Technical solution adopted by the utility model to solve its technical problems is：

A kind of intelligence USB data line, including data line, control device；The control device connects one by data line USB-TYPE-A types male connector and a USB plug；The control device is outer with window positioned at what is connect with data line outer surface In shell, the control device includes the control circuit board for being equipped with MCU and monitoring circuit with data line electrical connection, the MCU prisons Control circuit is equipped with the control module being connect with MCU, detection module, timer timing module, the display with liquid crystal display Module；The battery to be charged that the control module control is connected on USB plug electrically conducting and disconnecting；The detection module Detection is by the voltage of the operating current and operating voltage, battery to be charged of data line when energization, and by each electric current and voltage Information feeds back to control module；The timer timing module starts timing when battery to be charged electrically conducts；The display The liquid crystal display of module is in the window of the shell and shows the timing of timer timing module, passes through data line Operating voltage and operating current, the voltage of battery to be charged and charged state.

Preferably, the timer timing module is integrated with the timing module in MCU.

Preferably, the liquid crystal display show the electricity percentage for needing rechargeable battery, flow to electricity to be charged The charge capacity in pond.

Preferably, the USB plug is micro-B type male connectors.

The beneficial effects of the utility model are：Control device is set on data line, in the control circuit of control device When timer timing module and display module being set, timing is begun to when battery is charged by data line and showing timing Between and charged state, just automatically powered off more than after timing, be unlikely to make overcharging for battery pair.People pass through charging The charged state of the time and battery that need can accomplish effective management and control to charging, preferably protect equipment.
