After battery compartment 21 is connected with the battery 1 for needing to be charged, battery 1 is triggered, battery 1 is according to computer-controlled program
The mark of battery 1 and discharge curve are sent to charging cabinet 2 by the connecting interface of battery compartment 21.Charging cabinet 2 passes through controller
23 receive the mark and discharge curve of battery 1, and are temporarily stored in memory 22.
S303, mark and discharge curve to server transmission battery.
Controller 23 in charging cabinet 2 sends the mark of the battery 1 of interim storage in memory 22 and discharge curve
To server 3.The mark and charging curve of the storage battery 1 of server 3.
S304, charging cabinet record the mark and charging curve of battery in charging process.
After battery compartment 21 is connected with the battery 1 for needing to be charged, battery 1 is charged.In the charging process of battery 1,
Charging cabinet 2 records the mark and charging curve of battery 1 by battery compartment 21.
S305, charging cabinet send the mark and charging curve of battery to the server after the charging terminates.
After the battery 1 is fully charged in charging cabinet 2, charging cabinet 2 completes the charging curve of record battery 1.Charging cabinet 2
The mark of battery 1 and charging curve are sent to by server 3 according to the control command of controller 23.The storage battery 1 of server 3
Mark and charging curve.By recording the discharge curve and charging curve of battery 1, the whole service week of battery 1 can be obtained
The discharge and recharge data of phase, the performance of battery can be analyzed as big data.
S306, judge whether discharge curve meets pre-provisioning request.
The program that server 3 is set by inside judges whether discharge curve meets predetermined requirement.If met, hold
Row S307 steps.In an optional embodiment, server 3 can also be by judging whether charging curve meets predetermined want
Ask and then perform S307 steps.The pre-provisioning request can accurately react discharge process or whether charging process is normal.
S307, battery cycle-index increase once.
When the discharge curve for the battery 1 that server 3 receives meets predetermined requirement, the cycle-index increase by one of battery 1
It is secondary, and be stored in server 3.
Whether S308, charging cabinet detection battery maximum electricity decay reach drop threshold.
After battery 1 is fully charged, whether the maximum electricity decay that charging cabinet 2 detects battery 1 reaches drop threshold.It is described to decline
Subtract threshold value can be it is being manually set with battery specified electric quantity into certain ratio, can also be determined according to substantial amounts of experiment
Drop threshold.When the maximum electricity decay of battery 1 reaches drop threshold, S309 steps are performed.When the maximum electricity of battery 1 declines
When subtracting not up to drop threshold, S310 steps are performed.Preferably, declining for the maximum electricity of battery 1 is detected by charging cabinet 2
Subtract, can highly precisely ensure that attenuation degree of the battery when reaching retired is essentially identical, ensure the validity of cascade utilization.
S309, battery is forbidden to be continuing with, the mark and disabling notice in concurrent power transmission pond.
When the maximum electricity decay of the battery 1 of detection reaches drop threshold, the battery compartment where corresponding battery 1 is controlled
21 close, and forbid battery to continue as user's use.The mark of battery 1 and disabling notice are sent to server 3 simultaneously.Server
3 can control the battery compartment 21 to close according to the mark and disabling notice of battery 1, no longer provide the user replacing service.Dimension
The disabling notice and the mark of battery 1 that shield personnel receive according to server 3, timely take the disabling battery in charging cabinet 2 away.
S310, battery is allowed to be continuing with.
When the maximum electricity decay of the battery 1 of detection is not up to drop threshold, the battery where corresponding battery 1 is controlled
Storehouse 21, when receiving the request of user's replacing battery, opening provides the user battery.
Whether S311, the cycle-index of server detection battery reach quality guarantee threshold value.
Server notifies according to the battery mark and disabling that receive, obtains following for battery corresponding to the battery identification
Ring number.The cycle-index of the battery 1 is detected, whether the cycle-index for detecting the battery 1 reaches quality guarantee threshold value.
The cycle-index of the battery 1 reaches quality guarantee threshold value, performs S312 steps.The cycle-index of the battery 1 is not up to quality guarantee threshold
Value, perform S313 steps.The quality guarantee threshold value is counted to calculate according to the maximum cycle of all batteries of record and obtained, can be with
It is the average cycle index of battery or the * n% of average cycle index obtained.In one alternatively embodiment, quality guarantee threshold value
It can also be default cycle-index.
S312, the battery set retired mark.
When the cycle-index of the battery 1 reaches quality guarantee threshold value, retired mark is set for the battery.Attendant's root
According to the retired mark of the battery of acquisition, the battery is taken away, carries out the utilization of next step.Retired battery is still latent
The huge surplus value is hidden, its capacity and power still can meet the needs of a variety of energy storage occasions, such as electric power system, communication base
Stand, data center, the application such as wind light generation energy storage.Capacity and residual life detection are carried out for lossless unpack, is tied by detecting
Fruit is screened, matched, in groups or into system, carries out secondary use, plays the surplus value.For the electricity being worth without energy storage
Pond, carry out housing and disassemble, raw material refine.
S313, the battery set quality guarantee to mark.
When the cycle-index of the battery 1 is not up to quality guarantee threshold value, quality guarantee is set to mark for the battery.Attendant
Marked according to the quality guarantee of the battery of acquisition, after the battery is taken away, quality guarantee processing is carried out to the battery.Cycle-index
It is important Judging index, is the foundation with battery producer quality guarantee.Cycle-index is that time of qualified capacity whether can be released with battery
Based on number is reached.The capacity of the battery of required quality guarantee does not reach requirement still after maintenance, battery is forced retired
Into cascade utilization downstream.
In the present embodiment, battery management system by charging cabinet 2 and server 3 for the battery 1 in all operations
Data be managed, so as to obtain the use data of all batteries exactly, electricity for being aged to predetermined extent
