Hi everyone,

I want to configure the fuel gauge to measure temperature using the NTC thermistor installed on a Varta LPP 503759 8HH battery. As I understand, for a more precise mesurements, I need to configure *Temp Model* parameters, like **Ext a Coef N**, **Ext type1/2 Coef N**, **Ext Min AD and Ext Max Temp**. So far, I've found this thread:

e2e.ti.com/.../868181

with a link to the excel document that can calculate five **Ext a Coef N** parameters, **Ext Min AD** and **Ext Max Temp** parameters. However, it's still not clear how to obtain **Ext type1/2 Coef N parameters** of the Data Memory. Are they simply B coefficients from this excel doc? Also, should I change any **Int...** parameters, or do they refer to the internal fuel gauge temperature sensor and I shouldn't change them at all?

Regards,

Pavels
