DR - Double-station Unicycle Aging Test System

The dual-station unicycle aging test system is an intelligent parallel aging detection device specifically designed for electric unicycles (balance wheels, self-balancing scooters). By simulating long-term high-load operation, temperature and humidity cycles, and dynamic impact scenarios, it simultaneously conducts accelerated aging tests on two unicycles to comprehensively verify their battery life, motor stability, control board reliability, and structural durability. This system is widely used in manufacturing, R&D laboratories, and certification institutions to ensure that products comply with international safety standards such as UL 2272, EN 15194, and GB/T 36676, thereby reducing user safety risks caused by aging failure.

Application scope

Used for unicycle aging tests 

Core functional modules 

Dual-station parallel aging test

Independent control stations: Two stations operate independently, allowing for the setting of different aging parameters (load, temperature, operation mode) without interference.

Dynamic load simulation: The motor loading system simulates riding resistance (torque range 0~50N·m), supporting the reproduction of uphill, acceleration, and bumpy road conditions.

Environmental coupling accelerated aging

Temperature and humidity cycle test:

1. Temperature range -20℃~+70℃, humidity 10%~95% RH, to verify battery high-temperature degradation and low-temperature start-up performance.

2. Supports day-night temperature difference cycles (e.g., 25℃↔55℃, with ≥100 cycles).

Vibration and shock test: Random vibration (5~200Hz, acceleration 5g) simulates long-term bumpy road damage to internal components.

Intelligent monitoring and diagnosis

Real-time multi-parameter collection:

1. Electrical parameters: Battery voltage/temperature, motor current, controller efficiency (accuracy ±0.5% FS).

2. Mechanical parameters: Hub speed (0~2000rpm), vibration spectrum, housing deformation (laser distance measurement ±0.1mm).

Fault warning and recording:

1. AI algorithm identifies anomalies (such as battery overvoltage, motor overheating), automatically stops the machine and generates a fault report.

2. Data cloud storage, supporting MES system integration and batch traceability.

2. Optional salt spray corrosion module (ASTM B117), dust and water resistance test (IP67).

Safety protection:

1. Independent overcurrent/overvoltage/over-temperature protection, emergency stop button, compliant with ISO 13849 mechanical safety standards.

2. Fully enclosed protective cabin + explosion-proof observation window, ensuring the safety of test personnel.

Energy-efficient and high-performance: Energy feedback technology recovers 30% of the energy during testing, standby power consumption < 200W.

Equipment Advantages

High efficiency and accuracy:

1. Dual-station synchronous testing, efficiency increased by 100%, 72-hour aging equivalent to 3 months of actual use.
