Battery charger BC1
D01001-02 4
LED Indicator
RED LED shows that the battery is in initial charging phase.
YELLOW LED shows that the battery charger has reached 80% of charge.
GREEN LED shows that the battery has reached 100% of charge.
Further information can be found in the description of the Charging Curve.
Example: the RED LED on blinking indicates a constant tension phase.
Alarms
The flashing LED shows that an Alarm situation has occurred:
Condition Alarm Type Description (Action)
GREEN flash Timeout
Phase 1 have a duration in excess of the maximal
allowed. (Verify the battery capacity).
RED-YELLOW flash Battery Current
Loss of output Current control. (Failure of the control
logic).
RED-GREEN flash Battery Voltage
Battery not in conformity (verify the nominal voltage)
or loss of output Voltage control. (failure of the control
logic).
RED-YELLOW-GREEN
flash
Thermal
Overheating of semiconductors. (Verify the fan
operation).
YELLOW-GREEN flash Selection
An unavailable configuration has been selected
(Verify the selector’s position)
When there is an alarm the battery charger stops supplying current.
Battery
A battery is characterised by two sizes: tension and capacity.
Tension:
Each element has a nominal tension, which depends on the type of battery (no
matter what size).
In order to reach higher tension, many elements are connected in series, so
creating a “BATTERY” of elements.
The number of elements is calculated by dividing the nominal tension of the
battery for the tension of each single element in the table:
Capacity:
It is the quantity of electric charge that the batteries can supply to an external circuit before the tension
decreases under the final limit value and it is obtained by multiplying the intensity of the discharging
current I, expressed in ampere (A), for the discharging time t expressed in hours (h): C = I x t
The traction battery capacity is normally referred to the discharging system of 5h: C5 = I x 5h.
The capacity values that can be recharged by the battery chargers can be found in the description of the
Charging Curve (this value is not present in the curves able to charge any capacity).
