Electrochemical models and equivalent circuit models have been the most common choices for simulation of the performance of lithium-ion battery. However, most models do not consider the temperature effect on the battery parameters, which leads to large simulation error when battery is under subzero operation conditions. Actually, low ambient temperature operation condition is inevitable for EVs and...
Tube receiver with pin fin arrays inserting was introduced as the absorber tube of parabolic trough receiver to increase the overall heat transfer performance of tube receiver for parabolic trough solar collector system. The Monte Carlo ray tracing method (MCRT) coupled with Finite Volume Method (FVM) was adopted to investigate the heat transfer performance and flow characteristics of tube receiver...
Accurate prediction of battery's remaining useful life (RUL) is significant for the reliability and the cost of systems. This paper presents a new Particle Filter (PF) framework for lead-acid battery's RUL prediction by incorporating the battery's electrochemical model. An electrochemical model that simulates the charging and discharging of lead-acid battery is introduced. The effectiveness of both...
Accurate battery state of charge (SOC) estimation conduces to establishing an ideal charging and discharging strategy for battery management system (BMS). And it can also prevent serious damage to battery (pack) from over-charging or over-discharging. This paper firstly establishes a simplified mechanistic model for LiFePO4 battery. Parameter identification conditions are originally designed based...
Constant current-constant voltage (CC-CV) charging and pulse current charging are the usual methods for charging Li-ion batteries. Because we are lack of the direct in-situ measurement of Li-ion battery's internal state, both of the two charging methods are controlled without feedbacks from inside of the battery. A new charging method is proposed in this paper based on electrochemical-thermal coupling...
