Different fault detection approaches based on model, signal-processing, or knowledge can be applied for the battery. The model-based approaches consider an electrochemical model or an equivalent circuit model, to detect faults.
Some simulations have been conducted on a Lithium-ion battery cell and extended to battery pack, to demonstrate the performance of the proposed approach in more real-world scenarios. The results showed that the designed observers can detect faults correctly in a seven years old battery as well as a new one. 1. Introduction
In this paper, a novel model-based fault detection in the battery management system of an electric vehicle is proposed. Two adaptive observers are designed to detect state-of-charge faults and voltage sensor faults, considering the impact of battery aging.
Then, it is assumed that aging effects are time-varying. Therefore, the fault detection scheme can detect faults of new battery cells as well as aged cells. Some simulations have been conducted on a Lithium-ion battery cell and extended to battery pack, to demonstrate the performance of the proposed approach in more real-world scenarios.
Fault detectors are designed considering battery aging effects: capacity fading and resistance growth. Aging effects are considered in two cases: time-invariant and time varying parameters. In this paper, a novel model-based fault detection in the battery management system of an electric vehicle is proposed.
