IMS2, IMS3, IMS4, IMS5 Operator Manual
Section 12.1.3: B1 and B2
B1 represents the IMS's 12V lithium batteries.
•
B1 is displayed in place of B0 when the 12V lithium
batteries are connected. If B1 is displayed, B0 is no longer
being monitored.
•
B1 will be connected with the engine running if the
charging logic has determined that the 12V lithium
batteries need to be charged (via the chassis alternator).
•
B1 will be connected when Idle Mitigation Mode is
engaged unless the hybrid disconnect is pressed.
•
B1 will be connected after the lead-acid batteries have
been charged for 30 minutes. When the lithium-iron
batteries have remained at or above 98% SOC for one
hour, or when they have been charged for six hours, the
charging will switch back to the lead-acid batteries.
B2 represents the batteries (whether switching or
non-switching) that provide energy for the A/C compressor,
external motor, battery equalizer, etc.
•
B2 is always displayed on the primary information screen.
•
B1 and B2 are in parallel any time the voltage is 12V
nominal.
