Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
Fig. 1 is the flow chart of the electrokinetic cell recovery method in an embodiment.This electrokinetic cell recovery method is used for
The electrokinetic cell eliminating electrical equipment especially electric automobile reclaims.In the present embodiment, power current
Pond is the battery bag including multiple battery modules, and each battery modules includes multiple cell.Multiple
Battery modules can connect in the way of using in parallel or in series, and can also use between multiple cell
Mode in parallel or in series connects formation battery modules.Specifically, this electrokinetic cell recovery method include with
Lower step:
S102, reads the state parameter information of battery bag.
The state parameter information of battery bag is read by battery management system BMS.The state parameter letter of battery bag
Breath includes discharge and recharge data, voltage, electric current, temperature and capacity etc..In one embodiment, S102 it
Before, also can first judge this battery bag whether can continue on electrical equipment and use (namely the need of eliminating),
And only cannot continue to use on electrical equipment at battery bag and just it can be recycled.Specifically,
BMS reads and records the operation information of battery bag, and judges whether to need to be eliminated according to operation information.
Operation information can include the discharge and recharge data of electrokinetic cell, voltage, electric current, internal resistance, temperature and capacity
Deng.When BMS judges to need to eliminate electrokinetic cell, system can send the information changing battery bag.
Such as, when the off-capacity of electrokinetic cell is to meet required mileage number, this electrokinetic cell can be assert
Needs are replaced.
The battery bag eliminated on power-equipment is dismantled, and is read the state ginseng of battery bag by bus
Number information.The state parameter information read includes the historical record of battery bag and current state parameter.
According to the state parameter information of battery bag, S104, judges that battery bag is the most faulty.
The situation of the state parameter information according to battery bag can judge whether battery bag exists fault.Judge
Process can use determination methods commonly used in the art to complete.Such as, when the discharge and recharge data exception of battery bag
Time, it can be determined that this battery bag cannot be carried out normal discharge and recharge, so that it is determined that this battery bag exists fault.
It is of course also possible to be compared to whether judge this battery bag with the normal range preset by other state parameters
There is fault.When judging that this battery is surrounded by fault and then performs S104, otherwise perform S116.
S106, detects the battery modules in out of order battery bag.
Battery bag is disassembled, obtains multiple battery modules.By charge and discharge device to the electricity in battery bag
Pond module carries out charge-discharge test, to test electric current, voltage, module internal resistance and charge/discharge capacity etc..
S108, it is judged that each battery modules is the most faulty.
Battery is the most normally judged according to the electric current detected, voltage, module internal resistance and charge/discharge capacity
Module is the most faulty.If faulty, perform S110, otherwise perform S118.
S110, detects the cell in out of order battery modules.
Battery modules is disassembled, to obtain multiple battery cell.By charge and discharge device to cell
Discharge and recharge data, electric current, voltage, internal resistance and capacity etc. detect.
S112, it is judged that each cell is the most faulty.
Judge that each cell is the most faulty according to testing result, if it is perform S114, otherwise perform
S120。
S114, disassembles out of order cell and reclaims the metal in cell.
Cell is disassembled thus the valuable metals such as copper therein, cobalt and nickel are reclaimed, and right
Obsolete material is classified automatically.
S116, recycles not having out of order battery bag.
Do not have out of order battery bag can to fill out realizing peak clipping as the energy storage device of the first energy storage for power supply equipment
Paddy function.First energy storage for power supply equipment can be the equipment that the energy storage capacity such as large-scale energy-accumulating power station are bigger.
S118, recycles not having out of order battery modules.
Can will not have the out of order battery modules energy storage device as the second energy storage for power supply equipment.Wherein,
The energy storage capacity of two energy storage for power supply equipment is less than the energy storage capacity of the first energy storage for power supply equipment.Second energy storage for power supply
Equipment can be UPS (uninterruptible power system), low profile photovoltaic accumulation power supply and portable accumulation power supply
Deng small-sized energy storage device.It is appreciated that do not have out of order battery bag and the battery modules all can be at other
As storage device in the energy storage device of capacity matching.
S120, recycles not having out of order cell.
To not having out of order each cell to classify, thus of a sort cell is carried out combo with
Recycle.Specifically, can classify according to the voltage of cell, internal resistance and capacity, will
It is stand-by that the close battery of performance carries out combo as same class.The combo of cell include capacity combo,
The methods such as the combo of battery standing voltage combo (terminal voltage combo) and battery charging state dynamic electric voltage.At it
Embodiment in, cell can also individually recycle.
Above-mentioned electrokinetic cell recovery method, by reading the state parameter of the battery bag that electrical equipment is eliminated
Take thus judge that this battery bag is the most faulty, and to not having out of order battery bag to recycle.Enter one
Step, also can detect to judge whether each battery modules has to the battery modules in out of order battery bag
Fault, and to not having out of order battery modules to recycle, to the monomer in out of order battery modules
Battery carries out detecting out of order cell not had to recycle, by out of order cell then
Carry out disassembling and valuable metal being recycled, thus realize the cascade utilization of electrokinetic cell.Relative to
Traditional direct the electrokinetic cell that electrical equipment is eliminated is carried out the processing method disassembled for, above-mentioned power current
Pond recovery method greatly improves the utilization ratio of electrokinetic cell, and resource utilization is higher.Reality at other
Execute in example, it is also possible to only battery bag and battery modules are reclaimed, and direct to out of order battery modules
Demolishing and scrapping.
Fig. 2 is the structural representation of the electrokinetic cell recovery system in an embodiment, and this electrokinetic cell reclaims system
System recycles for the electrokinetic cell eliminating electrical equipment.This electrokinetic cell recovery system includes electricity
