Predicting a potential fault in a battery
In a status detection system, a data acquisition circuit monitors statuses of a battery to generate status data. A storage medium stores a set of lookup tables. A lookup table of the lookup tables includes a set of datasets corresponding to a set of time frames. Each dataset includes digital values of parameters of the battery obtained in a corresponding time frame of the time frames. A controller receives the status data and updates the lookup tables based on the status data. The controller also obtains a current dataset of the parameters based on the status data, searches the lookup table for a previous dataset that matches the current dataset, compares a current value of a parameter in the current dataset with a previous value of the parameter in the previous dataset, and determines whether a potential fault is present in the battery based on a result of the comparison.
