Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 is a schematic flow chart of a method for testing power of a low power consumption device according to an embodiment of the present invention, as shown in fig. 1, including:
s1, calibrating the voltage initial value of the equipment under the small load, wherein the initial value comprises a voltage value V and an interval V of the voltage valueregionWeight V of the voltage intervalweight；
S2, collecting discharge voltage under heavy load and corresponding electric quantity interval V according to preset time intervalcurrentAnd according to said VcurrentAnd the current electric quantity VupIs greater thanAnd adjusting the voltage intervals and the weight values corresponding to the intervals according to the small relation so as to evaluate the electric quantity of the equipment.
It can be understood that, in the embodiment of the present invention, the electric quantity of the device is effectively evaluated by adjusting the voltage intervals and the weight values corresponding to the intervals, and combining with the operation weight under a large load, specifically, in step S1, the device uses the ADC to collect the value of the battery voltage to calibrate the initial value of the device, in the embodiment of the present invention, a large load refers to a single maximum power consumption function when the device is in operation, and a small load: the single minimum power consumption function when the equipment runs is referred to.
Specifically, when the device is powered on for the first time, the voltage under the low load of the measuring device is V, and then the voltage interval V where the voltage is located is calculated according to the voltage VregionThe voltage interval can be generally divided into Vregion1，Vregion2，Vregion3 the following three conditions can be expressed as: vregoion e { V ∈ [)region1，Vregion2，Vregion3} according to the voltage interval VregionThe value of (A) can further calculate the voltage interval weight VweightCorresponding Vweight∈{Vweight1，Vweight2，Vweight3}. Suppose Vregion1 corresponds to the electric quantity VcurrentReporting the electric quantity value V for the first timeupIs equal to VcurrentThe current running weight is VtogetherEqual to 1.
Further, in step S2, voltage acquisition is performed with a fixed time interval T during heavy-load discharge of the battery, and each time heavy-load discharge, V, is acquiredtogetherSelf-adding once. Large load discharge V in time less than TtogetherAnd is not changed. The criterion for the voltage measurement when a large load is discharged is then mainly based on said VcurrentAnd the current electric quantity VupThe voltage intervals are adjusted according to the size relationship between the voltage intervals and the corresponding weighted values of the voltage intervals, and the electric quantity value is determined according to the redistribution conditions of the weighted values and the voltage intervals.
The following describes the electricity quantity testing method by a specific example, for example: when the heavy load is frequent, the running weight accumulation is accelerated, and the electric quantity is displayedThe adjustment time is shortened, the electric quantity change is reflected in time, when the frequency of a large load is reduced, the operation weight is reduced, the electric quantity adjustment time is prolonged, at the moment, the power consumption of equipment is low under the condition of a small load, the voltage is suddenly jumped, and the electric quantity conversion V cannot be changedcurrentThe value of (c).

If VtogetherIs less than VweightThen the power of the equipment is still VupIf V istogetherIs greater than VweightThen, the voltage interval and the weighted value corresponding to each interval are redistributed, and V is calculatedcntAnd (6) clearing.
It will be appreciated that viewing said VcntmaxWhether or not V appears continuously in the valuecurrentIs not equal to VupTwo situations can occur, one is at a continuous VcntOccurrence of V within the valuecurrent！＝VupIf so, remapping the voltage interval, reassigning the weight and assigning VcntZero clearing, VtogetherAnd (6) clearing.
In another case, V does not occur continuouslycurrentIs not equal to VupThen V is observedtogetherWhether the accumulated value is large or notAt the current VweightIf less than, the electric quantity is still VupOtherwise, remapping the voltage interval, re-assigning the weights and assigning VcntZero clearing, VtogetherAnd (6) clearing.
