[Dormant] Electric Vehicles

This is going to be a bit long. If you want a better explanation, here is an excellent (albeit a little outdated) video on the subject: https://youtu.be/Iyp_X3mwE1w

BEVs are a little more complicated, but not that much. There's 3 main levels of charging to be aware of.

Level 1- 120v AC charging. Connect to a standard (and hopefully isolated) wall outlet. Your charging cable delivers this straight to your car, which then converts it to DC to charge the battery. Also known as trickle charging, it adds about 3 miles of range for every hour spent charging. It is almost never seen outside of home charging.

Level 2- 208/240v AC charging. Similar to the above, except you either have a 240v outlet or the charging cable) station is hardwired directly. Specs vary, but common configs are 5-10 times (7-12 kW) as fast as level 1. Still delivers AC directly to your car. This is also what you see at hotels, parking garages, etc where you are not going to be sitting there waiting on it. The required infrastructure is only some heavy-duty AC electrical cables and a way to bill you. Levels 1 and 2 use the J-1772 connector. Tesla calls theirs Destination Chargers.

Level 3- DC Fast Charging. This is an interesting idea- why limit yourself to the (relatively) puny charger you have onboard the vehicle? Or bypassing the normal limits of how thick a cable must be? These chargers, using the Combined Charging System (CCS) standard have an extra set of very thick pins that connect directly to the battery system. They deliver as much as 350 kW (depending on car model/capabilities) of DC power, straight into the battery system. They also have water-cooled cables to deliver that much power without an unwieldy cable. These are what you see at truck stops and places where people are going to be waiting for the charge to complete. Tesla calls theirs Superchargers.

The Tesla connector was recently opened up to the world as the North American Charging Standard, or NACS. Many other manufacturers have already announced a switch to this. For the J-1772 connector (levels 1 and 2), this is basically the same thing in a different shape. It's even electrically compatible, so a dumb adapter will work. But what's different is that the charging pins are much, much bigger. It can handle a level 3 DCFC on the same pins, albeit with some additional circuitry to handle these different modes.

Can’t charge at all. PHEVs don’t really need fast charging anyway.

I'll be completely upfront about my biases here: I'm not really sure PHEVs make a lot of sense. You're getting a small battery pack that'll still be expensive to replace (if you can find the packs later on) with the maintenance of a gas car. Personally I'm not really sold, but hey, if the numbers work out for you, have fun

I'd say if your current car is on it's last legs, go ahead and get what you want, but if you can hold out for a couple of years, I'd suggest maybe waiting to see if prices on full-battery EVs come down any.

Most of the PHEVs I’ve looked at top out around 50 or so miles of EV range, and that pretty much covers all of my day to day driving with some to spare. For extended trips, I don’t see myself topping off the HV battery unless I’m lodging overnight or something.

Yeah, in a PHEV your charging is almost entirely going to be when you're at home or staying somewhere for a few hours (shopping, hotels).

Does that mean they can’t charge at all from those, or they just charge slower? Thinking of like if a hotel had a charging station, for example.

They can't charge at all at DC Fast Chargers. If you see a bank of chargers out in the middle of a parking lot somewhere, odds are you can't use them. If you see some chargers on the wall of a parking garage or on some posts in front of a hotel, generally you should be fine.

If you get a few minutes this evening, take a look at Plugshare (https://www.plugshare.com/). Go to Filters on the left, scroll down to "Vehicles and Plugs", and make sure only "J-1772" is selected. These are the places you'll be able to charge.

Glad I posted this because I was just assuming the charge stations worked like gas pumps and I’d just swipe, wait a bit, and go. Apparently not lol.

So with a PHEV, unfortunately not really. You'll need a couple of hours to charge a PHEV at a charging station. A full battery EV can only get a gas station-like experience because the DC Fast Chargers can push an insane amount of power very quickly.

I'm sure you've seen the figures that the average American drives ~40 miles a day. That's where the ~50 mile range PHEV battery comes from.

The question is what happens when you need to go further than that. On early EVs (like the GM EV-1), the answer was honestly to just find another car. That limited its appeal to just being a commuter/second car.

PHEVs answered that by including a gas drivetrain, although some now are just a gas generator. BEVs answered that by including a giant battery and enabling fast charging (as a concept, not necessarily as a product)
