AI Customer ServiceInconsistency evaluation methods are summarized as statistics-based, machine learning-based and information fusion-based methods. Moreover, the improvement measures of battery inconsistency are reviewed from the aspects of the production process, sorting technology, topology optimization, equalization control and thermal management.
It is of great significance to establish an effective evaluation method for the safe, efficient and reliable operation of the system. Battery pack is a complex electrical thermal coupling system, and there are many factors affecting its performance .
The consistency evaluation results are visualized through graphs and tables. Moreover, the evaluation results are used to analyze the mechanism of consistency evolution and explore the influencing factors. Fig. 7. The workflow of machine learning battery inconsistency evaluation.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
Further, Jeng et al. established a battery voltage (V) consistency evaluation method based on the autoencoder network. It integrates the advantages of the LSTM and convolutional neural network (CNN), so it has higher estimation accuracy than the traditional LSTM.
Inconsistent evaluation: These methods aim to evaluate the inconsistency of parameters by using machine learning algorithms to reflect the performance of battery pack. Fan et al. proposed a parameter consistency model based on the generative adversarial network (GAN) for the battery pack.
