Substantially regard purposes of discussion, rather than to limit the present invention.
The embodiment of the invention discloses a kind of fire-retarding devices, are suitable for power battery pack 101, which includes: single
To exhaust valve 102, it is arranged in the power battery pack 101；Air accumulator 103 is arranged in the power battery pack 101,
Inside it is stored with fire-retardant gas；Detector (not shown), for detecting the pressure value in power battery pack 101.
In embodiments of the present invention, as an implementation, the fire-retardant gas is inert gas.
In conjunction with above-mentioned fire-retarding device, the embodiment of the invention also discloses a kind of flame resistant methods comprising the steps of:
S201, the air in power battery pack is discharged；
S202, when the pressure for detecting power battery pack reaches preset value, fire-retardant gas is filled with into power battery pack.
If the single battery of S203, power battery pack breaks down, the gas in power battery pack is discharged.
The accounting of fire-retardant gas in S204, detection power battery pack, if lower than default accounting value, into power battery pack
Inject fire-retardant gas.
The embodiment of the invention also discloses a kind of electric cars, include a power battery pack, the power battery, which is wrapped, to be set
It is equipped with above-mentioned fire-retarding device.
In embodiments of the present invention, as an implementation, electric car includes a controller, the controller control
One-way exhaust valve and air accumulator processed open or close.
In embodiments of the present invention, as an implementation, electric car includes a human-computer interaction device, when the storage
