Introduction
High-Voltage Power Distribution Units (HV PDUs) are critical components in electric vehicles (EVs), energy storage systems, and industrial equipment. As a leading HV PDU manufacturer in China, Keruixi integrates advanced technologies to meet global standards while offering cost-effective solutions. This article explores the core technologies behind PDUs and how Keruixi competes with international giants.
1. High-Current Handling Capacity
Technology:
- Keruixi PDUs support 500A+ continuous current with copper busbars and optimized thermal management.
- Compared to aluminum-based designs (common in low-cost PDUs), copper reduces resistance by 30%.
Keruixi Advantage:
- Customizable current ratings for different EV platforms (400V/800V/1500V/2300V).
- Tested under 100,000+ load cycles without degradation.
2. Modular & Scalable Architecture
Technology:
- Modular fuse/contactor slots allow flexible configuration (e.g., 6-channel to 12-channel).
Keruixi Advantage:
- Faster OEM integration (e.g., one PDU fits multiple models).
- Reduces R&D costs for clients
3. Advanced Thermal Management
Technology:
- Liquid-cooled heat sinks (for high-power apps) vs. air-cooled (standard).
- Phase-change materials used in extreme conditions.
Keruixi Advantage:
- Operates at -40°C to 125°C (wider range than other Connectivity’s typical -30°C to 105°C).
4. Lightweight Design
Technology:
- Aluminum alloy enclosures (vs. steel) with 30% weight reduction.
Keruixi Advantage:
- Ideal for weight-sensitive EVs (e.g., electric buses).
5. Smart PDUs with IoT Integration
Technology:
- Built-in current/voltage sensors + CAN/FlexRay communication.
Keruixi Advantage:
- Real-time diagnostics (e.g., predictive maintenance alerts).
6. Cost-Effective Localization
Technology:
- 100% China-based supply chain (vs. Aptiv/TE’s reliance on imports).
Keruixi Advantage:
- 20-40% lower cost than Western brands.
8. Rapid Prototyping & Customization
Technology:
- 3D printing + simulation tools for fast iteration.
Keruixi Advantage:
- 4-week lead time (vs. 12+ weeks for European vendors).
Why Choose Keruixi Over Global Competitors?
| Factor | Keruixi | International Brands (e.g., TE/Aptiv) |
|---|---|---|
| Cost | 20-40% lower | High (import tariffs, labor costs) |
| Lead Time | 8 weeks | 12-16 weeks |
| Customization | Full flexibility | Limited by global standards |
| Tech Support | 24/7 local team | Slow response (time zones) |
