"Make it look" are the operational words, when if fact it is the opposite. Your software lies to you when it still gives 100%, ours lies to us when it shows SOH drop every day.Wow it makes it look like LFP really suck my MNC with 5300 miles (8529km) is still 100%
Mine is not like yours, I've removed my vin and identifier.
Assuming I have my ZS much longer, being in Aus, what OBD / Software combo are you using?Only just saw your attachment. The measured values line up perfectly with my prediction: 22/12/23 to 15/1/23 are 24 days. Calculated decline in SOH: 24 * 0.0104% = 0.25%. Actual decline in SOH: 96.82% - 96.57% = 0.25%.
I assume you set the day you go the car to 100%, but didn't actually check SOH back then?
My calculation would go: 96.57% is a loss of 3.43%, equal to 330 days of linear decline. I'd put the production day of you battery pack at 19/02/2022.
Do you have a sticker on the driver's side door of your car, with year and month on it? That's when it rolled out of the factory. Battery pack would have been made some days or weeks or even months before that.
@MoDolph Edited - took a little to understand that chart. So that's looking at decline in capacity for a battery stored at a given SOC. Great data, certainly supports my argument that even LFP should not be routinely charged to 100%. Surprised to see how well it supposedly worked being stored at very low SOCs, that's contrary to data I had seen before that saw quite some damage caused by SOC below 20%.
I agree, this will be interesting, hoping that a few people have data. @lusitano posted some data, and it seems to align very well with my predictions, despite taking place at a very different SOH, their car is already below 96%, while my analysis was around 99%.
If you have had yours longer it would be the Mk1, previous model with NMC battery. This discussion thread would not apply.Assuming I have my ZS much longer, being in Aus, what OBD / Software combo are you using?
Hi, what I meant is if I kept the ZS much longer - if you look through the menagerie of issues plaguing the ZS I picked up at the beginning of this year, it is looking like the car may become a reject. The car itself was manufactured September 22.If you have had yours longer it would be the Mk1, previous model with NMC battery. This discussion thread would not apply.
You can still read out information the same way.
For occasional use: ELM327 OBDII dongle that connects via Bluetooth with the eZS Android app
For constant monitoring: OVMS
Dongles are cheap on eBay, i.e.: Bluetooth OBD2 ELM327 Car Scanner IOS & Android Diagnostic Auto Scan Tool OBDII | eBay
Same at car stores, or from Jaycar will cost multiple times the price.
