As new energy vehicle technology continues to evolve rapidly, range extender systems are becoming an increasingly important direction in the EV industry.
At the center of an efficient and reliable range extender system is a high-performance generator.
As a technology pioneer in China’s new energy motor industry, CHCD began investing in Hairpin motor technology as early as 2013. After 12 years of continuous development and technical refinement, CHCD has established a mature range extender generator technology system with stable mass production capability, providing efficient, reliable, and low-noise power generation solutions for global new energy vehicle customers.
For over a decade, CHCD has specialized in the core technologies of Hairpin motors, continuously improving:
- High power density
- High efficiency
- Low NVH performance
- Long service life
This long-term focus has enabled CHCD to build a complete technical system covering R&D, engineering, manufacturing, and validation.
CHCD has developed four dedicated new energy motor platforms: φ160, φ180, φ220, and φ270. Among them, the φ180, φ220, and φ270 platforms are already in stable mass production, covering a wide power range from 20kW to 320kW to meet various vehicle and application requirements.
All platforms utilize 4–10 layer Hairpin winding technology and support multiple winding solutions, allowing flexible customization and fast project adaptation for customers.
CHCD continues to advance independent manufacturing capabilities for key motor production processes, including:
- High-speed flat wire forming technology
- Multi-layer flexible wire twisting technology
- Headless direct welding technology
- High-precision automated production capability
The wire-end height difference is controlled within 0.2mm, while first-pass welding qualification exceeds 98%, ensuring highly consistent and reliable mass production quality. From winding forming, expanding, and twisting to precision welding, all core production processes are independently developed and manufactured in-house. Production cycle time is approximately 100 seconds per unit, achieving both high efficiency and strict quality control.
CHCD range extender generators are designed to deliver:
- High generation efficiency
- Low-noise operation
- High reliability and durability
- Stable performance under wide operating conditions
These advantages help provide continuous and stable power output for new energy vehicles, improving driving range performance and overall user experience. Supported by a mature platform architecture and professional engineering team, CHCD offers one-stop services from concept design and simulation analysis to prototype development and mass production, meeting diverse customer project requirements.
Backed by 12 years of technical expertise, CHCD remains committed to advancing core technologies for new energy power systems. Looking ahead, CHCD will continue investing in Hairpin motor and power generation technologies, delivering more advanced products, more stable quality, and more professional services to support the global new energy industry.
