Based on the application of the power batteries, this paper uses a statistical method to estimate the internal resistance and open-circuit voltage of Ni-MH battery. Battery status is monitored and simulated by battery pack test bench. Through using ideal battery model and fitting the data of measured voltage and current, the battery internal resistance and open-circuit voltage are estimated. Th...

In terms of the battery management system a mobile music speaker, reliability optimization has always been an important topic. This paper proposes new dynamic redundant algorithm based on existing fault-tolerant structure lithium pack. The internal configuration is adjusted according to SOC each battery, and power supply dynamically allocated. selects four batteries experiment with two differen...

To accurately estimate the state of charge of a lithium-ion battery pack used in electric vehicles, a neurofuzzy system is proposed. The subtractive clustering is used to determine the structure and the initial parameters of the neuro-fuzzy system to reduce heuristic errors. The algorithm of adaptive neuro-fuzzy inference (ANFIS) is adopted to optimize the parameters of the neuro-fuzzy system. ...

This paper presents a model-based cell-health-conscious thermal energy management method. An Arrhenius equation-based mathematical model is firstly identified to quantify the effect of temperature on the cell lifetime of a Nickel Metal Hydride (NiMH) battery pack. The cell aging datasets collected under multiple ambient temperatures are applied to extract the Arrhenius equation parameters. The ...

A new hybrid system of a tracked bulldozer is designed, which primarily consists of an engine-generator set, a battery pack, and a supercapacitor. According to the power requirements of typical working conditions and the output feature of three power sources, a fuzzy control and wavelet transform-based energy management strategy is proposed. Models of the hybrid system are built in Matlab/Simul...

This paper proposes a method to estimate state of charge (SoC) for Lithium-ion battery pack (LIB) with
