What is instantaneous current conversion (ICC)?
In the device's Instantaneous Current Conversion (ICC) mode, the ADC generates a 13-bit signed result in about 3.9 ms, providing a method to measure battery voltage and discharge current at about the same time when calculating impedance.
How long does it take a battery to fully discharge?
In general you might expect this number to be something like 1/5 or 1/10 of the C rate, meaning a 5 hour or 10 hour time to fully discharge. Maximum continuous discharge current sounds like what is the maximum drain current that will remain safe on the battery without "abusing" it and thereby shortening battery life.
What is the discharge voltage of a lithium ion battery?
During the battery discharging period, the Li-Ion battery voltage discharges from 4.2 V at fully charged state to 3.0 V at the end of discharge voltage (EDV). The battery voltage reaches the EDV earlier under higher discharge current than under lower discharge current due to the battery internal impedance effect.
Why does battery voltage reaches the EDV earlier?
The battery voltage reaches the EDV earlier under higher discharge current than under lower discharge current due to the battery internal impedance effect. This means that the useable battery capacity is smaller at the higher discharge rate than at the lower discharge rate.
What happens when a constant current is discharged?
When discharging at a constant current, the state of charge Q (defined here as the integral of Galvanic current I>0) increases linearly with time. Equation (3) also tells us the time-dependent external resistance required to maintain constant current discharge.
How does a battery management system calculate SoC?
The current-based method tracks the change in charge remaining in the battery by measuring discharge and charge currents. In this method, called coulomb counting, the battery management system estimates SOC by calculating net increase and decrease in charge based on current measurement.
