Example two
The embodiment of the present application provides a method for recovering a vehicle power battery, which can be applied to the vehicle power battery recovery system 1 shown in fig. 1-5, as shown in fig. 6 and 9, the method includes the following steps:
s201: and determining the components of the electric automobile according to the model of the electric automobile to be processed.
The qualified electric automobile has definite configuration, the specifications of all parts of the electric automobile can be inquired on a brand official website, so that the specifications of all the parts of the electric automobile can be inquired only by the type of the electric automobile, a worker manually inputs the type of the electric automobile or the system automatically identifies the type of the electric automobile through a camera, a statistical module enters the brand official website corresponding to the type to inquire the specifications of all the parts of the electric automobile after acquiring the correct type of the electric automobile, in addition, a form of the type of the electric automobile and the specifications of all the parts can be made in advance and stored in the system, the statistical module can inquire the components only by entering the form, the form is updated regularly, and the form can be updated synchronously if a new electric automobile is released.
If the electric automobile has replaced the part of the third party brand, at this moment, the part composition that the statistical module inquired is different from actual part composition, need to revise the part composition inquired, the revision method is similar, enter official website according to the model of this third party brand part and inquire, the concrete specification that will inquire is replaced can, save the result after finishing revising. If the third-party brand part cannot be inquired to obtain the detailed specification, the user or the working personnel can judge the third-party brand part according to the industry experience, and the residual performance of the third-party brand part can also be directly obtained.
S202: determining the action of each part in the normal running of the electric automobile, and setting the weight value of each part according to the action, wherein each part does not comprise a power battery.
The electric automobile comprises a motor, a power motor, a brake pad, a brake disc, a tire, a wheel hub, a frame, a chassis and the like. The motor comprises gears, bearings, speed reduction parts and the like. The method includes the steps that the weighted values of all components are set according to the action size of each component in the electric automobile, wherein the action size mainly refers to whether the component is a core component of the electric automobile or not, for example, the motor belongs to the core component, so that the components forming the motor can be set with larger weighted values, in addition, the components related to safe driving can be set with larger weighted values, for example, the components forming a braking system, other components can be set freely, the rest weighted values can be equally divided, it needs to be noted that the weighted values of all the components are not fixed values, and the sum of the weighted values of all the components or the components is 1.
S203: the remaining properties of the components are detected and recorded.
The power battery recycling system 1 for vehicles may be installed in a 4S shop or a repair shop of a vehicle, and the first detection module 103 is used for detecting the remaining performance of each component and the power battery, which is expressed in percentage.
For example, the residual performance of a tire is evaluated in terms of the degree of tread wear, which is 100% when the tire is new, and 0 when the tire has its tread worn flat, which decreases in equal proportion to the residual depth of the tread between new and worn flat.
In another case, a typical tire has a tire wear level mark, the position of which is between the above-mentioned brand-new and flat-ground positions, and if from a safer point of view, the position of the mark can be defined as the residual performance 0, and the position of the mark is generally 1.6 mm out of the tread depth, which means that the tire needs to be replaced to ensure safe driving.
For another example, the tooth surfaces of the gears have normal wear, pitting wear, adhesive wear and the like, the normal wear is the wear caused by mutual friction of the tooth surfaces in the meshing transmission of the gears, the wear occurs on the whole tooth surfaces, so that the tooth surfaces present uniform finish, when mechanical impurities in lubricating oil enter the friction surfaces, the mechanical impurities become abrasive wear to aggravate the wear, after the tooth surfaces are worn, the thickness of the gears is thinned, and the meshing gap is increased; pitting abrasion is mostly generated in a reference circle area of a tooth surface, when the compressive stress exceeds the yield limit of metal, fine fatigue cracks are generated on the tooth surface, and further metal particles on the surface are peeled off to form pitting-shaped pits; the adhesive wear is that when the rotating speed of the gear is very low and the load of the tooth surface is very large, because the distance of the contact part of the tooth surface is very small, the surface metals are mutually attracted and bonded together under the action of molecular attraction, or when the gear is under the conditions of adjustment, heavy load, poor lubrication, poor heat dissipation and the like, the contact part of the tooth top, the tooth root and the like is high in sliding speed, the generated high temperature enables the surface metals to be bonded together, the light person scratches, and the heavy person tears and damages the softer metal surface, the latter two can directly observe pocking marks and scratches or tearing marks when the wear is detected, wherein the fatigue peeling does not exceed 25 percent of the area of one tooth, the normal wear can be detected by using a gear vernier caliper, and the wear is generally the largest in the region of a reference circle, therefore, the gear vernier caliper is usually clamped at the reference circle to measure the thickness of the tooth chord of the gear to determine the wear condition of the gear, it can be seen that the residual performance of the gear is mainly evaluated by the tooth surface peeling area, the tooth tip degree and the thickness, and the residual performance of the gear is evaluated by the tooth surface peeling area, the tooth tip degree and the thickness, and other parts are also evaluated by the method.
If necessary, the component can be detached from the electric automobile for further detection, and the device for detaching the electric automobile is located in an automobile 4S shop or an automobile repair shop, and components such as tires, motors, power batteries and the like can be detached.
S204: and calculating the average residual performance of the electric automobile according to the weight values and the residual performance of each part.
Calculating the average residual performance of the electric automobile according to the weight value and the residual performance of each part, multiplying the weight value of each part by the residual performance of each part, and then summing to obtain the average residual performance of the electric automobile, wherein the average residual performance is also expressed in percentage.
The average remaining performance calculated above is the result of not including a power cell.
S205: and detecting the residual performance of the power battery.
When the residual performance of the power battery is detected, the appearance, the voltage and the internal resistance of the power battery are sequentially detected, the power battery with damaged appearance is not used, the power battery with unqualified voltage and internal resistance is not used, the power battery with qualified voltage and internal resistance is subjected to charge-discharge detection to obtain the capacity of the power battery, and the ratio of the detected capacity to the calibrated capacity can represent the residual performance of the power battery.
The detected capacity refers to the capacity of the power battery when the power battery is charged to saturation.
The appearance damage of the battery monomer has the following conditions, such as obvious visible damage of battery shell sinking, liquid leakage, corrosion and the like.
S206: and judging whether the residual performance of the power battery is smaller than the average residual performance.
The average residual performance of the electric automobile and the residual performance of the power battery are obtained before the step, the residual performance difference between the power battery and other parts can be obtained, and if the residual performance of the power battery is smaller than the average residual performance of the electric automobile, the fact that the performance of the power battery is seriously attenuated indicates that the power battery needs to be replaced.
S207: and if so, extracting the standby power battery matched with the average residual performance.
After the detection subsystem 10 determines that the power battery of the electric vehicle needs to be replaced, the detaching device first detaches the primary power battery from the electric vehicle, and the extracting module 201 extracts the backup power battery matched with the average remaining performance of the electric vehicle from the warehouse.
The matching means that the average residual performance of the electric automobile is close to the residual performance of the standby power battery.
S208: and replacing the primary power battery of the electric automobile with the standby power battery, and recovering the primary power battery.
The replacement module 202 then loads the extracted backup power battery into the electric vehicle, and places the primary power battery into a warehouse.
As shown in fig. 7, S2081: and judging whether the residual performance of the recovered motive power battery is less than or equal to the critical performance.

The present application is applied to an electric vehicle that performs energy compensation in a non-battery replacement mode, but is applied to an electric vehicle that performs energy compensation in a charging mode in which a power battery is integrated in a chassis. The weight values of the components in the table 1 are set to default weight values calibrated by manufacturers, and in the actual use process of the electric automobile, the weight values can be modified through a weight value adjusting module according to the actual use state of the automobile.
EXAMPLE III
Each part of the electric automobile comprises a vulnerable part and a damage-resistant part, and the sum of the weight values of the vulnerable parts is smaller than the sum of the weight values of the damage-resistant parts.
For the replaced wear resistant component, the remaining performance of the new wear resistant component after replacement is not counted into the average remaining performance calculation.
For the replaced wear-resistant part, the difference between the residual performance of the new wear-resistant part and the average residual performance of the electric vehicle is calculated.
And judging whether the difference is greater than or equal to a preset value.
If so, the residual performance of the new damage-resistant component after replacement is not counted in the calculation of the average residual performance.
Specifically, in this embodiment, a part that needs to be replaced within three years is defined as a vulnerable part, and the remaining parts are defined as wear-resistant parts, and the replacement frequency of the vulnerable part is generally greater than that of the wear-resistant part, so that the overall average remaining performance of the electric vehicle mainly depends on the wear-resistant part, and therefore when the weight values of the parts are set, the sum of the weight values of the vulnerable part is smaller than the sum of the weight values of the wear-resistant part.
