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

FIELD: electrical engineering.

SUBSTANCE: invention can be applied to electrical engineering. Method of charging control includes stages, at which: when charging operation begins, charging system is controlled so, that it is in first feedback state; and when charging system is in first feedback state, controlling feedback reception port so, that it is connecting with first power supply port according to first charging control device by means of first charging device switching device; and controlling second data signals transmitting port so, that it is connected with microchip data port according to second charging control device by charging terminal second switching device; determining, wether charging operation duration exceeds preset time delay or not; and when charging operation duration exceeds preset time delay, charging system is controlled so, that it is in second feedback state; and when charging system is in second feedback state, controlling feedback reception port so, that it is connecting with first data signals transmitting port according to first charging control device by means of first switching device, and controlling second data signals transmitting port so, that it is connecting to voltage input port according to second charging control device by second switching device.

EFFECT: technical result is elimination of voltage drop at USB wire between terminal and charging device.
