Exploring Olympic National Park in a Nissan LEAF

On Veteran's Day last year, I attempted to drive our Nissan LEAF on a day trip to Washington state's Olympic National Park with my two small children. The EV driving was stressful, and we never made it to our destination: Hurricane Ridge.

Fast forward a half year. While reading excerpts from one of my heroes, John Wooden, I came across what Wooden described as "never flinching at failure." (p.18) Wooden described this persistence, "If you are not making some mistakes, you're not doing anything--not trying to make things happen," and later, "act, initiate, and be bold in execution rather than hang back in fear of failure." (p.19)

For those who have plunged themselves into electric vehicle ownership during this early adopter phase, there are really two camps. One, the EV driver who is only comfortable in driving within a tight radius around home and work. The other encompasses the pioneers of the EV movement. These are the EV drivers who are determined to make driving electric work in their lives, and push the envelope to do so. There are failures, yes. If folks are not pushing the envelope--in whatever the endeavor--change...growth...progress will never happen.

Wooden's words worked. I was inspired, and ready to take on the world! So, naturally I started plotting how I could overcome one of my own (EV) failures. I remembered that attempt back in November wherein I nearly stranded my kids and myself at least two times in one day, and failed at reaching our ultimate destination.

Driving from the Seattle area to the Olympic Peninsula in a Nissan LEAF presents some unique challenges. Getting to and from the peninsula was first on my planning agenda. Washington State Ferries, the largest ferry system in the U.S., does not have 24 hour service on the ferry route that I needed to take to get over to Olympic National Park. One of the mistakes I made on my last attempt to the Olympics was to plan the trip with the idea that I just had to make the last ferry of the night. This time, though, I switched my thinking; I planned everything around catching the first ferry run of the morning.

Topping off the charge before driving onto the ferry.

We left home at 5:30am and pulled into a local PCC Natural Market by 6:00. With the ferry departure at 7:10, there was about 45 minutes of Level 2 charging to be had before getting underway again. This "top off" was very important because I was able to make the drive to the town of Port Angeles without stopping for additional charging.

On board the Puyallup, the largest class of ferry in the Washington State Ferry fleet.

The town of Port Angeles really can hold its own as a destination location. It is wedged between the Strait of Juan de Fuca and the base of the Olympic Mountains. The two, or so, hours that we were in Port Angeles were great. It was yet another time that we had an opportunity to be "stuck" in a town that I would have unfortunately driven straight through when our family had an ICE (internal combustion engine) vehicle.

With about a 95% charge, we departed Port Angeles with our sights set on Hurricane Ridge and Mt. Olympus. The 17-mile drive to Hurricane Ridge was from sea-level (literally) to more than 5100'. Using LEAF Spy, an app for Android devices, and my trusty OBD-II bluetooth dongle, I logged data for comparing the expenditure of energy going up the mountain as compared to how much energy was recaptured via regenerative braking on the way back down.


Hurricane Ridge, Olympic National Park

The drive from Port Angeles to Hurricane Ridge consumed 160 "GIDs" of energy. A GID is a Nissan LEAF-specific measurement of battery charge that represents 80 watt hours. After walking around for a while to enjoy the sub-alpine meadows, we loaded back into our LEAF for the return trip down the mountain and eventually home. 

On the decent we regenerated 40 GIDs--just 1/4 of the energy that was used to climb the mountain! I was really surprised that more energy was not recaptured on the 17 mile decent. I suppose, though, that I shouldn't have expected otherwise, as my previous record of downhill power regeneration only netted 24 GIDs on a similarly steep decent from Mt. Baker in Washington state's Cascade Range.

The hills are alive with...blacktail deer!

Our remaining trip home went smoothly, and was almost uneventful. The one hiccup came while charging in the town of Sequim. After plugging into a Level 2 charging station in the alley behind Nikola Broadband, we hoofed it across town to a burger joint. And just after we sat down with said hamburgers, I decided to check the LEAF's charging status via a smartphone app called Carwings. The status update was disheartening, as it showed that the car was plugged in but not charging. After wolfing down our food and trekking back to the car, I was surprised to see that the car was still charging! I think that the issue actually stemmed from the lack of cell phone service in that neck of the woods. The LEAF's onboard communication couldn't even catch the requisite 2G wireless network needed for the Carwings service to work properly. While I was just glad that the car was charging, I couldn't help but think of the irony that proper cell service was not available in the parking lot of a wireless network provider. Go figure.

***

With our trip now completed, I have again returned to the wise words of John Wooden. The kids and I were determined to make our trip to Hurricane Ridge happen. It was a wonderful lesson of perseverance as an EV pioneer. It was a wonderful experience, too, as a father.

A Day in the Life of a Two-LEAF Family

Pushing the range of our Nissan LEAFs into the EV Badlands is one of my most beloved of passions. However, I do have a family. A family with two all-electric Nissan LEAFs. A day in the life of our household is more about cross-town errands than cross-country epics.

With over 50,000 combined miles on our cars in less than two years, it really is the daily grind, not the occasional EVenture, that our EVs do the heavy lifting.

This is what it is like to be an all-EV family on a typical Saturday. Yes, the logistics are different than when we had our ICE (internal combustion engine) vehicles...


A.M. PLANNING

Charging Both EVs to 100%

Perhaps the most important thing that we did to make life manageable with two EVs was to install a second EVSE (electric vehicle supply equipment--aka "charger") in our garage. On weekends, it is especially useful to charge both LEAFs simultaneously to 100% if the day is looking to be a busy one.


YOUR CAR, MY CAR

My wife has her car, the black 2013 LEAF. Mine is the white 2012 LEAF. Yes, she gets the nicer of the two (leather, shiny wheels, yadda yadda yadda), but we end up swapping cars quite often.

The reason for the spousal exchange is that the 2013 LEAF has a 6.6kWh onboard charger, while the 2012 only charges at about 3.6kW per hour. Therefore, if there is any anticipated Level 2 (240v) charging needed during the day, the 2013 LEAF will be driven on that trip.

To the YMCA for Swimming Lessons

Looking ahead to the afternoon, I had an upcoming 90-mile trip and would be Level 2 charging at the halfway point. Those logistics meant that I needed to first take our kids to the Y in my 2012 LEAF and my wife would take her 2013 LEAF the short distance to a Relay For Life event in late morning hours.


Car Swap!

After swimming lessons, the kids and I swapped LEAFs for our afternoon trip to go have some fun. We picked up my stepfather in the black 2013 LEAF and drove about 45 miles to one of his job sites so he could take the little dudes for some joyriding in a 40,000 pound CAT front loader.

BE PREPARED

Aside from having ample charging available at home, it is critically important for us to be able to charge our EVs from various power supplies when EVSE infrastructure is not available. We have a portable EVSE that is capable of charging up to 240v and 20 amps. This equates to a 4.8kWh charge. While it doesn't max out the Level 2 charging capability of our 2013 LEAF, it is still good for about 19 miles of added driving range for every hour of charging.

Guerilla EV Charging!


THE PLEASURE & PAIN

Our typical Saturday of errands and activities had us traveling a combined 135 miles between our two Nissan LEAFs. Clearly there is a bit of "pain" in relying on two sub-100 mile range EVs to completely fulfill transportation duties. For us, though, the pleasures of EV ownership far outweigh the logistical challenges.

The financial savings are remarkable. The 135-mile travel day would have cost $20.25 if we had a medium-sized ICE family sedan. Instead, we paid south of $4.00 for electricity (actually, less than that because 4kWh were charged for free).

The gas vs. electricity comparison of costs is even better when probing a bit deeper into the realities of the two "fuels." Gasoline prices fluctuate. The cost of electricity is stable. Being the typical family that we are, having stability in our monthly budget is very important in getting through each month. Driving electric vehicles takes out one of those budgetary items that always seemed to hammer us with a budget-busting rise in gas prices at the worst of times.

While the fuel savings is our immediate gratification for driving Nissan LEAFs, another "pleasure" that I have come to realize with driving our EVs is actually more of a long-term investment. Our children, ages six and three, are growing up with "energy usage, energy efficiency, and energy costs" as a part of their lexicon.

That is truly what the world needs: A whole generation that has an understanding of the global impact of personal energy usage.
