Lithium-ion battery controller
The machine uses a Lithium-ion battery controller or Battery Management
System (BMS) to manage the lithium-ion battery. The lithium-ion battery
communicate with the BMS through a sub-net via the battery interface harness.
The battery interface harness includes a 4-pin connector at the battery and a
9-pin connector at the BMS. The BMS uses the sub–net to verify the presence
and condition of the battery 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 attached to the battery mount
inside the battery cover.
The Lithium-ion battery controller (BMS):
1. Monitors the battery via a sub-net (battery interface harness).
Note:
The battery interface harness connections must be corrosion free and
securely connected before machine operation can occur.
2. Protects the battery from operating (discharging and charging) outside their
safe operating voltage, amperage, and temperature ranges.
3. Operates an internal contactor to connect and disconnect the battery from
the machine and the battery charger.
Note:
When the key switch is set to the Off position, the BMS delays
disconnecting the battery from the machine for approximately 3 seconds to
allow time for all the other machine controllers to shut down.
4. Communicates battery information to the machine during operation via the
CAN bus.
5. Communicates battery information to the battery charger via the CAN bus.
6. Supplies battery pack signal voltage to the key switch.
Note:
Except for the lithium-ion battery cables, the only machine circuit with
voltage when the key switch is in the O
FF
position, is the low amperage signal
voltage (Pack Sig+) from the BMS to the key switch.
