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.
The following formula is used to calculate a leakage current. To calculate the leakage current, multiply the voltage by 377, then multiply the capacitance by the result. What is a leakage current? Definition: Leakage current is defined as any amount of current traveling along an unwanted path in a circuit. How to calculate leakage current?
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).
The total ideal leakage current is 88.88uA. In the case where all the Y capacitance deviations are equal to zero, the Patient leakage current can meet the requirement of less than 100uA. A Pspice simulation circuit for Leakage Current measurement is built in Figure 5 to verify the above calculation result.
At the 264Vac input, the ideal fundamental leakage current of the power supply is 76.97uA and the third harmonic leakage current is 15.84uA. The total ideal leakage current is 88.88uA. In the case where all the Y capacitance deviations are equal to zero, the Patient leakage current can meet the requirement of less than 100uA.
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.
