Description

technical field [0001] The invention relates to a lead-acid battery, in particular to a detection and repair method and system for a lead-acid battery. Background technique [0002] Lead-acid battery is a widely used power source, and its design service life is generally 10 years, but the service life of lead-acid battery in actual application is only 1-2 years. The main reason for this phenomenon is that lead-acid batteries often have problems of poor use and maintenance during use, such as frequent undercharging, untimely charging, and long-term transitional discharge and charging. These problems lead to the gradual formation of a hard and poorly conductive coarse-grained lead sulfate on the battery plates, a phenomenon known as sulfidation. These coarse crystalline lead sulfates block the gaps on the battery plate, making it difficult for the electrolyte to penetrate and increasing the internal resistance, which eventually makes the lead-acid battery unusable.
