Battery Remaining Capacity
I am writing an application to find the current battery capacity in the driver level.
My board has Li_Ion battery.
I can get the following parameters from the battery driver:
I have to find out the remaining battery capacity with the above params.
I read some article which says we have to consider 1)temperature derate factor and 2)depth of discharge to calculate the capacity with accuracy.
Please help me in this regard.
I have gone through the posts made in this forum. All the posts are
discussing about /proc/acpi filesystems.
But my case is different.
Maybe you could specify in what regards your case is different? I can't help you, as I am not much of a programmer, but that information might help some one who can to give you more specific help.
I have to find out the remaining battery capacity without /proc/acpi file system.
I have to use the following parameters to calculate the battery capacity.
I read in an article to find the current battery energy in Watt-Hours.
E = C * Vavg * (tempdefactor/100) * (depthdischarge/100)
tempdefactor -> Temperate derating factor
depth discharge -> depth of discharge.
Can i use this formula to calculate the current available energy of a battery?
If so, what value i can use for tempdefacor and depthdischarge?
Is there any spec or tables to find out these values based on temperature and ageing?
Hope am not confusing you.
