Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] Such as figure 1 Shown, a kind of lithium-ion battery residual life prediction method, comprises the following steps:

[0034] Step 1, collect the status data of the lithium-ion battery, including the cut-off voltage, current, capacity, etc. of the lithium-ion battery.

[0035] Step 2, according to the status data, use the ampere-hour integration method to obtain the power data of the lithium-ion battery.

[0036] Step 3, input the power data into the pre-trained quantum echo state network to obtain the remaining life of the lithium-ion battery.

[0037] Quantum echo state network is a hybrid network combining quantum computing method and echo state network (ESN). The construction proc...

Abstract

The invention discloses a lithium ion battery residual life prediction method and system. The method comprises the steps of collecting state data of the lithium ion battery; acquiring electric quantity data of the lithium ion battery according to the state data; and inputting the electric quantity data into a pre-trained quantum echo state network to obtain the residual life of the lithium ion battery. The invention further discloses a corresponding system. Through the quantum echo state network, the residual life of the lithium ion battery is effectively predicted, and the method has important significance for guaranteeing safe and reliable operation of equipment.

Description

technical field [0001] The invention relates to a method and system for predicting the remaining life of a lithium ion battery, belonging to the field of battery health management. Background technique [0002] With the rapid development of modern science and technology, electronic products play a vital role in people's daily entertainment life. The remaining life of the battery is related to whether an electronic product can be used normally, and directly affects the normal, effective and efficient operation of various electronic products. Safe to use. Therefore, there is an urgent need for a remaining life prediction method, which is of great significance to ensure the safe and reliable operation of equipment. Contents of the invention [0003] The invention provides a method and system for predicting the remaining life of a lithium-ion battery, which solves the problems disclosed in the background technology. [0004] In order to solve the problems of the technologies...
