Specific embodiment
Below by specific embodiment and combine accompanying drawing the application is described in further detail.Described in text
"front", "rear", "left", "right", " on ", D score with the laying state of the battery safety test device in accompanying drawing as ginseng
According to.
As shown in figure 1, the embodiment of the present application provides a kind of battery safety test device, including upper lid 10, nowel
Body 11, temperature sensor and pressure sensor, in addition may also include subtest element, such as air flow rate sensor
13rd, gas temperature sensor 14, flammability analysis device 15 and corrosion classsification device 16 etc..
Continuing with referring to Fig. 1, lower box 11 includes shell 110, inner casing 112 and packed layer (not shown), shell
110 and inner casing 112 typically there is very high intensity, resistance to elevated temperatures, thickness≤20mm, preferred thickness are 1～10mm.Shell
The 110 side wall 110b for generally comprising base plate 110a and arranging around base plate surrounding, inner casing 112 are removably disposed in shell
110 inside, wherein, depending on the base plate 110a intensity of itself, if the intensity of base plate 110a is relatively low, inner casing 112 can be the bottom of with, to support
Anti-impact force, if the intensity of base plate 110a is higher, inner casing 112 can also be the tubular structure of upper and lower opening, be directly placed at
On base plate 110a.Packed layer is filled between inner casing 112 and shell 110, and packed layer mainly has two effects, and the first is fixed interior
Shell 112, which two is that packed layer is designed as heat-insulation layer or cushion, to provide insulation and cushioning effect.Certainly, packed layer
The two functions can also be provided simultaneously with.
In order to resist impulsive force and high temperature, upper lid 10 is general also to have very high intensity, toughness and heat-resisting quantity, thickness
Degree≤10mm, 1～5mm of preferred thickness can be carried out by screw or other accessories between upper lid 10 and shell 110 removable
Unload fixation.Upper lid 10 is covered when needing and being tested, and is screwed, upper lid 10 just can be collectively forming with inner casing 112
The test space, can place battery core to be measured or module 20 in the test space.It is in order to fix battery core or module 20, empty in test
Between inside be further fixedly arranged on fixture (not shown), fixture using the material manufacture of high intensity, and can directly be fixed
On base plate 110a.
As shown in Fig. 2 first being fixed battery core or module 20 with fixture before testing, lid 10 is covered afterwards, and passes through spiral shell
Silk is fixed, forms the test space.Simulate the thermal runaway state of battery core or module 20 afterwards in the test space.Line parameter of going forward side by side is supervised
Survey.Impulsive force produced by thermal runaway can pass through inner casing 112, packed layer and shell 110 enters row buffering release, 112 meeting of inner casing
The impulsive force of maximum is born, in order to improve the ability to bear of inner casing 112, the horizontal cross-sectional profile of inner casing 112 is preferably round.I.e.
Just thus, inner casing 112 is in test process or may deform upon and damage, but as long as after a test inner casing 112 is taken out
And the part for more renewing, just can ensure that test device continues safe handling.
In the present embodiment, for the thermal runaway data test of battery core or module 20 has many aspects, it is therefore desirable to various
The testing element of type.Wherein, temperature sensor and pressure sensor are topmost testing elements, the inspection of temperature sensor
