Product Advantage
1. OE-Level Manufacturing Experience with Proven Expertise
Backed by 18 years of specialized experience in Chery-specific auto electrical parts, our car alternator for Chery adheres to strict OE (Original Equipment) standards. We’ve supplied over 500,000 units to global Chery aftermarkets, with a customer repurchase rate of 78%—a testament to our deep understanding of Chery’s electrical system demands. This expertise ensures every alternator matches the fit and performance of factory-installed parts.
2. High-Efficiency Power Conversion for Optimal Performance
Equipped with advanced copper-clad aluminum windings, our Chery car alternator achieves a 96.5% power conversion efficiency—5% higher than the industry average (91.5%). It efficiently converts engine mechanical energy into stable electrical power, meeting the energy needs of on-board electronics (e.g., infotainment, lighting) while reducing fuel consumption by up to 2%. This efficiency makes it a cost-effective choice for long-term use.
3. Direct-Fit Design for Hassle-Free Installation
As a Chery-specific alternator, it adopts a direct-fit structure that aligns perfectly with Chery’s original mounting points and electrical connectors. No extra modifications or adapter parts are needed, cutting installation time from 2+ hours (for universal alternators) to 45 minutes or less. This feature saves time for repair shops and reduces installation costs for end-users.
4. Stable Voltage Output with Intelligent Protection
Built-in intelligent voltage regulator maintains output voltage at 13.8-14.4V (±0.2V), preventing voltage fluctuations that damage on-board electronics (e.g., batteries, ECUs). It also integrates overload and short-circuit protection—automatically cutting off excess current when the load exceeds 120% of rated power. This ensures safe and reliable operation even in harsh usage scenarios.
5. Globally Recognized Quality Certifications
Our Chery car alternator is certified by ISO 9001 (quality management), IATF 16949 (automotive quality), and CE (safety). Each unit undergoes 12+ quality inspections (from raw material testing to final performance verification) before leaving the factory, with a defect rate controlled below 0.03%. These certifications ensure compliance with global auto parts standards, facilitating smooth import for overseas customers.

Product Uses
Here are specific application scenarios of car alternator:
1. Daily Urban Commuting
Ideal for daily city driving (1-2 hours/day on average). Its 96.5% power conversion efficiency ensures stable power for on-board electronics (navigation, air conditioning) without overloading the engine. Reduces fuel consumption by 2% vs. ordinary alternators, cutting daily commuting costs.
2. Long-Distance Highway Travel
Perfect for 4+ hour highway trips. With ±0.2V stable voltage output, it prevents sudden power fluctuations that damage infotainment or lighting systems. 6,000+ hour service life handles frequent long journeys, avoiding breakdowns midway.
3. Extreme Climate Conditions
Suitable for regions with -40℃ to 150℃ temperature variations. Class H insulation and corrosion-resistant zinc-plated housing pass 500-hour salt spray tests, ensuring reliable operation in humid coastal areas or dry, hot deserts.
4. Commercial Fleet Operations
Tailored for commercial vehicles (300+ working hours/month). High-current options (80A/100A/120A) meet the power needs of multiple on-board devices (GPS trackers, refrigeration units). 0.03% low defect rate reduces fleet maintenance downtime.
5. Aftermarket Repair & Replacement
Essential for Chery aftermarket repairs. Direct-fit design cuts installation time to 45 minutes (30% faster than universal alternators). OE-matching specs and IATF 16949 certification ensure it replaces original parts seamlessly, trusted by 80% of local auto repair shops.
Product Operate Guide
Pre-Installation Check: Ensure the vehicle engine is off. Verify the alternator’s connector matches your Chery’s OE plug (no adapter needed). Wipe clean mounting points to avoid dust affecting fit.
Installation: Align the alternator with original bolt holes, fasten (torque: 25-30 N·m). Connect the wiring harness securely—wrong polarity may damage components.
Post-Use: Check voltage (13.8-14.4V) monthly with a multimeter. Clean the housing quarterly to maintain heat dissipation; avoid water immersion (IP6K9K rating resists splashes, not submersion).
