Description
Technical field
The utility model relates to the battery pack technical fields of electric vehicle, more particularly to one kind to have fire behavior early warning and prevention and control
The battery pack of function.
Background technique
With the propulsion of energy-saving and environment-friendly main trend, electric car increasingly becomes the first choice that country advocates, power battery
It is one of the component for constituting electric car most critical.Either hybrid electric vehicle or pure electric vehicle all rely on mature move
Power battery technology.In recent years, with the development of electric car, domestic independent brand Automobile Enterprises are laid out the production of new energy upstream one after another
Industry chain, autonomous or commission external supplier are accelerating the research and development and production of power battery.
Currently, due in power battery pack work because the moment increase of contact discharge current, line short, battery core short circuit etc. can
The temperature such as internal wiring, electronic component can be caused to increase and then burn, this proposes the fire extinguishing control function of power battery pack
It is required that.Current batteries of electric automobile packet BMS is equipped with early warning protection system, but the system of fire behavior early warning and control is seldom, state
Internal and external parts new-energy automobile, because lacking fire behavior early warning and control measure, can not prevent fire behavior from disliking after fire behavior occurs for battery pack
Change and huge accident occurs.
Utility model content
In battery core heat occurs for the battery pack with fire behavior early warning and prevention and control function that the purpose of the utility model is to provide a kind of
When out of control, fire behavior prewarning controller can rapid early warning, and effectively start extinguishing device controls fire behavior to a certain extent,
Escape time is increased to passenger, increases the safety that electric car uses.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of have the function of fire behavior early warning and prevention and control
Battery pack, including battery pack ontology is vertically equipped with partition among the battery pack ontology, and the partition is equipped with switch, institute
It states and switchs lower section equipped with control device, the control device lower section is equipped with gas-detecting device, the gas-detecting device lower section
Equipped with miniature fire extinguisher；The partition two sides are equipped with battery case, and card is placed with battery module, the battery mould in the battery case
Thermocouple is equipped between block and control device.
Further, the switch includes that miniature fire-extinguisher cock and gas-detecting device switch.
Further, the control device includes controller, alarm device, and alarm device is electrically connected with the controller, described
Controller is electrically connected with gas-detecting device, thermocouple, miniature fire extinguisher.
The beneficial effects of the utility model are: the device is when thermal runaway occurs for single battery core, gas-detecting device can be examined
Measure the peculiar gas that abnormal battery core generates, while thermocouple detects temperature anomaly, to generate early warning, triggering fire extinguisher into
Row fire extinguishing guarantees can there is emergency measure after thermal runaway occurs in battery pack, while to occupant's offer warning information and effectively
Escape time increases the safety that electric car uses, in addition not will increase battery pack using the miniature fire extinguisher of automatic control
Space, structure whole design is reasonable, be suitable for large-scale promotion use.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the battery pack with fire behavior early warning and prevention and control function of the utility model.
In figure: 1, battery pack ontology, 2, battery case, 3, battery module, 4, thermocouple, 5, switch, 6, control device,
7, gas-detecting device, 8, miniature fire extinguisher, 9, partition.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
A kind of battery pack with fire behavior early warning and prevention and control function, including battery pack ontology 1, in the battery pack ontology 1
Between be vertically equipped with partition 9, the partition 9 is equipped with switch 5, equipped with control device 6, the control device 6 below the switch 5
Lower section is equipped with gas-detecting device 7, is equipped with miniature fire extinguisher 8 below the gas-detecting device 7；9 two sides of partition are all provided with
There is battery case 2, card is placed with battery module 3 in the battery case 2, and thermocouple is equipped between the battery module 3 and control device 6
4。
Further, the switch 5 includes that miniature fire-extinguisher cock and gas-detecting device switch.
Further, the control device 6 includes controller, alarm device, and alarm device is electrically connected with the controller, described
Controller is electrically connected with gas-detecting device 7, thermocouple 4, miniature fire extinguisher 8.
Specific embodiment occurs fire behavior inside battery pack or temperature anomaly is excessively high, and heat occurs inside battery pack and loses
When control, gas-detecting device 7 detects the peculiar gas generated in abnormal battery pack, while thermocouple 4 detects that temperature is different
Often, the information that will test jointly passes to controller, and controller starts alarm device, while triggering miniature fire extinguisher 8 and carrying out
Fire extinguishing guarantees can there is emergency measure after thermal runaway occurs in battery pack, while providing warning information to occupant and effectively escaping
The raw time.
Wherein, using miniature fire extinguisher 8 and controller, while reaching self-extinguishing, excessive space, structure are not take up
Design is reasonable.
In the description of utility model, it is to be understood that term "front", "rear", "left", "right", "upper", "lower" etc. refer to
The orientation or positional relationship shown be based on the orientation or positional relationship shown in the drawings, be merely for convenience of description the utility model and
Simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation and specific orientation structure
It makes and operates, therefore should not be understood as the limitation to utility model.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent character made based on the specification and figures of the utility model or Structural Transformation, are applied directly or indirectly in other
Relevant technical field, is also included in the patent protection scope of the utility model.
