voltage
Linear charge controllers work like super fancy variable resistors, changing the resistance between the charger input and the battery terminal so that a specific amount of current flows. The current is usually measured with a current sense resistor, a resistor with small value (generally 0.01 to 0.5 ohms) that generates a small …
How does pulse or burp charging work?
Current must then be progressively reduced to stop the voltage from rising, and the battery gets charged slower and slower (taking 20 hours or more to get a full charge). AGM (Absorbent Glass Mat) sealed batteries get around this slow charging issue by recombining the hydrogen and oxygen rather than venting gas.
Battery State of Charge: Understanding the Basics
This method involves measuring the battery''s current and integrating it over time to calculate the total amount of charge that has been delivered to or withdrawn from the battery. This method is more accurate than voltage-based indicators, but it requires more complex calculations and monitoring of the battery''s current and time.
