Separate names with a comma.
Open inverter might not like the roadster's low inductance motor, though we did get the Rinehart motion PM250DZ working with it (with some custom...
Ive used an PM250 - 250kW and had RMS tune a roadster motor for it.
Again spouting stuffs without facts to back them.. you just join today and started this thread and is spreading false info...
You have no real data to back up your illogical conclusions, your simply trolling now.
Nice that's it out, and you have HV experience, you can take the front cover off, and you then can measure each sheet voltages (there is 11 of...
Wow lots of misinformation here... others will correct you. The BMS will handle a lot, but simply put the End user can control cycle count, SOC,...
How much time has passed since it was disconnected? Is the ESS out of the car?
Yes in my view, note I have tested model 3/S, Roadster etc.. cells and have built BMS systems.
If it were only so simple! Advanced users might want to extend battery cycle life by keeping it at a lower SOC over time.
Wished this board has fuses on each trace, as there was one sheet that i know of that had shorted sense wires and caused all the fuses on it to...
Be careful trying to charge low voltage ESS sheets, don't do it anywhere near the things you care about as it can go up in flames.
Look at vin and this post Decoding Tesla Roadster VINs
I got the email today. Same
sounds like loss of 12v power. Agreed with PV-EV check and see if your coolant and pump are running.
Had my intern design a BMS (runs on ESP32 "WeMos" board and "Link Node" board) that connects to the Model S modules and talks to the Tesla BMB's....
btw on a USB drive that's larger than 2 gigs, you can use windows "Disk Management" find your USB stick, delete all partitions on it. then create...
Pm me i might have temp fix for you.
Charge to full, let it sit and make sure it's keeps balancing and keep a log tracking of Bricks Max/Min SOC after each charge, hope balancing can...
Came marked from Tesla, the ones circled are ones that failed QA I believe, as there are two ultrasonic weld marks present vs the normal one.
Correct :)
[ATTACH] Good eye, how about this one :)
In case someone was curious. [ATTACH]
Got to have that in any commercial battery product with normal lithium chemistries. My question would be how does it work in negatives temps,...
I haven't ever done a range charge on this pack, let me start an range charge now. As people keep asking for an 100% range charge.
I'm out of space so listing roadster #164 up for sale. Things that stand out for me are the super low miles (~3400) and microfiber cloth seat...
Listing roadster #164 soon, figured I post it here first. Things that stand out for me are the low miles and microfiber cloth seat option. Car...
should share the stl file as ZIP (or just remove the extension), as I like to make a print of it.
I still have this problem with Henry's CAN, on my Clipper Creek.
On the 2.0, I just disconnected the 12v battery and left it disconnected and I never got an error message. So i left it that way until Tesla did...
Temps seem fine.
I meant to say to aim the two closest mid level vents to my upper legs, to the point they are start restricting air flow. I then aim the two...
I noticed the lower floor vents are not very powerful, and in the debug HVAC menu seems to support that theory. As I see some heater element...
Note the green 2.5 sport isn't my car, so I just update the ad when the owner asked me too. X.l.r.8 I'll be sticking around as I still have my...
Oh it's also an Sport model too, I forgot as the decal is missing.
I don't see why Tesla will not help, they had a change of policy about a month ago to allow servicing of all rebuilt titles.
Ad updated. Thanks TEG!
I'll grab vin and update ad about the base rims
I mean when your power limited. Also set alerts to debug mode.
goto service menu: ESS: V&T: and see what min and max brick temperature is.
I got an good ESS sheet from Gruber. I have bought an ESS battery sheet from them, worked fine.
I didn't repost the craigslist ad as I'm too lazy, I'm in the progress of upgrading the wheels to black 2.5 sport fan blade rims.
When I was talking about HVAC I meant the HVAC box itself, yes easy to service, but more expensive to replace if it fails than pump or PEM fan....
Less efficient doesn't necessary mean less MTBF of all the components in the ESS. For example less efficient inductor(s) does generate more heat...
For my usage, I connect up an 240v charger to get the AC to kick on and cool down ESS (if the pack is warm), then after the pack is cooled down, I...
Yep that's me.
Keep an eye on SOC Min/Max, see if over time if it gets worse/same/better.
Min of 75% and Max of 88%, yeah you need to pull your logs and see which ones are have the lowest voltage, highest voltage at the end of a charge...
Pull logs on USB thumb drive open with excel, or enter service menu, look at ESS/SOC menu see brick Min/Max/Ave. Guessing you have a brick that...
Friend having weird loud ting noises, anyone have any ideas? [MEDIA]
I would use key pin code to get to service menu and go to ESS-->V&T--> and look what is voltage of MinBrick, guessing it's loose rivet on sense wire.
