SC8: Lithium–ion battery controller
The eTriFlex 3370 uses a Lithium–ion battery controller or Battery Management
System (BMS) to manage the lithium-ion batteries. Each of the eight lithium-ion
batteries communicates with the BMS through a sub-net via the battery interface
harness. The battery interface harness includes a 4-pin connector at each of the
batteries and a 9-pin connector at the BMS. The BMS uses the sub–net to verify
the presence and condition of each of the batteries before allowing battery power
to the machine. The BMS is also connected to the CAN bus which allows it to
forward battery information to the rest of the machine. The BMS is located under
the hood attached to the back of the center mounted batteries.
The Lithium–ion battery controller:
•
Monitors the batteries via a sub-net (battery interface harness).
Note:
All of the battery interface harness connections must be corrosion
free and securely connected before machine operation can occur.
•
Protects the batteries from operating (discharging and charging) outside their
safe operating voltage, amperage, and temperature ranges.
•
Operates an internal contactor to connect and disconnect the batteries from
the machine and the battery charger.
