Our products are designed with core concepts of high reliability, lightweight, easy integration and long service life, fully considering the harsh working conditions of new energy scenarios, and strictly following the full life cycle reliability design standards to provide stable and cost-effective connection solutions for customers.
The core working principle of battery wire harness is based on high-insulation temperature-resistant material modification and modular high-voltage connection architecture, to achieve low loss and high insulation reliability under high-power transmission. The complete implementation logic chain is as follows:
1. Conductor layer: Made of multi-strand finely stranded tinned copper wire, to reduce skin effect under high-frequency transmission, and improve current carrying efficiency and flexibility.
2. Insulation layer: Made of modified silicone/fluoroplastic material, resistant to -40℃ to 150℃ wide temperature range, with VW-1 flame retardancy and low smoke zero halogen environmental performance.
3. Crimping layer: Adopting precision terminal crimping process, controlling crimping height and tension tolerance, to reduce contact resistance and avoid heating risk under high current.
Based on the underlying principle, we have innovatively optimized the system architecture with modular design, improving product performance, stability and scenario adaptability. The core architecture includes:
1. High-flexibility conductor module: Adopting cage stranding machine precision stranding process, achieving a minimum bending radius of 4-5 times the cable outer diameter, adapting to automated assembly and narrow space wiring.
2. Full-link compliance control module: Full process traceability from raw material incoming inspection to finished product delivery, meeting hazardous substance control and industry certification requirements.
Compared with traditional hard cable solutions, our technology has achieved core breakthroughs as follows:
1. Traditional hard cables have large bending radius and high automated processing labor hours. Our high-flexibility design reduces bending processing labor hours by 32%, and increases single production line daily capacity by 28%.
2. Traditional cables are prone to aging and short circuit under wide temperature and vibration conditions. Our material modification design reduces cable aging short circuit faults by 75%, and reduces overall equipment after-sales repair rate by 62%.
All parameters of our battery wire harness are strictly tested in accordance with IATF16949 and UL2263 standards, with clear test conditions and strict tolerance control. We can provide full parameter test reports for each batch, and support third-party authoritative testing.
