Lol! That intro is amazing!

Our advise, as an EV Manufacturer Start-up, would be to isolate the charger from the CAN Bus and connect to it with a laptop in order to see the messages that it is broadcasting. If there is a fault other than the communication, you will know. You mentioned this charger is from Siemens, but I'm pretty sure they are just reselling a TC Charger as it looks exactly the same as the one we use (but at a lower voltage). Those charger needs an input from the BMS, normally as a CAN message to start charging. There are 2 messages, both on 2 bytes, one for the targeted termination voltage and the other for the max DC current. Since this particuliar charger handle the EVSE (pilot and prox) itself, it might be a little different, but not that much as the BMS must be in control of all current flowing. Once the charger works as isolated form the CAN bus, like other suggested, plug back on the networks just the BMS to make sure it is still working. Maybe you have a bitrate difference between two devices. Then, you mentioned in the video that you checked the pinout of all the plugs so it should be good but a fault would be thrown if the DC connector was inverted. In resume, I think you pinpoint the trouble correctly to the CAN bus, so I would check that first with a laptop and an USBCAN or a CANALYST and have a look at what is running on this bus. Hope this helps. I'm sure we can be of more helps with more details on the build, if needed.

I have a tip for you. Your walls might have some hard surfaces, but your roof is the biggest unfurnished surface in the room. Hanging up some large acoustic panels there will definitely improve the reverb

is it just me or do some clips only have audio for the left channel?

As a comic book reader, I have to admit there’s nothing like a crossover series. Keep up the good work, folks!

Cool collaboration! Been following Jerrys EV Hummer-build as your supercar build. Great stuff!

I watch some of Jerry’s videos but I never miss a hummer video. Now because of this hummer I’m your subscriber too. Let’s get it going

This may be the KZfaq collaboration we never knew we needed 👍🏻

just a small feedback, seems like the audio wasn't equally balanced between Left and Right Stereo, hence people using earphones like me will feel that something is wrong with their left earphone, anyways hope this was helpful

Loved how every video gets between 2k and 10k views while this one got 68k with 7 hours. Most people here including myself just saw your 1st video because of zack and you sir got my subscribe because Zack trusts you ❤️

Thanks for the update! Solid work on that troubleshooting

Make sure the termination resistors or terminating nodes are at the physical ends of the CAN network. Also make sure the connections go from node to node to node etc., no ring, star or stub connections. If the slaves can auto detect the bit rate make sure the Master has a fixed bit rate. Any node that cannot auto detect set the rate to match Master. Also make sure every node has a unique ID. Hopefully atleast one of these gets everything talking.

Love the intro, love the update, good to see some progress, looking forward to the next one

What he says at precisely 7:09.5 is actually really shocking, yet fascinating. Hadn’t considered that!

It’s pretty awesome to see so many people here giving advice and being positive.

This is the first time i watch your videos . I really am impressed by the way you explained everything , it was clear and easy . Can't wait to watch more educative videos . Keep up the good work

I’d love to see a video, once everything is fixed, on what you would have done different to avoid these issues. Whether it is different parts, earlier testing in the build, or different system all together. Thanks and I love the content.

Love your channel and content, I would suggest that you use a Lavalier microphone, your channel is large and it would be a good addition for high quality audio.

Looking forward to seeing the progress on this, been following JRE for a long time and good to see some collaboration between you guys.

Just saw your supercar build project today ... nowni cant stop watching all of your videos ... Congratulations bro... from one build junky to another .. your simply awesome bro... great ambitions with the drive to match

My first thought would be to disconnect everything from CAN bus and start with just BMS and battery. If that works then add more components to bus, see, when it starts to fail. I hope the batteries are fine. Good luck!

So excited for this video.

Been following Jerry form years Now and I loved his hummer project hope it will be fixed

Thats a huge inprovements as i have been following this project from the day it started and i am really enjoying and learning a lot of things here keep up the good work definitely waiting for a new video

The amount of talent you have including content creation you are so underrated and deserve at least 1m subs. Hopefully Zack shout-out will get you there faster.

Really nice of you to fix the jerry rigging.... you should post an affiliate link (if that's possible) to that magnet/grabber tool you had. I've never seen anything like that. Would love to get one.

Thabks for helping Jerry!! Great to meet you

Thanks for the quick update. Also looking forward to seeing the project completed.

I'm so interested in the electric hummer working and I can only support you guys with prayers cos I have no clue what you need to do to make it happen. Good luck and best wishes guys. I'll be watching with keen interest and by the way Happy New Year 🙂. Subscribed 👍

So excited for this series

Nothing I enjoy and more than watching somebody install felt hexagons when I'm supposed to be watching an EV conversion video

I just love how much your videos have improved since the beginning

You and Zach are my 2 favorite channels. This was an awesome video. Well done.

As others have commented already I would try components in isolation. I have had issues in the past with message IDs clashing, checking the broadcast message IDs from each component individually would help identify any clashes. You mentioned checking continuity, but have you confirmed the BMS is waking using the output from the charger?

Want more videos on the progress, have been following Jerry Rig this entire time...!! Really excited for the fix and completion of the Hummer✌🏻

Thanks for putting a video out! After hearing that Zach was bringing it to you I was eager to watch. Glad you got a light on lol

Great synergy! Keep it up.

Great video, love the intro! Was it only me or was most of the sound only from left channel? Also, why not connect CP and PP to the orion Bms?

Nice to see you working with Zack! You may want to do some research on connecting stranded wire. My understanding is that crimp connectors should be used, not solder. The issue is solder turns stranded wire into solid wire which when flexed eventually breaks. That's why stranded wire is used in automotive applications where the wire is constantly flexing.

Cannot wait to see more of the debugging process! Good luck!

Since your pin outs are good I would start checking that all the grounds/neutrals/returns are solid. PLCs and drives are really finicky when it comes to cable noise or bad grounds. Edit: To be more clear, anything that is communications should be shielded cable that is grounded. It was a necessity in the lehr loaders I used to build and install in glass factories. I’m not sure how necessary it is in an EV but it is a high voltage system so it’s just my 2 cents.

To reduce the echo, those pads must also be placed on the ceiling. Great video 👏.

I was a broadcast engineer for years, one particular model of HDTV transmitter used CAN Buss for communications between control boards, exciter amplifier, and final Power Amplifiers. I recall a CAN Buss wiring getting a few wires shorted on the bus wiring, which took on the communications IC Chip on most of the PA " power amplifier" modules. I basically had to go online and order new IC chips and purchase a soldering station for surface mount Integrated Circuit soldering, and replace approximately a dozen of these ICs to gain back communications on the CAN Buss. I'm just putting this info out there, this all started because of shorted wiring in the buss wiring. Don't know if this is what your problem would be, but for what it's worth.

That is the best intro I have ever seen! I love it!

New to the channel followed watching the whisper project. It's a really interesting channel. keep up the hard work. I look forward to seeing some more awesome builds

Have you measured the Can H and can L with an oscilloscope to check if the signal is mirrored and if you can actually see the voltage oscillating? I would assume that the can speed is around 500kbps so make sure to calibrate the oscilloscope properly. Good luck!

I was just wondering a couple of weeks ago what Zack has done to this military Hummer. I thought he liked the Rivian so much he ditched this car but great to see it being worked on again. Love to see this functioning the way it was intended (tough off roader, occasional road car/truck).

I hope jerry completes this build I can’t wait for it

How odd - there really isn't a neutral in the J1772 connector, L1, L2, and Ground. Maybe Ground is supposed to go on top of that charger connector. Weird European charger stuff! Nice first video. I'm guessing you're right about the CAN bus being the culprit.

Great intro! Just a note, your audio is skewed towards the left channel and the video is unwatchable with headphones

Thank you for the update.

First video that I’ve watched! Love the technical aspects! You got a new subscriber!

Nice to see your expertise being put to good use... I'm convinced that electrons have a mind of their own...

Keep up the good work. Came because of Zach's car, will stay because of the cool content.

Great to have you back Jeremy time to grow the channel!

Can't wait to see the progress. You're really awesome. All the best.

nice.

There's something off with the audio. Cam u please combine stereo to mono wherever possible because the left channel has way too much volume than the right. Headphone experience isn't good

Awesome intro and update!!

Thanks very much for your care and interest in the whisper project!

Yes it's out

Is it just me or is his voice only coming through the left speaker?

Coming in from JRE for the Hummer Project :) Lets get started!

Thanks for the update! 💪👍🏼

Normally I wouldn’t nitpick, but since you care about audio, the mic’d sound in this video is often panned to the right ear, the voiceover is boomy and distorted. I still thoroughly enjoyed the content!

You may have to charge each cell individually then try again. All it takes is one cell reading under 2.7v and it wont function.

Subscribed! Love to see these updates on the Humvee project!!

love this work, lets get jerry's hummer work.

Here’s my tip: don’t put your finger where you wouldn’t put your dinger!

Not only is it the echo, but it’s also how much bass your audio has. Even losing my bass, it was still too much

i'm so glad this episode is up

just this build got me subscribed. I look forward to your other projects

Your video production is pretty good although I think the biggest room for improvement is microphones. A good mic could dramatically improve your video. I'm not confident enough to give a recommendation, but there are tons of resources online to get recommendation at any budget.

Thanks for the update. 👍 Looking forward to more.

The influence of JerryRigEverything is just amazing

I have now a new member in my favourite KZfaqr’s list , Thanks Zack!

Thanks man for being so fast with updates, we appreciate that. I follow Zack for years but didn’t subscribe yet, I will subscribe to your channel 😅 Cheers from Syria & Belgium

Subscribed for the hummer work, but excited to stay for other videos in the future!

Excellent plug on the acoustic treatment.

I am so interested in these. Great video!

It's just awesome playing with electricity, All the best, I loved your content 💕

Loving the mono to stereo jumping ❤

Unbelievable you’re channel grew so fast. Congrats!

I don't know much on electric cars, in my country Tanzania there might be few or non, but I love this project. I'm excited on the next update 👍

Definitely your channel will grow coz many are waiting for it to be fixed. Loved the project.

My left ear loved this video

New subscriber here; I like your generous and genuine approach to solution finding. Nice catch on the polarity of the branch circuit.

Great job. Thanks for doing this! The Orion BMS2 does have two CAN networks, and I think one is internally terminated, so I agree that that probably shouldn't be the error at this point. Two things I'd like to see you address are the communication baud rate and the HVIL connector setup for the Valeo Siemens. So far, I haven't found any guidance on how the HVIL should be integrated, though my assumption is that the charger is simply reading an open versus closed circuit loop.

Very interesting. I did a pin out to heavy duty fan on my Hemi

Id probably try a few things: an oscilloscope on the can network to check on the signal Check can for is the right messages are passing and any trouble codes Check sequence of operation and interlocking on the high voltage DC side for any issues (like contactors needing to be closed first so the charger can see DC voltage from the battery in the right range for a healthy battery, many chargers require that before they start re check the can wiring matches specs, I know he mentioned using some wire designed for can but the branches of the trunk didn't look like they were using that special wire, with relatively long and high speed data connections (as in more than a foot or two and into kilobits per second) things can get interesting and seemingly minor issues with wire become major problems, shielding is important, as is lengths, especially of any branches, but also things like characteristic impedance which is also why those termination resistors are needed, if you have a mismatch of the wires or miss a termination resistor the signal will bounce off and back down the wire interfering with itself, I don't know the exact specifics for can in particular but I'd expect that branch for Jerry's laptop should be terminated whenever a can device isn't connected and I would not be surprised is the characteristics of the branch wires were wrong and creating reflections at one or both ends of each branch due to impedance mismatch. I'm in IT and deal with a lot of non Ethernet "networks" for various things and I've seen a few of these types of issues crop up, multi drop bus networks (which can is) in particular can be very picky and if you only have worked with point to point or very slow and/or very short cabling (in signal time vs speed of propagation, so short here means very short, and is inversely proportional to speed, in high speed terms for things like connections to ram I side a computer or inside of computer chips, long might be well under a foot) you may not realize how important some seemingly minor specs can be.

This dude needs way more subscribers

I came here because of this project. I've watched a couple other of your videos. I'm happy I came here. I can't wait to see what happens.

my left ear thoroughly enjoyed this

My Saturday morning treat.

Love the quick video

Subscribed, I've missed birthdays and anniversaries... I'm invested to watch this thing get done! BTW I like your videos too.

Looking forward to following this series. Notifications on to the max!

Good luck, can’t wait for the second part. No pressure 😂

I was waiting for this for a long time

I have been intrigued in doing EV conversion, and JerryRigEverything have been delivering every nuance of the conversion job on his converted military Humvee. I will be watching the incoming videos to see how you can fix the Humvee and get it back on road.
