On gen 2? I haven't personally dug into the inverter on my truck, but there's an old thread around here (pre-gen 2) where someone did, and there was no HV cable going to their inverter. Maybe this is something they addressed for gen 2? On my gen 1 truck, using the 120V absolutely destroys my...

The HV battery charges the 12V whenever needed (regardless of if the vehicle is on or not). It can’t deal with a totally shot 12V battery though.

The 120V inverter runs off the 12V system, not the HV battery system. So if you try to use the 120V to power an amp, you’ll actually be making it worse.

I ordered a new F150 King Ranch on May 28th and I haven’t heard a peep. Apparently there are people who ordered a 2024 F150 LAST YEAR and still haven’t received a VIN or their truck. Rivian is in good company it seems.

That’s stupid. The appointment was for an in person appointment, not a phone call. What’s wrong with people today that they can’t even knock or ring a door bell? The same goes for food delivery now. Why did Covid suddenly make it ok for a delivery driver to just leave food on the ground at your...

Only for a small number of banks.

Last I checked, you have to give Plaid your account credentials. Even if you trust them to not steal from you, do you trust their security to be some magical unhackable fortress? Because if someone gets a hold of the password that you knowingly gave away, and you lose money because of it, your...

The Rivian manual says you need a WDH if you're towing anything over 5000lbs. That's at least 8500lbs with no WDH. "Do as I say, not as I do" I guess ?.

I have 2.25 for my truck with 21s

As an electrical engineer, that was my thought too. But I bought a trailer that simply connects the battery directly to the trailer plug, and it works fine. You can probably get away just fine without a real charge controller between the vehicle and the trailer battery. Maybe a lithium battery...

What’s the question? ?

You can put it in show and tell mode to test the running/parking lights. Then I just usually use the hazards to test the brake and signals. On a 4 or 7 pin connector, the brake and the turn signal is the exact same wire and exact same bulb. If turn works, brake works. Using the hazards let you...

I used these ones. While the tow mirrors are of nice solid construction, they do shake. They shake because the plastic Rivian mirror housing deflect a little. I think any tow mirrors with a single arm and two clamps will be the same. I tried mounting on both the top and bottom of the Rivian...

Sure, but not if the sub is inside the plastic tub.

Haha, I don’t think so. PWM works fine if we’re talking about a few watts through a buck converter, but that’s not how high-power power conversion works. Anything converting DC at this sort of power level is using ZCS or ZVS to keep losses down. And if you’re using a power conversion topology...

I'm not a power electronics engineer specifically, but this feels somewhat wrong. It's not like they're just using a bridge rectifier, a cap, and feeding that directly to the battery. They still need full power conversion to control exact voltage and current requested by the vehicles for various...

It depends what you mean by control. The vehicle does *dictate* what power comes to it from the L3 EVSE, but it relies on the EVSE to do what it asks. This is different than L2, where the charger is actually on the vehicle.

For V2V maybe? For normal L3 charging, no.

Not technically an inverter, but similar-ish looking power electronics. I’m reasonably confident that the two large contacts on the L3 plug are basically just routed straight to the battery. There’s a contactor in line for protection, but no power electronics. When charging from a DCFC station...

I take it the JL sub couldn’t be made to fit where the factory sub goes?
