6 FAQs about [Battery leakage current principle]

Can battery leakage current be measured by a battery simulator?

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).

How do you measure a battery terminal voltage change?

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.

What is the leakage current of a lithium coin battery?

When the rechargeable Lithium coin battery is employed as the storage component for indoor energy harvesting, the leakage current of the battery cannot be ignored, especially in ultra-low-power applications. The leakage current of the Lithium coin battery is commonly believed in the low μA range. However the exact value is unknown.

What happens if a charge current is larger than a leakage current?

When the applied charge current is larger than the leakage current, a positive sign (terminal voltage increase) can be observed. Otherwise a negative sign appears. By gradually changing the charge current using the successive approximation search algorithm, the leakage current will finally converge to the applied charge current.

How much battery leakage is a trickle charge?

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.)
