Other battery parameters

The following are the parameters that appear on the first page of the GUI, as shown in

Figure 36.

●

Battery parameters: it is possible to read and write the value of:

–

Maximum SOC at which the battery is assumed to be fully charged entered here in

percentage of “battery total capacity” (defined under key battery parameters).

–

Battery min. voltage defines the cut-off voltage below which the battery is

assumed to be empty and the external load is disconnected and indicated by LED

D2 glowing.

–

Battery min. SOC corresponding to SOC at battery nearly empty (%).

–

System parameters: it is possible to read and write various parameters like battery

relaxation time (battery relaxation time before OCV measurement in seconds),

battery low current (relaxation timer current threshold, i.e battery max. discharge

current for OCV measurement), application min. current (minimum application

current consumption in mA (<0)), charging end current (end charge current in mA),

charging min. current (min. charge current in mA).
