Prediction of the Remaining Useful Life of Supercapacitors at Different Temperatures Based on Improved Long Short-Term Memory

Abstract: As a novel type of energy storage element, supercapacitors have been extensively used in power systems, transportation and industry due to their high power density, long cycle life and good low-temperature performance. The health status of supercapacitors is of vital importance to the safe operation of the entire energy storage system. In order to improve the prediction accuracy of the remaining useful life (RUL) of supercapacitors, this paper proposes a method based on the Harris hawks optimization (HHO) algo… Show more

“…On the other hand, because there is no backgate, electrostatic doping is not feasible for graphene-based Hall sensors on foil substrates. Under these conditions, it becomes more practical to use an encapsulating layer to reduce the amount of carriers or increase sensitivity. In practical applications, the enclosing layer serves as a barrier to protect the graphene material from external stimuli, ensuring a consistent Hall sensor performance. …”

“…The predictions demonstrate that the suggested method is more accurate and robust than conventional gated recurrent unit (GRU) and LSTM models. [ 29 ] Athanasios et al (2023) proposed a novel data preprocessing strategy applied to ANN training data. Then, they evaluated the efficiency of the proposed model produced to show the advantages obtained.…”

“…Moreover, in the mode of nondirect power supply, the nanogenerator can also input the converted electrical energy into the battery of the acoustic device (headphones, speakers, etc. ), providing convenience for predicting the health of the battery. Therefore, the combination of nanogenerator and acoustic equipment also has great application potential and high research significance in other fields.…”
