New energy connectors play a crucial role in new energy systems, with their main functions covering power transmission, signal and data communication, charging system connection, temperature control management, and system integration. First, new energy connectors are responsible for connecting core components such as batteries, inverters, and motors to enable efficient power transmission, withstand high currents and voltages, and ensure system safety and stability. Additionally, the connectors handle signal and data transmission tasks, connecting the battery management system (BMS), vehicle control unit (ECU), and other devices, transmitting key information such as battery status, temperature, and voltage in real time to support intelligent monitoring and regulation. In the charging system, new energy connectors connect the charging pile to electric vehicles, supporting various standards like DC fast charging and AC slow charging, ensuring stable and safe power transmission during the charging process. At the same time, as the power of new energy devices increases, connectors also play a role in cooling systems, helping to transfer coolant and maintain the equipment at an appropriate temperature to prevent overheating and system failure. Finally, the modular design of new energy connectors allows integration of power, signal, and data transmission functions, enhancing system flexibility and scalability, simplifying installation and maintenance, and meeting complex application needs. The multifunctional capabilities of new energy connectors ensure the efficient and safe operation of new energy systems. As technology advances, their functions will continue to expand and improve, driving the development of the new energy industry.
