Accurate prediction of the remaining useful life for lithium-ion battery is beneficial to prolong the life of the battery and increase safety. With the capacity degradation curve obtained from the data of the battery charge and discharge experiment, the remaining useful life of the battery was predicted by using particle filter.
In recent years, research on the state of health (SOH) and remaining useful life (RUL) estimation methods for lithium-ion batteries has garnered significant attention in the new energy sector. Despite the substantial volume of annual publications, a systematic approach to quantifying and analyzing these contributions is lacking.
NREL’s battery lifespan researchers are developing tools to diagnose battery health, predict battery degradation, and optimize battery use and energy storage system design.
The calculation of battery remaining useful life can be expressed by the following formula: Where RUL represents the remaining useful life. is the number of cycles when the battery failure threshold is reached. is the number of cycles which is at the end point of filter tracking and also the starting point of the prediction.
This provides a new solution for predicting the state of health (SOH) and remaining useful life (RUL) of lithium-ion batteries. Kim et al. (2022) introduced a hybrid model, KIRNN, combining empirical models with deep neural networks to enhance the accuracy and robustness of estimating battery health and remaining lifespan.
Life Prediction Model for Grid-Connected Li-Ion Battery Energy Storage System, American Control Conference (2017) NREL researches the chemical and mechanical degradation, performance, excess energy, thermal management, second use, and other business decision factors in battery reliability.
