The Value of New Energy Vehicles and Liquid-Cooled Connectors
Challenges Unique to New Energy Vehicles
- Power batteries experience a sharp rise in temperature during fast charging, which affects both charging speed and battery life.
- Space for vehicle assembly is extremely limited, making it difficult to connect the piping.
- Continuous vibration while driving (road spectrum excitation) can cause joints to loosen and leak
- The 800V high-voltage platform has extremely strict requirements for insulation against liquid leakage, as leakage can lead to insulation failure.
- The final assembly line has a fast cycle time, but piping connections are inefficient.
- After-sales repairs require disconnecting the cooling lines; the traditional method is prone to fluid leaks.
Liquid-Cooled Fitting Solutions
- High-Efficiency Heat Dissipation Channel: A liquid-cooled plate combined with quick-connect fittings forms a low-resistance circuit, enabling rapid cooling of the battery pack during 2C to 6C fast-charging scenarios.
- Compact, miniaturized design: Available in right-angle, straight-through, and multi-channel configurations, with an overall length 20%–30% shorter than traditional solutions, making it suitable for the confined spaces within battery packs.
- High Vibration Durability: Passed vibration testing equivalent to 200,000 kilometers of road driving; mechanical shock resistance of ≥50g; anti-loosening structural design.
- High-Voltage Safety Redundancy: Dual-layer sealing + conductive grounding design, insulation resistance ≥ 100 MΩ, and withstands 3,000 V AC during dielectric strength testing.
- One-touch quick connect/disconnect: One-handed operation, insertion force ≤ 30 N, dual tactile and audible feedback upon proper connection, and a 50% increase in production efficiency.
- Leak-free shutoff: When shut off, the double-ended valve closes within 0.01 seconds, with residual leakage ≤ 0.05 ml; no fluid replenishment is required after maintenance.
Key Product Advantages
Compatible with mainstream coolants; suitable for new energy thermal management systems
Compatible with ethylene glycol-based coolants (20%–50% concentration), deionized water, and air conditioning refrigerants (R134a/R1234yf), among others. The material is hydrolysis-resistant and does not leach.
Optimized bore design for low flow resistance and high flow rate
The valve core flow path has been optimized based on the performance curve of electric water pumps, resulting in a 15% to 20% reduction in pressure drop for the same nominal diameter, which reduces the pump’s power consumption and extends the driving range.
Fully automated production line assembly, ensuring consistency at the million-unit level
Critical seals undergo automated assembly and 100% airtightness testing, with a CPK of ≥1.33, meeting automakers’ zero-defect delivery requirements.
Complies with automotive-grade certification standards for new energy vehicles
Certified under the IATF 16949 system, compliant with PV standards, and already integrated with the thermal management platforms of several major automakers.
