This article mainly introduces the composition and role of high-voltage systems in new energy electric vehicles The composition of the high-pressure system In the new energy electric vehicle, the parts with high voltage of the whole vehicle include power battery, drive motor, high-voltage distribution box (PDU), electric compressor, DC/DC, OBC, PTC, high-voltage wiring harness, etc., […]

The high-voltage interlock function is also an important function on the BMS, and other high-voltage controllers will also have this function, such as VCU, etc.; its function is to detect the connection status of the High Voltage Interlock Connector in the high-voltage circuit and identify the high-voltage connector is not connected Or accidental disconnection failure; As shown

General power connectors are specifically designed to transfer power from one device to another or from one point to another point in the same device. This type of connector usually has relatively high voltage, current, and temperature ratings. Let’s explain the next common power connector, called DC power connector. Overview of DC power connector knowledge：

When we get a motherboard, we must first understand the usefulness of the slots on the motherboard. Only when you know it, can you know it well. On the motherboard, you can find a rectangular slot on the edge. The interface with 20 or 24 jacks is the power supply interface for the motherboard. If

D-type connectors have been widely used for many years. They were originally developed by Cannon in 1952 and are now part of CanT. The D-type connector has been used as a multi-way connector in many applications, but it is probably the most widely known connector for RS-232 serial links. In fact, D-type connectors have been

1.2.2High voltage interlock (HVIL) In terms of the entire high-voltage interconnection system, in order to ensure the safety of the high-voltage system when it is powered on and off, the concept of high-voltage interlock is introduced in the connection design. The simple description is that when the connector is plugged and turned on, the high-voltage

Application parameters of high-voltage connectors in automobiles (1) Use position: As the name suggests, it is the application position of the connector on different high-voltage electrical appliances in the vehicle. Choose the connector. (2) Rated voltage: the maximum voltage at which electrical equipment (including electricity and power supply equipment) can work stably for a long

Precautions for the installation of high-voltage connector sockets (1)The voltage selection needs to be matched: the rated voltage of the whole vehicle after load calculation should be less than or equal to the rated voltage of the connector. If the working voltage of the whole vehicle exceeds the rated voltage of the connector for a long

How to choose a circular connector? What are the selection criteria for circular connectors? 1. Circular connector bayonet type: When choosing a circular connector, pay attention to choosing a suitable and matching bayonet type, mainly including 1/4 fast bayonet connection, plug-in connection, latch connection, fast Plug-in connection, threaded connection, zipper connection, etc.; 2. Connection mode

Industrial circular connectors can also be called circular aviation plugs, circular aviation plugs or circular interconnects. They are multi-pin electrical connectors with a cylindrical basic structure and a circular mating surface. In the interconnection category, It belongs to category 5 and is used for interconnection between devices. Industrial circular connectors include contacts for transmitting data and power,
