Technical field
The present invention relates to technical field of new energy, particularly a kind of automobile power cell case.
Background technology
New-energy automobile refers to the vehicle of every other power except gasoline, diesel engine, comprises pure electric automobile, hybrid vehicle, fuel cell car, natural gas engine automobile and solar telephone etc.What current volume of production and marketing was large is pure electric automobile and hybrid vehicle, and in these two kinds of new-energy automobiles, lithium-ion-power cell is widely applied.Lithium ion battery major part in mobile phone, notebook computer and other small portable electronic device is that monomer uses, and its safety issue is not too outstanding.Power-type lithium ion battery capacity generally in dozens or even hundreds of ampere-hour, easily because short circuit, collide, the reason such as to overcharge the faults such as blast on fire occur.Prevent the security incident of electrokinetic cell, except from inside battery strengthening researchs such as battery material, structure, techniques, reduce unsafe factor in essence, consider that when battery system is integrated battery module inside arranges packing, battery module housings arranges reinforcement, car load carries out layout to the installation site of battery, the risk brought when reducing collision.
Although had the above multiple consideration for safety and Technical arrangements, electrokinetic cell probability on fire fundamentally can not be stopped.And electrokinetic cell on fire after, why security incident can occur, and is because the hot gas of burning can enter passenger compartment and directly endangers personal safety, and flame can ignite other combustibles of car body, causes property safety and then causes personal safety accident.So how to improve Battery case fail safe, reduce car load and just become problem demanding prompt solution with personal security damage.
Current most of battery case is according to the totally-enclosed design of water proof and dust proof grade IP67, although can effectively prevent inside battery from external contamination, when inside battery generation thermal runaway, the heat that cells burst gives out and toxic gas can not be got rid of in time.
Summary of the invention
The object of the invention is to provide a kind of automobile power cell case, and its structure is simple, can improve the security performance of automobile.
Based on the problems referred to above, technical scheme provided by the invention is:
Automobile power cell case, comprise Battery case, described Battery case inside is provided with the grid type support for stationary power battery, the top of electrokinetic cell is provided with temperature sensor, described temperature sensor is connected with automobile controller signal, inlet valve is provided with bottom described Battery case, described Battery case top is provided with the aiutage being communicated to the outer air of car, the bottom of described aiutage is provided with air outlet valve, described inlet valve and described air outlet valve are connected to valve pump, and described valve pump is electrically connected with described automobile controller.
Further, air accumulator is connected to described inlet valve by the road, and described pipeline is provided with electromagnetically operated valve, and described electromagnetically operated valve is electrically connected with described automobile controller.
Further, the top of described aiutage is provided with filter screen.
Compared with prior art, advantage of the present invention is:
Adopt technical scheme of the present invention, when temperature sensor detects that the temperature of electrokinetic cell exceedes preset temperature, automobile controller controls valve pump and opens inlet valve and air outlet valve, high-temperature gas in Battery case or toxic gas are discharged from air outlet valve, automobile power cell can be avoided on fire, improve the security performance of automobile.
