With the increasing popularity of electric vehicles, number end-of-life (EOF) vehicle batteries (EVBs) is also day by day. Efficient dismantling and recycling EVBs are essential to ensure environmental protection. There many types with complex structures, current automatic line immature lacks corresponding equipment. This makes it difficult for some small parts be disassembled precisely. Screws used extensively in fix or connect modules EVBs. However, due size screws differences installation...

With the continuous promotion of electric vehicles, pressure to scrap vehicle batteries is increasing, especially in China, where nickel cobalt manganese lithium (NCM) have gradually come occupy a dominant position battery market. In this study, we propose two-stage pyrolysis process for batteries, which aims effectively deal with volatilization organic solvents, decomposition salts electrolyte and removal separator material polyvinylidene fluoride (PVDF) during recycling. By solving these...

In recent years, reputation management schemes have been proposed as promising solutions to alleviate the blindness during peer selection in distributed P2P environment where malicious peers coexist with honest ones. They indeed provide incentives for contribute more resources system and thus promote whole performance. But few of them implemented practically since they still suffer from various security threats, such collusion, Sybil attack so on. Therefore, how detect plays a critical role...

The main research direction for the disposal of spent lithium-ion batteries is focused on recovery precious metals. However, few studies exist recycling LiFePO4 electric vehicle (EV) because their low value. In addition, a detailed life cycle inventory (LCI) waste plays significant role in its assessment (LCA) an environmental perspective. this study, end-of-life (EOL) EV battery disposed to achieve LCI result. approach comprises manual dismantling pack/module and crushing pyrolysis cells....

Automobile shredder residue (ASR) pyrolysis produces solid, liquid, and gaseous products, particularly oil gas, which could be used as renewable alternative energy resources. Due to the primary reaction not being complete, yield of product is low. The tar comprises chemically unstable volatiles before condensing into liquid. Understanding characteristics volatile products will aid design improvement subsequent processes. In order accurately analyze chemical yields ASR pyrolysis,...

The vigorous growth of the electric vehicle industry calls for efficient disassembly used batteries (EVBs). Screw by robots remains a challenge due to uncertainties in this task. In paper, we designed an architecture NeuroSymbolic task and motion planning, which uses neural predicates map sensor into quasi-symbolic state schedules action primitives autonomously based on current goal state. This guarantees autonomy explainability is important human-robot hybrid pipeline. primitive...

Teeth detection and tooth segmentation are essential for processing Cone Beam Computed Tomography (CBCT) images. The accuracy decides the credibility of subsequent applications, such as diagnosis, treatment plans in clinical practice or other research that is dependent on automatic dental identification. main problems complex noises metal artefacts which would affect teeth with traditional algorithms. In this study, we proposed a teeth-detection method to avoid above accelerate operation...

Pyrolysis and gasification have gradually become the main means to dispose of automobile shredder residue (ASR), since these methods can reduce volume quality landfill with lower cost energy recovery be conducted simultaneously. As ASR pyrolysis process is integrated, results reactions organic components interaction among polymeric clarified by co-pyrolysis thermogravimetric experiments. The show that decomposition mechanisms textiles foam are markedly changed plastic in process, but effect...

The major factors affecting the popularization of electric vehicles (EV) are limited travel range and lack charging infrastructure. Therefore, to further promote penetration EVs, it is great importance plan construct more fast stations rationally. In this study, first we establish a pattern model based on Monte Carlo simulation (MCS). Then, with traveling data build bi-level planning stations. For upper model, an aim maximize success ratio, consider influence placement user’s route. We adopt...

This paper proposes a DNN-based distributed algorithm by deploying one DNN in each base station controller (BSC) to approximate the weighted minimum mean-square error (WMMSE) algorithm, which can allocate power parallel. Maximizing sum-rate is common problem setup for allocation single-input single-output (SISO) interfering broadcast channel (IBC). The WMMSE suboptimal and classical solution but has high computational complexity. Recently, proposed speed up approximating algorithm. Motivated...

Currently, there is no domain dictionary in the field of electric vehicles disassembly and other construction algorithms do not accurately extract terminology from text, because complex variable. Herein, a for research work that has important significance. Extracting high-quality keywords text categorizing them widely uses information mining, which basis named entity recognition, relation extraction, knowledge questions answers recognition extraction. In this paper, we propose supervised...

This paper focuses on the performance of IPM (Intelligent Power Module) under power cycling test which is simulated by a FEA (Finite Element Analysis) method. Through method control variables some key parameters about module's thermal and structure properties can be obtained.

The dynamic index and economic of battery electric vehicles are mutual related as well opposite. So they should be evaluated synthetically. From the analysis literatures, maximum speed, accelerating ability driving range chosen synthetic evaluation index. By method principal component analysis, model performance vehicle is established. And example used to explain application model.

"The essence of ideological and political course is to reason, we should pay attention ways methods, speak the truth deep, thoroughly alive" highlights importance "speaking" in teaching. As art "speaking", "questioning" can turn complex problems into several simple knowledge points, gradually show process generation logical relationship between so as improve effectiveness In specific application "Marxist Basic Principles", combine new media platform students 'learning autonomy; conduct...

Current OTS (Online Test System, OTS) of airborne electrical equipments in the environments mechanics is only able to test statically but dynamically. To solve problem, a new kind dynamic system based on PXI bus designed.
