Looks like the only two lockout options for it are 1) a specific Tesla, or 2) just Teslas. Which makes sense since the J1772 standard doesn’t come with any authentication spec. Tesla has extended the spec, but only their cars talk the extended authentication spec. More info on lockouts with...

Tesla was just under scrutiny for various FSD problems resulting in a recall. If it routinely ran over children, you’d think the government agency would have noticed and done something about it.

Most are OTA software updates, no service trip required. Rivian will have a lot of these too.

Tesla has never made a J1772 compatible vehicle. As to why they make it (they currently sell a gen 3 version of their J1772 EVSE now), maybe because they can make money at it? Also, these Tesla EVSEs have the nice feature that you can share a single circuit among up to six Tesla EVSEs. In a...

Absolutely correct, the reason I said dont freak out if the electrician uses 6 gauge Romex for 60A is that a lot of electricians do that anyways. That rating is meant to protect installation for worse case scenarios like running Romex above the insulation in an attic that could hit 130 F in the...

Seems that the previous occupant had an EVSE that could be plugged into a 6-50 outlet. If you are paying full price for your Rivian EVSE, I’d recommend checking out other EVSEs that can plug into 6-50 receptacle and call it a day. 40A vs 48A charging isn’t a huge difference unless you routinely...

EA charging above 200kW has been known to cause problems with Rivian’s (and some other EVs) in the past. Hard to pin down since EA uses like 5 different manufacturers for their DCFC stations. Nonetheless, the theory is that these stations are giving more power to the battery than the car is...

I don't think we have enough data to know what is really going on. I would love for someone to do similar measurements in a warm weather climate and maybe that would give us more data to form a conclusion.

Good PSA. I do have the Rivian EVSE, but I use a separate Tesla Wall Connector for my Tesla. It is interesting because that Tesla J1772 adapter has been around for like 10 years and I’ve never heard of anything like this happening. Were you charging at 48A? Edit, not that it should matter, the...

Which Tesla adapter did you use? Oh wait, it would have been the one that comes with Teslas, doh.

I will be very interested to see what happens to these tests when the weather turns warmer. My suspicion is that cold winter temps are having a big effect - my theory is that the lower layer of battery cells is much colder than the top layer, yet they have a single shared cooling plate in...

It isn’t next to nothing and you can be sure it’ll be a lot more than the number Rivian will install. Gawd, all this whining and hate directed at Tesla is ridiculous. Without Tesla, we wouldn’t have Rivians.

March 1st is Tesla investor day. We should learn more about this then, if not before. Incompatible charge port placement is an issue. Not sure why the non Tesla industry didn’t think about this. All Teslas have identical charge port positions. The rest of the industry changed positions just for...

But EVs have advantages over ICE in other areas. They drive better with single pedal driving. They accelerate better. No urban pollution. No garage fumes. No gas station visits. No oil changes. More cargo space (frunk, no transmission hump, etc). Safer in an accident. Better boat launch...

Well, magnets on rarely opened frunk covers is an easy place to save money. But the rest - the entire vehicle industry to struggling with making EVs cost competitive with ICE. It is very, very difficult. People deride Tesla for minimalist interiors, but that's one way Tesla gets costs down to...

Sandy and Rivian are right to reduce costs. As originally built, it should have retailed for over $120K. They can‘t sell 150,000 trucks a year at that price and that’s what their factory is set up for.

Awesome. So they draw a max. of 12A each. That's how you do a proper load calc, by the way, you look at the appliance's sticker to see the true maximum amperage draw. Anyways, now your household load calc has this: (2) wall mount inverter heaters - 12A each, for 24A total. double electric ovens...

And by the way, two 200A panels doesn't work. At some point in the chain, you need a breaker that protects the total load of the wires coming from the meter. In practice, that means a 225A breaker is needed somewhere along the way, so see my above post.

Which Tesla charger? And he has a Rivian, which needs a J1772 plug. The Only Tesla charger that has a 6-50 plug option is the portable charger (called the Mobile Connector) for $230, then you'd have to buy the Tesla 6-50 adapter for $45, and then you'd have to buy a Lectron or other Tesla to...

You want to avoid this if at all possible (and I think it is possible, see below). It is costly and it isn't sure that your conduit would support thicker wires. But they do make 225A combo boxes. Click here to see the Eaton catalog pages (they make a 225A combo 20/40). And that should work...
