Problems solved by technology

[0003] Traditional monitoring of lead-acid batteries can only use measuring instruments to test their voltage, current, internal resistance, temperature and capacity, and cannot predict the remaining operating cycle life of the battery in this environment through real-time monitoring parameters
The running lead-acid battery can only be replaced when an accident occurs, or it is replaced blindly, which is a passive replacement of the battery, which brings safety hazards to life and production

Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:

[0043] Examples such as Figure 1-Figure 3 As shown, in this embodiment, it is assumed that 1 lead-acid battery operation performance removes the influence of physical damage factors; it is assumed that 2 lead-acid batteries can be charged in time after running and discharging, so as not to be affected by vulcanization; 400AH second-class valve-regulated lead Acid battery cells were used as research samples.

[0044] Step 1: Analyze the factors that affect the performance degradation of lead-acid batteries, the relationship between performance degradation and changes in various operating parameters, and determine the parameters that affect the performance degradat...

Abstract

A lead acid battery application life prediction system disclosed by the present invention comprises a parameter obtaining unit, an arithmetic unit and an output unit. The parameter obtaining unit obtains the discharge quantity value, the environment temperature and the residual capacity of a to-be-predicted lead acid battery under different environments and during a work engineering; the arithmetic unit comprises a failure average speed model calculation module for calculating an actual application failure coefficient of the to-be-predicted lead acid battery via an attenuation ratio and further establishing a failure average speed model of the battery with the failure coefficient, and a prediction decision function calculation module for setting a self-learning battery state of charge to be equal to an original bulk, and setting to obtain a least square support vector machine (LS-SVM) decision function when the battery failure coefficient is a constant and according to the structural risk minimization principle and a least square support vector machine; and the output unit outputs a life prediction result.
