The corrections have been made to Section 5 Conclusions, and this section should be updated as follows.

A preliminary version of this work was published in Spanish in [30]. The present work is an extended version with the following improvements: a deeper review of the state of art is made; all devices have been integrated onto a PCB board instead of a breadboard; additional functionalities have been incorporated, such as battery voltage measurement (acting as the load), as well as a discharge circuit with corresponding new schematics; measurements were compared with those obtained from a high-performance commercial tracer, using it as a reference to assess the measurement error; the sensor has been calibrated for both voltage and current magnitudes; new experiments have been performed where ripple was observed, with explanations provided for this phenomenon.

The authors state that the remaining scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
