When an earlier version of Juicenet 40 did not support a fixed charge quota limit, I would rarely, remotely end a session. But now it is set to 8 kWh which works well. We don't have to worry about EVSE hogs.It’s no different than placing a reservation at a restaurant. If you’re there on time you get your table. If not, NEXT!
Hotels are special so when planning a trip, free charging is important. But due to abuse, the last hotel we stayed at had to disable them unless asked for by a guest. This prevented those using a near-by gym from hogging the chargers. A better solution would be an all-weather, door key to enable charging.One place that I would find this feature very useful is at hotels. Whenever I call to make a reservation and ask if I could reserve one of their electric car stations for the evening, they always tell me no, first come first serve.
Free is what lets me afford to charge and the shop at the pricy Whole Foods. It also applies at a pricy, upscale mall, Bridge Street, and my favorite neighborhood stores at 5-Points.Colour me crazy, but I for one would love to see all of the free chargers done away with. All they do is encourage people who don’t need a charge to plug-in, and create a disincentive for people from disconnecting and moving their EVS after they are full.
Here is the weekly activity of the 5-Points EVSE. We turn it off at 11 PM after the last restaurant closes and start at 6 AM when the earliest stores open:
Experiments limiting the total charge to what can be done in 1-2 hours solves the problem. Here is the latest charge session:
The rather weak charger, ~3.42 kW, took about 2.5 hours to get the 8 kWh. Not enough for a full charge, it is enough to give 24-48 miles (3-4 mi/kWh.) That EV owner works at a local office and moves the car when it is done.
Is this perfect, no. I would prefer a way so anyone on a charger can get an SMS message if someone needs a charge. Locking the J1772 should be limited to when the car is actively charging and then unlock. The simple expedient of a parking meter makes sharing of our downtown, fast DC charger easy.
