Descripción
Este proyecto presenta el diseño, simulación e implementación de una plataforma experimental para evaluar estrategias de ecualización activa en baterías de litio.
La plataforma permite:
- reconfigurar dinámicamente el conexionado de celdas mediante una matriz de switches
- validar resultados mediante simulación y prototipo físico
El objetivo es contar con una plataforma para comparar distintas arquitecturas de balanceo y analizar su eficiencia energética.

Questions
How big is the Prototipo PCB?
It measures 188.4 × 185 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prototipo use?
189 parts, built around the MMBT2222A, 1N4736A, IRLB8721PBF and MMBT2907A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Prototipo KiCad files?
From the DeniseViltes/Tesis repository on GitHub, at the commit this page was made from: the board is hardware/PCB/prototipo.kicad_pcb and its schematic hardware/Circuito Final/Circuito externo/Circuito Final - Circuito externo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prototipo design in my own project?
Its repository states no licence, so its author keeps all rights: ask DeniseViltes before reusing the design.
