The System Architecture Design about Test Platform of Battery Management System

The battery management technology is one of the key technologies in new energy battery promotion and application, and it is related to the security and life of the battery. For the convenience of a battery management system scale production in the future, a kind of test platform architecture is proposed according to the developed battery management system. The architecture includes a battery management system test platform and the tested battery management system, the battery management system test platform consists of the battery simulation signal source and the man-machine interface of the host computer. The required various battery condition simulation signals produced by the battery simulation signal source are controlled by the calibration parameters of the host computer; The man-machine interface is completed based on LabVIEW development environment, which is used to control the output of the battery simulation signal source, meanwhile it can collect, analyze and process operating parameters from the tested battery management system and diagnose self, thereby the test results and evaluation are given. The test results show that the test platform can achieve the calibration control function of battery simulation signal source as well as the test function to the battery management system, which has good real-time performance and reliability, and has certain significance to the industrialization of the battery management system.
