Abstract

The invention relates to a lithium battery life cycle monitoring management method and system and a storage medium, and belongs to the field of lithium battery health management, and the method comprises the steps: obtaining lithium battery state information carrying a device ID according to a preset collection cycle, the lithium battery state information comprising a battery health state SOH; reading pre-stored equipment information corresponding to the equipment ID; based on the type of the lithium battery, selecting a pre-stored corresponding attenuation fitting function and rule configuration parameters; on the basis of the selected attenuation fitting function and rule configuration parameters, calculating to obtain an SOH boundary value; comparing the SOH of the battery with the SOH boundary value to obtain a lithium battery health level corresponding to the equipment ID, and updating the lithium battery health level to a preset health level database; and after a query request signal carrying the equipment ID is received, feeding back the lithium battery health level corresponding to the equipment ID. The method has the effect of facilitating the user to accurately evaluate the health state of the lithium battery.

Description

technical field [0001] The invention relates to the field of lithium battery health management, in particular to a lithium battery life cycle monitoring and management method, system and storage medium. Background technique [0002] Because of its high output voltage, long cycle life, high energy density, low self-discharge rate, and wide operating temperature range, lithium batteries are widely used in consumer electronics, electric vehicles, aviation, aerospace, navigation, military communications and other fields. [0003] With the increasingly widespread application of lithium-ion batteries, a series of problems have begun to be exposed during use, especially their health status. At present, the monitoring of lithium batteries usually adopts the following method: the lithium battery life cycle server regularly collects the state parameters of lithium batteries, and performs alarm and protection actions when the state parameters exceed reasonable values. [0004] In the ...
