Description
Technical field
The utility model relates to battery system, particularly relates to a kind of battery system that is applied to electric automobile.
Background technology
Along with the development of electronic industry, battery system has been applied to multiple fields.Battery system generally comprises a Battery case and is arranged on a plurality of battery modules in Battery case.For the battery system being applied in electric automobile, in order to meet the requirement of electric automobile continual mileage, battery system, lithium-ion battery systems for example, its gross energy is more and more higher, and the energy density of single battery casing is also more and more higher.The energy density of lithium ion battery is higher, and the probability that blast on fire occurs is larger.In battery system, single battery in the battery modules in casing often on fire is first on fire, and then causes the combustion explosion of whole battery system.
Yet existing battery system initiatively reduces the possibility of battery combustion explosion when indoor design by the mode such as cooling, but battery explosion possibility on fire still can not be avoided completely.Once and combustion explosion occurs existing battery system, but there is no emergency treatment.Existing lithium-ion battery systems is in order to accomplish thermal insulating, high strength, waterproof and dustproof, shell body often adopts the metal materials such as high-intensity steel plate or aluminium alloy, and leave no room for manoeuvre edge insulation is processed to shell body, and the sealing property of casing will reach IP67 standard.If such measure has just caused battery system inside on fire, only from outside, put out a fire, do not reach fast the effectively object of fire extinguishing.The intensity of a fire such as often only have very large, just can play the effect of fire extinguishing after having burnt battery system housing, but now cause larger loss, and the intensity of a fire is also wayward, very likely burns whole electric motor car.
Utility model content
Technical problem to be solved in the utility model is: make up above-mentioned the deficiencies in the prior art, propose a kind of battery system, when there is burning, can fast and effeciently put out a fire, reduce the destructiveness of fire.
Technical problem of the present utility model is solved by following technical scheme:
A kind of battery system, comprise a Battery case and be arranged on a plurality of battery modules in described Battery case, at least one battery modules, be provided with Smoke Sensor, described battery system also comprises controller, extinguishing chemical storage tank and feed tube, offer a plurality of spray orifices on described feed tube; The output of described Smoke Sensor connects the input of described controller, the control signal output of described controller connects the valve on described extinguishing chemical storage tank, the spout of described extinguishing chemical storage tank is communicated with described feed tube, it is inner that described feed tube extends into described Battery case, is arranged between described a plurality of battery modules.
The beneficial effect that the utility model is compared with the prior art is:
Battery system of the present utility model, by Smoke Sensor is set in battery modules, and extinguishing chemical conveyance conduit is set between battery modules, when there is burning, after Smoke Sensor detects, by the control of controller, extinguishing chemical is delivered in battery modules from storage tank, directly to battery modules spraying fire-extinguishing agent, thereby single battery just can be put out a fire at the beginning of on fire in battery modules, fast and effeciently put out a fire, reduce the destructiveness of fire, reduce property loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of the battery system in the utility model embodiment.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further details.
As shown in Figure 1, be the structural representation of the battery system in this embodiment, battery system, for example lithium-ion battery systems, comprises Battery case 1, is arranged on a plurality of battery modules 2 in Battery case, Smoke Sensor 3, controller 7, extinguishing chemical storage tank 6 and feed tube 4.Wherein on feed tube, offer spray orifice 5, as the spray hole of extinguishing chemical.In at least one battery modules 2, be provided with Smoke Sensor 3, in this embodiment, in a Battery case, have 8 battery modules 2, preferably, in these 8 battery modules 2, be provided with Smoke Sensor 3.Smoke Sensor 3 can be ion type smog transducer.
Wherein, the output of Smoke Sensor 3 connects the input of controller 7, the control signal output of controller 7 connects the valve on extinguishing chemical storage tank 6, the spout of extinguishing chemical storage tank 6 is communicated with feed tube 4, feed tube 4 extends into Battery case 1 inside, is arranged between described a plurality of battery modules 2.
During work, once there have single battery to occur in battery modules 2 to be on fire, Smoke Sensor 3 detects Battery case 1 inside has smog to produce, the signal that gives the alarm, alarm signal transfers to the controller 7 of Battery case 1 outside, and controller 7 is opened the valve on extinguishing chemical storage tank 6, extinguishing chemical is exported from extinguishing chemical storage tank 6, by feed tube 4, be delivered to Battery case 1 inside, by the spray orifice 5 on feed tube 4, be sprayed onto in battery modules on fire 2, play the effect of quick extinguishing.
Preferably, the extinguishing chemical storing in extinguishing chemical storage tank 6 is liquid carbon dioxide.During liquid carbon dioxide ejection fire extinguishing, reduce ambient temperature, simultaneously starvation.This mode can not damaged remaining battery modules, does not have battery on fire to use after fire extinguishing.After avoiding water as extinguishing chemical, Battery case 1 to be put out a fire, can cause the short circuit of whole casing, and the reaction of brine electrolysis can occur, brine electrolysis produces hydrogen and oxygen, more dangerous after chance naked light.
Further preferably, the spray orifice on feed tube is arranged on the position that faces each battery modules.Like this, extinguishing chemical ejiction opening is directly aimed at battery modules, fire extinguishing better effects if, quicker.
In this embodiment, in battery system, set up Smoke Sensor, controller, extinguishing chemical storage tank and feed tube, detect burning phenomenon on fire by Smoke Sensor, and alarm signal is transferred to controller, by controller, control storage tank valve, make extinguishing chemical deliver to Battery case inside from feed tube output, directly to battery modules spraying fire-extinguishing agent, reach fast the effectively object of fire extinguishing.By timely fire extinguishing, battery modules not on fire is avoided being burned, thereby reduces the destructiveness of fire, reduces property loss.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, make without departing from the concept of the premise utility some substituting or obvious modification, and performance or purposes identical, all should be considered as belonging to protection range of the present utility model.
