1. 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.
Note: If the Lithium–Ion Battery Controller is replaced for any reason, the
machine software must be updated; contact an Authorized Toro Distributor for
assistance.
