Cost of EV Batteries

I'm in CA and we've heard no such orders.

PGE has special overnight rates specifically for EVs. It's not so hot then.

After seeing recent CNBC TV news report by Barry Sullivan of World Wide Exchange and the poll of present EV owners the future looks bleak for EVs.

Also recent news reports of nation wide problems with broken charge stations, lack of enough stations and range limits plus expensive cost of replacement batteries after warranty. I don't think so. I love my go anywhere and anytime gasser truck with over 320 miles on a tank of gas.

x2 on nuclear waste.

There is a factory under construction for recycling Li batteries.

Been saying to give the appliances the afternoon off since the 1960s. What is your point? Maybe EVs can charge before 3pm when solar power is excessively abondent?

It does, thanks. I know as little as anyone. Only had my EV a couple weeks but I'm really impressed with it.

Congrats. What did you get?

Yah for sure. We do a lot of dry camping so not always an option. But when we do get a powered site it’s quite often at a 30 amp site so the charging is at max 24 amp at 120 volt. Still, good for a 30 percent or so top up overnight.

Ah, so it is an actual tow vehicle.. cool.

So your level 2 charger can function as a level 1?

Yah, it can be a level 1 or level 2 EVSE. This is how it does it. All EVSE's are the same wether its Tesla, Ford, GM, BMW...doesn't matter. They all use J17772 protocol. Tesla uses a different physical connector but its still the same protocol so everyone can use any ones EVSE. With the Tesla you use a little adaptor for making it work with everybody else but that's no biggy and there are a couple reasons for them having a unique connecter. Thats another topic. The adapter comes with the car.

Anyway, the Tesla EVSE uses a series of dongles so it can plug into various sources like stove plugs, TT30 plugs, Dryer plugs, welder plugs, household plugs, 20 amp household plugs etc. I'll put up a pic. We have the most common ones we use for camping. 14-50, TT30, 5-15 and 5 -20. The way it works is the dongle plugs into the EVSE (see the pic) and the dongle has a little chip in it that tells the EVSE the max it can draw from any given circuit. So if its a 14-50 it tells the EVSE this is a 240 volt 50 amp plug so don't draw anymore than 32 amps. (Yes I know that 40 is available but the dongle is programmed for 32 amps). If you plug into a TT30 plug in a campground the dongle tells the EVSE that it is a 30 amp 120 volt circuit and not to draw anymore than 24 amps. etc etc etc .

But it gets better. If the campground voltage starts to drop lets say from 120 down to 109 volts ish, the EVSE senses this and tells the car to cut its current draw to either 18 amps or 12 amps depending on the severity of the drop. Kinda cool.

Anyway, here are a few pics. The first one is of the dongles that we carry with us when camping. They all get used from time to time, or at least if we are at a powered site and they allow charging...which is everywhere so far.



This is the little adapter they give you to plug into L1 or L2 non tesla EVSE's. There is a similar one so non teslas can use Tesla EVSE's. Handy. Without getting into it Tesla uses the same connector for AC and DC. Everybody else uses separate plugs for both. Thats another conversation.



Hope that helps. I'm not always good at explaining all this stuff as I assume the reader knows either too much or too little. :)

we’ll use the App, find a nice slow 50 kw DC charger and not worry about having to be back in 20 minutes.

Have you considered carrying a Level 2 charger with you to be able to use a campground 50a service? (Hopefully you'd never need to)

Hard to see in the pic but we are hooked up with our level 2 EVSE here. The other side of that equation is we never hook more than one thing to the pedestal at the same time so we go thru more propane on the trailer. :). Hot water etc. This was somewhere in Northern ontario. Can’t remember the name of the park.
