Abstract

The invention discloses a configurable battery simulation system and method for detecting a BMS function, and the system comprises a dSPACE controller, a battery cell voltage simulation module, a temperature simulation module and an insulation resistance simulation module. The dSPACE controller is connected with the battery cell voltage simulation module, the temperature simulation module and theinsulation resistance simulation module through a MicroAutoBox hardware interface board. The battery simulation system is connected with a to-be-tested BMS, and is used for detecting the data acquisition accuracy and precision of the BMS system, the accuracy of the SOC estimation, the correctness of the fault diagnosis, whether the charging conforms to the protocol standard or not, and whether a vehicle can communicate normally or not, thereby achieving the comprehensive evaluation of the performance of the to-be-tested BMS system. The battery simulation system is configurable, and can establish a mathematical model of a battery according to the type, the total voltage and capacity of a to-be-simulated battery, or directly uses the experiment data to obtain the SOC-VOC characteristics of the batteries with different electrochemical characteristics, thereby configuring the characteristics of the simulated battery.

Description

technical field [0001] The invention relates to the field of battery management systems, in particular to a battery simulation system and method which can be configured to detect BMS functions. It is suitable for the detection of BMS systems in the fields of electric vehicles, hybrid vehicles, hybrid energy sources, hybrid energy storage systems, etc., and makes a comprehensive evaluation of the performance system of the BMS to be tested. Background technique [0002] Nowadays, environmental pollution and energy shortage are huge problems faced by all countries in the world. Electric vehicles are becoming more and more popular due to their green and environmental protection characteristics. Power batteries have become the main energy storage medium for electric vehicles due to their high energy density. . In traditional BMS (Battery Management System) development, it is usually necessary to pre-fabricate a complete battery pack to evaluate and verify the BMS. The patent li...
