Embodiment Construction

[0049] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0050] In order to ensure that the new energy vehicle power battery can provide and store energy in the best state, it is necessary to effectively monitor the state of the vehicle power battery to determine whether the power battery is abnormal. At present, the power battery can be quantified in the controlled environment of the laboratory Rule analysis, for exampl...

Abstract

The embodiment of the invention discloses a battery detection method and device. Detection data and standard data of a target battery are acquired, present electrochemical data can be calculated according to the detection data and reflects present electrochemical characteristic of the target battery, standard electrochemical data is calculated from the standard data and represents standard electrochemical characteristic of the target battery, the present electrochemical data is compared with the standard electrochemical characteristic to obtain a first comparison result, and a detection resultof the target battery can be determined according to the first comparison result. The present electrochemical characteristic which can reflect the target battery can be obtained according to detection data, so that whether the target battery is abnormal can be determined in the electrochemical aspect, and due to the fact that the electrochemical characteristic serves as a fundamental characteristic of the battery, the battery state determined according to the electrochemical characteristic is more accurate and has a higher prediction role, and the performance of the target battery is detectedmore comprehensively.

Description

technical field [0001] The invention relates to the technical field of battery detection, in particular to a battery detection method and device. Background technique [0002] With the rapid development of the economy and the enhancement of people's awareness of environmental protection, the utilization rate of new energy vehicles is getting higher and higher. Monitoring to determine whether the power battery is abnormal. [0003] However, most of the current anomaly detection methods for power batteries focus on quantitative law analysis in a controlled environment in the laboratory. For example, the internal resistance value of the power battery can be obtained to determine whether there is an abnormality in the internal resistance value to determine whether the power battery is abnormal. This detection method is relatively simple and cannot satisfy the comprehensive detection of the performance of the power battery. Contents of the invention [0004] In order to solve...
