Description
State of Charge indication
Used to generate pulse-width-modulated signal from 0 volts to total voltage
of Battery pack. When driving an analog fuel gauge the duty cycle of the
generated PWM signal is directly proportional to the estimated battery state
of charge

Configuration
Using EMUS BMS mini mobile application each pin can be configured individually and effortless:
•
In the main menu locate Configuration page
→
Pin Functions tab;
•
There will be all available input and output pins with programmable functions. Select a pin
which function you would like to change.
•
In the resulting drop-down window a list of all currently available functions for this pin will be
listed. Simply select new function and it will be automatically configured and enabled.
•
Each pin function has additional parameters: e.g. functionality inversion, input sensing type...
Therefore it can be additionally configured when needed.
Note!
Pay attention to input pin function sensing type. If input function is configured with Voltage
sensing it means pin is sensing high voltage, and if configured as Ground sensing - pin is sensing
ground (0 V). When input pin is configured for ground sensing, and high voltage is applied it will
result in damaging the interior components of this input pin.
