Description
Technical field
The present invention is about the power management techniques field, especially in regard to a kind of apparatus and method that show battery dump energy.
Background technology
Power management techniques is most important for the various battery powered apparatus that need, the electric weight deficiency can cause some equipment not to be driven and shut down, therefore the user need obtain the real time information of battery user mode, the dump energy information of battery particularly, and according to the normal operation of these information control apparatus.
In the prior art, on display screen, generally have a schematic diagram that shows battery dump energy, wherein comprise a plurality of status bars, when electric weight is full, each status bar all fills up, and when the electric weight slow consumption, the number of status bar can reduce successively, when electric weight exhausted, all status bars did not show.Fig. 1 has shown that battery electric quantity is from being filled to the overall process that exhausts.This display packing is the variation that shows electric weight on the one dimension direction.
Prior art one is come the dump energy of counting cell by adopting the method for measuring cell voltage, the basis of this method of measurement is: battery is (when being in holding state as mobile phone terminal) when normal consumption, exists corresponding relation between the magnitude of voltage of battery and the dump energy of battery.A kind of implementation of prior art one is: detect cell voltage; According to the cell voltage counting cell dump energy that detects; Detecting at least a inaccurate environmental factor of battery dump energy (as variations in temperature, self-discharge of battery amount etc.) that causes measuring comes the battery dump energy that calculates is proofreaied and correct.
Though prior art one adopts the measurement cell voltage to calculate and shows that the method for battery dump energy is simple, yet, this measurement result only when the battery normal consumption (being in holding state) as mobile phone reference value is arranged, when the battery normal consumption, dump energy and residue effective voltage are linear and descend.But, when battery during (as conversation, multimedia display or take pictures etc.) by load, because the caused pressure drop distortion of internal battery impedance, cell voltage will descend rapidly at short notice, but dump energy is not consumed a lot, this moment, measured cell voltage can not reflect real dump energy, as long as after the user stops using a period of time, the remaining battery effective voltage can recover again.As, after user's continued operation mobile phone, find that the battery compartment number has tailed off, after a period of time inoperation, the battery compartment number has increased again.Therefore, obtain battery dump energy and can cause measurement result and actual conditions inconsistent by measuring cell voltage: cell voltage is very low, but actual battery dump energy and much.
Prior art two is measured dump energy by the method for current integration, this method adopts current integration circuit to measure the electric weight that has consumed, deduct original electric weight that consumes power obtains dump energy, because this method is based on the real-time integration of electric current, the residual electric quantity of measurement is more accurate.A kind of implementation of prior art two is: by being connected on the resistance measurement battery discharge current in the battery discharge loop, discharging current is carried out time integral obtains the capacity that battery discharges, by battery be full of the specified electric quantity of electricity with discharged electric weight relatively come to determine dump energy in the battery.
Yet, two employings of prior art current integration method is carried out the electric weight demonstration can not make the user understand the current voltage of equipment, when the real surplus electric weight enough makes owing to cell load is heavier that still voltage decline is very fast, equipment can't be worked, the user only relies on the demonstration of dump energy can not predict the generation of this situation in advance, thereby usually is puzzled.When seeing that dump energy is enough, start a communication process as the cellphone subscriber, can not support this operation, may cause mobile phone shutdown when conversation this moment, influence user's normal use yet in fact the current voltage of mobile phone is very low.
