1.1.4 WPC modes According to the Qi standard, a simple operational description of wireless power transfer can be summarized in two operational modes. The first mode with a defined burst sequence allows the base station to detect the mobile device Qi compliant. The second mode allows the power transfer from the base station to the mobile device. More details of each operational mode are presented below: 1.1.4.
1.1.5 WPC parameters Bellow in table 1, the technical parameters of the Continental-WLC-CEM00 charger are specified: Parameters Values Carrier frequency 108.7 kHz Frequency shift +-2 KHz Supply voltage 13.5V lead acid vehicle battery Voltage supply range 8V < Vbat < 16V Operating temperature range -20°C < Temp* < 40°C Output Power on Power receiver Max. 5W WPC chipset brand Discrete components designed WPC litz coil information A13 type according to Qi standard WPC litz coil gain @ 108.7kHz -113.
