T22 Mobile Device Wireless Charger Module

| Inductive charging, also known as “wireless charging”, uses a magnetic field to transfer energy between two objects.

The wireless charger has an induction coil to create an alternating magnetic field. A second induction coil in a p01table device takes power from the magnetic field and converts it back into electric current to charge the batte1y. The hvo induction

coils in proximity work similar as an electrical transformer.

K9 Body Control Module

| The module controls various vehicle functions like lighting, central door locking, power windows, etc.

The control module also reads various switches and sensors and makes their

values available via serial data.

The T22 Mobile Device Wireless Charger Module is controlled by an ignition operated relay and is operational when the ignition is in the Accesso1y or On position. When a wireless charging device is placed on the charging pad/pocket the charging of the device batte1y will start. The K9 Body Control Module detects the device batte1y is charging and sends a serial data message to the Pl 7 Info Display Module which illuminates the charge indicator.

DESCRIPTION AND OPERATION

MOBILE DEVICE WIRELESS CHARGER DESCRIPTION AND OPERATION

Mobile Device Wireless Charging System

• Fig. 15: Mobile Device Wireless Charging System Block Diagram

Courtesy of GENERAL MOTORS COMPAlNY

The Mobile Device Wireless Charging System (WCS) is an system for wirelessly charging mobile devices. It is capable of charging the batteries of compatible mobile devices. A compatible device is one that is compliant with Power Matters Alliance (PMA) or Wireless Power Cons01tium (WPC) Standard, meaning that it is equipped with a PMA or WPC wireless charge “receiver” that will work with the charge “transmitter” installed in the vehicle. The devices may utilize built-in charging circuitiy or an adapter (external plug-in device which contains the charging circuitiy). To check for phone or other device compatibility, refer to GM Total Connect.

WARNING : Remove all objects from the charging pad before charging your mobile device. Objects, such as coins, keys, rings, paper clips, or cards, between the phone and charging pad will become very hot. On the rare occasion that the charging system does not detect an object, and the object gets wedged between the phone and charger, remove the phone and allow the object to cool before removing it from the charging pad, to prevent burns.

Charging

To charge a device, place it on the charging surface in the vehicle. There is a charging coil located in the center of the charging surface. The device has a charging coil typically near the center of the device. These coils must be lined up in order for charging to proceed. When the intenuptible retained access01y power (IRAP) relay is closed (this is trne typically when vehicle ignition is in Run or Access01y position), the WCS will detect the device, establish communications with the device to confirm it is a compatible device, and then deliver charging power to the device via wireless interface. The WCS will be able to deliver up to SW of power to compatible devices. It shall only enter a charging state if communication is established and a compatible device is identified.

The WCS shall not enter a charging state if there is no communication established with a compatible device. If a non-compatible device or metallic foreign object is detected, the WCS will not ti·ansfer power. The charger monitors its internal temperature and will shut down if the charger temperature exceeds 185F (85C).

Indicator

The body control module will detect the device batte1y is charging and send a serial data message on the GMLAN bus to the radio display. The radio display will indicate a device is cunently charging. When the indicator is toggling on and off this indicates a thern1al limit has been reached and the device will not charge. For more infonnation refer to the infotainment owners manual.

Courtesy of GENERAL MOTORS COMPANY

The alternating cunent (AC) access01y power outlet system consists of the access01y DC/AC power inverter module and the accesso1y power receptacle – 110 V AC. The accesso1y DC/AC power inve1ter module conve1ts 12 V direct current (DC) batte1y power to 110 Vat 60 Heitz (Hz) AC power to operate AC powered devices. The access01y DC/AC power inve1ter module provides up to 150 watts of power. The accesso1y power receptacle – 110 V AC provides the usual connection for AC powered devices.

110 Volt Power Outlet Receptacle System Operation

The accesso1y DC/AC power inve1ter module receives fuse protected battery voltage and is connected to the 12 V electtical system ground. The access01y power receptacle – 110 V AC has an internal switch, that detects when an AC powered device is plugged into the outlet. When the ignition is ON, and an AC powered device is plugged into the access01y power receptacle – 110 V AC, the nonnally open switch in the accesso1y power receptacle – 110 V AC, closes. When the accesso1y DC/AC power inve1ter module detects the voltage from the accesso1y power receptacle – 110 V AC switch, the inve1ter module begins to supply 110 V AC to the accesso1y power receptacle – 110 V AC after a 1.5 s delay. The accesso1y AC power system is protected against circuit overload and circuit sho1ts to ground.

110 Volt Powe.- Outlet Receptacle I s olation Fault Protection

The accesso1y DC/AC power inve1ter module contains a ground fault circuit interrupter (GFCI). GFCI monitors the 110 V circuit for a sho1t to vehicle chassis ground. If a 110 V AC sho1t to ground is detected, the accesso1y DC/AC power inverter module will tum OFF. The module remains OFF, until the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 s delay.

110 Volt Powe.- Outlet Receptacle Overload Shutdown

The access01y DC/AC power inve1ter module will tum OFF if the current in the 110 V circuit is greater than 3.8 A for 1 s, or 2.5 A for 10 s. The module will tum ON again, when the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 s delay.

110 Volt Powe.- Outlet Receptacle Internal Shutdown

The access01y DC/AC power inve1ter module will tum OFF if the B+ supply voltage is greater than 16.5 V or less than 11 V. The module will also tum OFF if the device temperature is greater than 85.A°C (185.A°F). The module will tum ON again, after the shutdown condition is conected, and the AC powered device is unplugged from the outlet, and then plugged into the outlet
