Testing cables at high voltages can help determine the presence of moisture, flux, or contaminants that may have penetrated the insulation or connector backshell breaks, and ensures that the insulation between wires can withstand temporary voltages higher than the normal working voltage offset without decomposing. The results of the high-voltage test usually show the insulation resistance between ...

I. Ultrasonic welding principle: Ultrasonic wiring harness welding is a commonly used process of car wire welding. The principle is to re -combine the surface of the welding material through high frequency vibration. Ultrasonic welding energy consumption is low, no pollution, strong welding and low internal resistance, and does not change the chemical properties of welding parts. Welding cond...
HV Cable selection 1. Cable diameter According to the layout diagram of each high-voltage electrical component of the vehicle, the main circuit and branch circuit are distinguished, and the responsible characteristics of the high-voltage components connected to the high-voltage wiring harness are determined. Characteristics include working voltage, rated power, peak power, rated current, peak curr...
The European electric vehicle charging standard CCS2 is a combined standard that integrates AC charging and DC charging. The combined charging system is an open international standardized system, mainly promoted by Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen. Vehicles exported to Europe need to meet their physical interface and communication requirements. Euro...
The charging system can be divided into two methods: conventional charging and fast charging. From the perspective of appearance and size, the difference between the charging ports is actually very simple. The fast charging port is large and has 9 holes (two large holes, one middle hole, and 6 small holes). The slow charging port is small and has 7 holes (5 large holes and 2 small holes), so that ...
Connectors are used in every car. The device uses signals such as electricity and light to control the corresponding mechanical force to connect, disconnect, and convert, and then realizes a functional element of the corresponding circuit or optical channel conversion, and With the help of ECT electrical and optical signals, signal distortion and corresponding energy loss can be effectively preven...
When consumers are looking to purchase an EV, the time it takes to charge an EV continues to influence their purchasing decision. Today, the fastest way to charge an electric vehicle is high-power direct current (DC) fast charging. DC fast charging, unlike AC charging, requires specific OEM considerations when designing critical components of the vehicle's electrical architecture, such as charging...
Automotive wiring harness is one of the important components of the automotive electrical system, it is woven by a number of thin wires in a specific way, like a thin wire connected to the various electrical equipment on the car color code represents the different functions and uses of these thin wires, Aichi science and technology team for you to introduce the meaning of the car wiring harness co...
With the development of society and the continuous improvement of people's environmental awareness, new energy vehicles have become a new trend in the development of the automobile industry. Among the new energy vehicles, the development speed of electric vehicles is very rapid. At the same time, the electric energy used by electric vehicles is a large-capacity, high-voltage electrical energy, whi...
A copper conductor consists of a single copper wire or multiple copper wires(electric wire), which are described as follows: Hard copper wire: cold processed by stretching wire, with high tensile strength, suitable for overhead power cables, distribution wires and building wires conductor. Soft copper wire: hard copper wire is heated to remove the residual stress generated by cooling processing, r...
