After corresponding balance module 21 is activated, the balance module 21 works, and it is equal to carry out voltage to corresponding single battery core 0
Weighing apparatus, and heat can also improve the temperature of battery modules caused by its work；Meanwhile radiating module 23 is also started up, this dissipates
Thermal modules 23 are started working, to radiating for battery modules.Furthermore, it is desirable to explanation, now, the work production of balance module 21
Raw heat, radiated also by radiating module 23.
The third working method, when checking the voltage of single battery core 0 in the range of given voltage and temperature is less than specifying
During temperature range, i.e., when inspection result is low temperature and consistent voltage, now, it is only necessary to the temperature of battery modules is improved, without
Electric voltage equalization processing is carried out to single battery core 0, therefore, step S302 includes：Specified control is sent to temperature management system 2 to refer to
Order, it is at least one to battery mould in balance module 21 in temperature management system 2, heating module 22 and radiating module 23 to cause
Group, which carries out equilibrium treatment, to be included：The 3rd control instruction is sent to temperature management system 2, to close each balance module 21 and institute
Radiating module 23 is stated, starts the heating module 22.
4th kind of working method, when checking the voltage of single battery core 0 in the range of given voltage and temperature is higher than specifying
During temperature range, i.e., when inspection result is high temperature and consistent voltage, now, it is only necessary to the temperature of battery modules is reduced, without
Electric voltage equalization processing is carried out to single battery core 0, therefore, step S302 includes：Specified control is sent to temperature management system 2 to refer to
Order, it is at least one to battery mould in balance module 21 in temperature management system 2, heating module 22 and radiating module 23 to cause
Group, which carries out equilibrium treatment, to be included：The 4th control instruction is sent to temperature management system 2, to close each balance module 21 and described
Heating module 22, start the radiating module 23.
5th kind of working method, when checking the voltage of single battery core 0 not in the range of given voltage and temperature is being specified
During temperature range, i.e., inspection result is when being adapted to temperature and inconsistent voltage, now, it is only necessary to carries out voltage to single battery core 0
Equilibrium treatment, without entering trip temperature adjustment, therefore, step S302 includes：Specified control is sent to temperature management system 2 to refer to
Order, to cause balance module 21, heating module 22 and radiating module 23 in temperature management system 2 to include：To temperature treatment system
System 2 sends the 5th control instruction, to start corresponding balance module 21, closes the heating module 22 and the radiating module
23。
6th kind of working method, when checking the voltage of single battery core 0 in the range of given voltage and temperature is specifying temperature
When spending scope, i.e., inspection result is when being adapted to temperature and consistent voltage, now, it is not necessary to carry out electric voltage equalization and the tune of temperature
Whole, balance module 21, heating module 22 and radiating module 23 do not work.
Specifically, the control mode of startup and the closing of balance module 21 can be, when the corresponding balance module 21 of startup
When, switching tube 211 of the battery core management system 1 by the first output port out1 into corresponding balance module 21
Switch control terminal exports the first signal, controls the switching tube 211 to close, to cause corresponding connected single battery core 0
Between turn on, with to the battery modules carry out electric voltage equalization processing；
When closing each balance module 21, battery core management system 1 by the first output port out1 to it is each
The switch control terminal output secondary signal of switching tube 211 in the module 21 that weighs, controls the switching tube 211 to end, to cause pair
End between the connected single battery core 0 of equalizing resistance 212 answered, electric voltage equalization processing is not carried out to the battery modules.
It should be noted that startup and the realization of closing heating module 22 or radiating module 23 can also be by setting respectively
Switching tube is put, by controlling the conducting and cut-off of respective switch pipe, so as to realize to heating module 22 or radiating module 23
