Shunt
Type
System Configuration Proposed Controller Operation
All battery management features shall
be available.
Shunt input may or may not be
connected to a shunt located in the
system. There are no “Shunt Monitors”
configured in the system. Controller shall report the following:
I
Load
= Σ I
Rect
I
battery
= Unavailable
NONE
Shunt input may or may not be
connected to a shunt located in the
system. System has Shunt Monitors
configured in the system.
Note: even if not being used and
centralized shunt must be mounted in
the grounded side of the system’s DC
bus. Possible damage may occur if the
shunt is connected incorrectly. 1. If cards are configured to monitor
“Battery” shunts, it shall be
assumed that all battery current
flows through these shunts to and
from the system batteries and shall
be summed to be equivalent to the
total battery current ( I
battery
).
2. Cards configured as monitoring a
“Load” shunt shall not affect the
total I
Load
but have their values
individually displayed.
Thus, the controller shall report the
following:
I
battery
= Σ I
battery shunt monitors
I
Load
= Σ I
Rect +
Σ I
battery shunt
monitors
Where I
battery shunt monitors
is negative for
current into the battery and positive for
current out of the battery.
Note: If there are no Shunt Monitors
configured as battery then:
I
battery
= Unavailable
I
Load
= Σ I
Rect
Shunt input may or may not be
connected to a shunt located in the
system. System has Shunt Monitors
configured in the system and all system
loads are monitored.
And
The new “All Load Monitored” feature
has been “Enabled”.
1. Cards configured to monitor
“Battery” shunts are assumed to
monitor all battery current to and
from the system batteries and shall
be summed to be equivalent to the
total battery current ( I
battery
). In
addition, all individual battery
monitor values shall be displayed
2. Cards configured as monitoring a
“Load” shunt shall be summed to
calculate the total I
Load
and also
have their individual values
displayed.
Thus, the controller shall report the
following:
I
battery
= Σ I
battery shunt monitors
I
Load
= Σ I
Load shunt monitors
Note: If there are no Battery Shunt
Monitors configured but the total load
