关于凝露问题的说明 II
From my guy and I know it's okay.
All right, maybe.
Jason.
Do you know is joining this meeting?
Yeah.
Okay.
Just like these. Hello. Good morning together.
Sorry for my late. You welcome check. Hello.
Yeah, on me David. I think we can start with the due test yet, and then, once Pasino joints, and we can discuss EMC, okay?
We can use the type that progressed decade the department management and then the hardware analysis can be reduced by this. Okay?
Okay. And okay. So, I will take over the topic for the, for this for this. Yeah, it's okay. Yes.
So okay, there's my screen just a moment.
Yes, sorry, please go on.
Sorry for that. I'm asking you if you want to share something, yeah, just look agenda mission.
Have you share maybe some information for for your style?
Mmm, cancel my screen.
Now this on? Yes, I'm so just mentioned, we? Yes. So, this is the general setup for the d test and this is all also before this test of it to the picture for disabled, for the different directions.
And yeah, this is the duty in the chamber. We also took the picture but this is the draft information for your style. We will we just are working on to prepare the final test report for this.
Yeah.
Any and questions you can directly ask.
Yeah, I have a question for protestant.
Usually get to have you every morning to the temperature of PCP board and you can download tester a currently for this, you mean for the PCB sensor or or the outside?
Yeah, there's one item in a standard that you needed to monitor the PCB temperature and the PCB temperature should be one to two degrees lower than the chain.
But temperature, I will to check. I will check here.
Yes, please. Yeah.
So in your, I can see that, you know, the chamber, what it's how how the sample was placed, but I can't see there any some more carpool to money to the PCB temperature,
I will check with, sorry, just a little moment. I will check the this information. Maybe just a moment.
Mmm.
What we're gonna. Sorry. We're gonna say sorry for some Chinese discussion.
Yeah.
On be Hello full facility. I also information. Yeah. Sorry for that I back and we put the sensor and under of the of the DOT and but maybe in the final report we can to maybe to recognize the sensors location and I'd the top of the US December.
We also start the DNTC sensor. Yeah. So but it's not mentioned in the in this pictures. Yeah. Okay.
Yeah, so so and yes, please, yeah. Okay, please continue. Okay, okay, so I would go on and this is the some information about the share this ass and so the technical studies just to prepare the test result and also for the PCB level,
the analysis just in mentioned, maybe is the next step.
So yeah, this is the information for outside currently. Okay. Yes. So you haven't performed any functional checks after the test. Yes, definitely. We also check the demonic.
Sorry, the second breaker can show function, and also ambient. So so no calories, no, sugar breaker errors. No changes in the voltages and currents. It count 30 as well as in, you know, cal 14. We open. So my first question is during the test.
Did you see any changes in the kale 30 current? Sorry, and you mean for the DC power supply?
The current value is minus 10.
Correct.
Yeah.
You have connected an ammeter.
A current meter at KL 30, right? Yeah. But we choose one of this not posts of the three three part. We just like sorry I make this picture. Much bigger.
Surf that. Yeah, just a moment and making the top. Yeah, you can see we monitor one of this, just for the for the full video number. Yeah.
For the number one, we monitor the DC power, currents value. Yeah. And you do see any variation, what? Well, the test was ongoing. I for this food for this data video. We also loading and need maybe.
Yeah, some time to test the data from the outside laboratory to our side for this one. But the durian disaster.
We can see this is the normal value currently. And that is, that is that is after the test I was asking about during the test to do.
Did you see any changes in the current that is something which need to be monitored during the test? That's a test requirement. Yes, for your disaster.
Keep the the PM BM maths. Sorry for the keep the DOT in this sleeper model. That's right.
But in the sleep boys in the current yes there's quite some current that you need to monitor.
Yeah.
Yeah.
With the ends, okay?
Okay, so you have that, you have that current specification in your, in your product specification.
So is that current exceeds that product specification values by how much
And what is, what is specified value in your product specification?
So you have exceeded it by 10 milliamps.
I can say it's medium or microamped providing you micro micro so so easy, you know in our standard there's you need to check the function and you know, tattooing test especially during condensation and period.
So how is it a function test? So young this season sleep mode?
So yeah, I know you sleep mode that you know you need to you know standard it there's a need to check the function for some time he especially during conversation period. Not on.
I think our standard, there's some damage.
I think I will, let me try, let me find it on the shirts chat.
You know, in 2.4.5.
Okay, let me
Micro.
Ice and maybe the requirement is through chat. Can you can see your messaging chat EBT. I just to check. You send the picture?
Yeah, to think, I guess animation, my screen.
This is item here, you know, for 2.4.4 as monitor TCP temperature because zebra temperature is higher our exits.
These range and the conversation may be different. So this is why we need to monitor temperature.
And also for this item, we need to check the function and 15 seconds and duration 2 minutes.
Sorry. So you mean during this year? But unfortunately, for the car in the cycle, we joined this stat.
We keep the duty in the sleep mode, and after after the test, we we we perform the defunctional check for this cycle.
Okay, so I shared this this we'll talk to you guys.
So you can see there's local to a anomalous causing temporary temporarily just during condensation function of thought in custom effects.
So I I heard that last time you, you conducted a redeem, has the waste red case and you checked. The I said, as I heard some guys that that when they when you conducted the tester, you have monitor that the cell different, the cell voltage and is different right out of limit. I can say. And even the second breaker was so important. Yeah, yeah, yeah.
That's true.
So well, now that the only checks has a function after the test, right? And during tests with never check the function, yet during this test, we keep the duty under this sleep mode.
Yeah.
White in, you check the function during a test.
Because yeah if if we keep the inner steel model we can't do this.
Sorry that we can't perform this.
Why the case it could be, you just use current message to wake up PMS. Yes. So big because we share the the operation mode.
Maybe. Yeah. So, for last meeting I'm not sure, sorry, but yeah. And just, yeah, if if we keep in the keep keep, keep it during this test in the sleep mode.
And we we count and to change this.
But nevertheless.
So, the proposal is we we have to to retaste or
Okay, I can't say too much.
I think I can by constables that when you reconduct the test, there should be some normally.
Yeah, sending advice.
But yeah, but what anomaly could be?
I think this could be. And so now you most likely it is almost sure that, you know during the test, if we try to turn on the BMS it's gonna cause some issues like CB will be opened or variations in voltages.
That is for sure because it's happened already with the case on and without the case that it's going to be even worse.
Yeah, here.
Yeah. So in that case, yeah in that case young.
What do you think it?
Is it going to be a failed or because in some parts of the PCB, the conformant coating is missing and that is the reason it causes the functional failures during the test. Okay.
I based on my experience, I cannot say it's a, it will fail or not.
But later I think later I can give you guys a introduction about the background of doing test.
And actually, last time I checked the Carmelo and he given me the background introduction. Then I know why should wait either doing test?
Yeah. And yeah, and I think after it's introduction I and I I get some knowledge about.
We need to do that and though why the parameter sets here, why I need to I do need to check the function because it could be happen and it could happen in our normal and say normal use of this module visit to intestig just to give us a to simulate.
Let's say the the doing condition in our, in our application, in our car. And so I also last time I told you to invite the Camero so just because I based on my experience and my knowledge, I can't judge whether it's okay or not, whether we need to reconnect the test or not, I think he's invited to this meeting that you have invited. You are you man? But as he's calendar, has a conflict with this. Another thing is, you know, maybe you cannot may not be answered without being able to answer this but then this just was also connected at back level.
The behaviors is inside the pack and that time it was a pass. Probably.
Because the aircraft inside the pack is minimal and the condensation won't be that high. Yeah, I yeah, I agree but I think this that's the white thing. We do it on a pack level, why don't we classify the conductor? That's unpackable, is because we we have found a lot of issues in our cars.
And even if we we we have conducted our summer here some more humanity, circle things like but like that but there's still some thing happened in our car and there's still some videos and yeah I think later I can give you guys a brief introduction if there is enough time.
Okay analysis, maybe maybe Jason can give the answer.
Yeah.
Okay.
So, how either function as the after after the test?
Is it okay I'll function is okay like quotes on the current CB voltage money.
Current monitor is without a parameter, okay.
Okay to.
So, what parameter did it have test have date test?
Okay, guys. Yeah. Okay. I think there should be a detailed table. Recorded all the parameters before test. And after the test, right?
Yes.
Okay. So later we can to you as use a next Tuesday.
You, you guys can provide the detail, the report, right? Yeah, yeah.
Also, please make sure that we have clear close up pictures of the PCB world site to look for to look for any any deformation or corrosion blisters or anything like that.
Okay, okay, the teachers should be clear enough okay.
Under of.
Okay.
So is there an arrow topic?
Is Jacob and EBT?
Yes we have EMC topics with the 0, adding young longer.
Free to drop your call if you want to because he actually yeah, if you want to stay.
Also.
It's fine. Yeah, I would there. Okay, I will, at least. I will just listen. Okay. All right. Thank you. And sorry for my interruption. Yeah, I have one. Maybe on. Open topical wants to calcium from generic side.
Measurement screen. Yeah. Yep.
Thank you Council messaging again. Sorry that. Yeah, on for the, for the year, remember to test and the this season mechanism mechanical test, currently with system difficulty situation because during this test, we also have the current profile on. But we booked the yes, and many and outside the tester laboratory, but yeah.
Maybe our suggestion is could we can't you?
Maybe reduce the current and from 30 and page who may be much much lower because for my personal understanding on the current profile it's just too maybe monitor the the electrical connector functions. And if we give the the current value under during this test, we can choose to information out the electrical connector was fine.
So yeah, this is our side of the proposal.
Because maybe, yeah.
But what was your issue to mean to to have a current of 30 amps? Sorry. So what is your problem? We maintaining a current of 30 amps. Yeah. On because during this test, if we book and also the test, the mechanical shock our maybe the disaster bench and the durian test test bench on the labor. The laboratory halls, without on much higher like this while you the DC power. Yeah. Because during this test to be how to also change the the duties operating mode and also maybe so.
But we also get that.
So you you? Yes. So from very God is suggestion of 30. He said in latest plan or in the specification.
Yeah. But yeah, but we face the difficulty was done. We can't currently we've found this life on this ditch desserts. Start test company have the two results as the same time.
The test bench also have the the DC power. But if we, yeah, we can choose reduce this value to maybe much lower level.
And we can count this, the outside, attach the results currently We have a problem in this power, supply capacity to power on the Duties at the same time. Is that your difficulty?
Yeah.
Nevertheless, we can, we can to send the oil proposal and this this document maybe you have the internal and yeah discussion maybe and the weekend your feedback is okay or he can share this slide to me please look and you might feel back to you. Yes, yes, yes. Thank you advice. So clear for my side. Sorry. For my interruption and maybe please go on.
Sorry.
Okay.
Okay, let's switch to the EMC, topic. That's what I have. You received my feedback on the EMC. Test plan. Sorry, the specification.
Yes, I already cut your feet back.
All this changes or test pack?
Yeah. Is is that clear with you? What? What you need to be done on display first of all sorry to specification. Yes currently you have bricks discussing tonight? I think it's Korea fast. Now we are revised testification now and hope we can provide it again to your site for proofs tomorrow.
Yeah yeah so in addition to that feedback from our EMC engineer I think Jason is also planning to do some changes.
Yeah, using include those changes as well and highlight that.
So that the general engineer will understand what are the changes made in the next version. Yes me.
Okay, show my screen. Yeah.
We have some changes for the test specification, but I think we need to check internally for that but I can, I think we can see the changes country that let me show my screen.
Yeah, he's my screen a webinar.
Yeah. Okay.
So we have changes in the just my yeah.
Here, I have a market yellow for this changes. Now, you can find it. Yes. And also for, yeah.
And also for the age 13.
So if something see also we have a date here. Yeah yeah and also for 38 also have some this kind of changes.
I'm up here to update your connecting connected information, connecting information.
So okay, it's a back level so it don't have to do you have that connected information in this?
In this document, you just do a content, I guess. Now, you know how to be changing this these items or to change it. So, for this Chinese, no.
What I mean to say is you have we have decided to remove the crash car. Yeah.
So previously in a connector diagram, the crash can was mentioned. So now since we have removed it, we have to remove that writing. So so from the from the connector diagram. Yes. Okay. Okay, I have it here. Check me, it's okay.
I'll just yeah, I'm not sure.
Do you have a time to review this back?
And check it for our trash can already removed for in this version.
Okay.
16 86.
Okay.
76? Yeah, slightly go up. Yeah, so it's it's not remote still. Yeah. Okay. So I think this is not finished for this version.
We need to revise it automating. Okay?
So I think this document is not finished yet, so please remember information also, I think there was a mention about the RC network required for EST test, which was mentioned, wrongly, last time and that was also pointed out by the EMC engineer.
Can you please have a look?
There that is correctly mentioned. So okay.
Just you already know this, right?
19.
Okay.
Slightly go.
Scroll up here.
Yeah, enough 330 precover to its pills hope it's fine.
Okay, That's right.
So they don't remember it correctly.
Is it 330 peak offered and 330 ohms for 8 kB and 15 kV air discharge?
Okay, I think we will check for all the items you mentioned in the email or check it to the item by item. Make sure it's all right and you said you're going to send that tomorrow. Yes, right. So I think tomorrow chasing will be how time to reveal that right?
Jason.
Okay, yeah. So make sure that you send this document tomorrow so that I can pass it on to the AMC engineer for final review and approval. Only after the approval you can start your testing. Yes. The second question is about the test facility.
Bookings. Yes. You know, we are. Yes we are. Yeah, okay.
Nominated tech can see this? We already denominate this facility due to our pack EMC test.
Does it have a physically to do all the testings? Yes.
We can see this items approve by your side or if.
Yes. Okay yeah so I think so. And is it a jailer approved facility? Yes. This is a channel approved and all items marks by yes.
So tomorrow that is send the just certification, please also send that address of this facility with address. Okay. Yeah. So that they can check with the EMC engineer. Okay. Okay yeah yeah.
And also our test samples.
It's on the way to the test lab. I'll see you after yeah. After so, so first. Yeah.
So when it's your turn to plan to start the test content, we are following the test details plan from the test facility. I think maybe tomorrow we will cut that.
Currently the working on that.
Okay, I'll try to get it approved as soon as possible, so probably we can target for Monday or Tuesday. Yeah, we hope so. Yeah, I will confirm that.
Yeah.
Okay. Okay, then that's it from my side.
I know you want to take us through your document about your destiny. It's okay. Yeah, let me show my screen.
I will take it a shot, but
I don't know. I can't share a file with you guys are not but I just give you a brief introduction about this slide.
It's busy profile by Carmello and the, we can see some videos by, this is, I think addition and this wash machine and some video here that. But I don't come with the four in safety there just in some pieces.
This damage could happen.
But the most over customer will maneuver faces.
Can have seen and made it before recall.
So, what I feel but this is a give you some ideas about why GM records, this triple laser family because of the dozen module, something wrong with thermal module because returns and also and see the Toyota records.
A lot of costs and the JR. Can other thoughts to record recall the car because it will cost a lot. So these are record data, you can see the GM record.
A lot in 2014, but j is very at a very low level and okay. So yeah, this is something can cause moisture another, but something wrong because for easy and you like to go chemical, migration is humidity. Is a must and bias is a must.
And I only got contamination is not a most actually, but see, but leave there.
If the, if the contamination level is high, they will help that you see them happen and you know, okay? By yourself conversation basics.
Maybe this will give you some physical about content H&Y. How comes, as you happen. Yeah. Because there's the water everywhere right? Right now, you know?
Yeah, these is a chance for it's hard to understand it later.
And I was trying to give you, give us some examples that the in different temperature or in different temperature and also different entity level and a different air pressure there.
There may be some the water content in the inner cubic meter, could be different.
And I think it's because makes me regional groundwater paper but package.
Okay job.
Try air and I think there is some we can see if.
Yeah, one key job will try occupies.
This is a UP meter.
And also this is a water here, but because if it is at 30 degree, the same one HMO overdrive will hold as much as 2080 gram of water.
You can see here.
So yeah, vapor pressure and boiling the two point actually.
Yes, you do about relative, humidity, level and bridge.
Okay.
This the room and help their level please can.
So yeah, just give us a example.
If we place again in a fridge and then take it out and there will some condensation right on the cup. Yeah.
And that will cause code of vehicles. I've already exposed to one more, is the air. I believe the vehicle is called, and the travels in a warm environment, the conversation would be a lot.
And this is some, that's once we we have put our cars in the climb in the chamber.
And after of the low temperature, as the way, drop it out, there's a condensation in our car and both vapor ingress and mechanism. .
This is air, we can see there's water in air so air can in to the average, our model. Yeah, it's different ways, right?
If it is uncute, they are can ended easily if it even if because of airflow.
And if there were water tight, with with breast membrane, but the water still can intermodal.
And because of the degrees of motion, right? Even a temperature in different and the pressure in the model will be different. Remember the pressure element right through the yeah yeah the pressure element for sure.
Let's say even yeah, special element and air tight side when you install.
Even it is less completely suit the material, right?
The material kind of soap and also give out water. So if it is completely airtight this not problem, isn't it? Hmm, we have seen some problem.
Even it is completely airtight and there are some are slide below later. Okay, so this is a material. You can see the water opens option.
My visit nylon, it's 1.2, it's very high.
And, but normally, I think the plastic we use APS plus PC and think the, the matter would be very at all. But I think we have a memory in prison membrane. In our design, right? In a pack and also in PMS level.
I don't yeah, yeah, right.
This is the code that remember.
So when the car was drive out over chamber and the cluster plus these function, this is it happens just like this. And so this is a phenomenon.
We have monitors because there's we can see a lot of vacancy water vapors. Yeah. Airport. Vapors. And also it's the design is for you. Yeah.
Okay, boy.
But let's say for the user, the summary done because by it, because things like a lot of holes, what can we call this? Let's see. Yeah, yeah, use use.
Yeah, sensitive because so we can see there's a slide. Sorry there is a introduction with fluid and dustbrook it in it. Give us a brief interaction model called technology.
It is prism membrane to to lower possibility of conversation on our inner light, module like fun.
Okay, I think I can share. Let me find the link.
I can share the link with you guys and
And I think we can find it in in YouTube it's a YouTube video.
Call out dealing with condensation and is a good aspirin for introduction about source of the condensation.
I think later, I will try to find the video link down here with you guys.
And okay, this is small height enclosure with browser membrane and no conformal coding on the PCBs. See the camera with golden super pressure.
Come composition. But one thing that suppliers that, okay, our data is okay.
We cannot see the condensation in our camera but actually, we see or the first example, they deliver to JR and we we can see the condensation on PCB.
And okay, this is the effect on seals.
Okay.
This. They okay, this this video give us a brief intentional motor.
The pressure in the inner suit modules, whatever pressure or underwater side effect of residue completely stewed audio and also we can see the effect.
Once use, we can see that this is in better pressure on vents and I'm with the housing, okay? We can see this, this color line is when the housing here, another one is not bended, the pressure, you could be very high, right? So for, for a hundred, sorry, for under the housing, we can see the humidity level is a higher than 100 and sometime.
So if it is higher than 180 means some condensation, right?
You know, that means in a sealed, couldn't brush. Yeah, the chances of having relative humidity highs even higher. Yeah, yeah, chances are.
Okay.
Okay, true.
Crafts result, the camera over last both cameras that wears a very similar age. We can see for arrow. 5/38 camera.
Accumulator more moisture than narrow for one hour 405.
Usually, in our, I think this to both several camera accumulator moisture over time.
But to another catch up with regime by humidity.
This is a to prove that even it is 0 to ones and there is a condensation, neural camera.
And I think there's some point to prove that, okay?
There's some point to prove that some other seals failure late.
I was trying to find out.
Okay.
And okay, this is a flash on orientation tab weeks.
Loaded a view, but were then decent, decent blood disembends, disassembled, and checked for any annual. Observation airport, commercial, / presentation table, received something wrong with here.
And he made the temperature cycle test, operating five, humidity temperature. And I think your jaw guys have conducted this test with five out of four are all five out of five. Three, the cameras can cameras household.
They have conducted a test and not power that during sub 0 ocean, number test, I think, temperature relative. Okay.
Love to this business has conducted in our environmental test but our model has the test. But the week, we still find some issues in a model.
Ensure power is also part, required power doing something.
Okay, while strange in the testing camera on power during sub-zero but still.
No. So mechanism. I will count this session temperature, this will run a pcb effect of cortisols, okay.
Some cortisones will normally have the high possibility of condensation and homogeneous had to 90 high level and a 20 degree depression below.
The embryon temperature may result in conversation and extra.
And yeah, this orientation that the entire growth is this simulate summer?
Let's say summer, test condensation, results, pure water and dendrites. The if there's plenty 12 volt and will some either grow some bend, right then right.
If it sinks leave, all the parts are emerged in water and promotional water and there will be some suppressed Android carbon. Yeah, a couple nights some combo the internal surface and then draw the gross magnets.
Okay, it will give you a briefing that are the hardened red crews condensation and the reason this level of iconic, reward iconic accommodations and this free law end up in changes in the you know voltages of current right from normal.
Yeah, the voltage voltage difference is very important to potential. Yeah yeah. And also don't try the girls will stop if supply of water into area. It stops. Apply the voltage remote
