A method for power management of battery cells and burning verification of current monitoring ic

Abstract

The invention discloses a method for battery power management and current monitoring IC burning verification, which includes a battery information burning method and a verification method, and the verification method includes a current verification method and a power verification method. The steps of the power calibration method are as follows: first, calibrate the power values ​​of multiple power management and current monitoring IC samples according to the calibration mechanism of power management and current monitoring ICs, and record the calibration coefficients of each channel; then, in step S1 The calibration coefficients are used for data processing; again, write the processed calibration coefficients in step S2 into the host computer software in the form of fixed values, and call them from the host computer software when burning; finally, during the burning process, monitor the calibration The number of bad power management and current monitoring IC products, if the bad rate reaches the set value, return to step S1, and if the bad rate does not reach the set value, continue programming. The invention is used to improve the power management of electric cores and the efficiency of programming calibration and verification of current monitoring ICs.

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...
