As shown in fig. 1, an embodiment of the present invention provides a battery safety box for storing a battery 70, the battery safety box including: a case 10, the case 10 having a receiving cavity for receiving a battery 70; and the heat absorbent 20 is arranged in the accommodating cavity, and the heat absorbent 20 can absorb heat to generate gas.
By applying the technical scheme of the embodiment, the heat absorbent 20 is arranged in the box body 10 of the battery safety box, so that a large amount of heat generated by the battery can be absorbed by the heat absorbent 20 when the battery 70 is out of control due to heat, the heat absorbent 20 can be gasified after absorbing heat, the gasified heat absorbent 20 can be discharged to the outside, and high-temperature gas generated by the battery can be discharged together, so that the heat and pressure in the battery safety box are greatly reduced, and the danger of explosion and the like of the battery is avoided.
In the present embodiment, the heat absorbent 20 is disposed on the inner wall of the receiving chamber, which facilitates the heat absorbent 20 to absorb heat when thermal runaway of the battery 70 occurs.
In this embodiment, the battery safety box further includes: and a carrier disposed on an inner wall of the receiving chamber, the carrier having a plurality of voids therein, the endothermic agent 20 being filled in the voids. The attachment and distribution of the heat sink 20 is facilitated by the provision of the carrier.
In the present embodiment, the endothermic agent 20 is a vaporization type endothermic agent or a decomposition type endothermic agent. Thus, the heat absorbent 20 generates gas after absorbing heat, and can take away and discharge a large amount of heat generated by the battery to the outside of the battery safety box. For example, the endothermic agent 20 may be water.
In this embodiment, the battery safety box further includes: and a package 41 disposed in the receiving cavity, the heat absorbent 20 being disposed in the cavity of the package 41, the package 41 being a sealed structure, the package 41 being capable of rupturing under a predetermined pressure or a predetermined temperature. Thus, when the battery is in thermal runaway, the packaging body 41 can be automatically opened, and then the heat absorbing agent absorbs and discharges heat in time. The wrapper 41 may be provided in a bag-like configuration.
In this embodiment, the packing 41 is plural, and the plural packing 41 are disposed at different positions of the inner wall of the receiving chamber, so that the heat absorbing effect to the battery 70 can be improved.
As shown in fig. 1, the battery safety box further includes: a first cap 30, which is arranged on the packaging 41, the first cap 30 being capable of opening at a predetermined pressure and/or at a predetermined temperature. Through the above arrangement, when the battery is normally charged, the first blocking cover 30 can play a sealing role, when the battery is out of thermal runaway, the temperature and the pressure in the battery safety box rise, the first blocking cover 30 can be automatically opened after a certain condition is reached, the gasified heat absorbent 20 can be timely discharged, and therefore a large amount of heat generated by the battery can be taken away. The first cap 30 may be provided in a plurality, with a plurality of first caps 30 being distributed at different locations of the package 41.
As shown in fig. 1, the battery safety box further includes: and the heat insulation layer 50 is arranged on the outer side of the box body 10 or the side of the heat absorbing agent 20, which faces away from the accommodating cavity.
