Intelligent management system and management method for battery pack

Abstract

The invention discloses an intelligent management system and management method for a battery pack. The management system is arranged in the battery pack and a charger / electric apparatus circuit unit, and comprises a diverter, a recorder, an equalizer, a microprogrammed control unit (MCU), a storage unit, a data transmission unit and a battery chip, wherein the recorder is used for sampling battery parameters; the equalizer is used for carrying out electric quantity equalization on the battery pack; and the MCU is used for collecting the battery temperature, battery ID number instructions, voltage data of two poles of each battery and the voltage data of two ends of the diverter, judging whether the working states of the batteries are normal or not, and making the data into a data packet to transmit to a mobile phone. According to the intelligent management system and management method, the overall quality of the batteries can be improved, so that the service life of the batteries is prolonged. Usage information of the batteries is uploaded to a cloud platform; and battery manufacturers can optimize the battery design according to the read data of the cloud platform, and control the quality of the production link, so that the battery with relatively good performance is provided.

Description

technical field [0001] The invention relates to a battery pack intelligent management system and management method. Specifically, the information collection and transmission device is used to transmit the battery working information to the cloud platform, so as to provide battery working parameters for the design and production of the battery. At the same time, the early failure of the battery is intervened to improve the service life of the battery. Background technique [0002] Today, human beings have entered the era of contradictions between energy and the environment. On the one hand, a large amount of energy that produces a large amount of harmful emissions is used in large quantities, causing serious damage to the environment and threatening the living environment of human beings; Energy, such as oil. To reverse this situation, clean energy has become the driving force for future development. At present, electric energy is one of the most promising clean energy so...

Problems solved by technology

Since batteries are based on electrochemical reactions, it is difficult to control the quality of batteries due to the complexity and non-reproducibility of electrochemical reactions in the production process.

Due to the variability of manufacturing, it is impossible to ensure that the performance of each battery is exactly the same, so this phenomenon called "single lagging" exists

Power batteries are often used in groups in parallel, series or mixed connection, and in the process of use and maintenance, due to the performance difference (internal resistance, charge acceptance, etc.) The performance of one or several batteries in the battery pack declines rapidly. Even if a new single battery is replaced to form a new battery pack, due to the difference in performance from other batteries in the pack, different performances will appear in a short period of time. Affects the entire battery pack

The battery deteriorates abnormally due to various reasons during use, causing losses to users, repairers and manufacturers; with the current detection methods and means, the detection time of faulty batteries is long, and users and repairers cannot afford the damage caused by battery maintenance. During the downtime, we had to blindly replace the old one with the new one, causing artificial value loss

With the expansion of battery application scale, the above phenomena not only cause serious dissatisfaction of users, but also increase the cost of manufacturers, and the batteries themselves are eliminated at the end of their abnormal life, which also causes certain environmental loads and socio-economic impacts. loss of value etc.
