It should be noted that：Similar label and letter represents similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it further need not be defined and explained in subsequent attached drawing in a attached drawing.
Referring to Fig. 1, it is a kind of flow chart for aerogenesis measuring method that present pre-ferred embodiments provide.Below will be right
Idiographic flow shown in Fig. 1 is described in detail.
Step S11, the battery for being provided with heating component is put into container and sealed, the container is provided outside cooling group
Part.
In the present embodiment, battery is various types of batteries that quick-fried spray possible occur, and the packaged type of battery is unlimited, example
Such as, battery can be cylindrical, square, Soft Roll type etc..The type and set-up mode of heating component can be a variety of, as long as can
Battery is heated, for example, heating component can be the heating mantle that can be set on battery, can be that can be wound in battery
On heater strip etc..Cooling component can have a variety of ways of realization, as long as can cool down to container, for example, cooling
Component can be air-cooled component, water cooling component etc., this is not restricted in the present embodiment.
Step S12, detects the first temperature value in the container of the sealing, is calculated in the container of the sealing
One gas flow.
In the present embodiment, the first temperature value is not worked in heating component, and battery is positioned in the container of sealing and does not send out
Temperature value during raw quick-fried spray in the container for the sealing that measurement obtains, first gas amount are to obtain the situation of the first temperature value in measurement
Under gas flow in the container of sealing that is calculated.First gas amount can be calculated in the following manner.
Obtain the pressure value in the container of the sealing and the volume of a container of the sealing.
Wherein, pressure value is not worked in heating component, and battery is positioned in the container of sealing and the feelings of quick-fried spray do not occur
Under condition, the pressure value when measurement obtains the first temperature value in the container for the sealing that measurement obtains, the volume of a container of sealing can
Think the given data for measuring obtain in advance.
According to formula P0V=n0RT0The first gas amount in the container of the sealing is calculated, wherein, P0To be described close
Pressure value in the container of envelope, T0For first temperature value, V is the volume of a container of the sealing, and R is normal for perfect gas
Number, n0For the first gas amount.
Step S13, controls the heating component to heat, so that the quick-fried spray of the battery.
Step S14, controls the cooling component to cool down the container of the sealing after the quick-fried spray of battery occurs, is examining
The temperature value in the container of the sealing after the quick-fried spray of battery occurs is measured when reaching first temperature value, hair is calculated
Second gas amount in the container of the sealing after the quick-fried spray of raw battery.
Pressure value in the volume of a container for obtaining the sealing and the container that the sealing after the quick-fried spray of battery occurs, root
Second gas amount is calculated in the volume of a container of the pressure value, the first temperature value and the known sealing that are detected when accordingly.
Wherein, occur the quick-fried spray of battery after sealing container in pressure value be after measurement obtains first gas amount,
Control heating component is heated to the quick-fried spray of battery, then controls cooling component to cool down, until the sealing after the quick-fried spray of battery occurs
Container in temperature value return to the first temperature value, then detect the pressure value in container at this time.The quick-fried spray of battery occurs
Pressure value in the container of sealing afterwards is returned to first for the temperature value in the container of the sealing after the quick-fried spray of battery occurs
The pressure value that measurement obtains during temperature value.
Container is made of the material for being not likely to produce deformation, thus after the quick-fried spray of battery occurs, volume of a container is still constant.

Amount, wherein, P1Pressure when being returned to for the temperature value after the generation quick-fried spray of battery, in the container of sealing to the first temperature value
Value, T0For first temperature value, V is the volume of a container of the sealing, and R is ideal gas constant, n1For the second gas
Amount.
Step S15, production during the quick-fried spray of the battery is calculated according to the first gas amount and the second gas amount
Tolerance.
Wherein, gas production during the quick-fried spray of battery subtracts first gas amount for second gas amount.
Ensure that and quickly draw measurement result, alternatively, after heating component is heated to the quick-fried spray of battery, in cooling group
First control heating component is stopped before part work, so that the temperature in the container for the sealing that quick-fried spray can will occur for cooling component
Degree is quickly reduced to the first temperature value.
It should be appreciated that by the setting of cooling component, the cooling of container more can be rapidly realized, by cooling group
The control of part enables the temperature in the container of the sealing of the quick-fried spray of generation to be more accurately and rapidly reduced to the first temperature value, into
And make it that the aerogenesis measurement used time is shorter, measurement result is more accurate.
Alternatively, step S12 is being performed, is detecting the first temperature value in the container of the sealing, be calculated described close
Before the step of first gas amount in the container of envelope, the method further includes：The cooling component work is controlled with to described
The container of sealing is cooled down.
Wherein, in the first temperature value in detecting the container of sealing first, cooling component work is first controlled to alleviate
Heating component vessel temp caused when working raises suddenly so that container can gently realize heating relatively, so as to carry
The security of high measurement and the service life for extending container.Alternatively, the first temperature value in the container of sealing is detected first
When, cooling component operation setup duration can be controlled, if more demanding to measurement efficiency, in order to reduce as far as possible to heating component
The influence of heating effect, first can control cooling component to be stopped before heating component start-up operation.It is if it should be appreciated that right
Measurement efficiency is of less demanding, more demanding to measurement security and container service life, can be in heating component operation setup
Cooling component is controlled to be stopped again after length.The present embodiment is not restricted this.
