However, the proposed methods in these works [, , , ] are mainly based on the voltage data of a single cell in battery packs, and they cannot accurately diagnose faults and anomalies incurred by variation of other parameters, such as current, temperature and even power demand.
As discussed above, the faults diagnosis and abnormality of battery pack can be detected in real time. In addition, timely detection and positioning of faults and defects of cells can improve the health and safety of the whole battery pack.
By applying the designed coefficient, the systematic faults of battery pack and possible abnormal state can be timely diagnosed. 2) The t-SNE technique, The K-means clustering and Z-score methods are exploited to detect and accurately locate the abnormal cell voltage.
It is the battery that causes the problem. A challenge when reading the instruction manual is that it says you can get three Cell Error messages: CELL ERROR LOW VOLTAGE – Voltage of one cell in the battery pack is too low. CELL ERROR HIGH VOLTAGE – Voltage of one cell in the battery pack is too high.
Common electrical faults of battery packs can be divided into three categories: abuse , sensor faults and connection faults . Battery abuse faults mainly refer to external short circuit (ESC), internal short circuit (ISC), overcharge and over-discharge.
Sometimes multiple cells have their protection combined on a single associated board but per-cell circuit is provided as it is not safe or advisable (maybe that's "neither advisable nor safe") to use multi-cell protectors alone. The overall battery of cells may have an added layer of protection above the individual protectors.
