We conduct a comprehensive study on a new task named power battery detection (PBD), which aims to localize the dense cathode and anode plates endpoints from X-ray images to evaluate the quality of power batteries.
Power Battery Detection (PBD) aims to judge whether the battery cell is OK or NG based on the number and overhang. Therefore, object counting and localization are necessary processing for PBD, which can provide accurate coordinate information for all anode and cathode endpoints. Statistics of the X-ray PBD dataset.

At present, the analysis and prediction methods for battery failure are mainly divided into three categories: data-driven, model-based, and threshold-based. The three methods have different characteristics and limitations due to their different mechanisms. This paper first introduces the types and principles of battery faults.
As electric vehicles advance in electrification and intelligence, the diagnostic approach for battery faults is transitioning from individual battery cell analysis to comprehensive assessment of the entire battery system. This shift involves integrating multidimensional data to effectively identify and predict faults.
Among the numerous battery parameters, the output voltage of the battery is commonly utilized for predicting the timing of failure and diagnosing the type of failure. Shang et al. utilized a methodology of predicting failure time by analyzing the voltage sequence within a moving window, thus enhancing the precision of fault diagnosis.
The detection method of battery parameters in battery management system is simple and the accuracy is limited [, , ], but the accuracy of parameters is the direct factor affecting the fault diagnosis results. Wang et al. proposed a model-based insulation fault diagnosis method based on signal injection topology.

Your definition of "on battery power" is somewhat different to mine. The key states that I want to distinguish are: when the Pico is standalone ("on battery power"), but the power is still being supplied via the USB connector, from a rechargable USB power pack; when the system is connected over USB to a host computer (ie. "not on battery power")
