Leaf Trip Corvallis to Seattle
May 25-28, 2019

The next road trip plan for my Leaf was to go to Seattle (with a stop near Centralia for a gathering at a friend's place) for Memorial weekend, using the lessons learned from the trip to Stanfield.

My charging plan on the way up:

  • Ridgefield
    • 107 miles, but I'll be in Centralia overnight, giving the batteries time to cool down
  • Centralia
    • A bump charge to get me to the gathering and then the hotel I planned to stay at Saturday night, which is near the Tumwater charging station
  • Tumwater
    • Since I'll be at the gathering for several hours, the batteries should have time to cool down enough to do a charge on the way to the hotel, which will then give them overnight to cool down again
  • South Seattle
    • Sunday, having charged the night before, I'll be able to make it all the way to South Seattle Nissan to charge, which will give me enough to run around Seattle the rest of the day. Sunday and Monday evenings, I'll again charge for the next day, if needed (as turned out, I didn't really).

On the way back:

  • Tuesday morning, before I head back, I'll find a 7kW "level 2" charger and charge while calling in to an 11am meeting.
  • Centralia
  • North end of Vancouver (where I205 joins I5)
  • Salem

All of those charges are to 80% as the last 20% is slow and harder on the battery when done as fast charging (50kW).

I ended up following the plan pretty much, except I ended up being able to skip the Salem charge on the way home - basically, if the weather cooperates, it only takes 2 charges to get between Seattle and Corvallis.

The hotel I stayed at in Seattle (4 Points Sheraton) actually had charging stations...but they were Tesla wall chargers, not standard J1772 chargers, so I ended up going back to the South Seattle Nissan dealer and used one of their fast chargers Monday night to get to 90%, and then one of their J1772 chargers to get almost fully charged during my Tuesday meeting.

Although I was actually able to do this trip, without much overheating of the batteries, Nissan still needs to do cooling - if it had been hot out, it would have been a completely different story!


Start at home

 
Off to a good start, with a 100% charge and outside temp in the low-60s. The charging screenshot must be showing the last fast charge I did, as I don't have a 30kW charger at home ;-)

I grabbed lunch at the Country Cafe while charging; the temp gauge shows well below red line, probably thanks to it being cool out.

Centralia - Arrival 1

 
Battery warmed a couple of degrees, but still looking ok... While doing these screenshots, I found that there were more screens than I thought in LeafSpy... The miles in the dash screen are low because I forgot to reset the trip meter for a bit. Several times on the trip :-( Fortunately, Leaf Spy screens show the odometer and I can compute the distance...

Although the battery wasn't all that hot, it still took 40 minutes to go just from 13% to 50%. No idea why the charging power screen went blank...

I was at my friends' place for a little over 5 hours, and the batteries did cool down over 20F, but still a bit warm. And oh look, some previous charging screen came back to the charging screen :-( (I didn't charge to 80% in Centralia...)

Batteries still hot enough that it took almost an hour to charge to 80%... except as I look at that charging screen, it says it's only charging at 30kW, and 20-80%, or 60% of 40kWh works out to 48 minutes. And that's the rate it was charging the first charge, so this is just the AV chargers being a little light on the power...

Not sure how I managed to lose 2% overnight! And the batteries still haven't completely cooled off, being still 20F over ambient...

In the speed graph, you can definitely see the effect of Seattle area traffic ;-) I really love the active cruise control in the Leaf!

South Seattle Nissan - Intermediate 1

 
Now in this charging screen, you can see the effect of battery temperature (or something), as before, the charging power dropped off when the battery got to 70%, and here, it drops off when it gets to about 65%, though the fact that this charger is charging around 40kW may have an effect too.

Since I had some time to kill, waiting for a friend I was going to meet to become available, and the battery wasn't too warm, I let it keep going...

South Seattle Nissan - Departure 1

 
No one was waiting for a charger, I had time to kill, and the battery wasn't heating up, so it ended up going to 98%. There was a definite additional drop in charging power at 90% from the graph though.

South Seattle Nissan - Departure 2

 
I didn't record the arrival stats, as they weren't really relevant - just some local driving - only about 50 miles total. Probably should have captured it for completeness though. Here, I charged up to 90% since I had the time the evening before I was heading back. I had a phone meeting to call into at 11am the next day, and planned to come back here and Level 2 charge to 100% while in that meeting. Charging up tonight gave overnight to cool off, though as it turns out, that wasn't needed. Even so, I didn't want to start off the trip with a fast charge first thing...

The charging power screen clearly didn't record this charging session :-(

It was a bit more of a round trip to the hotel than I thought, hope the meeting is a long one if I want to get to 100% at Level 2 ;-)

Well, the meeting wasn't quite long enough to get to 100%, but close enough... Looks like the Level 2 was charging at 5.5kW, though even it dropped at the end.

Only a 40% charge shouldn't heat things up too much

A half an hour for a 40% charge is about right I guess...

An hour to do 65% (15->80)...is actually about right I suppose. I guess I need to get used to having a larger battery ;-) However this one did take me right up to redline!

Arrival Home

 
It took 4 tries to get the picture showing the remaining miles, as it was blinking and the camera kept catching it when it was off ;-)

I actually made it all the way home on the 80% charge - which really shows the difference weather makes, as when it's coldy and rainy, an 80% charge at Wilsonville will get me home with little more...
