Hello,

I noticed that my BMV is calculating a too low SOC value (yes, it has been days since 100% charge reset), so I thought my currently set 1.05 Peuker's coefficient is too small for Tesla batteries. I adjusted it to 1.02 and to my surprise SOC instantly went **down** (?!) from 28% to 21%. Adjusted it back to 1.05 - SOC went back **up** to 28% again.

- To my understanding, adjusting Peuker's closer to 1.0 should
**increase SOC**not decrease it, shoudn't it? - Shouldn't the Peuker's coeff. be applied only during real-time? How is it incalculated into the SOC? Is BMV saving all historical Ampers that have flown through it since last 100% (I'd think that's highly unlikely)? If not, what's the formula? Consider that there's no temp. compensation, etc.
- Is there a situation where Peuker's coeff. of, say, 1.02 not only decreases capacity, but can increase it?
- Now I have set it to 1.0 to see how the SOC is being calculated without it. What params to use in BMV to make SOC calculation trivial as such (i.e. without no Peuker's, temperature, efficiency, etc. magic):

(Consumed AmpHours / Battery Capacity) - 1

If I do this calculation I get 30% SOC, which is closer to reality than currently reported 21% with Peuker's 1.0 and charge efficiency 98%.

Thank you for your insights!
