Technical Field

[0001] This utility model belongs to the field of new energy vehicle parts, specifically relating to an intelligent high-voltage wiring harness. Background Technology

[0002] The rapid development and technological advancements in new energy vehicle technology: As new energy vehicle technology continues to advance, high-voltage wiring harnesses, as a key component of new energy storage systems, directly impact the safety and efficiency of the entire system. Therefore, the technological level of high-voltage wiring harnesses is constantly improving to meet the demands of new energy vehicles for high safety, high efficiency, and long lifespan. Material innovation: To adapt to the high-voltage environment of new energy vehicles, high-voltage wiring harnesses utilize materials with high temperature resistance and high shielding performance, such as copper alloy wires and brick-bonded insulation materials. The application of these new materials not only improves the electrical performance of high-voltage wiring harnesses but also enhances their durability and stability.

[0003] High-voltage wiring harnesses play a crucial role in new energy vehicles, primarily in power transmission. They are responsible for transferring electrical energy from the battery pack or other power sources to the motor, motor controller, and other high-voltage electrical equipment to drive the vehicle. These harnesses must be able to withstand high-voltage power and ensure its safe and stable transmission. They also provide protection, detecting and responding to faults and abnormalities in the vehicle's electrical system, such as short circuits, overloads, and overvoltages, through high-voltage interlocks. This allows for timely power cut-off or other measures to protect the vehicle's electrical equipment and passenger safety.

[0004] In summary, the application background of intelligent design for high-voltage wiring harnesses in new energy vehicles is the rapid development of new energy vehicle technology and the continuous growth of market demand. With the continuous development of the new energy vehicle industry and the continuous progress of technology, the application of intelligent design for high-voltage wiring harnesses in new energy vehicles will become increasingly widespread, and its requirements will become increasingly stringent. During the application of high-voltage wiring harnesses in new energy vehicles, problems such as poor contact, overcurrent, overvoltage, and overheating frequently occur, leading to wiring harness erosion. Some problems have clear causes and are easy to troubleshoot, and software protection strategies can prevent some safety issues from occurring. However, despite these advantages, some problems remain with unclear causes, requiring significant manpower and resources to find the root cause, and in some cases, the entire vehicle even catches fire and is destroyed, posing a significant challenge to subsequent investigation.
