I'm not a local, but I'm charging here right now. These chargers appear to be in the valet parking area, but no one tried to stop me from driving in. Maybe I'm first to use this location.
This SC is listed in the Nav as Temporary Closure. I stopped by tonight and the palleted Urban chargers looked the same as before, but were nonfunctional. I found no evidence of replacements in the immediate area.
Your screenshot shows Nominal Full Pack at 70.8 kWh. It is generally accepted that 75's came new around 72.6 kWh. So you're degraded 2.5%, which is good. For comparison, my 2016 S75 has been around 4.8% for quite a while (now 35K miles.)
@Darren S
Could you check the raw log when at 100% SoC and look at message 0x338? The second half of the message should be either 22016464 (in hex) or 21016464, but I can't tell which? I think we all expect 2201 (290), but it sure looks like 2101 (289) from your data.
Has anyone ever seen documentary evidence (photos, screenshots, etc.) of a car shutting down right on cue when the dashboard hits 0 miles and the BMS shows 3.5 or 4 kWh nominal remaining capacity? I haven't. But I've seen plenty of evidence of that not happening. I've posted some of it, and I've...
Indeed you probably can. The only adapters in question are the cheap ELM327 Bluetooth. The "more expensive, highly recommended" OBDLink MX/LX are not involved, and the BT Low Energy are not supported by the app. If you have one that qualifies (or several is even better) here is how to test them...
Those filters were off the top of my head; they were not meant to be meaningful. However, they did allow the correct messages through after the atsp0. The reason 368 was so common was that it is a 10 Hz message, while the other three (328, 338 and 378) are 1 Hz messages. I received 100% of all...
See if this BT Terminal output provides any useful insights.
I'm not sure what you mean by a LONG time, but it looks like about 0.25 seconds (actually even less). Besides, if your mask and filter are sufficiently strict, it keeps the extra traffic out of the buffer, at least for a while. This...
I've got a problem using the app with a cheap ELM327 clone (ver 2.1, using BT Classic), but I think you can help with a minor change. See the following Raw Log.
As you can see, the mask and filter are not having any effect. After recreating the condition using a BT Terminal app, I determined...
The "proof" is that I did the experiment I linked to yesterday more than once. In fact, on about half a dozen occasions over several months, I got results more or less the same. Each time, I pulled between 3 and 4 kWh out of the battery after the dashboard said zero remaining rated miles. There...
Nominal capacity when full and nominal capacity remaining (from the BMS) do not include the "anti-bricking buffer," which the car will prevent you from entering. However, they do include an "anti-run out of gas" buffer of 3.8 Kwh that is not included in rated miles or SoC% shown on the...
@wk057
In fact, you have it exactly backwards. A well calibrated BMS with a well calibrated current shunt will always result in energy still available when you hit zero rated miles.
Now that I have your attention, let's be sure we are talking about the same things. First, I assume by "zero...
Please just try the 50% charge test I suggested next time it is convenient. It is very easy and will go a long way to proving who is right. I'll try not to sound too cocky, but I really don't have much doubt about what you will find.
Preview of coming attractions: I am just about certain that...
CAN ID 0x382 reports energyBuffer in kWh, not percent (see page 8 here). I suspect you had driven 1 to 1.5 miles after the zero level before you took that screenshot. Here is a easy way to see what your BMS SoC % would be at the zero level without actually driving that low again:
Set the charge...
What are you using to get the canbus data?
I use TM-Spy and I am not aware of any CAN messages that include a gross pack capacity (that includes a truly unusable portion). The TM-Spy main screen shows a pack capacity when full, but all of that is usable, albeit several kWhs are after the UI...
Two unrelated factors explain how EPA's 340 Wh/mi becomes ~270 Wh consumed per rated mile used on the dashboard. First, EPA's testing measures recharging at the power meter (what you pay the power company for). Tesla computes power consumption from the battery. Charging is only 80-85% efficient...
To OP: Sounds like you have the car set to Ideal Miles instead of Rated Miles. Check under Settings / Units & Format / Energy & Charging on the Controls page of the touchscreen.
@apacheguy I agree with you, but I can't tell if you agree or disagree with me. Maybe just a question of semantics. When I say true zero, I mean the predicted point of forced shutdown, not zero volts or complete discharge.
Accessing the diagnostic port in cars with the console is discussed starting here (with pictures). Not quite as easy as moving the cubby, but it is doable.
The scaling factors came from here.
You say you are interfaced over UART using an mbed microcontroller. I sure wish I knew what that meant, but I will suggest this possibility. You are reading the registers and applying the scaling factor. Perhaps the BMS reads the register and converts that...
Please post a photo showing 260 Wh/mi consumption using more rated miles than actually driven, because that can't be right if the drive is all at once, as long as 50 miles, and right after charging. Your consumption in a S60D should be around 265-270 Wh per rated mile. It is less than the 285...
The delta is that TM-Spy reports SoC using true zero as 0%, while the dash shows SoC using the top of the below 0 rated miles buffer as 0%. The buffer is about 3.8 kWh. See my post here for a screenshot of TM-Spy when the dash is showing 0%.
The pack balance of 7 mV at that SoC looks good. At...
Try running the test again when you have a long trip and can do all the consumption in the shortest possible time. Having a shortage of 5 or 6 kWh seems reasonable, but 12 kWh is way too much. BTW, what is your rated KM at 100% state of charge?
How does that compare with getting root access? Can you get shell access without disassembling the dash any more than needed to access the Tesla Diagnostic Connector that TM-Spy uses? (behind the bottom of the touchscreen)
I have not seen anyone else with a refreshed 60/75 that can get peak supercharging above 100 kW. Next time it is convenient, could you check the touchscreen or mobile app when supercharging from a low SoC and see if it agrees with your TeslaFi numbers? A screenshot would be great. I'm wondering...
There have been many firmware versions since 5.x, and therefore many opportunities for Tesla to put it back. My guess is they got tired of people having a shutdown while still showing a few miles of range remaining, and then arguing that Tesla should pay for the tow.
Getting and using TM-Spy is discussed here and also here (including the link to expose it on Google Play).
The idea that you might have a bad module also occurred to me. I would think the car would recognize it and report to Tesla HQ and even on the car's displays, but I have no actual...
Yes, that is what I'm saying (all numbers approximate, not exact) with one BIG caveat: I don't know that the classic S60 uses the same 3.8 usable buffer that the refreshed 60/75 does (or at least mine). The differential between your Wh/rated km while driving versus on the graph is about right...
I think (almost) everyone on this thread interprets "run to zero" as "run to zero miles" (or km) on the instrument panel.
If the pack is taken to zero volts, or whatever qualifies as 0 kWh of total remaining capacity, the pack will be ruined. The car won't let you get anywhere near that point...
It means that only 95% of your usable kWh are above 0km. 5% is in the below zero zone. This comes from 178 Wh/rated km actually seen while driving divided by 188Wh/rated km shown on the graph. In my car (refreshed 60/75) 5.3% is below zero. See this post for more information.
Since you have no...
Here's how I get the kWh counter by charging category from 0x0302 using TM-Spy (almost certainly not the most efficient/elegant way, but it works for me.)
Go to Settings and select Trace ELM at the bottom. Also, set the app to display the default screen if necessary (like you wanted to check...
First, I highly doubt -17% would be achievable. Even the -8% in my post assumed I could drive 5 more miles, which I doubt. I was at about -6.3% when I decided it was time to quit and put the car on the charger. Regarding your question about calibration of the BMS, theoretically it should be a...
