AI Technical Summary

Technical Problem

In existing technologies, battery SOP testing requires manual setup of the test environment, resulting in poor accuracy and making automated testing impossible.

Method used

The SOP testing system, including a host computer, BMS controller, and VT system cabinet, receives test environment parameters, obtains battery cell temperature sequence, SOC, and SOH, uses a pre-stored power table to determine the BMS lookup power, and automatically judges whether the current BMS actual power is qualified.

Benefits of technology

Automated testing has been achieved, improving the accuracy of SOP testing, avoiding oversights and subjective judgment biases in manual operation, and significantly shortening the testing cycle.

Abstract

This application belongs to the field of battery technology and discloses a testing method and apparatus for Standard Operating Procedure (SOP). The method includes: a Battery Management System (BMS) controller receiving test environment parameters from a VT system cabinet; a host computer sending a command to the BMS controller to close a high-voltage relay, and the BMS controller inputting a high-level signal to the relay; according to a timer of preset duration, the BMS controller acquiring the current battery cell temperature sequence, current State of Charge (SOC), and current State of Harshness (SOH) within the preset duration; based on the current battery cell temperature sequence, current SOC, current SOH, and a pre-stored power table corresponding to SOC and battery cell temperature, the BMS controller determining the current BMS lookup power; the BMS controller acquiring the current BMS actual power, and based on the current BMS lookup power and the current BMS actual power, determining whether the current BMS actual power is qualified; if qualified, the current BMS actual power is taken as the SOP. Using this application can improve the accuracy of SOP testing.
