Day 2 (12/25/12) – Forest Park, Rain and an Unintentional Tank Circuit?

Some days just suck for traveling and Day 2 definitely was one of those days.  When we walked out of the hotel it was raining steadily and just above freezing.  It’s that wet cold that just chills you down to the bone.

We made the best of it and explored just a little bit more of Portland by taking a rainy hike in Forest Park before heading south out of Portland on our multi-day trek to San Francisco.

Just before heading out we decided to try out one more charging network with the S, this time ChargePoint. I expected that it, like the others, would just take a swipe of their card and plug into the S with the handy J1772 adapter; however, this we quickly received an error message informing us that we needed to call Chargepoint. Being Christmas Day, I didn’t expect anyone to answer the phone, but I was quickly proven wrong as my phone call was answered and a simple issue of a zip code miss match was cleared up. The issue turned out to have nothing to do with the S.

We headed south on I-5. Between the my driving after the mountainous terrain in Forest Park, we quickly found ourselves ready for a charge by the time we were at Corvallis. Fortunately, the rain stopped for a few moments as we pulled into the local RV park, and I decided it was the best time to test out my custom designed EVSE (Technical details in the Multi-Input EVSE blog post).

I started slowly as this was the first time attempting to plug my EVSE into a Model S. I had only a week before brought my system up to the point that it was ready to charge a car. I had a close friend who was willing to let me plug into their Leaf and therefore, only knew it worked with that model. I was very pleased to have the Model S immediately communicate with my EVSE and initiate a charge. I slowly increased the current eventually charging at 50 Amps and 240 Volts! :)

By this point the rain had started again and it was about 35 degrees out so we decided that we would take a break from the RV park. We ventured to Corvallis for a warm meal and according to Plugshare, a free J1772 system to plug into just a block away. My EVSE was quickly unplugged and off we went to dinner. Just as Plugshare had shown, a free J1772 (240V 30A) was available, and we walked a block to a Chinese restaurant for Christmas dinner.

After dinner, back to the RV park we went where I began phase two of my test plan by plugging into two 14-50R’s at the same time allowing for a charge up to 80A/240 Volts. This would essentially reduce an eight hour charge time at the RV parks down to four. I plugged the power in and nothing… Out came the tools and I quickly determined that power was entering my box just fine, but it wasn’t powering up. Just as I discovered that my fuse had blown, the rain started again and it was starting to get dark. It was quickly decided that retreat was the better part of valor in this case and we watched Dumb and Dumber in the car while waiting for to charge using the standard Tesla EVSE.

Once charged up enough to make it to our next planned destination in Ashland, OR, we headed south. The weather took a turn for the worse and reports showed that the mountain passes were experiencing blizzard conditions.  We quickly found (again, using Plugshare) a nearby hotel that had an AeroVironment charging station in its parking lot.  I was skeptical. It was Christmas night and my attempts to acquire a fob to use at the charging stations had been rejected because I do not live in OR. I was promised by AeroVironment that their 24/7 phone number really was 24/7.  Sure enough, at almost midnight on Christmas night they answered the phone and after a short discussion on why I would want to enable the L2 charger when there was a faster L3 sitting there ready, the free charge was started!

To bed we went as I began to ponder the problem that occurred when I unplugged my EVSE as well as its solution.


Day 3 — From Charger Woes to Charger Boon

My body still on East Coast time, I happened to wake up a bit before 6am today.  Remembering a story from Steve and Jesse, I decided that I should check in on the car to see how charging was going.  It was a good thing that I did, as it wasn’t.  Somewhere a few hours before the charger had decided to stop supplying power to the car :( .  A quick call to AeroVironment (who I must say was there to answer the phone again, this time the day after Christmas at 5 something AM) and they restarted a new charge session.  Perhaps there is a time limit on charge sessions?

In the end, the delay in charging was a secondary delay for the day.  A quick check of the weather ahead showed a snowstorm still raging in the mountain passes ahead and wouldn’t be lifting for a few hours, and with the Summer only performance tires still on the car, I decided it was time to go back to bed.

A number hours later, and a minor modification to my EVSE identified, which was easy to work through in the warmth of the hotel room, and we were packed and ready to go.  At this point we had been moving bags in and out of the S for three days, mostly in rain, and I have to give the designers of the rear hatch a shout out.  Every time I opened the hatch, the water covering it was perfectly funneled to the sides and off into channels below waiting to whisk it to the ground never onto my stuff below.

We made it through the passes easily, black pavement being cleared ahead of us by front loaders.  After making it through, and into California we found our next RV park, who were happy to have an EV charge there and didn’t mind us plugging into two 50A outlets.  This time the EVSE came up without issue and after a number of final checks I gave it the command to combine input sources and feed them to the S.  Almost instantly the relays clicked and the S ramped charging up to 80A at just over 240 Volts.  Charging was going by so quickly that we went ahead and charged all the way up to a full Range charge and determined that we should just be able to make it to the Superchargers at Folsom.  The drive was smooth, but as I’m still dialing in my ability to arrive at my destination with the margin I would like, the 10 miles margin I had calculated slowly slipped away.  I finally arrived at Folsom with 3 miles left, and somehow managed to bring it down to 1 as I slowly hunted for the Superchargers.

When we did find them, using them could not have been easier.  We pulled in similar to how you pull up to a gas pump, walk over to the cable is easier to handle than a gas pump handle, push the button on the handle which causes the battery door S to open, and you plug in the Supercharger cable to the S.  I took a video of this, but as it was taken in the middle of the night I’ll have to clean it up some before I post it.

Just about this time, the local security guard, who had apparently been watching a suspicious car slowly meander it’s way around the closed outlet center, came over to see why we were there.  He had never seen an S use the Superchargers before and by the time we finished showing him and with the follow-on discussion, the car had already charged up to 65 miles.  Charging progressed at almost 300 miles for quite a few minutes until it slowed it’s charge rate down (to protect the batteries).  We only charged to ~180 miles, as that was plenty to be able to make it over to Fremont, and onto Menlo Park.

Having filled up heartily we zipped over to a hotel that split the difference between Folsom and Fremont, and called it a night.

Today was quite a day.  We went from charging on the generally available J1772 Charger at 19 miles/hr to charging on my custom EVSE at 65 miles/hr to charging on a Supercharger at almost 300 miles/hr!  What a day!

Day 4 (12/27/12) – Winter Solstice Journey to Salvation Cont’d

Jeremy Collins is quoted as saying “Sometimes the best journeys aren’t necessarily from east to west, but from heart to head. Between them we find our voice.” As Peter and I began the forth day of our journey our souls reawakened in anticipation of the adventure ahead.

Tesla Factory – Fremont, CA
It was a brand new day overflowing with warmth and sunshine as we set off for Fremont, CA to visit the Tesla Factory. Just as my expectations of the car were exceeded, so too were those of its birth place. Our timing was perfect. We were greeted with an engaging group of Tesla loyalists who invited us to join their tour led by the knowledgeable Tesla team member, John H. After only a few minutes, I was witnessing the wonderment and exaltation of Charlie Bucket exploring Willie Wonka’s Chocolate Factory on an episode of Discover Channel’s How It’s Made. Far from being a car enthusiast, I found myself just as fascinated by the size, scope, organization, teamwork and technology. In fact, at one point we as a group were fully entranced for about 30 minutes as we witnessed the assembly line in action. It was clear, Tesla’s competencies spanned a multitude of areas and all of its stakeholders were deservingly proud. I was sold. At the conclusion of the tour, Peter’s eyes widened when our guide whispered to him, “Next time, don’t risk reaching a range of 1 mile.” Apparently, the guide had been following our trek along with dozens of others which was both flattering and intimidating as we looked to not only ensure a successful trip, but to supply entertaining feed.

Tesla Dealership – Menlo Park, CA
Our next stop was the Tesla dealership in Menlo, CA where Peter was to switch to all-season tires allowing for better traction, control and thus more efficiency during our cold weather precipitous inclines. I took this opportunity to indulge in a much desired and deserved meditative run through Menlo Park. This cathartic outlet was food for the soul and what was supposed to be a 2.5 mile jog turned into 4 miles of pure bliss. I returned to find Peter chatting with another electrical engineer who recently purchased a Model S while he waited for Sunrise to finish her bath (the dealership insisted she not exit the service door until her coat was as shiny as the day she was born).

Final Destination – Los Angeles
With all three of us refreshed (Peter, Sunrise and I) a couple of IPAs were in order so we hit up Menlo Grill adjacent to the dealership in preparation for the next venture to Gilroy en route to our final destination. In Gilroy, we devoured In-N-Out burgers (which I had not yet tried) while the car super-charged next to SIG1058. We returned to find another local owner #1459 charging as well. After a quick charge followed by a strawberry milkshake at Harris Ranch we arrived in the City of Angels around midnight. In just a couple more days we will have traveled almost 2,000 miles powered by about 20 hours of charge time!

Day 5 (12/28/12) – MacGyver & the New EV Tripper

This was my first day on Electric Road Trip S, but day 5 for Tina and Peter. After leaving Erin and Dave’s (thanks again, guys!) we headed out to Tesla’s supercharger at Hawthorn CA for a quick charging “top off.” A supercharger charges up the battery to full in about an hour as an opposed to about 8 hours on regular 50amp stove outlet. So I started out the trip pretty spoiled. While charging Peter got so excited about talking to Larry (a very friendly navy pilot who flew F14s off aircraft carriers and now flies commercial planes and who incidentally graduated from University of Maryland, like us) and a fellow Model S owner that he didn’t plug the car all the way in so after about 40 minutes we realized that we haven’t charged at all. Oops. On the plus side, we were still in sunny southern CA and the nice person from the Tesla facility made us coffee. In the lot on the way out, Peter showed me how the car accelerates. I’m not a car person, I haven’t owned one in 8 years, but that was awesome, it takes off like one of those super fast roller coasters!

After picking up Tina the Electric Road Trip S was pretty smooth and uneventful until our arrival in Barstow, CA a couple of hours later. The outlet mall where the supercharger was must be doing something right, because every fast food restaurant was packed to the gills. First prize goes to In and Out Burger, a must stop for me every time I’m in CA. The pandemonium going on in there reminding me that line to get into Lolapalooza in the mid-90s. So unfortunately no In and Out for me, but not to worry I’ll be back for that deliciousness next time. Speaking of in and out, thanks to the awesome supercharger we were in and out of Barstow in an hour and back on the road. The weather was cooperating with us, it was a beautiful sunny day and we could enjoy the great view of the dessert and the mountains, something us east coast dwellers don’t see every day. We even got a thumbs up from a car on the road, apparently some people know what a Tesla is :) I’m not going to go on about how beautiful the moon was over the dessert, because you just had to be there.

We pulled up to an RV park in Kingman, AZ at about 8:30pm, but then magically it was 9:30 due to that silly thing called time zone change, which we forgot about completely. And that’s when the fun really began. It was dark, it was cold, and the 14-50R plugs (or 50 amp hookups) where we going to plug in the car were too far apart (Peter needed to use two of them because of the device he made that allows to cut down the charging time from 8 hours to about 4 hours). For those of you who don’t know what I’m talking about, don’t feel bad, I already had to ask Peter about the names of these things about 3 times and I think if I ask him one more time he’s going to throw something at me. But basically, they are big outlets like the ones that you use to plug in a dryer or a washing machine. Anyway, Peter pulled out his tools and in a very MacGyver move made an extension cord right there on the spot, all while chatting up some lady that was so enamored with the car I think she already put her order with Tesla. But alas, after the extension cord was made we still could not charge car because it was 3 phase power (no idea how to explain this in plain English, please ask Peter). So off to an RV park down the road we went. At that point, it was pretty clear that we were not making it Flagstaff, AZ tonight as originally planned. What followed with a tour of the local motel chains (an I never seen so many motels, as I have in Kingman, AZ) in search of a 240v plug to charge the car overnight. Luck smiled down us at Motel 6. Tina and I got a good laugh from watching Peter just walk into the laundry room of the motel without actually checking in and inspect the plug for the washer and dryer. It would be even more funny to watch him explain this to the motel stuff. Luckily, after another MacGyver operation, Peter pulled one the pins out to make the plug fit. The great people at Motel 6 let us use the plug to charge the car. It was just in time too because my battery much like the car’s was pretty low on charge. I haven’t slept so well in a while. Although Peter and Tina tell me that that is the earliest night they had so far (we passed out around midnight) so I guess I’m still a lightweight electric road tripper.
