From the project

Repositorio con el diseño de un BMS y una batería como TFM

In the present Master’s Degree Final Project, a Battery Management System (BMS) has been designed and manufactured, as well as a modular battery configurable at different voltages and capacities, with the aim of being able to power isolated electronic systems such as devices for capturing eco-acoustic significance indexes. The electronic design of the different modules that make up the power supply and management system has been carried out, as well as the calculation and design of the battery based on lithium-ion cells and its mechanical structure. In order to be able to supply this system…
