Design of a Test Bench for Battery Management

Sammanfattning: The report deals with energy conservation, mainly in the field of portable energy, which is asubject that today raises questions around the world. This report describes the design and theimplementation of a Battery Management System on the platform NI ELVIS II+ managed bythe software Labview. The first aim has been on finding information about the design of theBattery Management System that corresponds to the choice of the battery itself. The systemwas designed completely independent with different charging methods, simulations ofdischarge, and its own cell balancing, as a 3 cells battery pack was used. The battery chosenwas the lithium-ion technology that has the most promising battery chemistry and is the fastestgrowing. Several experimentations and simulations have been done, with and without cellbalancing that permited to highlight that the cell balancing is mandatory in a Batterymanagement System. Furthermore, a simulation of use of the battery in an Electrical Vehiclewas made, which can lead to conclude that the Lithium-Ion battery must be manageddifferently to be used in the application of an Electrical Vehicle.
