Section 12.1.4: B2 Current and State of Charge
•
B2 current is provided by the current shunt inside the IMS
lithium battery enclosure.
•
B2 current will display positive amperage if the IMS is
running the auxiliary A/C compressor and/or providing
energy to the chassis (
i.e.
discharging the lithium
batteries).
•
B2 current will display negative amperage if the battery
is being charged by the engine or by shore power (
e.g.
charging the lithium batteries).
•
B2 current will read either positive or negative amperage
and should be disregarded when the system is connected
to B0.
•
State of Charge (SOC) is the remaining usable energy
contained within the lithium batteries. This value is
located next to the B2 current.
•
SOC is calculated using only B2. Neither B0 nor B1 is
factored into this percentage.
