Novel Battery Charging Method using Hydrogen and Oxygen Gas Release Condition for Lead Acid Battery

This paper presents the study of lead acid battery for charging process using Hydrogen (H) and Oxygen (O2) gas release condition. The battery of 12V/100 Ah is selected to study from the purposed. The battery charging methodology is combined from the basically charging with constant current, constant voltage and gas analysis method for finding fully charging condition. The measurement data from the charging process show gas leases with relate the H and O2 gas varies from the battery voltage. The O2 and H gas release can be defined into 2 sections. The second section the O2 gas release has high changed in more than H gas release that point the H gas will be linearized trend. Theses point of the second section can define the fully charging process of the LA battery with 15.5 V of battery voltage. Therefore, this method can be defined as maximum voltage for charging the LA battery and adapted in the future.
