Tether and connect on the module frame 203 to be formed, relatively, needs arrange corresponding through hole 9 on module frame side plate 2031.Temperature control inducing QI
The opening 4 of first the 2, second opening of opening the 3, the 3rd and the shape of wire lead-out groove 5, position, number and chi that device 202 has
It is very little arbitrarily to adjust as needed, it is for instance possible to use the setting in such as Fig. 5 a to 5e, will not be described here.
Fig. 9 shows the structural representation of battery modules 300 according to embodiments of the present invention.Battery modules 300 include：It is many
Individual cell 301, temperature control gas operated device 302 and module frame 303 and explosion-proof gas operated device 304.With the electricity shown in Fig. 1 and Fig. 5
The difference of pond module 100 is at least that battery modules 300 also include explosion-proof gas operated device 304.For the sake of clarity, it is main below
Difference part is described.
In certain embodiments, multiple cells 301 each have explosion-proof valve, and being provided for for explosion-proof valve will be because of monomer
The too high gas that sprays of inner pressure of battery discharges cell.When its Producing reason mostly is temperature rising, the work inside battery cell
Chemical reaction between property material, this gas mostly is high-temperature gas, according to the difference of electrolyte component in battery cell, this height
Wet body is also possible to produce danger, and affect battery uses safety.
As shown in figure 9, explosion-proof gas operated device 304 covers the explosion-proof valve of multiple cells 301, be arranged on it is described
The corresponding position of explosion-proof valve, makes the gas that the gas sprayed from explosion-proof valve enters explosion-proof gas operated device 301 import opening 3041
And for the gas for going out the explosion-proof valve to be discharged the gas outlet opening 3042 of explosion-proof gas operated device 304.Gas is imported
Opening 3041 can be arranged to an opening towards row's explosion-proof valve.Gas imports shape, position and the quantity of opening 3041
Can arbitrarily arrange as needed, for example gas imports opening 3041 can be arranged to multiple, and each gas imports opening 3041
Corresponding to one or more explosion-proof valves.Gas outlet opening 3042 can arrange one, it is also possible to arrange multiple, as needed may be used
So that gas outlet opening 3042 is arranged at into setting regions, such as both ends or one end of explosion-proof gas operated device 304.
In certain embodiments, temperature control gas operated device 302 and explosion-proof gas operated device 304 are integrally formed, certain temperature control inducing QI
Device 302 and explosion-proof gas operated device 304 can also be independently arranged.Figure 10 shows temperature control gas operated device and explosion-proof inducing QI in Fig. 9
The example of the integrally formed structure of device.As shown in Figure 10, the temperature control gas operated device 302 of two of battery modules 300 can be with
Explosion-proof gas operated device 304 is connected with each other by cylinder connector 10.But the connected mode shown in Figure 10 is not limited to, each control
