Battery Lifecycle Monitoring Under The Framework OfIOT

In communication systems, power systems, defense systems and emergency readiness, transportation, high-speed railways, airports areas, which require twenty-four hours of uninterrupted production and service, battery has been widely used. Meanwhile, a large number of discarded batteries will destroy the ecological environment and health of human, so the battery monitor for human production and life has a very important significance. However, part of battery are the maintenance-free and fully enclosed, such as VRLA batteries, these features make the battery monitoring technology is facing new challenges, and networking technology to produce battery monitoring technology has opened up a new approach direction.RFID technology, sensing technology is applied in this dissertation based on the Internet of things (IOT) within the framework of the establishment of a fully, three-dimensional, multi-function battery monitoring system of the whole life cycle. The research results of this dissertation are outlined as following:1. Propose battery lifecycle management concepts, constructs battery lifecycle management system based on IOT, which includes six parts:production, logistics, storage, use, disposal and recycling. For each part, the establishment of appropriate management systems and Oracle databases Battery information table.2. Plan for RFID technology in battery life cycle management system, propose RFID application types, work-standards, operating frequency, the system architecture as well as its security protocol.3. In the use-online management system, a new battery internal resistance detection algorithm is proposed. The algorithm by two resistance data (the same set of batteries, different time periods) consolidated different percentages, get the security situation to determine the battery threshold by comparing the threshold value set in advance, and ultimately determine the security status of the battery.
