One of the most important components in electrical systems is Industrial Tungsten Rivets for Contacts, which directly affects the stable transmission of current and the operating efficiency of equipment. In these high-load and high-temperature environments, tungsten contacts have become an ideal choice due to their excellent performance, especially in electrical connections, contacts and high-frequency components, where tungsten contacts play an irreplaceable role.
Unique properties of tungsten contacts
Tungsten materials have many special physical properties that make them widely used in the electrical systems of new energy vehicles. First, tungsten has a melting point of up to 3410°C, the highest melting point of all metals. This feature enables tungsten contacts to maintain their structural stability in high-temperature environments, preventing electrical connection points from melting or failing at high temperatures. Tungsten contacts can provide stable and reliable electrical connections in high-temperature working environments such as battery management systems, motor controls, and charging systems.
Second, the thermal expansion coefficient of Industrial Tungsten Rivets with Contacts is very low, which means that its size changes very little when the temperature changes, which can effectively cope with the frequent temperature fluctuations of electrical equipment in new energy vehicles. This feature is essential to ensure the long-term stability of the electrical system, especially in working environments with drastic temperature changes.
In addition, tungsten contacts also have excellent corrosion resistance and high conductivity. Under high load current, tungsten can effectively reduce the resistance of electrical contacts, reduce energy loss, and improve current transmission efficiency. At the same time, tungsten's anti-oxidation properties enable it to maintain long-term stability in complex environments, avoiding poor contact caused by oxidation or corrosion of contacts.
Application of tungsten contacts in new energy vehicle electrical systems
Battery connections and high current contacts
In new energy vehicles, high current transmission is required between battery packs and motors. Iron Tungsten Contact Rivets are widely used in battery connectors and high current contacts. The high conductivity and high temperature resistance of tungsten contacts can ensure stable current transmission under high load current, avoid heat and energy loss caused by excessive resistance, and thus improve the power performance and endurance of the vehicle.
Battery Management System (BMS)
The battery management system (BMS) is a vital part of new energy vehicles, responsible for monitoring the charge and discharge status and temperature of the battery. Tungsten contacts are often used as BMS connection points due to their high temperature resistance and wear resistance. Tungsten contacts can work stably in an environment with high-frequency current and temperature fluctuations, ensuring efficient and reliable operation of the battery system.
Connection between motor and electronic control system
The connection parts of the motor and electronic control system need to withstand long-term high temperature and high-load operation. The use of Car Horn Tungsten Contact Rivets can effectively reduce the contact resistance in the electrical system, reduce the poor contact or overheating problems caused by high temperature or current fluctuations, and thus ensure the long-term stability and reliability of the motor and electronic control system.
On-board electronic control system
With the increasing intelligence of new energy vehicles, the on-board electronic control system contains a large number of high-frequency control signals and data transmission. Tungsten Copper Electrical Contact plays an important role in these electronic control systems due to its excellent conductivity and high-frequency stability. It can ensure the efficient transmission of current and signals, avoid signal attenuation or interference caused by insufficient material performance, and thus improve the response speed and working accuracy of the on-board system.
