. As I had a free session from EA, I have the phone log in which they started the session for my from. As it was a free session, it did not show up in my charge history in the EA application.

We started at 16-17% on the dash. We watched it for about 2-3 minutes (it was at about 20%). The EA screen and the car both reflected the 53KW charge rate, so assumed it was accurate.

We then went to dinner across the street. I was checking my connect app every 3-4 minutes to ensure the charging continued. With each refresh it seemed to continue to go up 2% per minute, which seemed in line with my expectations at that rate. It was in the upper 70% when our meal came, so at that point stopped checking, as I only needed about 75% to confidently get back (161 miles to home at that point).

After we paid, we returned to the car, it was at 87% and showing the 20KW rate. I don't know how long it was at that rate. It took 5 minutes to get to 90%, which at that point I unplugged as we were now high enough I could drive without caring about efficiency. (the 60 - 80 acceleration curve on the car is quite crisp!).

The car was on the charger for just over an hour, as we got on the road at 8PM (65 or so minutes). I bought a coffee after the charge before getting on the road.

Its very possible it stepped down around 70% or 75% charge, as in the last 20 minutes (between getting food and paying) we only gained about 12% or so, which would imply a slower rate then 53KW.

% on dash are not completely linear, so this requires some salt.
6:44 - 7:25 17% - 75% (so ~36kWh which is about right as the timings are not exact)
7:25 - 7:52ish 75% - 90% ( ~9kWh, so a rate of 20KW or so average, which suggests the step down).

Sorry, I don't have anything more specific.

There is a german video showing an e+ on 2 back to back 500KM travel days using Chademo. Day 2 the heat limitations slowed him down.

I didn't have an issue on my trip, but just had the 1 Chademo session. If I needed to do another Chademo session, I think it would likely been at the slower rate.

No in Chicago, this is a 2 month issue, as outside of July and August, temperatures are rarely consistantly above 85 degrees. But I would think harder about choosing the Leaf if I lived in Phoenix or Palm Springs.

Beside air across bottom of the car, is there any other cooling for the battery? I do wish we had at least the AC cooling routed to the battery like the eNV-200s. That could at least extend the faster charge cycles, even if you were chewing up 3KW of the charge as you recieved it.

For sub 300-400 mile days, its a non issue, but I will think carefully before trying a trip to Denver/Pueblo in terms of battery temp.

One more item on the wish list. Super-Eco mode, which has even a broader accelerator mapping. On the highway, its very hard to keep a consistent power output (allowing for variations in speed).

Because the bigger battery eats up what air space there was in earlier Leafs, you don't really even have that. The ePlus and even the 40kwh Leaf rely on heat conduction and radiation rather than passive air cooling. I assume that the bottom aero cover is still plastic, so it tends to insulate the pack more than conduct heat to cool it...

Leftie,

That explains why I saw no cooling on this past trip when we were in the middle of a downpour. I was hoping to take a smidge off of the battery heat with the rain.

It should be good in winter though, as we will cherish every retained degree of battery temp in January. Chademo also becomes a great range extender as moving the battery from 0 to 10C does wonders for range.

I had to pick up my registration from the dealer (it takes a long time in IL) yesterday and asked him about Leaf sales. He mentioned that they were doing well now and picking up. He said specifically now that that gas tax doubled in IL this month, they had received more interest.

My suggestion to Nissan is to have add showing off the utility of the car over EV-magic, as they are just short of the Kia/Tesla posted ranges. thinking something along the lines of a Tesla 3, Niro, Kona, and Leaf all parked next to each other trying to put something large in the trunk, and only the Leaf being able to manage. (we have put a ping pong table, costco 6' non foldable table, and other things usually we relegate to a minivan in the back.) The Leaf owner can even offer to help transport a few items for the other drivers to be kind (as being kind is an attribute of a Leaf driver).

There was a similar demo in the UK with the Kona vs. the Leaf.

Anyone notice the route planner on the Nissan Connect app gives you elevation mapping. Would t use it to plan a trip alone, but to see the elevation is a nice plus as plugshare doesn’t have it in their mobile version.

Dave,

I just looked at the time stamps of the texts I sent my wife while waiting for the car to charge last weekend to get more exact timing. It took 43 minutes (+-30 seconds) for the car to go from 16% to about 78%. That comes out pretty close to exactly 53KW rate. So the slow down happened at that percent. What I don’t know is at what point the battery hit the high temp marker in the charge process.

The German video suggests that the temp limitation still kicks in.
