Run a Battery Test Remotely
To run a Battery Test remotely:
1. Go to
System > FXM System > System Functions > Battery Test
.
2. From the Remote BT Configuration table, set Remote BT to Enabled .
3. Select a user input to trigger the
Battery Test
.
4. When the Trigger Input is active and the conditions for the battery test are met, Battery Test will
start to run.
Once
Remote BT
is triggered,
Battery Test
will continue to run even when the
Trigger Input
is
no longer active.
9.3.10 Configure Battery Runtime and Health Estimation
The
Battery Runtime and Health Estimation
is used to calculate
Estimated State of Charge,
Estimated Battery Health
and
Estimated Battery Runtime
.
Estimated Battery Health
is only
updated when the battery is discharged below 80% state of charge.
To configure Battery Runtime and Health Estimation:
1. Go to System > FXM System > System Functions > Battery Runtime and Health Estimation .
2. From the Configuration table, enable Battery Estimation .
3. Set the Load Model . The load model has no affect on calculating Estimated State of Charge or
Estimated Battery Health, but it has a significant impact on calculating the Estimated Battery
Runtime .
a. With the constant current model, the load current is expected to stay the same as the load
voltage decreases.
b. With the resistive model, the load current is expected to decrease as the load voltage
decreases.
c. With the constant power model, the load current is expected to increase as the load voltage
decreases.
4. Set the Battery LVD . Most FXM HP units do not have an external L ow Voltage Disconnect
(LVD) ; if this is the case, this setting can be left unknown.
9.3.11 Configure AC Shutdown
The AC Shutdown function is used to turn off the AC output. With the inverter turned off, neither the
inverter nor the AC line is supplying power to the load. The FXM will go to Shutdown mode. There are
two ways to turn off AC output: manually or with a triggering source.
