I noticed nothing. everything works as usual

I updated too yesterday. No bugs. Everything ok

I received the 2022.8.10.17 today on my 2015 MS 70D. I will wait too, to see what's going on! :)

from 90% to 35% there was no different imbalance at all. only first time, when I discharged the car from under 66% I got slightly higher imbalance in the range from 63% to 61%. it was about 10mv, but after it decreased to the 4-5mv. I will write here when I will go down to 10% SOC and check the...

I discharged the pack not lower than 68% and always charged not lower than 90%. I did it 5 times and at the end I balanced my HV battery pack to 4-5 mv. After that I charged it to 90% and discharged it to 35% but my imbalance was 5-6 mv after 3 hours resting time. Today I discharged it from...

In MCU1 there is no BMS reset function. I looked already in the service menu. :(

well. today I discharged the pack down to 66.2% and the imbalance was stable 13-14mv. I'm so happy to see such kind of low imbalance. No i'm charging to 90%. I'd like to get back my 4-8 mv imbalance :) I have one thing to try: I think I did not disconnected the 12v battery and Hi voltage...

Hi all, I'm back now with new data in my balancing process. As I already mentioned above, in the specific SOC range the Imbalance of brick 6 of the module 4 increases. this SOC range is 61-66% where the imbalance begins to increase and decrease. It is not depending on charging or discharging...

My measurements have shown interesting picture: In the rage of 62% - 63% SOC the imbalance increases with approx. 20 - 25 mv (for ex. from 27mv to 52mv). I don't know exactly when it begins decreasing, but at 55% SOC the imbalance was 28mv. What could it be to trigger the imbalance increase in...

Hello, I'm monitoring my HV pack continuously after my last post here and what I found out is that sometimes, somehow, something triggers the module 4th brick 6 voltage to go down: for example: 1. SOC 64.6% - brick imbalance in the module: 36mv, whole HV battery pack imbalance: 38mv. - data...

I think this is the BMS (module 4 BMB). I read a lot about it and found out, that the CONDITION X or CONDITION Z could be the problem of my pack. If it is X, than I must always keep an eye on my pack. In other case it may get discharged fully. But if it is condition Z, than, it could be self...

that's great. Yes, totally agreed. As you know, I'm trying to balance the pack at 100% SOC. as @islandbayy wrote above, I'd like to have my pack healthier and my BMS calculations more correct. But as @David99 mentioned, the BMBs and BMS are passively bleeding the high voltage bricks to balance...

yes you are right. this makes no sense to me too, because of this I'm asking what could be causing this problem?! I monitored the DC charging from 58% of SOC. from the beginning the KW charge rate was 34 and at the and 2-3kw at 100%. here is the data from 90% to 100% SOC Charge KW 90 17...

Well, you mean to charge the car to 100% and let it sit 100% charged and not discharge down to 90%? will it not hurt the HV Pack? I already charged it to 100% 5 times in a row as @islandbayy advised, but I noticed no improvement at all. Yesterday I charged it at DC Fast charger station watching...

Here are new data with average min - avg - max voltages plus today morning's valtages: Date Time Brick Voltage Min. V Avg. V Max. V Imbalance SOC%...

charged already 2 times to 100%. until now no luck to get better imbalance. Yesterday it was trying to balance half an hour at 100%. But today it completed charge at 99%. Today I began to write the data and here they are...

Hi. - if the cell has short, the brick would discharge continuously, wouldn't it? - BMB corrosion could also be there, but why does the brick always has 20 - 30 mv imbalance? I don't understand this. - Same is with voltage sensor - if it would be detached, how can I get the readings in SMT? If...

thank you so much. I will try it and write here what I will get after this charging process! Happy New Year!

@islandbayy thank you for your detailed explanation. I already charged it one time to 100% until charge was completed. The second time I charged it to 100% but had to go, so did not waited until "charge complete" indication. Any way I'll do as you wrote and will do 100% charge until "charge...

As I found out the battery pack module has 74p6s 444 cells (Tesla 5.3 kWh Module (85 kWh Pack) | Batteries | Stealth EV). 85d has 16 modules in all and my 70d has 14 modules. I my problematic module all 5 brick voltages are 3.924-3.925v and only one has 3.905v. in this case the module has 20mv...

My battery was perfectly balanced during the past 6 month (I monitor the pack this time frame). But now somehow BMS is not able or will not to balance this one brick. Here Acceptable cell imbalance range? I have got some interesting answers about the imbalance. Maybe this imbalance is ok or...

My rated range was 219 miles at 100% SOC but now it is down to about 215 in one month. maybe it is also because of cold whether we have no here: day tems max 8 Degree Celsius and nights min minus 2 Degree Celsius. any way as I understand, if my current imbalance will stay in this range, than...

Hi. First of all thanks for your quick answer. My Tesla is 2015 model s 70d 86k miles. Based on Scan My Tesla app it until last month it had all cells perfectly balanced in 4-6mv range but now 20-30mv. If your pack 60 mv imbalance is 1 dead cell, than I could have no dead but weak cell?! I...

Hello @lgli I see your last post is 2 years old, but I have the same problem now. My HV battery imbalance has increased from 4-6 mv to 20-30mv in last month. Was your 30mv imbalance a problem for your HV battery in long term? Have I to dig deeper and let my HV battery check for some fault...

Hello. first of all marry Christmas and happy new year to you. @wk057 I have red many threads you wrote about Tesla HV batteries and I know you are expert in this segment. because of this I have a question. My 2015 70D model S 135k KM began for about a month to increase imbalance. the problem...

Hi. I did no update. No changes at all.

Hi All. I use Teslalogger about 3 month now and I'm very happy with it. But for about 2 weeks ago, it has begone, that my Tesla MS 2015 MCU won't go in sleep mode. I have tried to reboot (soft, hard) the car, changed password, but nothing seems to work. After that I have tried to suspend the...

Yes. I know this, but this is the problem, that by VIN there is no accident to see. And the person who made my SRS ECU reset, wrote to me that it looks like it was cleared before!

I have some question for the community: If I will write to my SRS eeprom cleared dump from other SRS module where the part numbers are same, will it work on my car? Do I need to redeploy the tesla firmware to make it working? what would be your suggestions? thanks

Well, I checked all connectors and they are all ok. I contacted the guy who made the reset for me and told him that it is not working. He asked me to remove pyrofuse connector and check if I get alert in the notification menu. I did it and unfortunately I get no alerts. This means that the srs...

I have TAS too but my car is 12/2015 and the air suspension is working without any problems

@M0rpH3x First of all thank you for your quick answer. I sent dump file from my SRS ECU to the Guy from ebay and he removed all crash data and sent it to me back. After that I wrote it to the eeprom and installed the ECU to its place. All connection are ok. But the 12v pyrofuse is from Mercedes...

Hello. I need help. the chrash data form SRS ECU is removed, all airbags are replaced, but the airbag light is still on! What can I do without toolbox to get the the light of? thanks in advance

Hello. I'm rebuilding my tesla model s 2015. All airbags and belts are already replaced. Also I made a reset of the airbag SRS ECU. But after installing it on it's place the airbag light is on. Can anyone help me to solve this problem? Must I make the redeployment (or new install or Updete )...

I'm interested in this soft! But I can not DM you :(

Old post here but how did you solved the problem? did you replaced the pyro fuse located from left outer side of fuse box in the front trunk?

I have one question here about tesla model 3 2020 long range. It's my brother's car and we have bought it also as selvage car! We can't bind it with the phone App. The car is always offline. Some guys here have told us, that the certs are outdated! Can anyone write me, how can I check the...

As I already mentioned, my tesla is selvage and also in Tbilisi we have no Tesla official SC. No way to have problems with tesla SC at all :) I will check the post #1510 and put it on my todo list as an option for rooting opportunity. Thanks

Thank you for your answer. I bought a salvage tesla model s 2015 on the selvage auction and it is now on the way to me. Before it comes to me, I don't really know what kind of firmware is on it. It is also interested to know how to get the patched bootloader and kernel. As i understand it is...

Hi. I'm new at this forum and sorry if my question is not in the right topic. can someone explain me how to root tesla model s 2015? I found this in internet: A Step-By-Step Guide On How To Hack Tesla And Get Root Access - Software Focus, but I can not find the script named obtain_root. what...

Unfortunately I'm not able or can't find from where I can do this :(

Hi all. For couple dais ago I bought tesla model s 2015 which had small accident and drivers and knee airbag and belt are deployed. The car is on the way to me. As I know it won't start. I have read many topics about it and as I understand Tesla model s has two of the pyro fuses: one for 12v and...
