Abstract

The invention discloses a method and a device for detecting the health state of a battery. Wherein, the detection method includes: obtaining at least two health values ​​among the first health value, the second health value and the third health value of the battery; obtaining the weight of each health value of the at least two health values; value and the individual weights determine the battery's state of health value. The invention solves the technical problem that the battery health state cannot be accurately evaluated, and realizes accurate evaluation of the battery health state.

Description

technical field [0001] The invention relates to the field of automobile batteries, in particular to a method and device for detecting the state of health of a battery. Background technique [0002] In the working process of new energy vehicles, communication equipment and some other equipment, it is often necessary to keep the battery in good health for a long time, because the health of the battery has an important impact on the function of the equipment. For example, the power battery of an electric vehicle, when the service life of the power battery exceeds the battery life or the number of charge and discharge cycles reaches the upper limit, the energy that the power battery can store will gradually decay, resulting in a serious shortening of the cruising range of the electric vehicle. Therefore, during the use of the battery, it is often necessary to estimate its health status, and when the battery life reaches the end, an early warning message is issued to prompt the u...
