How to view the output current of the battery cabinet

How does a battery monitor work?

The battery monitor continuously measures the current flow in and out of the battery. Integration of this current over time, if it was a fixed current, boils down to multiplying current and time and gives the net amount of Ah added or removed. For example, a discharge current of 10A for 2 hours will take 10 x 2 = 20Ah from the battery.

What does a positive current mean on a battery monitor?

This is the current needed for DC loads. A positive current means that current is going into the battery. This is current coming from charge sources. Keep in mind that the battery monitor will always indicate the total battery current, being the current traveling into the battery minus the current traveling out of the battery.

What are the parameters of a battery monitor?

These parameters are called: Charged voltage - the float voltage of the battery charger. Tail current - a percentage of the battery capacity. Charged detection time - the time in minutes. As soon as these 3 parameters have been met, the battery monitor will set the state of charge value to 100%, thus synchronising the state of charge. Example:

What determines the effective capacity of a battery?

To complicate matters, the effective capacity of a battery depends on the rate of discharge, the Peukert efficiency, and, to a lesser extent, the temperature. And to make things even more complicated: when charging a battery more energy (Ah) has to be ‘pumped’ into the battery than can be retrieved during the next discharge.
