Abstract

The invention provides a functional verification platform of a battery management system, which can comprehensively detect whether the battery management system works normally and the functions are complete in an off-line state. The platform is composed of a special signal generating module, a measuring and controlling system, a man-machine interaction platform and a controller area network (CAN) transceiver module. The platform can realize the normal working of the battery management system in the off-line state by generating total voltage analog signals, module voltage analog signals, total current analog signals, temperature analog signals and handshaking signals, and can process the preset functions as well. In addition, the battery management system feeds back work task results to the functional verification platform in the form of CAN communication. The results output by the battery management system at present are compared with instructions input by the functional verification platform, the hardware, driver software and application software functions of the battery management system can be verified fast.

Description

Technical field [0001] The invention belongs to a function verification platform, and in particular relates to a battery management system function verification platform. Background technique [0002] As the world's awareness of energy conservation and environmental protection increases, the development trend of hybrid vehicles is growing. The power battery pack is a key component of a hybrid vehicle, and it needs to be monitored in real time by a battery management system. Whether the function of the battery management system meets the actual requirements must be verified, so as to discover the defects of the battery management system in time and avoid accidents during the operation of the entire vehicle. Therefore, in the research of hybrid electric vehicles, it is of great significance to design an economical and effective battery management system functional verification platform. [0003] In the existing patents, there are related descriptions of the battery management syste...
