IoT battery health meter
Abstract
Estimating basic battery metrics, such as State of Charge (SoC) and State of Health (SoH), is crucial in determining whether a battery can recover and thus extend its life. This is particularly important in the context of their use in laptop computers, cell phones, among others, since the disposal of these batteries can lead to environmental contamination due to their toxic materials. To evaluate SoC and SoH, monitoring of voltage, current, and temperature during charge and discharge cycles are employed. If a battery shows a low SoH, it indicates significant degradation, it may not be suitable for further use. if the SoH is still relatively high, it might be possible to recover the battery. Battery recovery systems may involve processes such as deep cycling (discharging and recharging the battery multiple times), battery balancing (ensuring all cells have the same charge capacity), or applying specific charging algorithms to reactivate or improve battery performance.
