An automatic equivalent-circuit parameter-estimation system for a Lithium-ion battery including battery temperature controller is developed in this paper. The system consists of a thermostatic chamber and estimating programs for parameters of an internal voltage and of an internal impedance, which is expressed by two resistors and a capacitor. These resistances increases by more than 60% and above,...
The battery online monitoring device is regarded as the research object, a scheme based on Cirrus logic's EP9315 processor and embedded Linux operating system is proposed. Short-distance wireless communication technology is adopted to transfer data. The hardware structure and software design of the system are also introduced. The battery inner resistance is measured by DC discharge, which guaranteed...
In this paper a solar battery charging procedure for NiHM batteries is presented. The article shows how it is possible to detect a true full state of charge avoiding false charge termination due to changing illumination conditions.
Electric vehicles (EVs) are fundamental components for a sustainable mobility. Unless a major technological breakthrough is achieved in energy storage and battery technology, EVs future will pass by multiple energy sources hybridisation, to benefit from the best characteristics of the energy sources available. In this paper, the energy and the mobility problems are introduced as well as the relevance...
