Is a hall effect sensor the same as a hall effect current transducer but with a current sense?

I mainly want to know the difference between a Hall effect DC current transducer (which is different from a regular AC transducer) and a hall effect sensor (I assume that both of those differ from a ...

SLA battery under load: Is the absolute voltage or the state of charge primary for wear avoidance?

When an SLA battery is under load, they say not to go below a certain value to avoid wear. So, don't go under 30% State of Charge (SoC), which is also a certain Open Circuit Voltage (Voc), say 11.8V . ...

Can you monitor the state of charge of lead-acid batteries through their terminal voltage if they're being used?

Lead-acid batteries have -approximately- linear discharge curves and are therefore more easily monitored through their open-circuit voltage. Is there a way to monitor their SoC without disconnecting ...

Is there a relativily simple way to determine state of charge (SoC) for LiFePO4 batteries?

I'm searching for information regarding this matter and I can only find academic papers. I am wondering if anyone knows of any (more accurate or less accurate) way to evaluate the state of charge for ...
