The collision detection device for the electric automobile power battery pack is simple in structure, strong in practicability and can effectively detect the deformation situation of the power battery pack.
Description
Technical field
The utility model belongs to the electric vehicle engineering field, relates to a kind of electric automobile power battery group collision detecting device.
Background technology
Electrokinetic cell is as the core component of electric automobile, its reliability is related to the quality of car load, when collision happens, easily cause the electrokinetic cell bag to damage, thereby cause high pressure electric leakage, the danger such as on fire, whether the electrokinetic cell bag collides and collision situation just becomes extremely important so detect.
The collision detection of existing electric vehicle is used the collision sensing signal of safety air sac controller usually, but this mode detects is the situation that vehicle is collided, and can not direct-detection electrokinetic cell bag be collided and the deformation situation that causes.
Summary of the invention
There are the problems referred to above in the utility model for existing technology, has proposed a kind of electric automobile power battery group collision detecting device, and this device can effectively detect the collision situation of power battery pack when collision happens.
The utility model is realized by following technical proposal: a kind of electric automobile power battery group collision detecting device, power battery pack comprises battery-pack exterior casing, it is characterized in that, this pick-up unit comprises the warning device that whether testing circuit of deformation, the control chip that is connected with testing circuit occurs and be connected with control chip for detection of battery-pack exterior casing.
In above-mentioned electric automobile power battery group collision detecting device, described testing circuit comprises that power supply, pull-up resistor and at least one wire detect conductor, power supply connects pull-up resistor, pull-up resistor connects control chip, between described pull-up resistor and control chip, detection node is set, described wire detects conductor one end and connects detection node, other end ground connection.When wire detects the conductor fracture, can cause the magnitude of voltage of detection node to change, thereby judge the collision situation of electric battery.
In above-mentioned electric automobile power battery group collision detecting device, described wire detects conductor and adopts brittle conductor material to make, and detects conductor in wire and is wrapped with insulating material.Wire detects conductor owing to adopting brittle conductor material to make, and easily ruptures when bumping; Detect conductor with the wrapped with insulation present situation and can avoid wire to detect conductor and battery-pack exterior casing conductor, thereby impact detects.
In above-mentioned electric automobile power battery group collision detecting device, described wire detects the conductor loops winding and puts and be close on the battery-pack exterior casing.When battery-pack exterior casing because of collision deformation occurs, because battery-pack exterior casing plasticity is higher, and that wire detects conductor fragility is high, can rupture first so wire detects conductor.
In above-mentioned electric automobile power battery group collision detecting device, described wire detects the conductor loops winding and puts and embed battery-pack exterior casing.When battery-pack exterior casing because of collision deformation occurs, because battery-pack exterior casing plasticity is higher, and that wire detects conductor fragility is high, can rupture first so wire detects conductor.
In above-mentioned electric automobile power battery group collision detecting device, described supply voltage is 12V or 5V.
Prior art is compared; this electric automobile power battery collision detecting device detects conductor by wire is set at battery-pack exterior casing; and detect the voltage that wire detects conductor one end detection node by testing circuit and judge that wire detects conductor and whether ruptures; thereby infer the collision situation of battery-pack exterior casing; give the alarm when serious when battery-pack exterior casing collides, reminding driver or car owner take measures to protect power battery pack.
Description of drawings
Fig. 1 is utility model example structure principle schematic.
Among the figure, 1, battery-pack exterior casing; 2, pull-up resistor R; 3, detection node; 4, wire detects conductor; 5, control chip; 6, warning device.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.
As shown in Figure 1, this electric automobile power battery group collision detecting device comprises by power supply, pull-up resistor R2 and wire and detects the testing circuit that conductor 4 forms, and the control chip 5 that is connected with testing circuit and controlled the warning device 6 of warning by control chip 5.Wire in the testing circuit detects conductor 4 and has one at least, adopts brittle conductor material (such as semiconductor, white cast iron etc.) to make, and is enclosed with insulating material in these wire detection conductor 4 outsides.According to actual conditions, wire detects conductor 4 around the positions such as top, middle part or bottom that arrange and be close to battery-pack exterior casing 1.As preferred version, can be with many (such as three, can cover respectively the upper, middle and lower) wire detects conductor 4 and embeds battery-pack exterior casings 1 to avoid detecting effect because friction causes the fracture impact, by being set, many wire detection conductors 4 can comprehensively judge collision situation, in case the principal vertical line shape detects the erroneous judgement that conductor 4 causes because of the accident fracture.
In testing circuit, power supply connects pull-up resistor R2, and pull-up resistor R2 connects control chip 5, between pull-up resistor R2 and the control chip 5 detection node 3 is set, and wire detects conductor 4 one ends and connects detection node 3, other end ground connection.When wire detects conductor 4 fracture, can cause the magnitude of voltage of detection node 3 to change, thereby judge the collision situation of electric battery.In this implementation column, supply voltage is 12V or 5V.
Testing process of the present utility model is as follows:
Under normal circumstances; the voltage at detection node 3 places remains on a stable value; but when electric battery bumps; and when deformation occurs in battery-pack exterior casing 1; because detecting conductor 4, wire is close to (perhaps embedding) battery-pack exterior casing 1; the toughness of battery-pack exterior casing 1 is higher than the wire of being made by brittle conductor material and detects conductor 4; so detecting conductor 4, wire can rupture; so that the voltage of detection node 3 raises; control chip 5 detects change in voltage; thereby output order control warning device 6 alarms make driver or car owner in time take safeguard measure that electric battery is protected.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used battery-pack exterior casing 1, pull-up resistor R2, detection node 3, wire to detect the terms such as conductor 4, control chip 5, warning device 6, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
