Full operating temperature is high, and the safe working temperature of ternary material is low.
It further illustrates, the first preset value of the present invention can be expressed as K1, and second preset value can be with table
It is shown as K2.When K2 selected as 0, for LiFePO4 battery core, the temperature of 52 memory storage of the second storage unit can be 250 °, pin
To NMC ternary lithium batteries, the temperature of 52 memory storage of the second storage unit can be 170 °.It it should be noted that can be according to reality
Border situation or operative scenario are adjusted, however it is not limited to which first preset value is K1 or the second preset value is K2.
Wherein, for battery pack 1：The battery pack 1 further includes thermal conductive metal plate, such as Fig. 3 in addition to including above-mentioned part
Shown, the thermal conductive metal plate connects with the super heat-conductive pipe and battery core.Super heat-conductive pipe and thermal conductive metal plate, which are formed, efficiently to be passed
The temperature equalization system of thermal energy is passed, for multiple battery cores, storage bodies to be made to keep same temperature, and when thermal runaway occurs in local battery core,
Thermal runaway liberated heat is disperseed rapidly, avoids local battery core temperature is excessively high from thermal runaway occur so as to cause adjacent battery core, draws
Play the domino effect of thermal runaway.
Preferably, the super heat-conductive pipe, battery core, thermal conductive metal plate are multiple；The battery core is attached to the heat superconducting
Guan Shang；The length of multiple thermal conductive metal plates is identical, and arranged in parallel successively；The battery core is attached to the super heat-conductive pipe
On.
As a preferred embodiment, as shown in figure 4, the super heat-conductive pipe includes the first heat conducting pipe, the second heat conduction

Such as water.
It should be noted that wherein, the temperature of the battery body stored in the first storage unit 51 can choose battery
Multiple preset positions on bag 1, the representative as 1 temperature value of battery pack.
Embodiment two：
1 thermal runaway control system of a kind of power battery pack provided in this embodiment, as shown in figure 5, except including embodiment
Outside control system described in one, the system also includes timing modules 6；The timing module is used to periodically touch the control
Module 3 makes the control module 3 receive the detection data in the inductive module 2, and carries out data comparison.That is, control
Molding group 3 receives the signal of timing module, and repeats to receive the signal of inductive module 2 within the timing module same intervals time
Collection compares the receive the 3rd detection data with the first detection data and the second detection data respectively.
It is more than the described first detection data in the described 3rd detection data and is not up to the first preset value, also, the described 3rd
In the case that detection data are not up to the second preset value more than the described second detection data, that is to say, that if all gone well,
3rd detection data cover is stored in the first storage unit 51, replaces the temperature value of present battery bag body；Afterwards, wait
At the time of next secondary control signal receives the transmission detection data of inductive module 2.
Wherein, the purpose that the present embodiment is set by the time is in order to which Analysis of Superconducting heat pipe is in last moment and lower a period of time
It is too fast whether quarter changes；The variation whether anomalous variation, if the temperature change of super heat-conductive pipe is too fast, be still present with tactile
The situation that hair module 4 is activated；Specifically, illustration is given：
Timing module sets last moment control module 3 receive inductive module 2 send the detection data moment and, under
It is time T (unit interval) that one moment, which controlled module 3 to receive the time interval at the detection data moment that inductive module 2 is sent,；Then
The data detected before time T are respectively that the first numerical value (temperature value of the battery core stored before), second value (store before
The temperature value of battery pack body) and third value (temperature value of the super heat-conductive pipe stored before)；After by stand-by period T
The data of detection are respectively the 4th numerical value (temperature value of currently stored battery core), the 5th numerical value (currently stored battery pack sheet
The temperature value of body) and the 6th numerical value (temperature value of currently stored super heat-conductive pipe)；
In last moment, the first numerical value, second value are compared with third value, in the difference of the first numerical value and third value
It is worth for the first difference, the difference of second value and third value is the second difference；Under current time, the 4th numerical value, the 5th numerical value
It is relatively drawn with the 6th numerical value, is the 3rd difference in the difference of the 4th numerical value and the 6th numerical value, the 5th numerical value and the 6th numerical value
Difference is the 4th difference；
Specifically, if the first difference is compared with the 3rd difference, more than the 3rd preset value；Alternatively, the second difference and the 4th poor
Value is compared, more than the 4th preset value in the case of, then start warning device 41；If the first difference is compared with the 3rd difference, it is more than
3rd preset value；Also, in the case that the second difference and the 4th difference are more than the 4th preset value, then start warning device 41 and prevent
Blasting device 42.
That is, power battery pack thermal runaway control system provided by the invention, as shown in fig. 6, temperature relatively after
Determine that the battery pack is out of control, being more than the numerical value of the described first detection data in the described 3rd detection data, to reach first default
And/or, the 3rd detection data are more than the feelings that the described second numerical value for detecting data reaches the second preset value in the case of value
Under condition, then illustrate that super large heat pipe temperature is excessively high, triggering module can be started.Further carry out point of super heat-conductive pipe rate temperature change
Analysis is compared, and is compared if analyzing last moment with current time, and super heat-conductive pipe temperature change is too fast, then similary to start alarm triggering
Device.
A kind of power battery pack thermal runaway control system provided by the invention, can be irreversible in power battery thermal runaway
In the case of, postpone the time that entire power battery pack enters thermal runaway, the pedestrian for motroist and surrounding provides time enough
Evade danger.Specifically, set-up of control system of the invention has alarm system, when thermal runaway omen occur and alarm, gives
Motroist and the pedestrian of surrounding strive for escaping the time；Anti- blasting device is provided with, before battery pack is completely into thermal runaway, as far as possible
The burning and explosion of battery pack are avoided, reduces property loss.
Also, there is the thermal balance system that super heat-conductive pipe is formed, entire battery pack normally makes in the battery pack of the present invention
Used time temperature change is slow, and only when thermal runaway occurs in battery core, the amount of heat that battery core is broken into can just make heat superconducting tube temperature
The quick variation of degree.It can detect that battery pack is lost with the presence or absence of heat by the temperature change of super heat-conductive pipe in unit of account time T
Control risk；That is quickly the heat in battery pack during single battery thermal runaway can be discharged rapidly, avoids adjacent electricity
Pond also enters thermal runaway state；Entire battery pack has further been delayed to enter the time of thermal runaway.
