Abstract

The invention provides a battery pack simulation working method and system. According to the method, the system acquires the calibration parameter values ​​of the single cells in the battery pack, and determines the estimated coefficient of each of the single cells in the battery pack according to the preset difference characteristic distribution function of the single cells ; determine the parameter estimated value of the corresponding single battery based on the calibration parameter value and the corresponding estimated coefficient; by simulating the change of each single battery based on the parameter estimated value, to simulate the battery pack in the Changes in output parameters reflected during work. The invention can be closer to the working condition of the actual battery pack, and does not need manual setting, which is beneficial for technicians to set the actual battery pack balancing control strategy according to the simulated working conditions of the battery pack.

Description

technical field [0001] The invention relates to the field of battery pack testing, in particular to a battery pack simulation working method and system. Background technique [0002] BMS (Battery Management System) is a management system used to prevent individual batteries from being damaged due to the aggravation of differences in individual batteries. For BMS, being able to understand the status of each single battery (such as the current, voltage, temperature, etc.) of the single battery will be of great help to formulate coordination and control strategies. In order to formulate these strategies, a battery simulator is needed to simulate the differences in the characteristics of the single battery during operation (such as internal resistance, open circuit voltage, and capacity differences) and the differences caused by external factors (current differences, temperature differences, etc.). In fact, many battery packs contain dozens or even hundreds of single cells, so ...
