Decoding Yiwei’s New Energy Sanitation Vehicle Testing: A Comprehensive Process from Reliability to Safety Validation

To ensure every vehicle leaving the factory meets the highest standards, Yiwei Motors has established a rigorous and comprehensive testing protocol. From performance evaluations to safety verifications, each step is meticulously designed to validate and enhance the vehicle’s performance, reliability, and safety across all dimensions.

I. Performance Testing

1. Range Testing:
   • Tests the vehicle’s range under various conditions (full load, no load, urban roads, highways) at 100% State of Charge (SOC).
   • 
   • 
2. Power Performance Testing:
   • Evaluates acceleration metrics:
     • 0-50 km/h, 0-90 km/h, 0-400 meters, 40-60 km/h, and 60-80 km/h acceleration times.
   • Tests climbing capability and hill-start performance on gradients of 10° and 30°.
   • 
3. Braking Performance Testing:
   • Measures braking distance and stability from 60 km/h to 0 and 30 km/h to 0 under full-load conditions.
   • 

II. Environmental Durability Testing

1. Temperature Testing:
   • Conducts full performance evaluations of the battery and vehicle in extreme temperatures (-20°C and 40°C), complying with National Standard GB/T 12534 – General Rules for Automotive Road Test Methods.
   • 
2. Salt Spray & Humidity Testing:
   • Simulates high-salt and high-humidity environments to assess corrosion resistance of components and paint durability.
   • 
3. Dust & Waterproof Testing:
   • Subjects vehicles to 2 hours of pressurized water spray in a dedicated facility to validate dust/water resistance.
   • 

III. Battery System Testing

1. Charge/Discharge Efficiency Testing:
   • Evaluates battery charging/discharging efficiency and cycle life to identify and resolve potential issues.
2. Thermal Management Testing:
   • Assesses battery performance across a wide temperature range (-30°C to 50°C) to ensure stability in all climates.
3. Remote Monitoring Testing:
   • Validates the practicality and accuracy of remote monitoring systems for real-time issue detection and resolution.

IV. Functional Safety Testing

1. Fault Diagnosis Testing:
   • Tests diagnostic and early warning systems to preemptively identify and address vehicle faults.
2. Vehicle Security Testing:
   • Evaluates remote monitoring capabilities to ensure comprehensive safety oversight.
3. Operational Efficiency Testing:
   • Optimizes workflows by testing vehicle performance across diverse operating conditions.

V. Specialized Sanitation Testing

1. Waste Collection Testing:
   • Assesses garbage compaction and collection system reliability during operations.
2. Noise Level Testing:
   • Measures operational noise to comply with National Standard GB/T 18697-2002 – Acoustics: Measurement of Noise Inside Motor Vehicles.
3. Long-Term Durability Testing:
   • Simulates 2×8-hour non-stop operation to evaluate system endurance and stability.
   • 

VI. Reliability & Safety Validation

1. Fatigue Testing:
   • Tests critical components under prolonged stress to identify wear and mitigate risks.
2. Electrical Safety Testing:
   • Ensures electrical system integrity to prevent leaks, short circuits, and other hazards.
3. Water Wading Testing:
   • Evaluates waterproofing and insulation in water depths of 10mm-30mm at speeds of 8 km/h, 15 km/h, and 30 km/h.
4. Straight-Line Stability Testing:
   • Validates stability at 60 km/h to ensure safe driving dynamics.
5. Repeated Braking Testing:
   • Tests braking consistency with 20 consecutive emergency stops from 50 km/h to 0.
6. Parking Brake Testing:
   • Verifies handbrake effectiveness on a 30% gradient to prevent rollaways.
