Description
Technical field
The utility model is related to fire alarm field, especially a kind of temperature-sensitive, sense cigarette, photosensitive combination type fire detector.
Background technology
Electric vehicle is individually or simultaneously to use automobile of the accumulator as stored energy power source, it is using accumulator as storage
Motility source provides electric energy, drive motor operating, to push running car by battery to motor.With world's energy
Source shortage and environmental pollution situation it is increasingly serious, electric vehicle increasingly attracts attention and favors, with respect to orthodox car
Speech, effect on environment is small, has a extensive future.
As the power source of electric vehicle, although the use environmental pollution of battery is small and reusable, its
There is some potential safety problemss, in the case where meeting certain condition, there are short circuit, the danger such as catch fire, huge due to gathering in battery
Big energy such as carries out fire extinguishing control not in time when battery burns, and may lead to the danger exploded, directly close
The personal safety of driver and passenger, while will also result in larger property loss.
Battery for electric vehicle is generally positioned in battery case, and battery case is mounted on automobile, and battery is narrow
It charged, discharged or in use, anode in battery and cathode have the danger that short circuit occurs in battery case spatial dimension, with
For lithium battery, after short-circuit heat, which occurs, for battery gathers, the electrolyte temperature in battery is higher（More than 40 °）When, lithium battery
Thin polymer film between anode and cathode will be slowly breakdown, so as to cause more positive and negative anodes short circuits in battery, in turn
More heats are discharged, gathering for energy is further development of cells burst or explosion.Battery from be shorted to explode it is whole
During a, there are multiple key nodes：
1, battery is short-circuit in the early stage, and there are the fire signals such as corona, electric arc or electric spark in battery case at this time；
2, thin polymer film fusing breakdown, due to battery short circuit, can discharge certain heat, cause thin polymer film molten
Change, breakdown, there are certain smog in battery case at this time；
3, the temperature rise in battery case, since the space in battery case is limited, after thin polymer film is breakdown, battery
Sustained release heat causes the temperature in battery case soaring.
It is objective reality that the fact of short circuit is concentrated and occurred to the energy of battery, as long as using battery inevitably
In face of it is on fire, explosion the problem of, and how effectively fire occur starting stage detect battery dangerous situation in time, to have
Effect takes the measures such as cooling, fire extinguishing, just becomes the important channel for ensureing personal safety and safety of property, the battery dangerous situation packet of starting stage
It includes battery and the nodes such as short circuit, thin polymer film breakdown, temperature rise occurs.Traditional battery case fire extinguisher uses separate layout
Hand fire extinguisher or transportable fire extinguisher, the fire extinguisher of this separate layout relies primarily on manual operation, when artificial hair
Existing battery ignition when, just proceed by fire-extinguishing operations, this fire dangerous situation finds later, has explode at any time
Danger, in this case driver and passenger cannot withdraw in time, explosion may occur when fire extinguishing at any time and also directly threaten fire extinguishing
The personal safety of personnel, so, the case where battery temperature being arranged in battery case is increased or will be burnt how is found as early as possible,
As the maximally efficient approach of control cells burst or explosion.
Utility model content
The goal of the invention of the utility model is：It is sent out for that cannot be detected in battery case in time in the presence of the prior art
