Use Tesla to power homes or other devices through V2X

Post by hycm0000 »

I'm a huge enthusiast of V2L/V2H/V2G. The power grid in my area is extremely unstable, and sudden power outages have been a constant headache for me. I've even tried drawing power from the cigarette lighter of my old 2021 Model Y, but it still felt inconvenient.

Recently, though, I purchased an V2L power discharge device. I noticed a lot of discussions about V2X in a neighboring thread, which inspired me to start this new thread.(https://teslamotorsclub.com/tmc/threads ... -3.140567/)MASTER THREAD: Powering house or other things with Model 3. I have my own small lab equipped with oscilloscopes and other equipment, and I'm absolutely passionate about these tools. Maybe I can conduct numerous experiments here and share the results with all of you.;)ImageImageImage

Long time no see, everyone! I’ve been a bit tied up these past couple of days. Now, let’s take a closer look at the details of this V2L—it’s been working perfectly, and I’m thrilled about it. It’s like a real treasure to me, letting me get power whenever I need it. :)

Main Interface: During normal operation, the car icon on the left displays the in-vehicle battery level and the voltage of the traction battery, while the right frame shows the V2L's output voltage, power, current, and frequency—this frame presumably represents the V2L device itself.Customer service mentioned there's a small 12V battery inside, and its charge level is indicated at the top right corner of the screen. It automatically recharges during regular use, so you don't have to worry about the device dying. The only exception is if it's left unused for six months to a year, in which case the small battery might drain. When that happens, you'll need to recharge it via the Type-C port on the back.

Secondary Interface: There are three selectable options here:

The first lets you set a minimum cutoff level for the vehicle's battery. I assume this prevents over-discharging that could leave the car completely dead—and that's definitely a necessary feature.

The second allows switching between 120V and 240V output voltages. This is an amazing function that really expands its use cases; I was pleasantly surprised when I found out about it. :D

The third one seems useless—it doesn't do anything when I press it.

Socket: It comes with one 5-15 and one 5-20 socket, which I think is more than enough for my needs. Though it would be perfect if they added a 14-50 socket for 240V use.

Customer service also mentioned they're about to release a V2H device, which can draw power from the car and output both 120V and 240V simultaneously. I'm quite interested in this and asked them for a picture.

Connector: The V2L connects to the cable via a detachable aviation plug, which helps with storage—but isn't ideal for someone like me who's always losing things. I heard their NACS connector is compatible with CCS1 and CCS2, meaning you can use different cables by swapping them out.

I’ll be sharing how it works next, and I also plan to use an oscilloscope to check out the output voltage and current waveforms. I’ve got an old compressor and motor at home too, and I want to see how they perform with it. :evil:

Finally, I managed to borrow the load testing cart that my friend built himself. I took him out to the countryside for a barbecue using the V2L function, and he was really impressed by this little gadget of mine. When I got back home, I ran some tests with his load cart. :)

His cart is equipped with over a dozen 120V light bulbs, countless 120V and 240V resistors, three motors, and two compressors. I successfully ran it at full load, and as I watched it start to lower the voltage and balance the power to 3300W, I decided to try overloading it. To my great surprise, I pushed the resistance load up to 6000W, and the V2L still kept working normally. The oscilloscope showed current clipping, but it didn't indicate an overload until ten seconds later. 8-)

Overall, it performed extremely stably. My friend's load cart can even test for short circuits, but I really didn't want to take that risk. Besides, the motors ran really smoothly, and the output voltage was very steady. So far, I'm really satisfied with it. I'll update you on its 230V switching function when I get the chance. :D

thanks for the report! I'd really love to see if you see the 15Ah discharge limit too, and if so, I'm curious how the adapter deals with it.
