UPDATE: https://youtu.be/UkRk2OQI7RE (Though you should watch the current video first!) NOTE: This video is only about whether the Model 3/Y can do V2G NATIVELY as was widely claimed across then internet by misinformed people. I show that it's physically impossible to export AC from a Tesla PCS. Yes, you can add several kilobucks worth of hardware to make a Tesla generate AC (I have done this), but that's not the same as the "built-in claim". In this short video I review the Model 3 PCS (Power Conversion System) and it's architecture. Lately there has been a lot of news that claimed that Tesla had quietly added V2G (Vehicle to Grid) functionality to Model 3 (and possibly Y). This is based on an Engineer's findings who did a Teardown on the PCS in 2018. Well here I have a PCS also out of a 2018 Model 3. I've also looked at a lot of others, including the stripped down model used on the Standard Range Model 3. So far none of them use synchronous rectification, which would be needed if the unit were capable of reverse operation. Also, I regularly study Tesla's software releases, and it would be obvious by looking at the code if they were adding such a capability. Now this doesn't mean Tesla isn't going to do this, but as of now, none of the Model 3 PCS units I've looked at have this capability. Here's a high res pic: https://lh3.googleusercontent.com/ZfTMiK81E1F378qlrpZRpknFqY20ix8dPTlh_WnWFBoTvE0Pr6ECjWsxfJjck1PLkX9xecydcH0IoiUk8Vqb1akhejQepsKHZEbyC9DQdCq008gMD-TgUoMcbd7Mf1Q49ZyIiAQ60o8=w2400 Tech details: The Main microcontroller is a dual-core TI TMS320F28377D. It has 24 hardware PWM channels. I don't think this is enough for a full V2G-capabile synchronous rectification stage anyway, so if they wanted to add it, it's much more involved. These novel inverted DPAK 7 pin power semis are all custom marked. In the PFC stages we have Q1003, Q1004, Q2003, Q2004, Q3001, and Q3002 marked THY30. Also in PFC: Q1005, Q1006, Q2005, Q2006, Q3005, and Q3006 marked SCM65. In the chopper stages: Q1007, Q1008, Q1009, Q1010, Q2007, Q2008, Q2009, Q2010, Q3007, Q3008, Q3009, and Q3010, all marked SiM99 which I think are SiCFETs. Finally, in the output stage we have full-wave bridges formed by D1003-D1006, D2003-D2006, and D3003-D3006, all of which are marked SiD600 which I think are Silicon Carbide Diodes. I can't locate ANY of these parts, or even this package anywhere. So I think they are custom for Tesla. If anyone knows, please let me know! If you have any other questions, please leave them below. I'm happy to answer them! UPDATE: I have also looked under the cover of a brand-new 2020 Model Y PCS, and it is the exact same PCB. They have NOT updated it at all. Since then I have also looked at a April 2021 Model Y PCS. Same unit.
