Abstract
The invention discloses a repair method for multiple parallel lithium ion battery modules. The method comprises the steps of 1) tracing initial assembling information and use information of the modules; 2) sorting the modules with a repair value according to requirements; 3) disassembling the modules into unit batteries; 4) inspecting the appearance, the capacity, the voltage, the internal resistance and the self-discharge rate of the unit batteries and screening out unacceptable batteries; 5) using acceptable batteries with the same model to replace the screened-out unacceptable batteries, and reassembling the batteries into modules according to the original module assembling method. The repair method for the multiple parallel lithium ion battery modules has the advantages that the situation of fully using new batteries for reassembling is avoided, the acceptable batteries in the original modules are reserved, the replacement process of battery modules is greatly simplified, the consistency of the module of the entire vehicle is improved and the battery use cost is reduced.
Description
Technical field
The present invention relates to the recovery technique field of lithium ion battery, relate in particular to a kind of restorative procedure of multi-parallel lithium ionic cell module.
Background technology
Along with the scarcity day by day of the fossil fuels such as oil, natural gas, and the deterioration increasingly of environmental pollution, electric automobile has obtained showing great attention to of people as a kind of clean type vehicles.Lithium-ion-power cell because it has extended cycle life, energy density is high, can high current charge-discharge, the advantage such as memory-less effect and environmental protection, become the main study subject of Prospect of EVS Powered with Batteries exploitation.Battery module for electric automobile is mainly through composing in parallel by a large amount of cells at present.Along with the operation of vehicle, if there have a battery to occur in battery module to be abnormal, will cause whole battery module to lose efficacy.
Existing for more the changing jobs of failed module, modal way is to become new module with new battery again combo, replaces failed module., there is certain drawback in this new battery method of combo again of all selecting.On the one hand, combo workload is larger again for new battery, and other module performance differences on new module and former vehicle may be larger.On the other hand, because indivedual batteries cause module extremely, lost efficacy, and if all changed, will cause all the other normal battery performances to fail to bring into play completely, and caused the use cost of power battery module high.Therefore, need to research and develop a kind of replacing operation simple, after changing, in vehicle, module consistency is higher, meanwhile, can reduce the power battery module restorative procedure of battery use cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of restorative procedure of multi-parallel lithium ionic cell module.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of restorative procedure of multi-parallel lithium ionic cell module, comprises the following steps:
(1) the initial combo information of trace back block and use information;
(2) sub-elect on request the module with the value of repairing;
(3) module is disassembled into cell;
(4) detect outward appearance, capacity, voltage, internal resistance and the self-discharge rate of cell, filter out defective battery;
(5) adopt the qualified battery of same model to replace the screened defective battery going out, by former module assembling mode, be reassembled into module.
As preferably, initial combo information and the use information of module described in step (1) comprise: initial capacity, initial internal resistance, service time, cycle-index, use historical record.
As preferably, described in step (2), have and repair the module being worth and refer to: module outward appearance, without distortion, discharges and recharges behavior without crossing, and module internal resistance is no more than 1.5 times of initial internal resistance, and module capacity is not less than 80% of initial capacity.
As preferably, described in step (4), defective battery refers to: battery outward appearance has distortion, and capacity is lower than 80% of initial capacity, and voltage is not in the scope of application of battery regulation, and internal resistance surpasses 1.5 times of battery initial internal resistance, the battery moon self-discharge rate surpass 5%.
As preferably, described in step (5), with the qualified battery of same model, replace the screened defective battery going out, the quantity that requires to be replaced battery is no more than 20% of number of batteries in former module.
The invention has the beneficial effects as follows:
First, use the qualified battery of same model, replace the screened defective battery going out, without combo again, greatly simplified module replacing operation; Secondly, module has only been changed the defective battery of minority, has guaranteed the new module performance after repairing, less with other battery module energy differences on former vehicle; Again, retain the good battery of former module performance, give full play to battery performance, reduce battery use cost.This restorative procedure is simple to operate, contributes to improve car load module consistency, reduces battery use cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the flow chart of the restorative procedure embodiment of multi-parallel lithium ionic cell module of the present invention.
Embodiment
As shown in Figure 1, a kind of restorative procedure of multi-parallel lithium ionic cell module, the repair process of 10 group 48 and battery module of take is example, concrete steps are as follows:
(1) the initial combo information of trace back block and use information.According to module numbering, inquiry record, the initial capacity of module, initial internal resistance, service time, cycle-index, use historical record etc.;
(2) sub-elect on request 8 groups of modules with the value of repairing.Sorting standard is, module outward appearance, without distortion, discharges and recharges behavior without crossing, and module internal resistance is no more than 1.5 times of initial internal resistance, and module capacity is not less than 80% of initial capacity;
(3) 8 pack modules are disassembled into cell, the cell of each pack module, indicates and deposits separately;
(4) detect outward appearance, capacity, voltage, internal resistance and the self-discharge rate of cell, filter out defective battery.Defective battery refers to, battery outward appearance has distortion, and capacity is lower than 80% of initial capacity, and voltage is not in the scope of application of battery regulation, and internal resistance surpasses 1.5 times of battery initial internal resistance, the battery moon self-discharge rate surpass 5%.
(5) pick out defective battery in every pack module, and record quantity.Having defective number of batteries in 1 pack module is 11, does not repair and is worth;
(6) adopt the qualified battery of same model to replace the screened defective battery going out, by former module assembling mode, be reassembled into 7 groups of new module.
The reparation of above-mentioned all batteries module is recorded as shown in table 1.
Table 1
