Unlike traditional fuel vehicles, electric vehicles often have high voltage and current platforms, so there are often a large number of high -voltage connectors on new energy vehicles. From the perspective of the connector itself, there are many classification types of ev connectors: For example, there are round, rectangular, etc. from the shape, and there are high -frequency and low frequencies i...
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 ...

Foreword With the rapid development of Industry 4.0, the application scenarios of electrical connectors and sensors are increasing. As one of the key components of signal and data transmission, industrial cable assemblies also have strict requirements for signal transmission, on -site protection, and convenient installation. Accompanied by customers' demand for industrial cable assemblies, it is m...
What is a RF connector? The radio frequency connector is defined as: a separate component that is usually installed on a RF cable assemblies or device for the electrical connection of the transmission system. It can be seen from this definition that it has the common characteristics of the "separated element" connection. Taking the commonly used coaxial axis as an example, the main model of...
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...
