Three common SoC monitoring methods – voltage correlation, current integration, and Impedance Track are discussed. State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature.
Load testing is one of the most accurate ways to check the health of a lead-acid battery. It measures the battery’s ability to deliver current under a load. This test can help determine if the battery is capable of supplying the required current for a particular application. To perform a load test, you will need a load tester.
In the field of battery state estimation, the KF and its variants are commonly used for online SOC estimation of lead-acid batteries [, , , , ]. The common process includes five steps. First, a battery equivalent circuit model, which is often the same as the model shown in Fig. 5, is built.
To perform the load test, follow these steps: Charge the battery fully before testing. Connect the load tester to the battery terminals. Set the load tester to the appropriate load for the battery. Apply the load for 10 to 15 seconds. Record the voltage reading. Compare the voltage reading to the manufacturer’s specifications.
Lead acid batteries are batteries for solar panel systems that use Lead Acid as the chemical. Lead acid batteries are strongly recommended using the constant current constant voltage (CCCV) charging method. The battery used in this test has a capacity of 12V 7.2 Ah according to the previous converter design.
In addition, in almost all of these studies, the results demonstrate that the SOH and the resistance (or conductance, which is the reciprocal of resistance) of the lead-acid batteries follow an almost linear relationship, and that the resistance can be used as a powerful tool to estimate the SOH.
