Hi Miggols99 There are a number of curious things about the two screenshots. Look at the last line that shows the capacity and the Ah remaining. The car computes the SoC by dividing the Ah remaining by the capacity and multiplying by 100. To find the Ah remaining the car sets the Ah remaining...

Hi KommyKT Thanks very much for this information. Cheers David

In my post above on conversions I show the battery 100% capacity in Ah as PID 374 byte(7)/2. (PID 374 also contains the SoC.) This conversion gives a value for the capacity with a resolution of 0.5 Ah. However CaniOn and EVBatMon both report the battery Ah capacity with a resolution of 0.1 Ah. I...

Hi KommyKT Thanks for checking my conversions! Note that the equation in my post is (byte(3)*256+byte(4))*256 + byte(5) which is mathematically the same as yours. As mentioned in the notes I too am uncertain about this being the outside temperature. However it is the temperature that I have...

Hi Yes very interesting results! The most recent dealer measurement of the my battery showed 41 Ah while the car showed 38.4. The OBDZero measurement agreed with the car not the dealer. This was in January of this year. I believe the reason for some of the difference is that the dealer...

Hi Miggols99 I'm also sorry to hear of your problems with the car. OBDZero is my app and I would very much like to look at the text files. Can you send a link to them. You can also send a zip to my email [email protected]. However your battery capacity is similar to other cars of the same...

Hi JoeS I've tested the OBDLink LX and it also works with OBDZero.

Hi Fitzion To supplement kirq4e comments, I would never drain the battery empty. This could be as damaging as storing the car with a fully charged battery. The lowest I have every gone is 8%. The next problem is that the kWh capacity isn't as important as the Ah. The kWh capacity varies quite a...

Hi kirq4e Thanks for your kind words about my app. Yes please send the txt files. I would very much like to see them. Your battery capacity is decreasing faster than I would expect. For 1 year and 10,000 km I would expect a drop of about 2 Ah. The 5 Ah difference between the best and the worst...

This graph shows a slow charge with 2 changes in the car’s battery 100% capacity estimate. I have search my data and I have only found 1 time when the car’s estimate may have changed when the car wasn’t slow charging. The capacity estimate does not change while rapid charging. The steps in...

This is a screen shot from the OBDZero app. It shows the capacity of each cell in the battery. This screen is available when an OBDZero capacity 1 or capacity 2 measurement has been performed. A capacity 2 measurement is more accurate than a capacity 1 measurement however a capacity 1...

This photo shows the dongles and the phones I have just tested. The phones are a Sony running android 8.1.0 and a Huawei running Android 4.3. This is the earliest version I've tested. Both phones connected with all the dongles. Below the phones are the dongles in order of quality from left to...

Hi JoeS OBDZero has worked with the OBDLink LX earlier. I haven't checked it recently because a friend has my LX. I have tested it with most of the VGate's bluetooth dongles, they were kind enough to send samples, and they worked well. Right now I'm using VGate's vLinker FD+ and it works very...

Here is screen shot from a OBDZero user who measured his battery using the Cap2 function in the OBDZero app Note that Cap2 capacity is 36.7 Ah while the car capacity estimate is 33.5 Ah. That the car estimate is less than the measured capacity is something others have observed. For some of...

Here is a list of the PID conversions in the OBDZero app. Most of the useful conversions were found by others on this tread before I started looking. Note 0 Each PID contains 1 to 8 bytes. The first byte is numbered 1 and the last byte is numbered 8. When on/off information is code it is...

All most all of them were found by jjlink, garygid, priusfan, plaes, dax, cristi, and kiev before I started looking.

Here is a complete list of the raw data used in OBDZero. You can also find this list in the OBDZero user manual. Download it from odbzero.dk The list is in the manual's Annex 2. Note that in this case the bytes are numbered from 0 to 7 not 1 to 8. Bits are number by their positional value i.e...

You asked if the author of OBDZero knows the bytes that hold the cap voltage. I'm the authors but I'm not sure what the cap voltage is. Here are 6 bytes that might help Charger DC voltage PID 389 byte 1 (of bytes 1 to 8) volts = 2*(byte1 + 0.5) Charger DC current PID 389 byte 3 amps = byte3 /...

Thanks for the positive feed back. Your question is a good one. We have two CZeros both from 2012. The one above has 120,000km while the other has only 30,000 km. Its battery capacity is still 38.5 Ah. When I do charge the cars I always charge to 100% but I wait as long as I can before charging...
