Default Re: battery fan

the system contains and operation sensor that sends an output to the pcm/mcm to control fan speed and on/off. its what they call duty controlled so it doesnt come on at the same time all the time

IPU Module Fan
The battery module, MPI module, and DC-DC converter generate heat during assist/regeneration. The IPU is equipped with a fan to cool it down, assure proper battery performance, and protect the system. The fan has a control circuit and rotation sensor that are controlled by the MCM. The cooling air is drawn into the battery module from the top of the rear tray, then it is exhausted into the trunk compartment through the MPI module heat sink and the DC-DC converter heat sink.

The fan can be throttled into action by the BCM's reading of the pack's temperature sensors or by another downstream module (for example the MCM or the DC-DC).
On your HCH1 the battery threshold temp should be at 90C (194F). The absolute temp trigger point for the MCM should be at 100C (212F).
