一种锂电池组远程监控系统A remote monitoring system for lithium batteries

技术领域technical field

本实用新型涉及一种锂电池组远程监控系统，属电子监控技术领域。The utility model relates to a remote monitoring system for a lithium battery pack, which belongs to the technical field of electronic monitoring.

背景技术Background technique

随着锂离子电池应用领域的迅速扩张，大量单体锂电池串并联组成锂电池组，为电动汽车、储能电站、通讯基站等系统提供电源。锂离子电池技术为近几年兴起的新能源技术，怎样保证锂电池组的安全使用、零故障使用成了目前的首要难题。锂电池组管理系统虽然引入了锂电池安全管理概念，但其行为较为机械，仅在锂电池组故障发生时对锂电池组进行保护，尽管锂电池组管理系统导入了故障预警系统，但锂电池组使用者通常是非专业的，即使了解锂电池组也一般是仅略知一二，其不能通过管理系统预警信息准确的判断出应如何处理即将发生的故障或已发生的故障，而且当故障一旦发生后就很难分析或描述故障过程及原因。再次，锂电池厂商专业技术人员很难及时获得锂电池组运行信息、预警信息等，为锂电池组后续可能出现的故障恶化等很难得到及时有效控制。With the rapid expansion of the application field of lithium-ion batteries, a large number of single lithium batteries are connected in series and parallel to form a lithium battery pack to provide power for electric vehicles, energy storage power stations, communication base stations and other systems. Lithium-ion battery technology is a new energy technology that has emerged in recent years. How to ensure the safe use and zero-fault use of lithium-ion battery packs has become the primary problem at present. Although the lithium battery pack management system introduces the concept of lithium battery safety management, its behavior is relatively mechanical. It only protects the lithium battery pack when a lithium battery pack fails. Although the lithium battery pack management system introduces a fault warning system, the lithium battery Group users are usually non-professionals. Even if they know lithium battery packs, they generally only know a little bit. They cannot accurately judge how to deal with impending failures or existing failures through the early warning information of the management system. It is difficult to analyze or describe the fault process and cause after it occurs. Thirdly, it is difficult for the professional and technical personnel of lithium battery manufacturers to obtain the operation information and early warning information of lithium battery packs in time, and it is difficult to effectively control the possible failure and deterioration of lithium battery packs in a timely manner.

目前，对锂电池组的数据采集方式采用专业技术人员携带专业设备到锂电池组所在现场，通过现场测量、记录的方式进行数据采集。其存在以下缺点：At present, the data collection method for lithium battery packs uses professional technicians to carry professional equipment to the site where the lithium battery pack is located, and collect data through on-site measurement and recording. It has the following disadvantages:

1、现场测量、记录的采集方式为劳动力密集型数据采集方式，随着锂电池组的广泛应用，人力、物力投入巨大，费时费力。1. The collection method of on-site measurement and recording is a labor-intensive data collection method. With the wide application of lithium battery packs, the investment of manpower and material resources is huge, which is time-consuming and labor-intensive.

2、对锂电池组的故障起不到预警作用，只有故障发生了才知道锂电池组发生了故障，对故障分析缺乏可靠数据。对后续改进增加了难度，且大幅度增加了售后成本。2. It does not have an early warning effect on the failure of the lithium battery pack. Only when the fault occurs can the lithium battery pack be known to have a fault, and there is a lack of reliable data for fault analysis. It increases the difficulty of subsequent improvement and greatly increases the after-sales cost.

3、需记录内容较多，人为记录方式所记录数据出错率较高，可能会导致故障误判等现象。所记录数据没有系统管理，数据杂乱，数据分析较为困难。3. There is a lot of content to be recorded, and the error rate of data recorded by artificial recording methods is high, which may lead to misjudgment of faults and other phenomena. The recorded data is not systematically managed, the data is messy, and data analysis is difficult.

4、不便于对锂电池组做失效分析。4. It is not convenient to do failure analysis on the lithium battery pack.
