Accurate state of charge (SOC) is critical for battery energy management system in electric vehicle (EV) application. Overcharge and over discharge will shorten battery's lifespan and induce potential safety problem, which may even permanently damage the lithium-ion battery. Thus, a data driven model is proposed for improving the accuracy of SOC estimation in this paper. A preliminary mathematic model...
This paper develops pipeline architecture of particle swarm optimization with random time-varying inertia weight and acceleration coefficients (PSO-RTVIWAC) based on existing serial architecture. The proposed architecture incorporated two features to reduce calculation error and keep high speed calculation with acceptable chip area cost. First, actual hardware design is simplified. Then the pipeline...
