Embodiment 1

[0039] like figure 1 As shown, the battery management system based on battery operation control includes an operation monitoring module, a charging monitoring module, a switching management module and an abnormality analysis module; the operation monitoring module is connected in communication with the switching management module and the abnormality analysis module, and the charging monitoring module is connected with the switching management module. And anomaly analysis module communication connection.

[0040] The operation monitoring module is used to monitor and analyze the running state of the battery: obtain the battery voltage data DY, release temperature data FW and cold liquid data LY when the battery is running; the acquisition process of the battery voltage data DY includes: obtaining the voltage of the battery when the battery is running The voltage value and the operating voltage range, the voltage value is directly obtained by the multimeter. The multimeter is al...

Embodiment 2

[0045] like figure 2 As shown, the battery charge and discharge protection method based on battery operation control includes the following steps:

[0046] Step 1: Monitor and analyze the operating state of the battery when the battery is running, and obtain the operating coefficient. Determine whether the operating state of the battery meets the requirements according to the value of the operating coefficient. When the operating state of the battery does not meet the requirements, send a message to the abnormality analysis module. Abnormal signal, when the battery state is switched, the charging current of the battery is monitored with the charging current assignment range;

[0047] Step 2: Monitor and analyze the charging state of the battery when the battery is charging and obtain the charging coefficient. Determine whether the charging state of the battery meets the requirements according to the value of the charging coefficient. When the operating state of the battery do...

Abstract

The invention belongs to the field of battery management, relates to a data analysis technology, is used for solving the problem that the accuracy of a monitoring analysis result is not high due to the fact that a traditional battery management system cannot set an accurate monitoring standard for the charging and discharging process of a battery, and particularly relates to a battery charging and discharging protection method and management system based on battery operation control. Comprising an operation monitoring module, a charging monitoring module, a switching management module and an abnormity analysis module. The operation monitoring module is in communication connection with the switching management module and the abnormity analysis module, and the charging monitoring module is in communication connection with the switching management module and the abnormity analysis module; according to the invention, through the switching management module, the charging current assignment range and the transport current assignment range of the battery can be automatically analyzed, so that the state of the battery can be monitored and analyzed according to a current amplitude standard after state switching, the battery can be charged and discharged in a safe and stable environment, and the service life of the battery is prolonged.

Description

technical field [0001] The invention belongs to the field of battery management and relates to data analysis technology, in particular to a battery charge and discharge protection method and a management system based on battery operation control. Background technique [0002] Secondary batteries have the following shortcomings, such as less energy storage, short life, problems in series and parallel use, safety in use, difficulty in estimating battery power, etc. The performance of batteries is very complicated, and the characteristics of different types of batteries are also very different. The main purpose of the battery management system is to improve the utilization rate of the battery, prevent the battery from overcharging and overdischarging, prolong the service life of the battery, and monitor the status of the battery. With the development of the battery management system, other functions will also be added. [0003] The existing battery management system can monitor...
