The electromagnetic environment of the lithium-ion battery in the Electric Vehicles (EVs) is severe. Moreover, the load current of the battery in the EVs changes drastically and randomly depending on the EV driving condition. As a result, the voltage and current signals measured by the Battery Management System (BMS) normally contain the noise such as the white noise. This results in the estimation...
With the sinusoidal charging scheme, the large dc link capacitance of the on-board battery charger can be reduced significantly. However, the variable charging current together with the wide battery voltage range imposes serious challenge to maintain high efficiency throughout the whole charging procedure. This paper proposes a LLC dc-dc transformer (DCX) battery charger solution to improve the efficiency...
This paper proposes a hierarchical battery balancing architecture for the series connected lithium-ion batteries. The battery cells are grouped into different packs and the bottom layer is the Adjacent Cell-to-Cell structure consisting of the packs. The top layer is connected to different packs and can deliver the energy from one pack to any other pack bi-directionally, leading to high flexibility...
This paper proposes a new distributed battery energy architecture based on the micro-bank modules for DC microgrids. The benefits of the proposed architecture include 1) no voltage sharing problem and no overcharge/overdischarge problem; 2) high compatibility and reliability 3) high energy utilization efficiency; 4) reduced volume and weight of the BMS. Taking advantage of the battery recovery effect,...
