NFC: Near field communication The WMI module and their implementation in different variants inside the vehicle is depicted in Fig. 1. D-WMI2020A Front console Fig. 1 : WMI module and WMI automotive implementation inside the vehicle WPC feature of the WMI uses Qi standard of Wireless Power Consortium (WPC) for enabling wireless charging from a base station unit to mobile device. - Page 3 information, the transmitter creates a power transfer contract containing the maximum power to be delivered to the load. 1.1.2.2 Charging mode After “Ping mode”, the power transfer starts. In this operational mode, the transmitter sends the carrier at a given level defined in the power contract in the operational “Ping mode”. The WMI controls the power transferred to the smartphone, in response to the control data messages sent by the smartphone.
