Tesla Model 3 Power Conversion System

Here is a quick look at the Power Conversion System (PCS). This module is located under the rear seat in the “Penthouse” and functions as the AC to DC on-board charger as well as the DC-DC converter that keeps the 12v system going.

A Texas Instruments TMS320F28377DPTPQ is used to run the PCS. http://www.ti.com/product/TMS320F28377D

Thanks very much for making all these videos. You do a remarkable job at conveying both the elegant simplicity and magnitude of engineering that have gone into this vehicle. I appreciate Model 3 substantially more now that I see how astoundingly well integrated and designed the system physically is. It suggests extreme robustness, reliability, and longevity, which are ideal adjectives to describe a car, in my opinion. I am stunned at how thoroughly the engineering of Model 3 distinguishes itself from essentially all other vehicles being mass manufactured today.

I’ve found somewhere that the drive motor’s stator isn’t a solid one but multiple axial part with lots of gaps, which is unique and makes me confused ! I suspect that structure is for air cooling but my colleague says it’s oil cooling. Now, only more details from your amazing sharing can prevent the “bloody” fight between us (just kidding LOL.
So, I’m Looking forward to the detail teardown of the drive unit, especially the connection between drive motor & gearbox, the oil loop between them, drive motor’s elctro-magnetic structure and cooling structure. ^o^
Thanks again~

Looks like they split the phases, one AC-DC converter unit per phase

oisiaa says:

Any idea how many Watts the 12V system can output? I’m curious about running an inverter for emergency house power during an outage.

Dan Frederiksen says:

What power levels are we talking about and can you write parts numbers? mainly the caps and the transistors but also the unusual transformers if they have parts numbers. I also wonder about switching frequencies. It doesn’t look like fast resonant topologies although the 12V is very small if it’s just the corner. Maybe it’s only say 400W or even less.

Hodge Podge Productions says:

Are you sure the strips between the transformers are actually part of the board and not just bolted on top? Seems like it would bridge two separate PCBs.

John Smith says:

All these Model 3 videos are great, but as someone who isn’t too familiar with the various hardware being shown, they would be even better if you used a laser pointer (or something similar) to highlight/indicate exactly what you’re talking about. I know you’re pointing the camera or moving it closer to “zoom”, but if one doesn’t know generally what something looks like, a non-ambiguous indicator would help a lot. Thanks for the interesting content and keep up the good work.

Yeeaaahh. 0:45 3-Phase Charging. So i don’t have to cancel my reservation. 11kW AC is good, but 16,5kW like the Model S/X would be better. 🙂

Thanks for you insights in the Tesla systems.

Tony Rocco says:

How are the magnetics terminated to the board? At 2:09 there looks like some kind of receptacle. I’d like to see some close ups.
Great videos. Thanks for taking the time.

Ken Sturgis says:

Great video, thanks for making these. Just as a note, it can sometimes be really hard in a video to determine scale. Since we never see anything of a known size in the video, its tough to determine scale. Pointing at something, including a quarter or a soda can, can provide a sense of scale to your audience. I look forward to more videos.

Alex Jung says:

thanks for all these videos do you know how much power you can draw from the 12v converter and what is the voltage of this converter is it really 12v or 14.4v thanx in advance

tesla engineering is a dream

mondayfool says:

The trick in this board is the cold plate. Although I can not quite scale how much power and heat it actually handles, but to keep it compact I think the trick is to have it all cooled to keep the mount of copper low and traces reasonable and without additional busbars. I am a bit surprised not to see any or many high power board features.

etbadaboum says:

Great! Much more soothing camera moves! 🙂

Markus Strobl says:

Any chance of a Model S series? Like a tutorial on CAN bus monitoring and diagnosing faults? How to do diagnostics without the Tesla toolbox, for example.

rif42 says:

What type of 12 V battery does Tesla 3 use?

Alex Wendt says:

In the eu the tesla ac-chargers (S & X) support 11KW (3x 16A/230V) @default and 16,5KW (24A) upgrated through software. Do the numbers on the fuses add up to the math?

mondayfool says:

Are you familiar with the EMC and other electrical safety regulations? I just wonder how tesla actulally holds up. Nobody has put tesla through those afaik apart from tesla itself for the type approval. Sometimes I just wonder how they manage with such compact and high power components.
e: I am not familiar with north american regulation and I am not sure if tesla has got their type approval for the rest of the world (unece) yet. As always it is interesting to see if they need some changes, they would not want any.

Mitchell Barnow says:

The Model 3 is an incredibly complicated machine. No wonder Tesla has not made any base models. How could they make any money?
