Worried or Not? First battery/charge issue and 1st logs

[Matteni]

I purchased my roadster 1.5 back in January and am loving it.

I have put many mods including preventative PEM work.

I usually only charge 110V 15A unless I need a cooling cycle 240V 16A.

Usually Ideal range in the low 180's

The last 2 times I have changed my ideal range was in the 160's and now 159. Previously lowest was 179.

I was concerned something happening so finally pulled my log files to see what was going on.

I also figured out I was having a common problem with the GFI on the standard 110V (was tripping).

So when I pulled the logs is seems the CAC is consistent? Fine?

Just put a new plug and charge?

Or my ideal range was overly optimistic and this is the real range?

Or a reason to be concerned?

I drive it daily between 5-20 miles total and daily charge it always standard mode charge and have never driven it down below 50% capacity since I had it.

Would love to hear from any log or battery wiser folks.

How do I interpret this?

I doesn't seem to have a drastic drop in CAC - but why the drastic drop in ideal range?

What setting do you guys use in the DOS command line app to get the sheets and brick values?

[DeedWest]

As I have described in recent threads, many low mileage Roadsters have an unrealistic representation of their CAC due to the majority of their life spent on the charger or in storage.

Once they are driven regularly and the ESS has the chance to balance, it is extremely common to see the CAC drop. In the case you've described above, this is highly likely for a 2008 Roadster. You should see it level out at a certain point.

However, what you're seeing here reminds me of a common imbalance when charging using the 110V connector. Sometimes it will show an inaccurate reading until the car is driven for a little while. Being that there is no proven benefit to charging with 110V, have you considered or tried switching to 240V indefinitely to see if the issue persists?

Also, make sure you didn’t accidentally tap the “RANGE” button on the VDS. This makes the car display your “Estimated Range” instead of “Ideal Range”, which shows range based on the past 30 miles of driving style. Shown below -

Ideal Range

Estimated Range after clicking bottom range button.

 

[Matteni]

No I was always looking at ideal range and I do switch between 110 volt and 240 v. I used 240 v 16 amp when it's hot out and I want to initiate a cooling cycle. Otherwise I just stick with 110 v. I have another Tesla motor and battery car that shares our dryer plug on a dryer buddy.

I only drive between 5 and 20 miles a day so there's no need to charge any quicker than 110 volt.

I did experience the common ground fault interrupt problem on the old original charger and I'm going to bypass it when I get a new plug tomorrow

In the meantime the car is plugged in on 240 v 16 amp after a spirited and fun drive

There is some evidence that what you're saying is true because my car would charge to a higher ideal range but the miles would fall quickly

Tonight we went for a long drive and the miles fell much more slowly as we drove

I'll see what the charge is tomorrow and report back

Did you happen to look at the log file below? Am I reading it right to say that they're really hasn't been much lost in the last 60 days?

in the meantime I spent a couple hours installing my new rotors from titanium Dave and unboxing my visium transparent hardtop

Part of owning a roadster is kind of like life just learning to enjoy it despite the degradation that happens for everyone. It's just that I love the car so much it's easier said than done sometimes.

 

[Matteni]

Quick update

2 days ago on 110v lost 20 miles of range on a charge = 165 ideal

1 day ago on 110v lost another 10 miles of ideal range =155 miles ideal

Pulled logs and CAC didn't show dramatic difference or low brick

Lots of charging errors and GFI popped

Switched last night after 50 mile fun drive to 240v 16a

Woke up nervous this morning but it charged to 179 ideal which is what I was getting before on 240v give or take. 110v gives me an extra 4 to 6 miles

I couldn't test the 240-volt charger during the day because we share it with a dryer plug and we do a lot of laundry over the weekend.

Amazon's bringing me a replacement plug for the original 110 volt. Should have more information for posterity here in a day or two.

 

[gregd]

Is there a reason, besides the indicated few extra miles, to charge on 120v instead of 240? 240v is more efficient (less power consumed) than 120v, and as you noted, you get the benefit of letting the car use the A/C to actively cool the battery which helps with battery life. I would recommend using 240v charging as much as you can, and only use 120v if the 240v is unavailable. If your CAC hasn't changed, I wouldn't worry about the battery's health.

Regarding the dryer plug, if you haven't already, you might look for a "Dryer Buddy" to coordinate the sharing of the plug. I made my own (er, sort of...) and used it for several years until I upgraded the panel and put in a dedicated 14-50 outlet.

Couple of things.

We have the new and improved Dryer Buddy that auto switches (great family owned business/product!).

That 30 AMP dryer plug is split between my wife's electric car MB 250e with 85 miles of standard range (thank you Tesla!) and the Roadster. With the famliy all at home we find ourselves needing the dryer a lot (4 kids) and also my wife's car needing to quick charge a lot.

Also it has been a VERY mild spring/summer so I haven't needed to cool the PEM/battery (not getting into even the yellow yet after a spirited drive).

So 100v meets my needs, isn't turning on/off, allows me to save the amps for wife's car, and hasn't been needed much for cooling.

do you have ovms? Could the 8-10 miles be phantom drain from when you wake up? Did you physically see the car charge to 155 or 165 before you went to sleep?

 

[Matteni]

1) OVMS = No (I know - I know)
2) I have nightly charged every single day for months and it was always between 181-185 on 110v and 177-181 on 220v. The car said stopped charging on the VDS with 16x and then 15x so I felt something was very wrong. The first night I noticed the wall GFI tripped at some point and the 2nd night the Tesla 110v charger GFI tripped. I was aware of the fact that almost 100% of these go bad and need to be removed from the Tesla charger but didn't get around to it. The fact it seemed to show that the car had finished charging was a head fake. When I pulled and analyze the error codes I posted - they seemed charging related and so I started to put 2 and 2 together that it was the GFI and not the car battery brick/cells failing most likely. Or that dramatic swings were normal (thus posting here).
3) No I didn't (see above).

 

[jason.tv]

Here is what I think is happening; you had the same exact issue as me. Summer time is now here and the temperatures are indeed hotter and more moist in some climates than others.

I push my car hard; just like you I it's a weekend car for me. So when I drive I like to "show off" which causes in that short period of time extreme heat to be generated in the battery. Try doing this for 2-3 days straight and the 10-20 miles it needs to charge is not enough time for the heat to be released from the battery from when charging is completed.

This will cause your car to not go to sleep since the battery temperature is still above the idle temp which is the reasoning for the first question about the ovms.

So when you wake up in the morning your coolant pump was running 24/7 and never shut off after finished charging which could cause the 8-10 miles loss which you might think your car only charged to that point; which is why next question was did you physically see it charge to 15x and 16x.

So to get more in detail; I thought my car was screwed or something was wrong as well; but from pushing the car for only 10-15 miles and then returning home to charge then taking it out the next day my car was not going to sleep; the coolant pump was constantly running and would not go to sleep no matter what I did. So in the morning I already lost 8-9 miles of range; I consulted with many people which helped and gave me more knowledge about the vehicle @DeedWest .

So what probably happened with you since you are getting your ideal charging numbers again it seems like you didn't drive the car the next day or two thinking something was wrong with the car; during this time the next charge cycles reduced / exhausted the remaining heat inside the battery cells causing it to go to sleep.

You can monitor the Ambient temperatures and battery temperatures through ovms to ensure your car is reaching the idle temp for the battery to go to sleep; without this is the reasoning you thought you had a bad brick or sheet while your cac was remaining the same. The battery goes to sleep when the battery reaches 87f optimal temperature.

I would not use the 120v and only use the 240v 16A as you mentioned to reduce the heat from the battery and gives it time to exhaust the heat with multiple cycles since dialed down to 16A which you have been doing.

I think you are probably right about the 16a / 220v but I also think the GFI was part of my problem (lots of reported fails here).

I always monitor the PEM/Battery temp through VDS at end of my drive - and if even close (next to) yellow I put on the 220v/16a.

My only hesitation on days it isn't hot - is having to go into the Juicebox web interface and lower wife's to 14a (30a total) and the fact that the dryer buddy is on/off and stops and starts charging when the dryer is on.

But when it is hot or run hard - I always go to the 220v 16a so we agree on that.

I do hear the car in the garage and know when it is trying to cool via recirc/fans/etc so that all makes sense.

I still suspect that if I fix the 110v plug it will go back to normal and in this particular case that was the issue. I am going to drive gently home, setup the plug and test and report back.

Another important note - even though PEM temps may never reach the yellow zone (unless you’re tracking the vehicle or driving like @jason.tv ), the ESS temp must be under 31C for the vehicle to go to sleep. In 1.5’s this cannot be viewed unless using OVMS or visiting the Vitals page in the Diagnostic Menu. Charging on 110V also generates heat within the pack while the coolant pump is running that will not be addressed since only 240V activates cooling cycles. This almost guarantees why the car is losing miles overnight.

The sub $300 you’ll spend adding another 240V outlet in your garage will be minuscule compared to the wear & tear you’d potentially induce by sticking with 110V most of the time. It’s the best way to take care of the Roadster, regardless of how many miles are driven daily.

Great tip on the diagnostics page for vitals - thank you! Forgot about that.

As for losing miles overnight it has been very mild. I can definitely hear when the car is cooling and would know.

We agree on it would be nice to have another 240v but it is not $300 but more like $3000 (we added a sub-panel when we finished the basement and used up all our service so we are talking new/higher service total, another sub-panel, wiring to the garage, etc). I have 2 electric cars and may end up there (will end up there) but we also have 4 in college at the same time and trying to avoid major expenses for now = especially since the current setup is working so well.

We could convert dryer to electric too but the gas is on other side and that is a getting a new dryer and lines/$$$ expense as well.

The setup we have works really well for us right now. I would recommend it to others like us. It is also portable and reversible (I have Y cable and RV extension cord from Dryer Buddy to the 2 car chargers that share 30A when dryer is not running). Obviously, if you have dedicated and hard-wired that is better or if you need more for longer commutes (wife = 20 miles RT and I am 5 miles RT from work)

I know that heat is the enemy of batteries but there is heat from use and also heat internally when charging and higher and higher amps.

Now the internally generated heat is very close between the 110v 12A vs 240v 16a (by my design). It has been documented here on this forum high charging rates wear the battery out more quickly over time and I am trying to avoid that.

I chose 16A as it replaces the miles I use easily and is just enough to use the AC for battery cooling should it be required (so I will make that my default going forward for the rest of the summer as temps rise in St. Louis).

Thank you for your reasoned thoughts!

what was your error code for the GFI was part of my problem (lots of reported fails here).

If the power tripped or power went out and flicked back on the vdm will dispaly "Charging Problem"

Guessing a little from Carl's error codes since it doesn't have explinations for every one but you will see above

ERR | error code 925 6 bytes
ERR | error code 1081 6 bytes

Many times

925 = DMC HW: Common Mode Sense fault
1081 = DMC FW: Line OverFrequency warning

I could be wrong (and why I am here if I am).

Other less frequent errors are similar like

955=DMC FW: Line Sync Loss fault

I don't pretend to know for sure but if the 110v goes back to normal ideal charging after removing the GFI (known issue) then I guess since logs are not indicating other battery brick issues we can assume that was it?

ERR | error code 1081 6 bytes

Many times

925 = DMC HW: Common Mode Sense fault
1081 = DMC FW: Line OverFrequency warning

I could be wrong (and why I am here if I am).

Other less frequent errors are similar like

955=DMC FW: Line Sync Loss fault

I don't pretend to know for sure but if the 110v goes back to normal ideal charging after removing the GFI (known issue) then I guess since logs are not indicating other battery brick issues we can assume that was it?

Just from quick search it seems like your battery cells and sheets were being under voltage; which needed the 240v to balance back or give proper voltage to the cells like @DeedWest mentioned. Perhaps the sheets in your battery were being under utilized which requires more voltage for them to operate to peak efficiency.

Perhaps this is where you occurred the range loss so it balanced one of your sheets instead of letting it go bad.

You only received this error on the 110v charger I asssume. Which is putting all the power into the other components to operate which causes wear and tear over time from the duration they are powered on through 110v rather than putting the efficient required power into your battery.

On the positive side this is a good error to see imo.

Yes - those errors were on the 110v - I should have pointed that out.

Here in the US, our AC lines are 110v is 60Hz

I assumed that it got higher than 60 Hz (how much more? only Tesla would know I guess) and I attributed it to the GFI issues.

Unless we ALL get that warning in the US (most of the world uses 50 Hz). I don't know.

We will see when I remove that from the equation and pull new logs I guess.

get your car updated to 4.7.2; Some 110v outlets can do 15v; yours is doing 12v obviously not enough.

also make sure you lock the car when charging; this will signal the car to go to sleep as I read this in another post from @markwj

Another important note - even though PEM temps may never reach the yellow zone (unless you’re tracking the vehicle or driving like @jason.tv ), the ESS temp must be under 31C for the vehicle to go to sleep. In 1.5’s this cannot be viewed unless using OVMS or visiting the Vitals page in the Diagnostic Menu. Charging on 110V also generates heat within the pack while the coolant pump is running that will not be addressed since only 240V activates cooling cycles. This almost guarantees why the car is losing miles overnight.

The sub $300 you’ll spend adding another 240V outlet in your garage will be minuscule compared to the wear & tear you’d potentially induce by sticking with 110V most of the time. It’s the best way to take care of the Roadster, regardless of how many miles are driven daily.

I just did the embedding brake process for the new rotors so I got the PEM, Motor, and Battery up to Temp all three right before the Yellow Bars tonight and pulled back in the garage at 130m. It took 17 miles of charge on 240v 16A to get my battery back to optimal 87F and still charging with 17 miles remaining till it gets to 174m.

you can see how we are pretty much on par; cac 149.98

I use 240 volt. Sorry for typo. I did replace 110v plug to remove GFI and charge on a cool night so we will see in am
