State of Health measuring of NiMH batteries using simple electronic components.

Sammanfattning: The possibility of measuring the state of health of a NiMH battery without doing it in a lab is evaluated, the goal was to see if it was possible to perceive any differences between batteries of different states of health and whether it’s worth further exploring this solution in a more detailed manner. In order to try and extract and analyze the state of health of the batteries a series of tests consisting of discharging batteries at different lengths of times and different resistive loads were made, the voltage of the batteries being captured by a multimeter. The study shows that getting the state of health of a battery with simple components is a possibility and is useful for battery-powered items. Situations where batteries can’t deliver enough energy for the item to function can be prevented by measuring the health of the batteries and then subsequently switching out the batteries if needed.
