10.3.3 There is a current reading while no current flows

Perform a zero current calibration while all loads are turned off (paragraph 7.1.13) or set the current threshold
(paragraph 7.1.8).

10.3.4 Incorrect state of charge reading

Incorrect state of charge due to a synchronisation issue
State of charge is a calculated value and will need to be reset (synchronised) every now and then. The following
parameters will have an effect on the state of charge calculations if they have been set up incorrectly:
• Battery capacity
Charged voltage and tail current
•
Peukert exponent and charge efficiency factor
•
State of charge and synchronisation settings
•
For more information on these parameters see paragraph 7.1: "Battery settings".
Also see next paragraph 10.3.5.: "State of charge indicates three dashes "---"".
Incorrect state of charge due to incorrect current reading
State of charge is calculated by looking at how much current flows in and out of the battery. If the current reading
is incorrect, the state of charge will also be incorrect. See paragraph 10.3.2.: "Incomplete current reading".

10.3.5 State of charge indicates three dashes "---"

This means that the SmartShunt is in an unsynchronised state. This mainly occurs when the SmartShunt has just
been installed or after the SmartShunt has been unpowered and is being powered up again. Charge the batteries
and the SmartShunt should synchronise automatically. If that doesn't work, review the synchronisation settings,
See paragraph 5.3: "Synchronising the SmartShunt".
If you know the battery is fully charged but don't want to wait until the SmartShunt synchronises, then press the
Synchronise SoC to 100% button, see paragraph 7.1.12: "Synchronise SoC to 100%".

10.3.6 State of charge does not reach 100%

The SmartShunt will synchronise and reset the state of charge to 100% as soon as the battery has been fully
charged. Fully charge the battery and check if the SmartShunt correctly detects if the battery is fully charged. If
the SmartShunt does not detect that the battery has been fully charged you wil need to check or adjust the
charged voltage, tail current and/or charged time settings. For more information see paragraph 5.3.1: "Automatic
synchronisation".
State of charge does not increase fast enough when charging
Check if the battery capacity has been set correctly. See paragraph 7.1.1: "Battery capacity".
State of charge always shows 100%
