Research on the repair technology of remote lead-acid battery in cloud

With the rapid development of energy storage equipment in power companies, batteries in power room energy storage equipment are developing towards a wide distribution and large quantity, which poses new challenges to the economy, sustainability, flexibility, and reliability of power energy storage systems. Traditional manual battery maintenance methods have low efficiency and high labor costs. Most of them still use offline maintenance methods, which is difficult to meet the development needs of energy storage equipment. In this study, we proposed a solution that combines state monitoring, dynamic balancing, sleep technology, and online repair technology of unit batteries. We summarized the advantages and disadvantages of this solution and proposed improvement methods.
