Automobile lithium battery dynamic charging protection system based on knowledge graph and 5G technology

Abstract

According to the automobile lithium battery dynamic charging protection system based on the knowledge graph and the 5G technology, the charging information is input into the self-query knowledge graph through the self-query knowledge graph, the second charging threshold voltage can be quickly queried and obtained, and the first charging threshold voltage can be obtained in combination with the loss empirical function. Moreover, the association relationship of the knowledge graph is more accurate than the conventional corresponding relationship, so that the second charging threshold voltage is more accurate; the association relationship of the knowledge graph comprises the association between the charging information entities, due to the change of the charging information, the second charging threshold voltage and the first charging threshold voltage can be dynamically adjusted along with the dynamic change; the accuracy is higher, and the influence of the loss condition of the battery can be eliminated through the knowledge graph; and meanwhile, the knowledge graph is coupled by applying the 5G technology, so that the query efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of battery charging dynamic protection, in particular to an automotive lithium battery dynamic charging protection system based on knowledge graph and 5G technology. Background technique [0002] At present, batteries (such as mobile phone lithium batteries, automobile lithium batteries, lead-acid batteries, etc.) generally have charging protection functions and fast charging functions, but the current charging scheme generally uses the fast charging function to charge the battery to about 80%, and then uses slow charging. The way of charging is "charging protection", which can protect the rechargeable battery. [0003] However, on the one hand, the above functions only protect the rechargeable battery relatively rigidly, without considering the loss of the rechargeable battery itself, and the charging protection error is large, resulting in the inability to effectively charge the battery. On the other hand,...

[0003] However, on the one hand, the above functions only protect the rechargeable battery relatively rigidly, without considering the loss of the rechargeable battery itself, and the charging protection error is large, resulting in the inability to effectively charge the battery. On the other hand, for automotive lithium batteries, it is necessary Charging piles are used for charging, and this method increases the burden of charging piles, especially for the popular charging piles, which also have power storage functions. When charging the lithium battery of a car, the charging voltage needs to be adjusted at any time, and adjusted at any time The charging power will undoubtedly cause damage to the charging pile itself, so the current "charging protection" is not perfect, and the charging protection for automotive lithium batteries only transfers the risk from the consumer to the charging pile manufacturer, and does not fundamentally solve the problem of charging protection.
