Freight and sanitation tricycles often face changing loads, difficult hill starts, and motor overheating. Sudden current changes can cause jerky movement or power interruptions, increasing repair costs.
The Avetlink AK dual-row controller uses coordinated dual-core control. A 32-bit ARM main processor controls the motor, while a second processor monitors the battery and manages protection. Together, they adjust power delivery as the load changes.
The original description reports 15% more climbing torque and smoother starts and stops.
Power Control for Heavy Loads
In the supplied example of a tricycle carrying 1.5 tonnes, constant-current control keeps the difference between stall current and running current within ±5%. This is intended to reduce power interruptions caused by sudden battery voltage drops.
Electronic Braking and Energy Recovery
The system includes EABS electronic braking and regenerative charging. The source reports:
- 30% shorter braking distance on ice and snow.
- 8–10 km more driving range.
- 20% longer lead-acid battery service life.
Energy recovery efficiency is listed as 18% in the overview and greater than 18% in the feature specifications. These figures need clarification before publication.
Motor Compatibility
The controller automatically identifies 60° / 120° Hall configurations. The supplied description claims compatibility with 90% of electric tricycle motors and a 50% reduction in replacement costs.
Actual compatibility depends on the motor’s electrical specifications and wiring.
Key Features
- Dual-core control: Separates motor control from battery protection.
- High-speed motor support: Supports motor speeds up to 20,500 rpm.
- Fast protection response: Stated overcurrent response time is less than 10 ms.
- Wide temperature design: The source lists −40°C to 125°C. Whether this refers to ambient operating temperature or component temperature needs confirmation.
Maintenance and Matching Tips
1. Motor matching: The source recommends a phase-angle tolerance of ≤0.5° for heavy-duty motors. Confirm the measurement and matching requirements with the motor supplier.
2. Heat-sink cleaning: Clean the aluminum housing’s cooling fins every month. The source reports a 15°C reduction in operating temperature after cleaning under hot conditions.
Reference Applications from the Supplied Text
- Delivery fleets: For tricycles traveling 200 km per day, reported average controller failures fell from 3 per month to 0.5 per month.
- Sanitation vehicles: For garbage collection vehicles working on slopes, reported start-stop smoothness improved by 90%, while annual battery replacement costs fell by RMB 1,200 per vehicle.
The Avetlink AK controller combines load-responsive motor control, battery protection, and energy recovery for compatible freight and sanitation tricycles.
