MOBILE TERMINAL AND LOAD POWER MEASURING METHOD THEREOF

摘要

A mobile terminal and load power measuring method thereof are provided in the present invention, wherein the mobile terminal contains a power source management module, a load to be measured and a power measuring module. An output end of the power source management module is connected to an input end of the load to be measured, and a measuring voltage output by the power measuring module is higher than a work voltage output by the power source management module. During the measuring course of the embodiments of the invention, the power measuring module supplies power for the load to be measured, and the measuring voltage at which the power measuring module supplies power for the load is higher than the work voltage output by the power source management module, so that the output current of the power source management module is cut off, and it is convenient to measure the real-time power of the load to be measured of a product, thus no voltage division or current division is redundant, and the power measuring result is exact; after the end of the measuring, the power measuring module can shut off the load power supply, and the power source management module continues to supply power, so as to stop the work of the power measuring module or turn off the power measuring module, and reduce the consuming energy of a system; during the whole measuring course, the normal work of the load is not effected.
