Abstract:Battery management system needs to detect battery faults and isolate fault sources in time for safer battery use. This paper proposes a fault diagnosis method of the lithium-ion power battery current/voltage sensor based on a fusion diagnosis factor. The proposed fusion diagnosis factor can accurately and quickly detect sensor faults and isolate fault sources by selecting different residual generation and evaluation methods for different situations. Moreover, the proposed fault diagnosis method based on it can correct State of Charge (SOC) estimation results through extending estimated state variables, called fault tolerant control. Experimental results demonstrate the feasibility and effectiveness of this method. In addition, no false alarms or missing alarms occurs.
