In view of this, the utility model discloses a put the battery and test in explosion-proof box, effectively avoid the battery to receive the inside short circuit that outside mechanical strength arouses and lead to too much energy release, prevent that the lithium cell from taking place conflagration and casualties because of thermal runaway battery fires the burning, compare in prior art the security that has improved the battery test.

The utility model provides a be applied to explosion-proof protection device of lithium battery test, it includes the box, and top cap detachably installs in the top of box, and a plurality of first through-holes have been seted up to the lateral wall of box, and the bottom of box is provided with battery location portion, has placed the battery in the battery location portion, and the insulating layer is fixed to be laid on the inner wall of box.

The utility model provides an among the explosion-proof protection device for lithium cell test, through testing the battery in the explosion-proof box, effectively avoid the battery to receive the inside short circuit that outside mechanical strength arouses and lead to too much energy release, prevent that the lithium cell from taking place conflagration and casualties because of the thermal runaway battery burning of starting a fire, compare in prior art the security that has improved the battery test.

Therefore, compared with the prior art, the explosion-proof protection device applied to the lithium battery test of the embodiment mainly has the following advantages:

1) the safety of battery testing personnel is guaranteed.

2) Sufficient safety guarantee can improve battery research and development speed to a certain extent.

3) Simple structure and low cost.

Furthermore, at least two side surfaces of the box body are respectively provided with a second through hole, and at least two connecting ends of the top cover penetrate through the at least two second through holes.

In the explosion-proof protection device applied to the lithium battery test, as a further scheme, the top cover is more explosion-proof in a cross-under mode than the traditional hinge mode.

Furthermore, the top cover is a rectangular top cover, two opposite side surfaces of the box body are respectively provided with a second through hole, and two opposite ends of the top cover are respectively arranged in the two second through holes in a penetrating manner.

In foretell explosion-proof protection device who is applied to lithium cell test, as further and more specific scheme, the rectangle top cap just need open two through-holes and just can accomplish to wear to establish fixedly, practices thrift manufacturing cost

Further, the box is a rectangular box.

In the explosion-proof protection device applied to the lithium battery test, as a further scheme, the rectangular box body is easy to produce and is matched with the shape of the rectangular top cover.

Furthermore, a plurality of first through holes on the side wall of each rectangular box body are arranged in an array.

In the explosion-proof protection device applied to the lithium battery test, as a further scheme, the first through holes play a role in heat dissipation, and the array arrangement is favorable for uniform heat dissipation.

Furthermore, at least one wiring hole is formed in at least one side face of the rectangular box body.

In the explosion-proof protection device applied to the lithium battery test, as a further scheme, the wiring hole is used for the test wire to pass through.

Further, the insulating layer is a bakelite plate.

In the explosion-proof protection device applied to the lithium battery test, as a further scheme, the bakelite plate has the effects of high temperature resistance and corrosion resistance.
