Abstract

The invention discloses a method and a device for calculating the short-circuit current of a battery, wherein the method includes: obtaining the integral capacity and the current capacity of the battery; calculating the first capacity difference between the integral capacity and the current capacity, and calculating according to the first capacity difference The short-circuit current of the battery; obtain the first real capacity and the second real capacity; update the first real capacity and the second real capacity according to the temperature impedance meter and the short-circuit current of the battery; according to the updated first real capacity and the updated second The real capacity calculates the second capacity difference; and updates the short-circuit current of the battery according to the second capacity difference. Accordingly, it is possible to accurately calculate the battery short-circuit current.

Description

technical field [0001] The invention relates to the technical field of battery detection, in particular to a method for calculating the battery short-circuit current, a device for calculating the battery short-circuit current and an electronic product. Background technique [0002] In the related art, the battery internal short circuit calculation method is generally calculated when the battery is in a static environment and battery parameters (including current, internal resistance, temperature, etc.) are relatively stable. However, during the actual use of the battery, its current is often in a fluctuating state according to the change of the output power. It is difficult to accurately calculate the short-circuit current of the battery through the above-mentioned method. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the first object of the present invention...
