When the battery charger power switch is initially turned on, the charger ensures
that the charger bus voltage is at 0 V. If necessary, the charger discharges the
bus as a step in the start-up process. This is typical in the event that the charger
power is cycled O
FF
and then back O
N
.
Once the bus voltage is correct for start-up, the charger will wake the battery
pack. The battery pack runs some internal diagnostics, and if all is O
K
, the battery
main contactor closes. The charger will then send a signal on the CAN-bus
to stay connected to the battery pack. If the battery pack internal diagnostics
determine that all is not O
K
, the battery pack will send a fault message.
During start-up, the battery voltage, state of charge (as percent of fully charged),
and amperage will be displayed in the LCD message display.
