Abstract

The invention relates to the technical field of a battery management system, aims to solve a problem of incomplete fault processing in a battery management system in the prior art and provides a battery management system fault FDIR system and method based on double redundancy. The system includes a first data acquisition module, a second data acquisition module, a resolution redundancy module, a hardware redundancy module and a fault reconstruction module, wherein the first data acquisition module is connected with the analysis redundancy module, the second data acquisition module is connectedwith the hardware redundancy module, and the fault reconstruction module is respectively connected with the hardware redundancy module and the analysis redundancy module. The battery management system is detected, isolated and reconstructed through hardware redundancy and analytical redundancy, not only can faults of a battery pack be detected accordingly, but also hardware faults of the batterymanagement system can be processed, comprehensive fault processing of the battery management system is achieved, and the method is suitable for the battery management system.

Description

technical field [0001] The present invention relates to the technical field of battery management systems, in particular to a fault FDIR system and method. Background technique [0002] In the development process of today's new energy technology, batteries as energy storage devices have been widely used in various new energy products, such as new energy vehicles, new energy ships, etc. Limited by the raw materials and manufacturing process of the battery, single batteries need to be used in series and parallel on a large scale to form a battery pack to meet the capacity, voltage and current requirements of new energy products. This also brings a series of problems such as large number of series and parallel nodes, complex system, high safety and durability requirements, etc. It is necessary to use the battery management system to monitor and manage the battery pack, and to monitor the potential problems of the energy storage system in the new energy technology. Fault predic...
