Abstract

The invention discloses a data determination method and device. The method comprises the steps that stress data of a battery are acquired, and the stress data are data influencing the attenuation rateof the battery; a battery life attenuation model of the battery is established based on the stress data, wherein the battery life attenuation model is at least used for reflecting a relationship between the stress data and a battery attenuation rate; and life attenuation data of the battery is determined according to the battery life attenuation model. According to the invention, the technical problem that the battery life attenuation data cannot be effectively determined in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, to a method and device for determining data. Background technique [0002] Due to the different aging effects caused by the interaction of many factors in the environmental conditions of the battery or the use mode, the aging and degradation process of the battery is very complicated. Since the aging and degradation process of the battery does not depend on the same influencing conditions, it is difficult to identify the battery. Therefore, it is very important and challenging to establish a mechanism for identifying battery aging and degradation to determine the life decay state, which has caused many researchers to explore unremittingly for many years. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a method and device for determining data, so as to at least ...
