Intelligent Power Bank for Magnetometers

Aim of this thesis is to design and realize high capacity power bank powered by Li-Ion accumulators that provides charging including protection of those accumulators with possibility to inform user about available energy. Design of the facility means creation of schematic and circuit board including its soldering and writing firmware for used microcontroller. By realisation is meant getting the device to work.
Keywords: power bank, accumulators, microcontroller, STM32, charging

Second prototype of the powerbank’s electronics
PCB with description
First PCB – we had troubles with the TI BQ40Z60 circuit – the manufacturer does not provide sufficient amount of information to make it work properly (missing registry descriptions, operation flowcharts…)
