Design a circuit and simulate it to view output.
Circuit should be able to a balancing circuit to control the charging and discharging for lithium batteries pack in series on MATLAB or any similar software.
Balancing is made using a buck-boost converter.
All the schematic drawings , graphs , calculating and hand written notes from the expert should be provided. You need to simulate the design and need to construct the hardware design.
Project:
Active charge balancing for batteries or ultra-capacitors (E)
The latest Lithium-ion batteries and double-layer ultra-capacitors have amazing energy-storage capacities. However, the voltage of a single cell is usually not sufficient for higher power applications, and series connection is then required. Due to differences in individual cells some cells may experience different voltages. To compensate for variation in cell voltages and protect cells from over- or under-charging a charge equalisation circuit can be incorporated in the charge/discharge circuit (usually a DC/DC converter). This project will investigate different technologies and a prototype of the most promising one(s) must be constructed and tested.
This project requires the allocation of a long test bench.
