Battery life prediction method and system

Abstract

The invention discloses a battery life prediction method and system. The method comprises the steps of calculating a predicted battery life value after the first actual use time of a battery accordingto a first life prediction curve and first working condition information, wherein the first working condition information comprises at least one of the first actual charge-discharge rate, the first actual discharge total capacity, the first actual use temperature, the first actual state of charge and the first actual use time of the battery, determining a first life correction coefficient according to the actual battery life value after the first actual use time and the predicted battery life value, and generating a second life prediction curve according to the first life correction coefficient and the first life prediction curve, and determining a life prediction result of the battery after the first actual use time according to the second life prediction curve. According to the technical scheme provided by the embodiment of the invention, the accuracy of predicting the life of the battery in the actual use process is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of batteries, and in particular, to a battery life prediction method and system. Background technique [0002] During the use of the battery, the battery will gradually age and cause its life to decay, affecting the performance of the vehicle. [0003] Before the battery leaves the factory, the life of the battery can be predicted through the life prediction curve at present, but the problem existing in the prior art is that it is impossible to accurately predict the life of the battery in the actual use process. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a battery life prediction method and system, which improve the accuracy of battery life prediction during actual use. [0005] In a first aspect, an embodiment of the present invention provides a battery life prediction method, including: [0006] According to the first life...
