Along with a large amount of uses of lithium ion battery, corresponding lithium battery management system have also been obtained the attention of research.People wish by the research to battery management system, and the overall performance of lithium battery and lithium battery group can be made to obtain maximum performance and maintenance.Relative to the price of lithium battery itself, the cost of battery management system is just much more.From another aspect, the existence of battery management system, is also the use optimizing this resource of lithium battery, reduces the waste of energy, also reduce the pollution of environment.The principal element affecting lithium battery performance and life-span comprises battery temperature, the internal resistance of cell, cell consistency etc., battery cell is owing to manufacturing and the otherness of environment for use, in the use procedure of battery, the otherness of battery cell will progressively worsen, the inconsistency of lithium battery monomer not only affects performance and the life-span of battery, and affect the safety of battery, lithium battery system always has the battery that monomer voltage is high, in relative group, other batteries enter overcharge condition earlier, the service life reduction of lithium battery can be made, even may there is inside battery substance combustion, this is definitely unallowed to underground coal mine.Meanwhile, most of survival capsules in the market, effectively can not manage lithium battery, and the energy that lithium battery stores can not be utilized effectively, and can not provide effective power supply to mine escape capsule.Therefore mine escape capsule lithium battery management system carries out efficiently managing being absolutely necessary to lithium battery.
Utility model content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of mine escape capsule lithium battery management system in useful life improving lithium battery reliability and security of system, prolongation lithium battery.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of mine escape capsule lithium battery management system, comprise power supply, rectification circuit, charge control module, dsp processor, lithium battery group, human-computer interface module, detection module, rectification circuit input end is connected with power supply, dsp processor is connected with human-computer interface module, charge control module, lithium battery group respectively, dsp processor carries out charge and discharge control to lithium battery group and realizes the equilibrium of lithium battery group, and dsp processor is controlled charge control module by PWM ripple.
Human-computer interface module comprises parameter setting module and display module, and man-machine interface adopts TFT display screen.
Detection module comprises voltage detecting, current detecting, temperature detection.
When in case of emergency will use survival capsule, lithium battery group for subsequent use is exactly an independently power supply, to survival capsule energy supply.When lithium battery work, the surface temperature of the voltage of the total voltage to battery pack, cell, the operating current of battery pack and battery pack is needed to detect, monomer battery voltage difference comparatively large (exceeding set point), by dsp processor, charge and discharge control is carried out to lithium battery group and realize the equilibrium of lithium battery group, put to prevent the mistake of cell or overcharge, ensure the operation safely and efficiently of battery pack, and the information such as the voltage of these battery pack, electric current, temperature and dump energy are shown by display module, be convenient to observation operation.
Lithium battery group realizes communicating to connect by RS485 and control module, and dsp processor comprises communication unit, memory cell.
The beneficial effects of the utility model: the utility model uses mine escape capsule lithium battery management system, lithium battery in survival capsule is effectively managed, in solution lithium battery group, in each cell, portfolio effect is not good, extend the useful life of lithium battery, improve the discharge and recharge degree of depth of lithium battery group utilance and lithium battery group, ensure lithium battery group functional reliability and security of system.
Accompanying drawing illustrates:
Fig. 1 is theory diagram of the present utility model.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of mine escape capsule lithium battery management system, comprise power supply, rectification circuit, charge control module, dsp processor, lithium battery group, human-computer interface module, detection module, rectification circuit input end is connected with power supply, dsp processor is connected with human-computer interface module, charge control module, lithium battery group respectively, dsp processor carries out charge and discharge control to lithium battery group and realizes the equilibrium of lithium battery group, and dsp processor is controlled charge control module by PWM ripple.Human-computer interface module comprises parameter setting module and display module, and man-machine interface adopts TFT display screen.Dsp processor comprises voltage detecting, current detecting, temperature detection, and realize communicating to connect by RS485 and control module, dsp processor comprises communication unit, memory cell.
Lithium battery group is connected with electrical network as a load, when charging, power supply is through over commutation, by charge control module, lithium battery group is charged, detection module detects lithium battery group voltage, electric current, temperature, the signal detected, after A/D conversion, enters data in dsp processor, and simultaneously dsp processor carries out charge and discharge control to lithium battery group and realizes the balanced management of lithium battery group.Owing to inevitably there is inconsistency between each cell in lithium battery group, through dsp processor, charge and discharge control is carried out to lithium battery group and realize the equilibrium of lithium battery group cell, the overall performance of battery pack can be improved to a great extent.Because do not carry out balanced management to lithium battery group, time cell in lithium battery group is full of electricity, battery management system will control to cut off the charging circuit to lithium battery group by charging, in single cell in lithium battery group is discharged, battery management system will by the discharge circuit of control of discharge cut-out to battery pack, and other cells there will be the situation not being full of electricity or being discharged, cause lithium battery group overall utilization rate not high.In the utility model mine escape capsule lithium battery management system, detection module detects monomer battery voltage, temperature, electric current, the energy of each cell is judged by dsp processor, namely that cell will absorb energy, that cell needs to release energy, by equal charge and discharge control, energy is shifted between lithium battery group, therefore, dsp processor carries out charge and discharge control to lithium battery group and contributes to controlling the discharge and recharge degree of depth of battery pack.In work, dsp processor is controlled charge control module by PWM ripple, communication unit adopts RS485 communication interface, use Modbus as communication protocol, the correctness of transfer of data is ensured by CRC check, also facilitate other to use the equipment interface networking of same protocol simultaneously, thus ensure that equipment room passes data effectively mutually, make system compatibility good, memory cell stores the data in control module, realize communicating to connect by RS485 and control module, according to the data that detection module detects, charge and discharge control is carried out to single lithium battery.
