Ford Escape: Accessory Charging / Description and Operation - Wireless Accessory Charging Module (WACM) - Overview
The WACM is a 5 Watt wireless power transmitter certified under the
Wireless Power Consortium's Qi (pronounced “Chee") Standard. The WACM
can be used to energize the secondary receiver coil equipped in one Qi
compatible device (smart phone, wireless earbuds case, etc.) thereby
charging the device wirelessly. A list of Qi compatible devices can be
found on the WPCs website:
https://www.wirelesspowerconsortium.com/products.
The WACM is a powered at all time node from fused battery and
performs network management on HS-CAN3 . Wireless charging status is
provided as a CAN signal on the HS-CAN3 .
The BCM provides a protected switch to battery input to the WACM
when an interior passive key search is in progress to disable the
wireless charging feature. This is to prevent possible interference
with the passive key when placed in close proximity to the WACM during
the charge session of a secondary device. A redundant CAN signal is also
sent by the BCM in addition to the protected switch to battery input.
