Previously, we found Lactobacillus plantarum had probiotic effects on lined seahorse (Hippocampus erectus) juveniles by the addition Lactobacillus directly into rearing seawater containing juveniles and their food (i.e. copepods). However, how the juveniles consumed Lactobacillus, directly from water or from copepods in whose guts Lactobacillus may have accumulated by ingestion, is still unclear....
The state-of-health (SOH) of a lithium-ion battery is a key parameter in battery management systems. However, current approaches to estimating the SOH of a lithium-ion battery are mainly offline or have not solved the accuracy and efficiency problems. This paper attempts to solve these problems. A dynamic information extraction method based on a fast discrete wavelet transform is proposed to greatly...
Physics-based model has been regarded as a promising alternative to equivalent circuit model due to its ability to describe internal electrochemical states of battery. However, the rigorous physics-based model, namely pseudo-two-dimensional (P2D) model, is too complicated for online application in embedded battery management system. In this paper, to simplify the P2D model, a series of polynomial...
Physics-based models for lithium-ion battery have been regarded as a promising alternative to equivalent circuit models due to their ability to describe internal electrochemical states of battery. However, the huge computational burden and numerous parameters of these models impede their application in embedded battery management system. To deal with the above problem, a reduced-order physics-based...
Li-ion batteries have been widely used as the power source of electric vehicles. However, the acquisition of precise state of charge via battery management system remains a problem. A root cause is the complex characteristics of battery polarization, which is affected by the load current. In order to improve the accuracy and reliability of battery state of charge estimation, this paper focuses on...
The practical application of electric vehicle needs an accurate and robust battery management system to monitor the battery state in real-time. The maximum available capacity (MAC) and maximum available energy (MAE) need to be derived before calculating state of charge and state of energy. However, the estimation of these two parameters is a difficult task due to the complicated and comprehensive...
The key technology of a battery management system is to online estimate the battery states accurately and robustly. For lithium iron phosphate battery, the relationship between state of charge and open circuit voltage has a plateau region which limits the estimation accuracy of voltage-based algorithms. The open circuit voltage hysteresis requires advanced online identification algorithms to cope...
