MG ZS EV Inverter Reverse Engineering Part 1

[@MrDmjay]

LOL, happy gate driver switching to all! Well done.

Hi my friend, great video

[@MattsAwesomeStuff]

5 years ago while working on my EV after a few beers, I teased Damien in the comments for his melodic accent pronouncing "three" as "tree". Ever since, he sacrifices his Irish on the altar of pronunciation pedantry and pronounces his TH's the non-Irish way. And every time it makes me feel like I bullied him and took a piece of his soul. But also, it brings me back to that moment when I had the giggles. ... I wonder to what degree reverse engineering won't be possible too far into the future if the trend of proprietary chips continues to grow :(

I think that particular joke has run its course now...

[@18avshalom]

I've lost track of how many videos this is in a row that have no cats in them.

[@Clark-Mills]

Excessively nice work, really appreciate your deep-dive and revealing / highlighting (and occasionally defusing) the landmines that industry is is laying ahead of us. Time for an open source car O/S (from display to drivers). Maybe there's already such a thing? I'm out of my field here...

I have seen mosfet before in a vesc project called axiom, you could try using the vesc platform

[@cj691]

Those SPI gate drivers are for slew rate control.

[@Brinslade]

SAIC who owns and makes the MG evs also makes motors and parts for VW, too.

Haha that reminds me. Me and my friends at college used to call them oh so silly scopes. 😁

[@petarsimic4097]

Great video! Is it planned that you will perhas do video / explanation of OpenInv software in details? Your work is really highly valuable!

[@felixokeefe]

Yes the Altera Max series are CLPDs. Also the combination of infineon and Altera stinks of Siemens industrial. I suspect they are behind most of these electric car inverters.

[@alantucker3014]

Can you not just control the inverter via CANBUS externally? Or does it have security/immobiliser to stop this ?

[@hippie-io7225]

Complexity management if an important engineering skill. I would rather have a small micro receiving commands from the 'big' micro using a CAN or uart interface. Program the micro (at the gate driver) to factor in the temperatures locally. Or how about the Tesla Cybertruck with drive by wire? Imagine getting auto cabling that is flat, with a consistent reliable connector system that is learn once, use everywhere forever. (and available from DigiKey and Mouser)

[@christianhenderson5471]

The lock picking lawyer would be proud!

[@crasbee]

I wonder if the similarity between the VW and MG inverter has something to do with the chinese espionage that VW uncovered lately 👀👀

[@bobrichards4811]

Or maybe the fact that SAIC (MG) build VW vehicles in China might have something to do with it?

[@ElectraFlarefire]

Propriety temperature sensing.

[@LatutaEV]

Oh Damien I was just getting excited and the video finished. I think you are dropping your standards on creating exidingly boring videos 😅

[@Falney]

"Some utter excitement" Is it as exciting as a powered coil on a motor?
