Leakage current can be measured in at least two ways: Apply a DC voltage to a capacitor and measure the current required to maintain that voltage. Charge a capacitor to a fixed voltage, then open the circuit on the capacitor and measure the voltage change during self-discharge.
The leakage current of a battery can be measured by the battery test equipment. However, existing battery simulators are not accurate for small capacity Lithium coin batteries (such as 10 μA measurement accuracy in the dynamic model battery simulator of Keithley 2281S).
An experimental method to measure leakage current by applying a known charge current in μAs to a stabilized post-charge battery to observe the sign of the battery terminal voltage change is proposed. When the applied charge current is larger than the leakage current, a positive sign (terminal voltage increase) can be observed.
Therefore the leakage current of the Lithium coin battery should be acquired in μA level to precisely estimate the state of charge (SOC) of the battery for utmost using harvested energy in indoor applications. The leakage current of a battery can be measured by the battery test equipment.
Direct potentiostatic measurement of capacitor leakage current is quite challenging. The test must apply a DC potential to capacitor under test, and measure extremely small currents. Typically, capacitor charging currents are in ampères and leakage currents are in microampères, a range of 10 6.
Bottom: applied charge current (I charge) pattern. The trickle charge state happens in blue current pattern periods, so the battery leakage is 1.0 μA. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
