I was watching some videos on the mess that happened in Chicago last week. Some big EV guy, who lives in the cold, flew to Chicago, went to the charging stations/talked to owners, analyzed it and here are a few of the issues.
- Uber/Tesla-I had no clue that this was a thing but apparently Uber has some deal with Tesla to rent out their cars. Their best estimate was that 80% of the people waiting for chargers were these drivers.
- Uber drivers that are interested in renting a Tesla must have completed at least 150 trips and maintain a 4.85-star rating to be eligible. It costs about $300 a week to rent the Tesla, and drivers receive an extra dollar per trip (max $4,000 a year) and are enrolled in the company’s newer “Uber Green” ride-hailing category.
- Uber/Tesla-This program has been in place for a little over a year. Most drivers have never had to deal with how cold it got. Most, had no clue what preconditioning does. In the summer, if you don't pre condition, your charging just takes a little longer. Preconditioning in sub zero is a lot more important, If you don't precondition, the Tesla Supercharger is going to do the preconditioning to get the battery above freezing. This makes the driver think that there is something wrong with the charger, so they unplug. This seems to be an education issue. Not just Uber drivers, but any Tesla driver that lives in a cold climate. Also, a lot of EV rentals.
- Chicago-The majority of the issues, were inside the city. Those that were on the interstate traveling, didn't seem to have issues, which points back to the preconditioning issue. Most people that go on road trips, use the Tesla software to plan their route/charging, which would handle the preconditioning before you got to the charger. Also, the charging infrastructure in Chicago, even during good weather, is lacking.
- Non SuperChargers-The guy went two days after the crisis and there were still people that had their EV's parked, waiting to charge. Surprise surprise, Electrify America had chargers that were not working.
- This issue wasn't reported as much in other areas that were just as cold as Chicago. Most of those cities don't do the Uber/tesla thing, but some do.
- Outside of Chicago, some other areas had issues with snow. e.g. The Kum and Go in Grinnell, which has 8 chargers, as of yesterday had still not plowed out the area. This is that Kum and Go's responsibility. Hy-Vee and other Kum and Go locations across the state were fine. I'm going to guess that they are going to get a lot of blow back on this.
- If you charge at home, this isn't an issue. Your home charger will get your battery above freezing and then handle the charging. If you're using 110 at home, charging could take a LONG time if it's really really cold.
So in summary, as much as I'd like to think everything is perfect, there are still things that need to be improved. I'm a little worried that you'll hear more and more of these stories in the future when other vehicles start using the Tesla Superchargers.
