In the actual situation, because of the shock of automobile in the movement process and the wire harness in undulating tube placement is random, leading to the relative position of the wire harness is not fixed, Thus lead to crosstalk value has certain dynamic range. In this paper, obtained the unit mutual inductance and mutual capacitance of wire with insulation layer using mirror image method, simulation and prediction of crosstalk dynamic interval by statistical simulation method, obtain harness near end crosstalk changes range within 3dB at a confidence level of 80%. This provides a reference for EMC design of automotive wiring harness.

AbstractElectric vehicles (EVs) are without a doubt one of the hottest topics of our time because of their advantages over combustion engine vehicles. This has persuaded many developers to try improving EVs so they will be more reliable and cheaper and as a result suitable for a broader range of consumers.In this paper we dive into the proper way of measuring and understanding the impedance of one prismatic cell from 100 kHz up to 1 GHz. Some common measurement mistakes and important points to notice are also explained. The effect of a power bar is shown as well. In order to make sure of the accuracy and the consistency of the measurements, they are compared with finite element simulations as well as with mathematical calculations.Investigations of conducted emissions are also of key importance since it has a direct influence on selecting a suitable frequency range. Accordingly, a thorough lab measurement is conducted to see the distortion harmonics and their influence on the carrier frequency. This knowledge can then be used to implement the power line communication (PLC) method.The PLC technique helps us to reduce the wire harness of a battery pack by using the existing high-voltage lines of the vehicle as the main transmission channel. This leads to cheaper battery packs by reducing the amount of used material for the wire harness and production time as well as assembly complexity.

Abstract The Eight Disciplines (8D) is a problem-solving technique methodology to identify the root cause of a problem, devise a short-term fix and implement a long-term solution to prevent recurring problems. 8D is a remarkable first step to enhancing Quality and Reliability when the product is defective or not satisfying the customer. The study was conducted in a manufacturing company producing and assembly wire harness. The data was collected for a period of Three months from July 2020 to September 2020, to identify defective percentage of wire harness and they were found to be high at the average rate of 51.39%. In this work the objective was set to investigates quality issues and provides a solution to reduce the rejection of wiring harness mainly in crimping process. In order to achieve this, 8D problem solving technique was used to analyze and solve the problem. Then, Pareto analysis was done to identify vital causes contributing defectives. From the Pareto analysis, it was found that functioning contact crimp condition with percentage 66.67% is the major cause for rejection. Further brainstorming sessions was held to identify the root causes. After the brainstorming session, cause and effect diagram was constructed and it was found to be variation in the that the connector near cable chain is moving area. Thus, the wire assembly with too high radius may caused external force to the wires when machine running with speed and the end of wire may break off when the wire stretched. The suggestions to reduce the rejection percentage were to install mounting bracket prevent wires shaking when machine running and use proper crimp tools. After implementing the suggestion, the total rejection for wire harness particularly contact crimp condition was reduced to 0.93% in December 2020, from average rejection of 66.67%. (3 months data).
