Machine.
The temperature-time acquisition module 30 is used to be less than in the time difference of two adjacent sampling time points described initial
The temperature value of different time points is acquired when being worth the sampling time interval maximum value set by setup module 10, and when two adjacent
Between the temperature value of the temperature difference put when being more than the temperature interval minimum value set by the initial value setup module 10.In order to abundant
Illustrate the operation principle of the temperature-time acquisition module 30, now with certain LFP battery because work is heated to thermal runaway when T-t curves
For, referring to Fig. 2, it can be seen that the operating temperature of the battery is divided into two stages, in the first stage (stage 1), battery is rigid
Just start to be triggered, since inside battery does not generate violent chemical reaction also, the Wen Sheng of battery core will very slowly.At this moment it samples
Time interval should grow a bit as possible, but cannot be more than 1 second, otherwise will not meet《Electric motor coach safety specification》Rule
It is fixed.And in second stage (stage 2), when battery core is heated to because of work close to thermal runaway, temperature can steeply rise, at this moment
Should be shorter when the time interval of sampling, how to quantify the time interval, is exactly according to 10 institute of the initial value setup module
The temperature interval minimum value of setting, as long as when the temperature difference for acquiring two time points is more than the temperature interval minimum value, i.e.,
The temperature difference of two adjacent time points is acquired.So as to allow acquisition time difference to become a dynamic process, both
Efficiency be can guarantee may insure accuracy, to promote the performance of the anti-failure cutting system 100 of the battery.
The temperature difference that the temperature rise rate computing module 40 is used to be acquired according to the temperature-time acquisition module 30 with

Calculate corresponding temperature difference and time difference, and by the temperature difference and time difference respectively with temperature interval minimum value and sampling
Time interval maximum value is compared.The data calculating and comparing module 50 is electrically connected with sampling module 20, and described in reception
The sampling of sampling module 20 and the data of passback, and include the time carrying out asking poor calculating with temperature by the data of passback, then again
The time difference after difference and temperature difference will be asked to be compared with temperature interval minimum value and sampling time interval maximum value.Finally will
This relatively after result be transferred to the temperature-time acquisition module 30.
The battery cutout module 60 is used for when dT/dt is more than set temperature rise rate parameter M, described in output cut-out
The order of the output of battery, i.e., when temperature rise rate is more than institute art temperature rise rate parameter M, the battery cutout module 60 will export
Order, the controller cut off the output of the battery according to the order by the switch module, avoid total thermal runaway.While by
Voltage drop and the temperature value of any moment are also acquired in the data collecting instrument, therefore the battery cutout module 60 is also not only used
It is cut off when the temperature value of any moment acquired when the sampling module 20 is more than institute's initially set temperature reference parameters
The output of the battery, and also export cut-out when the voltage drop of any moment is more than the initially set Voltage Reference parameter of institute
The order of the output of the battery.
Compared with prior art, the anti-failure cutting system of battery of the invention is adopted by the initial value setting module 10
Egf block 20, temperature-time acquisition module 30, temperature rise rate computing module 40, battery cutout module 60 cooperate with each other,
