How To Calculate Battery Percentage From Voltage. Ah Wh C-rate. I was responsible for assessing the fuel gauging algorithm in a new smartphone model.
I was responsible for assessing the fuel gauging algorithm in a new smartphone model. Battery capacity formula. Knowing the hour rate of your battery its specified capacity and Peukerts exponent.
But problem is when i measure battery volatge it get sometime 58 sometime 70 means its variation in battery percentage.
I cant find mathematical functions describing the curves. It can also be seen that a loaded voltage of 25 volt will immediately jump up to 33 volt when the load is removed and slowly reach 34 volt after 1 hour. The above equation will help you on how to calculate mAh. I can answer question 2 and the question in your title - most mobile devices use Lithium ion batteries and the raw voltage of the battery has a very non-linear relationship with how much capacity it has left ie.
