Fuel gauge full
0-100%
Because every vehicle’s OEM gauges have
different scaling, these four parameters allow
the EVMS Core to tune it’s outputs to suit your
gauges. When these parameters are selected
for editing, the EVMS will drive the appropriate
gauge for the current parameter, allowing you
to tune the gauge visually. (Note that you may
need the key in the On position to power the
instrument cluster, but enter Setup first.)

Peukert's Exp
1.0 - 1.3
Allows adjustment of Peukert’s Exponent
so the EVMS can compensate for discharge
characteristics of different battery types. See
also section
Peukert’s Effect
.
Enable precharge
YES/NO
The EVMS Core’s internal precharge can be
disabled, but make sure your controller does
not require it or contactor damage may result!
Enable aux swch
YES/NO
If your contactors have auxiliary switches, turn
this setting on for monitoring the switch status.
BMS: Min voltage
0 - 5.00V
Adjusts the low voltage warning threshold for
each cell in your traction pack.
BMS: Max voltage
0 - 5.00V
Adjusts the high voltage warning threshold for
each cell in your traction pack.
BMS: Shunt voltage
3.00 - 5.00V
Adjusts the voltage at which shunt balancers
turn on for each cell in the tracion pack.
BMS: Low temp warn
0-100˚C
The EVMS can provide a warning if any BMS
modules report a temperature below or above
these respective thresholds.
BMS: Overtemp warn
0-100˚C
Stationary Mode
YES/NO
Switches the EVMS into Stationary Mode,
for battery backup and off-grid power type
applications. Please refer to the “Stationary
Applications” section for more information.
Current sensor
300A, 600A,
1200A
Selection of the current sensor size (as shipped
with your EVMS Core)
Display brightness
0-100%
Adjusts the brightness of the LCD display’s
backlight.
Buzzer On
YES/NO
Selects whether the Monitor should sound the
buzzer for alerts. (Safest to leave this on.)
Use Fahrenheit
YES/NO
Changes display of temperature units to
Fahrenheit instead of Celcius.
Error Detection
The EVMS monitors a wide range of operating parameters for your electric vehicle and can
notify you if any exceed their safe range or any faults are detected. In most cases, errors
can be acknowledged/reset by pressing the Select button. Critical errors are responded to
automatically (such as by shutting down the traction circuit due to a critically low cell),
while others are at the driver’s discretion to respond to (such as over-temperature warnings).
The following table describes the errors you may encounter.
Error
Description
Corrupt Settings
Occurs if memory corruption has been detected in the EVMS
Core’s saved settings (they will automatically be reset to
defaults). Contact us if you see this one.
Overcurrent warning
If battery current exceeds the programmed threshold for more
than 1 second, this warning will appear.
Overcurrent shutdown
As above, except the EVMS will also automatically shut down
the traction circuit if this threshold is exceeded.
Note that for
safety reasons this system cannot replace a real fuse, though it
can usually avoid blowing the real fuse.
BMS - low cell
A BMS module has reported a cell voltage below the minimum
threshold.
Shutdown by BMS
A low cell condition has been present for more than 10 seconds,
so the EVMS has shut down the traction circuit to protect the
batteries.
BMS - high cell
A BMS module has reported a cell voltage above the minimum
threshold.
Charge ended by BMS
A high cell condition has been present for more than 1
second, so the EVMS has shut down the charger to protect the
batteries.
BMS - overtemp
A BMS module has reported a temperature above the
programmed threshold.
Low battery charge
The battery’s State of Charge has reached the programmed
warning threshold.
Over-temperature
The EVMS Core’s temperature sensor has reported a temperature
above the programmed warning level.
