Abstract

The present invention provides a battery state of health assessment method, a battery state of health assessment device, a storage medium and an electronic device. The method includes the following steps that: the battery parameters of a target battery are determined, wherein the battery parameters include the capacity increment of the target battery, the discharge capacity of the target battery and the battery internal resistance of the target battery; the battery parameters are analyzed with a first model, so that the state of health of the target battery can be determined, wherein the firstmodel is obtained by means of training through machine learning on the basis of a plurality of sets of data, wherein each set of data in the plurality of sets of data include the battery parameters and the states of health of batteries; and identification information for identifying the state of health of the target battery is outputted. With the battery state of health assessment method, the battery state of health assessment device, the storage medium and the electronic device of the invention adopted, the problem of failure to evaluate the state of health of a battery in real time and comprehensively in the prior art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a battery health status evaluation method, device, storage medium and electronic device. Background technique [0002] With the continuous promotion of electric vehicles, lithium batteries have also been widely used in the field of electric vehicles due to their green performance. Power battery is one of the key components of electric vehicles, and power battery technology greatly affects the performance and cost of electric vehicles. However, the performance of the on-board power battery gradually degrades with the charge-discharge cycle. It is generally believed that when the battery capacity is less than 80%, the battery needs to be replaced or maintained to avoid affecting the driving performance of the car and eliminate potential safety hazards. Therefore, it is necessary to evaluate the state of health (State of Health, which will become SOH) of the power battery for ele...
