Abstract

The invention discloses a burning verification method of an electric quantity management and current monitoring IC of a battery core. The burning verification method includes a burning method and a verification method of battery information, the verification method includes a current verification method and an electric quantity verification method, and the electric quantity verification method comprises the steps of S1, firstly, verifying electric quantity values of multiple electric quantity management and current monitoring IC samples according to an electric quantity management and currentmonitoring IC verifying mechanism, and recording verifying coefficients of all channels; S2, secondly, conducting data processing on the verifying coefficients in the step S1; S3, thirdly, writing theprocessed verifying coefficients in the step S2 into upper computer software in a fixed value mode, and calling the verifying coefficients from the upper computer software while burning; S4, finally,during burning, monitoring the number of poorly verified electric quantity management and current monitoring IC products, returning to the step S1 if a reject ratio reaches a set value, otherwise continuing burning. The burning verifying method of the electric quantity management and current monitoring IC of the battery core is used for improving the burning and calibrating verification efficiency of the electric quantity management and current monitoring IC of the battery core.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery testing method equipment, in particular to a method for power management of a battery cell and a method for burning and verifying a current monitoring IC. Background technique [0002] In the lithium-ion battery industry, outsourced communication boxes are generally used to set up a single-channel mode to monitor, calibrate, and verify high-precision current. This method is limited by TI chips and technical support. The scalability and limitations are large, and the cost is too high. At the same time, in the industry, calibration and verification tests for products in the field of power management and current monitoring are inefficient, and the test takes a long time, which seriously affects the achievement of delivery. Contents of the invention [0003] The technical problem solved by the invention is to propose a method for efficient power management and burn-in verification of a...
