Battery testing in laboratory environments comes with its inherent limitations, such as bounded testing durations and a limited number of testing channels [ 36 ]. A common approach to bridge the gap between lab tests and real-world scenarios involves emulating real-world loading patterns within the laboratory.
Applying the laboratory simulation to a real-world scenario is one of the primary challenges in lithium-ion battery fault diagnosis, and there are few solutions available. Gan et al. realized the accurate diagnosis of OD fault by training the unified framework of voltage prediction based on the predicted voltage residual.
The research on battery system fault diagnosis for real-world vehicles is still in the initial stage. More vehicle data can be added to these researches with vehicle access to the platform and the accumulation of operation data. The study will become more and more perfect, and such ideas have excellent application prospects.
The current and temperature data also plays an important role in lithium-ion battery fault diagnosis. By mathematically processing the voltage and temperature data and calculating the cells' similarities, it is possible to realize the OC and OD diagnosis and TR early warning for EVs .
There are many fault data sources for lithium-ion batteries. Despite the differences in the data sources, they are not independent owing to the resemblances in battery material and group mode. One of the key problems is how to utilize the lithium-ion battery data from multi-sources, build the lithium-ion battery fault dataset.
The mathematical model cannot be determined in the battery system fault diagnosis, or the model cannot accurately describe the battery state. A large amount of monitor and sensor data can be conducted to diagnose the fault by using data-driven methods .
