Abstract :
Just-in-time detection of anomalies in automotive batteries can proibit a viral propagation of the problem within the energy storage system. Given the cost associated with replacement of energy storage system in electric and hybrid electric vehicles, an effective condition monitoring can translate to substantial savings and reduced downtime. In this paper a condition monitoring technique based on the impulse response of the electrochemical batteries has been proposed. This method is capable of detection of abnormal operating characteristics in battery cells within an energry storage system while the unit is performing its intended function. Simulation and experimental results are provided to illustrate the practicality of the proposed method.
