CHARGING METHOD, MOBILE DEVICE, CHARGER AND CHARGING SYSTEM Russian patent published in 2017 - IPC H02J7/00 

FIELD: radio engineering, communication.

SUBSTANCE: embodiments of the present invention relate to a charging method, a mobile device, and a charger. The mobile device contains a battery and a connector. The connector contains a charging terminal and a ground terminal; and, when the charging terminal connects to the output terminal of the charger by using a charging cable or a battery charging stand, the charging terminal receives the first current signal transmitted by the charger output terminal and transmits the first current signal to the anode terminal of the battery, and the charger comprises a charging circuit. The charger provides the first current signal by using a charging circuit in order to charge the battery. The mobile device further comprises an analog switch; when the charging terminal connects to the output terminal of the charger by using a charging cable or a battery charging stand, the analog switch connects the anode terminal of the battery to the charging terminal; and the charging terminal receives the first current signal transmitted by the output terminal of the charger and transmits the first current signal to the anode terminal of the battery by using an analog switch in order to charge the battery. The mobile device further comprises a charging circuit and a Universal Serial Bus USB port; when the charging terminal is disconnected from the output terminal of the charger, the analog switch disconnects the anode battery terminal from the charging terminal and the output terminal of the charging circuit is connected to the anode terminal of the battery by using the analog switch; and the input terminal of the charging circuit is connected to the USB port, receives the second current signal transmitted by the USB port. The second current signal is smaller than the first current signal and transmits the second current signal to the anode terminal of the battery by using the output terminal of the charging circuit and the analog switch in order to charge the battery.

EFFECT: charging the mobile device with a strong current with reduction of its heat losses.
