The industrial joints hidden within 30kW modules are supporting China's supercharging network.
In today's era of booming demand for fast charging in new energy vehicles, 30kW air-cooled/liquid-cooled charging modules are no longer just technical samples in laboratories. They are the "power cells" surging in charging stations on national highways, core urban business districts, and integrated photovoltaic-storage-charging microgrids in industrial and commercial parks. They output power 24/7, supporting single-pile supercharging capabilities of 120kW, 240kW, or even megawatt-level.
But few people pay attention: when 85A current surges under 1000V high voltage, and when equipment repeatedly switches between extreme cold of -55℃ and high temperatures of +125℃, what truly determines the long-term stable operation of the system is often not the main control chip, but those overlooked millimeter-level connection components – they are like the "joints" of the human body, small yet bearing weight, durable, and corrosion-resistant.
🔌 M4 Screw: The "First Line of Defense" for System Fastening
Model: YHR8.222.1034 | Part Number: 80-222-01034
Carbon steel material + nickel-zinc alloy plating, passed 240-hour salt spray test. Recommended torque 1.5N·m, minimum destructive torque reaches 3N·m – in coastal high humidity or northern de-icing salt environments, it still firmly locks the module and the casing, preventing temperature rise or arcing caused by loosening.
🔌 φ5 Copper Terminal: The "Golden Channel" for High Current
Model: MPC-5G01 | Part Number: 60-571-01068
Gold-plated crown spring structure + beryllium copper base material, contact resistance ≤0.5mΩ, continuously carrying 80A current. Tensile strength after crimping ≥1500N, with a positioning anti-detachment design, it remains as stable as a rock even under 490m/s² vibration impact.

🌐 Conclusion: Reliability is the sum of countless details
In an era of rapid advancement in fast-charging infrastructure, true technical strength is not only reflected in power figures but also hidden in the plating of every screw, the contact surface of every terminal, and the smoothness of every plug-in. Choosing an engineering-verified high-specification connection solution is like pre-insuring for ten years of operational stability.
