<p>A first device including a battery, a first connector, a charging module, a sensing module, and a communication module. The first connector includes a power supply pin, a ground pin, two transmit pins, and two receive pins, and connects the first device to a second device. The charging module receives power from the second device via the power supply pin and the ground pin to charge the battery and supplies power from the battery to the second device via the power supply pin and the ground pin. The sensing module senses the power supply pin and the ground pin of the first connector and detects when the first device (i) connects to the second device via the first connector and (ii) disconnects from the second device. The communication module communicates with the second device via the two transmit pins and the two receive pins using a PCIe protocol.</p> |
