•
The traction battery cooling system consists of:
– four temperature sensors.
– a two-speed fan.
– a battery control module.
•
The cooling fan is located in the center of the traction battery.
•
The cooling function is controlled by the battery control module
(BCM).
•
During charging, the cooling fan is used for ventilation and
cooling of the traction battery:
– For ventilation, the cooling fan operates at low speed all the
time.
– For cooling, the cooling fan operates at high speed based on the
temperature of the traction battery.
– For ventilation purposes, the cooling fan operates for 10 minutes
following the completion of the charge cycle.
•
During driving, the cooling fan is used for cooling the traction
battery:
– For cooling, the cooling fan operates at high speed based on the
temperature of the traction battery.
– Air is drawn in from the rear of the traction battery and exits
through the front.
NOTE: Be sure vent openings are clear of obstructions before
connecting charger.
