Can a fault diagnosis scheme be used for multi-type sensors in battery packs?

This study set out to propose an effective fault diagnosis scheme for multi-type sensors in battery packs. The scheme aims to solve the problem that the traditional approach is only suitable for diagnosing the specific sensor or can not isolate battery fault, improving the security of the battery system. The specific work is summarized as follows.

Can a battery pack detect a temperature sensor fault?

proposes a fault diagnosis scheme of voltage and current sensors for the battery pack. The stochastic hybrid automaton models the battery pack as a hybrid system. The unscented particle filter (UPF) is used to diagnose sensor faults. Obviously, these studies ignore the temperature sensor fault.

How to identify a fault in a battery pack?

The residuals are compared with the constant threshold to identify faults of current and voltage sensors for the battery pack. The temperature sensor is assumed to be fault-free, which is used to distinguish whether the fault is in sensors or batteries. Ref. proposes a fault diagnosis scheme of voltage and current sensors for the battery pack.

Can multi-sensor fault diagnosis be performed in lithium-ion battery packs?

This work presents a feature-based method for multi-sensor fault diagnosis in lithium-ion battery packs. Fault detection and fault mode identification of sensors within the battery pack are accomplished without the need to establish battery models and set diagnosis thresholds.

Can a sensor FD scheme accurately isolate battery faults?

The battery fault only affects the estimation of voltage and core temperature of the battery. In summary, the sensor FD scheme proposed in this paper can accurately isolate current, voltage, temperature sensors and battery faults. In the future, we will focus on battery sensor fault prediction and adaptive threshold research.

Do faulty sensors affect battery SoC estimation?

Besides, the multi residual evaluation makes it possible to isolate current, voltage, temperature sensors, and battery faults. (3) Sensor and battery faults are simulated to verify the proposed FD scheme. The experimental results show that faulty voltage and current sensors have significant impacts on battery SOC estimation.
