I fear there will always be those owners who are half a mile away at work or shopping (or even at home!) while their cars were finished charging hours ago . . . . and someone who really needs just a couple of bars is waiting, and waiting and waiting for him/her to return
Unfortunately, my family and I experienced this situation just yesterday. Being brand new i owners (just got ours last Thursday night), we are not yet fully aware of the exact mileage we can get on any particular level of charge down to the 1/10th of a mile. This is still all new to us. This past Saturday, my wife, our two daughters, and I decided to take a trip to Naperville, which is an awesome Chicago suburb with lots of dining and shopping choices. I checked online first to see where any public EV charging stations were located. Lucky us, there was an L2 station at a public surface parking lot right in the heart of the main dining/shopping district where we planned to visit. We headed out. When we arrived and found the station, I plugged in. There is a sign stating there is a three-hour limit for the charging station. We didn't intend to be there that long. However, to be safe, I put a business card with my cell number in the window nearest the charge port with a note saying to give me a call if anyone else needed to charge. We headed out and had a great dinner, dessert and a beautiful walk on the city's Riverwalk. We got back to our car after about two hours with the RR showing 53 miles. That was plenty to get us home with a little to spare in case of traffic. (The one-way trip from our home was about 30 miles and 45 minutes.) In all, it was a very positive experience for our first use of a public charging station. The whole time we were there, we never saw another EV looking to use the charging station, nor another EV anywhere as we wandered around.
Our first public charging experience was so positive that we decided to head back to Naperville on Sunday. They have a big beautiful public pool/beach called Centennial Beach. Our oldest daughter REALLY wanted to go swimming. So, after running a few errands earlier in the day, we decided to head out in the early afternoon. The RR showed I had plenty range to get to Naperville, and then some. I knew I would need to top off once there in order to make it home without any major anxiety or drama. But from our experience the previous day, I didn't think we'd have any problems since the charging station didn't appear to get that much use.
The charging station was just over a half mile from the beach/pool. My plan was to drop off my wife and kids at the pool, go park the car at the charging station, and then walk back. My wife insisted that we drive by the charging station first to make sure it was available. We get there and, of course, this time it is in use by a Chevy Volt. My anxiety level started to creep up a bit, but I figured in a worst-case scenario they would have to unplug and leave within a max of three hours. I got out and walked around the Volt to see if the owner had left a contact card or any other info, but didn't see any. The charging station was blinking showing it was still charging. At least that meant they haven't been here all day taking up the EV spot with a fully-charged Volt.
We decided to go drop my wife and kids off at the pool, and I would come back to see if it was available yet. We got to the pool and drove around a bit to find a spot to park temporarily so we could unload everything for the afternoon. By the time we got unloaded, my wife and kids got through admissions, and I returned to the EV charging station, it had been close to 30 minutes. The Volt was still there. I decided to park along the wall near the plugged-in Volt and wait to see if the owner returned. This also gave me time to pull up PlugShare on my iPod Touch to see where other EV charging stations, if any, were near by. Unfortunately, I could not pick up a signal on my wi-fi hotspot. Our service provider is Clear, and they don't have the most extensive coverage, even in a heavy metropolitan area such as Chicagoland. So, without internet to find other stations, I decided to just sit and wait. Another 30 minutes passes and the Volt is still there. By this time, I'm sure my wife is wondering where I am. Plus, I'm missing all the fun of a day at the beach with my kids. I decided to drive back over to the pool and park. Yesterday was a beautiful day and the pool and surrounding Riverwalk park area was packed! It took me a while to find an available parking space. Before jumping out of my car, I took a brief look at the RR gauge; 33 miles. Yikes, at this point, if I didn't get a charge, I'd really be cutting it close getting back home on "fumes".
I put all that out of my mind and went and had fun at the pool. When we were done and ready to leave, everyone was starving. We headed back over to the EV station to get a MUCH needed top-off while we go get some dinner. Driving over to the parking lot, I kept my fingers crossed but my expectations low. Fortunately, when we arrived, the EV space was available! We plugged in and headed to a delicious BBQ spot nearby. Afterwards, we walked around a bit and got some gelato for dessert. By the time we got back to our car, we had plenty of miles to get home without any worries. Crisis averted, thankfully!
Through this high anxiety experience, I learned two important lessons: 1). ALWAYS find and map out multiple EVSE options prior to heading to a particular destination. Don't just rely on a known charging station being available. 2). I will always strive to be a good steward for responsible public EV charging. I will "fill up" the same way that I would hope others would do so.
Speaking of which, are there any written, unwritten, or just plain good-sense rules of etiquette for EV owners? How do other EV owners learn responsible public charging other than through dramatic experiences where they are the victims of range anxiety and charge desperation? I've decided that from now on, I will always leave a calling card tucked into the rubber trim of the window nearest my charging port. I will provide my first name, cell number, and the time at which I plugged in. And, if I know ahead of time, I will indicate how long I intend to be at the charging station. What does everyone else do when they use public charging stations?
