Description

technical field [0001] The invention relates to the technical field of battery monitoring, in particular to a device for monitoring storage batteries. Background technique [0002] At present, there are many battery manufacturers in my country, mainly producing lead-acid batteries, and the industry competition pattern presents a polarized situation. Small-scale production enterprises have weak research and development capabilities, low product technology content, and a production environment that is not conducive to quality control. Stable, belonging to high-end market competitors, whose competition focuses on product performance, reliability, and recognition from downstream customers, and the market competition is orderly. Generally speaking, the battery industry is a fully competitive industry with a high degree of marketization, and the market concentration will gradually increase in the future. [0003] In 2012, the output of lead-acid batteries was 175 million KVAH, a...
