3. NORMAL OPERATING MODE
3.1 Overview Of Parameter Readouts
In normal operating mode, the ePRO Plus can show you a wide range of important battery
parameters. Each parameter can be accessed by pressing the left or right arrow keys. The main and
most important parameter is the State of Charge (SoC) in %. This value will always be displayed
and is also linked to the round bar graph at the outer edge of the display. Additionally, the ePRO
Plus can show a second parameter at the bottom row of the display.
By default, the parameters voltage, current, time remaining and temperature are enabled
with temperature only shown when an optional temperature sensor is connected. Additional
parameters that are disabled by default are power and Amp-hours. The visibility of individual
parameters can be enabled or disabled through functions F9.0 to F9.8.
The default settings will allow the second parameter to only show for 120 seconds after the ePRO
Plus has been accessed. This will keep the display clean under normal conditions, which might
be preferred by less technical end users. Function F9.9 sets the second parameter auto hide time
and also o ers an option to always show the second parameter (auto hide =OFF).
Table 3 shows all available parameter readouts:
Table 3
State of charge (SoC) (%)
The SoC is the most important battery parameter. It
shows exactly how much charge is left in the battery.
This value is compensated for all known battery variables
(age, charge/discharge current, temperature etc.). 100%
represents a fully charged battery, while 0% represents
a completely at battery. Typically, you should recharge
a lead based battery when the SoC has dropped below
50%. For a lithium based battery, this level can be lower.
Main battery voltage (V)
Shows the voltage of the main battery bank connected
to the +B1 input.
