Abstract
In the era of energy transformation, the efficient storage of electrical energy is crucial. The most common form of energy storage is through batteries, which store electrical energy in chemical form. However, batteries must be continuously monitored due to their limited lifespan and the gradual decrease in their performance with the number of charge and discharge cycles. Central to assessing the condition of a battery is its ability to store electrical charge.
Since different electrical currents can flow during the discharging of the battery, the current components are continuously summed. The necessary technology for this can be relatively easily implemented using a microcontroller.
A possible solution for measuring different currents is presented here. An Arduino microcontroller system is used.
