1 USER MANUAL Multi-Functional Smartphone Terminal WCA NFC 2.0 2 3 1. System Description Continental Wireless Power Charger is developed for automotive applications under the name WCA NFC 2.0 which includes two functions like: o WPC: Wireless power charger; WPC Function 126.6kHz o NFC: Near Field Communication; NFC Function 13.56MHz The WCA NFC 2.0 module and its implementation inside the vehicle is depicted in Fig. 1. Its assembly instruction is done by professional workers. Therefore, the product cannot be moved or switched to another position by the end user. Fig. 1: WCA NFC 2.0 module and its implementation inside the vehicle WCA NFC 2.0 charger uses Qi standard of Wireless Power Consortium (WPC) for enabling wireless charging from a base station unit to mobile device. The power transfer method is based on near field magnetic induction between coils. 4 System Overview The structure of wireless power transfer proposed in Fig. 2 shows an overview of the system with two kinds of distinguished devices: Base station and Mobile device. Base station comprises two main functional units per mode (WPC and NFC), namely power conversion units and Communications & Control units for delivering, controlling and regulating the transferred power. Mobile device (power receiver) comprises a power pick up unit and a communications & control unit for achieving power requirements and charging the device battery if is chargeable device or establishing an active NFC communication. Fig. 2: Wireless power transfer structure: WPC and NFC 5 1.2 Wireless Power Charger Description The WCA NFC 2.0 is mainly composed of 6 parts as depicted in Fig.3. 1. Top housing 2. Antenna PCB 3.
