Abstract

The invention discloses a charging and discharging control system and method of a battery module, belonging to the technical field. A charging and discharging control system of a battery module according to the invention comprises a data acquisition module for collecting various data; a data classification module for data classification; and a data processing for processing data, constructing functions and learning adjustments module; an instruction module for sending instructions; an output module for outputting results; a controller for simulating and controlling the instruction module; a charging and discharging control method for a battery module, comprising the following steps: S1, establishing a temperature database, Recording data; S2, recording the temperature conditions during different control instructions; S3, establishing a deep learning function model; S4, calculating the temperature difference; S5, performing self-correction and adjustment. The invention can improve the accuracy, reduce the amount of historical data, control the charge and discharge of the battery module, improve the life of the battery module, and reduce the risk of high temperature.

Description

technical field [0001] The invention relates to the technical field of battery charge and discharge control, in particular to a system and method for charge and discharge control of a battery module. Background technique [0002] In recent years, with the development and progress of science and technology, various electronic products have gradually been accepted and started to be used by people. As the energy supply of most electronic equipment, battery modules are aging rapidly and have high charging and discharging temperatures. is an important factor limiting its application. [0003] Due to the frequent application of battery modules in daily life, the increase in the number of charging and discharging cycles will lead to the aging of the battery module, and the charging and discharging of the battery module that is close to the end of life can easily cause an explosion and cause danger. At the same time, during the charging and discharging process, the ambient temperat...

Problems solved by technology

[0003] Due to the frequent application of battery modules in daily life, the increase in the number of charging and discharging cycles will lead to the aging of the battery module, and the charging and discharging of the battery module when it is close to being scrapped can easily cause an explosion and cause danger

At the same time, during the charging and discharging process, the ambient temperature in different seasons is different. For example, in summer, the temperature is high, and the temperature of the battery module rises faster. The charging and discharging operation at high temperature will cause a huge impact on the life of the battery module. In extreme cases, it may even cause fire and combustion, so it is very necessary to control the charge and discharge of the battery module

[0004] In the current technical means, most of the charge and discharge control only considers the inside of the battery and does not consider the external environmental factors, which causes a large error and easily affects the life of the battery module, and many technical means need to store a large amount of historical data for judgment , the system does not have self-learning and correction
