C(tn)=C (t0)-∫i(t)dt
Wherein, t is current discharge time, t0For initial time, tnFor current time, C (t0) it is initial quantity of electricity, C (tn) be
Electricity at present, i (t) are discharge current.When battery charges, minus sign is changed to plus sige.
In method for the present invention, as pass through initial quantity of electricity C (t0), and when in above-mentioned steps by default test
Between the total power consumption C that calculate of t obtain, dump energy C (tn)：
C(tn)=C (t0)-C
=C (t0)-∫(ia-ib)dt
And calculate dump energy up time t '：
A kind of terminal power measuring system, including：
Acquisition module, for obtaining real-time current；
First computing module, for the real-time power consumption of computing terminal, obtain total power consumption of terminal in the default testing time
Amount；
Second computing module, for reading current electric quantity, calculate remaining runtime.
