AB The purpose of this final degree project is the design of a first prototype of abattery management system to be used in the future in the electric vehicle that isbeing built by students from the University of La Laguna. The vehicle is beingbuilt within the FSULL dynamics project to compete against other vehicles in thiscategory developed by other universities.The purpose of a battery management system is to try to optimize the amount ofenergy stored in a pack in addition to ensuring the integrity of the cells that makeit up. To do this, it monitors the voltages of each of the series present, in order tomake sure that each of them is within the safe voltage values declared by the cellmanufacturer. To optimize the load, what it does is balance the voltages, that is,once the voltages are measured, it looks at the differences between each series,and if a serie has more voltage than normal, it balances it with respect to theothers in different possible ways. , depending on the bms topology.In the case of this design, it is a passive battery management system, whichmeans that the balancing is done by short-circuiting the series to be dischargedwith a resistance to transform the excess energy into heat. In addition, itsstructure is such that you can have as many series as you want because it is basedon modules capable of monitoring up to 12 series that communicate with amaster via CAN bus, which makes it completely modular. External power is notrequired as the slaves are fed directly from the pack that balances. However themaster must be powered via a low voltage battery up to 24V.
