Budget Battery Capacity Readout

It did work as you suggested, but the dashboard values were all too large. I went into individual entries on the first three dashboards and corrected everything. Here is an example of how dashboard #3 looked before I modified it:

 

I haven't purchased a device yet but I am extremely interested in knowing when the brake lights activate. Hopefully this new sensor makes that possible. I have some evidence that the brake lights often come on unnecessarily when using ACC and this would help confirm my suspicions.

 

The brake lights are activated any time the brake pedal is pressed, but the brake lights can also be activated by heavy enough slowing in ACC. I have a theory that ACC never uses the friction brakes, only regen, I suspect that only CMBS (Collision Mitigation Braking System) uses the friction brakes. I'm not sure of that but maybe this sensor will help answer that question, i.e. my theory would be confirmed if this sensor never seems to activate in ACC even when strong regen occurs.

But yes a sensor related specifically to the brake lights would be nice also if there is one available.

 

Got my vgate pro today - how do I import the backup in iOS??? I can only restore backups I made within the app.

thanks

 

First off, thanks a bunch for getting this whole setup and process figured out with a few others in the forum.
Yes, I have the same issue with the fonts (pic attached) on my Android phone. I think we need to adjust it down
for folks using phones. Minor issue really compared to the work you have put in. Thanks again !!

Here is my actual data (already updated the google doc)
Build - 7/18
Bought - 9/18 (Within a week of car arriving at the lot)
Model - Base
Mileage - 21888 miles
EV driving - 90%
Battery Capacity - 47.44 Ah (quite low compared to others)

I scanned the spreadsheet and I think the main factors influencing the capacity are
1) % of EV driving
2) Ambient temperature

Being in the desert southwest, I suspect my battery has degraded more than others in the colder northern states/canada
for similar mileage and EV % driving.

 

@lanb , I am close to you in mileage (approaching 20k). I have a little over 60% EV compared to your 90%. Both cars are essentially the same age. Alabama is probably closer to your temps than our northern car owners, but probably not quite as hot as in the desert southwest. My Cap reading was 51.9 Ah. I suspect that I am helped somewhat by the lower EV usage and I always park in a cool place to charge (either the lowest level of a parking deck at work which stays pretty cool - lowest level is essentially below ground or in my basement garage which is always pretty cool as well - always in the 70s F). I also try not to leave my car charged at 100% too much of the time. When I can remember to catch it, I will stop charging at 90-95% if I don't think I'll need all the battery the next time I drive it. I really don't think that helps much to add to the life of the battery, but I thought I'd mention it.

 

Not sure if they are compatible as I can’t even figure out how to point to the the restore file (ie there is no “browse” option).

i have emailed the developer

 

ok, just tested in Android 48.9.

bought in August 2019. 29k kms, maybe 25k in EV mode. battery pretty much fully charged on L2 and discharged 6 times a week.
Seems like it's excessively degrading, no?

we are in QC, so uses a.lot.for.heating in winter, but we dont have a lot.of.hot days that would be bad for.the battery

 

So the warranty kicks in at 30% loss, which is at 38.5? Mine is leased for 4 years, so I will see how it goes over the next couple of years and decide if it will kick the bucket before or after the warranty expires to see if I keep it or return it.

12% for 1.5 years seems a lot

 

hmm, I thought it was more like 70%, not 66. We will see how it degrades over the next 2 years, as I don’t anticipate the usage pattern to change much.

Also, my car was a floor model and obviously they didn’t give me the capacity at delivery- the checklist they gave is probably the generic one they use for all cars. So it might have already been down as I doubt they maintained the battery at 40% when unused.

aren’t the other manufacturers at 70%?

 

They were large like that after the initial restore. Importing the cell voltages made no difference.

 

Agree. I think your 60% EV equates to less charging cycles and 70 F is our winter highs
The million dollar question for all of us, will the degrade slow down as the battery ages or if it will continue
at the same pace. I plan to monitor by taking monthly or quarterly readings.

 

See my post above you. The higher % of EV driving equates to more charging cycles which I think is the #1 reason for
battery degradation.
