7.1 BATTERIES SCREEN
Screens for showing battery data differ depending on how many current sensors are
connected to a certain battery.
If the battery is only connected to a voltage sensor (without current sensor), the
battery name, approximate state-of-charge (SOC) and current voltage are
displayed. The calculation of SOC takes some time, so it may not be shown
immediately after power-on.
Up to three batteries without current sensor can be shown on a single screen. If
there are more, they are divided to two or more screens.
If the battery is connected to a voltage sensor and a single current sensor (shunt),
some additional data are displayed: time to charge / time to discharge and electrical
current (amps). SOC can be calculated more accurately if a current sensor is
connected. Time to discharge is calculated by using an average consumption
during some period of time.
If there is more than one current sensor (shunt) connected to the battery (e.g. for
monitoring different consumers or generators, connected to the battery), their data
(amps) is also shown on the battery page.
Pico's algorithm for calculating state-of-charge (SOC) is not a simple Ah-
counter.
It is constantly monitoring battery current, voltage and temperature. These
data are compared to the internal battery model and its parameters are
constantly being adjusted so that the model fits to the actual data.
The algorithm needs some time to adjust the parameters (learning phase)
and it will improve accuracy during the first few cycles.
7.2 TANKS SCREEN
Tanks screen shows current level of connected and properly configured tanks. Up
to four tanks can be shown on a single screen. If there are more, they are divided to
two or more screens.
For each tank, you can find its name, graphical representation of the current level,
and numerical values of the current level as a percentage and as volume unit (liters,
gallons).
Depending on the selected tank types, they may be represented by different colors.
