Next, the action to safety evaluatio experimental rig of the present invention shown in Figure 1 describes.
(1) as stated, after being arranged on Li ion battery module 2 in the chamber 1, lay the equipment of the safety evaluatio test that is used to the stipulate machine related etc. with it.
(2) power supply of connection exhaust equipment 50.
(3) connect the power supply of gas supply mechanism 10,13 etc.Thus, from pipe arrangement 3,4,5,6,7,8 air is supplied with in chamber 1, shown in the 3a of Fig. 2,4a, 5a, 6a, 7a, 8a, air roughly flows along a direction towards upper end side (with respect to the vertical direction of paper) from the lower end side of chamber 1.
(4) power supply of connection assist gas feed mechanism 30,31,32,33,34,35,36,37.Thus, from pipe arrangement 20,21,22,23,24,25,26,27 air is supplied with in chamber 1, shown in the 20a of Fig. 2,21a, 22a, 23a, 24a, 25a, 26a, 27a, air is along the madial wall rotation of metal side wall portion 1b and flow.
(5) flowing of above-mentioned (3) and (4) described each air is synthetic; Shown in the symbol ア that Fig. 3 representes; This resultant current flows towards upper end side along the madial wall rotation of metal side wall portion 1b and from lower end side, under this state, implements the safety evaluatio test of regulation.Thus; When the safety evaluatio test of carrying out said regulation; (for example comprise explosive composition gas from what Li ion battery module 2 produced; Hydrogen, ethene, methane) gas, and to the said gas that comprises explosive composition gas light a fire and the burning gases that obtain and from having of dispersing of said Li ion battery module 2 flammable and corrosive flying with the air of supplying with from gas supply mechanism 10,13 etc. or assist gas feed mechanism 30,31,32,33,34,35,36,37; Discharge from the gas output mechanism, this gas output mechanism comprises the L shaped pipe arrangement 40 that exhaust equipment 50 is connected with peristome with metal upper end 1c.
Therefore; Through the safety evaluatio test that Li ion battery module 2 is stipulated; And can realize following safety evaluatio experimental rig: even when producing a large amount of said gas that comprises explosive composition gas, it is excessive withstand voltage that chamber 1 does not need yet, and the said gas that comprises explosive composition gas can not remain in the chamber 1 yet; Even under the situation that the said gas that comprises explosive composition gas is lighted a fire; Can be safely burning gases be discharged, and flammable and corrosive flying can not be attached to the internal face etc. of chamber 1 from having of dispersing of said Li ion battery module 2, can not cause bad influence to test next time yet.
Need to prove; Safety evaluatio test as said regulation; Implement in the following test at least any, these tests comprise: pin prick test, vibration test, rotation test, shock test, compression test, overcharge test, over-discharge test, uneven charging test, Insulation Test, height test, humid test, vibration test, external short circuit test, partial short-circuit test, reversed charge test, bump test, forced electric discharge test, drop shutter test, discharge and recharge test, accumulation test, heat run, thermal shock test, burning test, anti-UV test, anti-ozone, moisture resistance test, immersion test, field investigation unusually.
In addition; In this execution mode; As the electrical storage device group; With Li ion battery module is that example is illustrated, but is not limited thereto, also can be with the module of the module of the module of secondary cells such as Li ion battery assembly, Ni-MH battery or assembly, electrolytic capacitor or double-layer capacitor or capacitors such as assembly, lithium-ion capacitor or assembly as object.
Need to prove; In this execution mode; Explained from gas supply mechanism 10,13 etc. and assist gas feed mechanism 30,31,32,33,34,35,36,37 air fed examples; But be not limited thereto; Even following structure; Also can realize the purpose that the application invents, this structure is: the gas that comprises explosive composition gas that produces from Li ion battery module 2 in safety evaluatio when test of carrying out said regulation, and to the said gas that comprises explosive composition gas light a fire and the burning gases that obtain and from having of dispersing of said Li ion battery module 2 flammable and corrosive flying and the air of only supplying with from gas supply mechanism (for example, from the lower end side of chamber 1 towards upper end side; Roughly along a direction flow air) together, the structure of discharging from the gas output mechanism that is arranged on chamber 1 upper end side.But,, can further improve and prevent that from having of dispersing of said Li ion battery module 2 flammable and corrosive flying is attached to the effect of the internal face of chamber 1 etc. through further setting up the assist gas feed mechanism.
In addition, in this execution mode, the lower end side that gas supply mechanism is arranged on chamber 1 has been described, and the gas output mechanism has been arranged on the example of the upper end side of chamber 1, but be not limited thereto.Promptly; As long as be following structure; Just can realize the purpose that the application invents; This structure is: possess for a distolateral distolateral gas supply mechanism of said chamber and another the distolateral gas output mechanism that is arranged on said chamber of being arranged on towards another distolateral supply gas in chamber; In safety evaluatio when test of carrying out said regulation, the gas that comprises explosive composition gas that produces from said electrical storage device group, and to the said gas that comprises explosive composition gas light a fire and the burning gases that obtain and from said electrical storage device group disperse have flammable and corrosive flying with the structure of discharging from said gas output mechanism from said gas supply mechanism gas supplied.And, in this execution mode, the example of air being supplied with in chamber 1 from pipe arrangement 3,4,5,6,7,8 has been described, but has been not limited thereto.For example, can be to make air pass through sieve and various structures such as in chamber, supply with.
In addition; In this execution mode; As from gas supply mechanism 10,13 etc. or assist gas feed mechanism 30,31,32,33,34,35,36,37 gas supplied, used air, therefore have the advantage that lack of air can not take place when in chamber 1, making the completing combustion of electrical storage device group.And, in this execution mode, be that example is illustrated with the air, but be not limited thereto, so long as combustion-supporting property gas just can play same action effect.
