Thermistors are 2-leaded non-polarized devices. One lead of each sensor is to be connected to the
TPROBEn
pin of connector
J8
, where
n
denotes the channel on which that sensor’s signal is measured.
The other lead of each sensor is to be connected to one of the
VBOT_TEMP
pins of connector
J8
.
Unused temperature input wires should be properly insulated or removed.
3.7. Grounding and Fusing
The Battery Controller enables connection to a series-connected stack of monitored cells up to a
total voltage of 60V. The lowest potential (the negative end) of the connected stack also serves as
the common return for the contactor coils as well as the reference for the Battery Controller’s
internal circuitry and power supply. Any connection to earth or chassis ground must be made
outside of the Battery Controller.
The contactor coils return to the same potential as the most negative end of the
attached stack regardless of whether this point is connected to ground.
An earth or chassis ground connection may be made to any single point in the connected cell stack
as required by the application. The cell stack may also be left isolated from earth or chassis.
Fusing of the cell stack where it connects to provide operating power to the Battery Controller is
required externally.
Figure 12. Connection example for powering the Battery Controller from cells
If the load side of the current shunt is grounded:
• A fuse is required at the negative power connection point only, in line with the connection to
pin 6 of the
J6: Contactors / -V Power
connector
