Yeah, there's no charger at our hotel, which is the only reason it's even on my mind--normally I'd walk out to a full car every day. Hotels for Car Week need to be booked a year or so in advance, and I had no idea I'd be in an EV when I booked.
I think this week is a pretty fair test of what it's like to live in an EV without home charging, so I'm glad I'm getting to see what it's like.
As Keith noted, the only 150kw+ charger is at that Safeway, and every time I've driven by there's been a line of new VW ID4s waiting to use the single functioning stall at that location. Most of every manufacturer's west-coast press fleet is in Monterey this week, which means lots of cars without home charging all competing for very limited fast charging resources. There is a two-stall 62.5kw charger in Pacific Grove, which I'm calling medium speed, as it'll take somewhere around 1.5-2 hours to charge the car. But they've been full every time, too, and I've instead plugged into a 3.9kw level 2 charger that's next to the restaurants downtown.
So what's my plan? Well, I should only have to fully charge once or twice during the week. So when I go into town for food, I drive by the 62.5kw charger and see if it's empty. Eventually it probably will be, and I'll plug in while I'm eating and be good to go. If not, I'll eventually just go wait in line at Safeway for the fast charger.
After another full day of driving around, the car is at about 35% full. That's somewhere around 100 miles, so I'll need to solve my charging problem in the next day or two.
I see a few ways to fix the problem of EVs without home charging:
- More level 2 chargers, or "destination" chargers. These fill up the car overnight, and they're what I've been using during meals since the medium speed charger is full. Lunch is worth about a 5% increase in battery on the 3.9kw charger. If there was one of these at my hotel, I would never think about fueling the car during my entire trip to Car Week. These are cheap to install and rarely require major electrical upgrades, but they're way more useful for a hotel than for a restaurant or a public parking lot.
- More level 3 fast chargers operating at 150kw+. These fill up the car in 20-30 minutes, and are what Electrify America builds. They're always broken, but that's not an inherent problem with the premise, it's a problem with the company running them. These fast level 3s are also what Tesla Superchargers are, and that network is fantastic. These would be great, but they're very expensive to build and expensive to maintain. They also require tons of electricity--back of the napkin electrical math says the Benz charging at 170kw is 708 amps at 240v, or like five houses running everything on the panel at once. This means new transformers and very expensive installation.
- More level 3 fast chargers operating at lower speeds, like that 62.5kw charger in Pacific Grove. These fill up the car in a few hours, and companies like Chargepoint and EVgo focus on them. These are cheaper to install than faster chargers, but more expensive than level 2 chargers.
So which is the right answer? Ultimately, it will probably be a mix of all of them. Convenience stores next to the highway should build fast level 3 chargers for road trips. Businesses in dense urban areas should build medium-speed level 3 chargers to attract EV drivers without home charging. And hotels should add cheap level 2 chargers to help attract customers, the same way free breakfast is a nice perk. And all of these exist in Pacific Grove, but not yet in the numbers to support the area's biggest week of tourism of the year.
This week, I'd love more 50 or 60kw chargers, meaning I could easily charge the car during dinner one night.
