Electric Scooter Unicycle Test Bench DR-DL106

This equipment is mainly used for testing electric motorcycles and unicycles. It mainly uses servo motors to drive the rollers to rotate and provide load force to simulate road conditions. It can perform tests such as "maximum speed test", "road driving test", "acceleration performance test", "chassis dynamometer driving test", "constant speed climbing test", "constant slope climbing test", "100 km acceleration test", "maximum speed test", "range test", and "100 km power consumption test" on electric motorcycles and unicycles. The vehicle is fixed on the fixture, and the equipment supplies power to the vehicle's motor. The start-up of the vehicle is set, and during operation, the load motor provides a programmable load torque to the wheels. The load torque, speed, voltage, and current of the vehicle during operation are detected, and the load power and input power of the power supply are calculated and plotted on a curve. All test data are recorded and support the generation of reports and export.

Main technical parameters

Core Technology Highlights and Functional Design

✅ Servo Drum Load Simulation: Laboratory-level Reproduction of Real Road Conditions

The equipment uses high-precision servo motors to drive the drum (torque accuracy ±0.5N·m, speed accuracy ±1rpm), simulating the resistance under different road conditions through "programmable load torque settings", covering the full range of scenarios from "light-load commuting" to "heavy-load climbing" for electric motorcycles and unicycles:

✦ Adjustable Load Torque:

The load motor provides programmable torque from 0 to 500N·m (electric motorcycle mode: 100 to 500N·m; unicycle mode: 0 to 100N·m), supporting scene settings such as "flat road resistance (50N·m)", "slope resistance (200N·m)", and "low resistance on wet and slippery roads (30N·m)";

The torque output curve can be customized (sine wave/square wave/random wave) to simulate dynamic resistance changes such as "continuous bumps" and "emergency braking impact" (traditional road tests cannot control resistance fluctuations, with data deviation > 25%).

✦ Drum Speed Control:

The drum speed range is 0 to 120km/h (electric motorcycle) / 0 to 30km/h (unicycle), with an accuracy of ±1rpm, capable of simulating scenarios such as "city speed limit (50km/h)", "high-speed cruising (80km/h)", and "unicycle regular commuting (15km/h)";

Supports "acceleration/deceleration slope" settings (e.g., 0 to 50km/h acceleration time of 3 seconds), accurately reproducing instantaneous actions such as "starting from a red light" and "overtaking acceleration" (traditional equipment only supports constant speed testing). 

✅ Full-Chain Data Collection and Analysis: From Power to Energy Consumption, Covering 10+ Core Parameters

Equipment Integration: A multi-sensor data collection system (sampling frequency 100Hz) is integrated to synchronously monitor 12 core parameters including "load torque, wheel speed, motor voltage/current, battery SOC (state of charge), and temperature", and calculate in real time "load power (P = torque × speed / 9550)", "input power (P = voltage × current)", and "efficiency (load power / input power)", generating dynamic curves (such as "time-power" and "speed-energy consumption"):

✦ Key Parameter Monitoring:

Maximum speed test: Record the "linear speed of the roller corresponding to the maximum motor speed" (error ≤ 0.5 km/h) to verify compliance with the "new national standard for electric motorcycles ≤ 50 km/h" and "EN standard for unicycles ≤ 20 km/h".

Range and energy consumption test: Set a "city driving cycle" (acceleration - cruising - deceleration), record "battery discharge depth (DOD)", "cumulative mileage", and "energy consumption per 100 km (Wh/km)", with an error ≤ 2% (traditional road tests are affected by driving habits, with an error > 10%).

Climbing performance test: At a fixed slope (e.g., 5°/10°) or a fixed speed (e.g., 20 km/h), monitor "motor output torque", "battery voltage drop", and "motor temperature rise", to verify "constant speed climbing" (minimum torque required to maintain speed) and "constant slope climbing" (maximum climbable slope) performance.

✦ Abnormal Warning and Protection:

When the motor temperature exceeds 80°C (for electric motorcycles) / 60°C (for unicycles), trigger "power reduction protection" (output torque reduced by 50%).

When the battery voltage drops below the under-voltage threshold (e.g., 36V), automatically cut off power supply and mark "battery depletion".

When the load torque exceeds the set value by 110%, unload within 0.1 seconds to prevent motor stalling or transmission system damage (traditional equipment has no protection mechanism, with a component failure rate > 8%). 

✅ Intelligent Control and Data Management: From parameter setting to report output, the entire process is fully automated.

✦ Multi-mode Programmed Control:

Equipped with dedicated test software (compatible with Windows/Linux dual systems), it features built-in "Electric Scooter Test Template", "Unicycle Test Template", and "Custom Mode", supporting multi-stage continuous testing such as "Top Speed → Acceleration Performance → Range" (one-click invocation, no manual switching required);

Supports "Cyclic Testing" (e.g., repeating 5 times of 100km/h acceleration), verifying "Performance after Thermal Degradation" (traditional equipment requires manual restart, increasing the time by 3 times).

✦ Full-cycle Data Storage and Traceability:

Equipped with a 1TB industrial-grade hard drive, it can store 10,000 sets of complete test records (including original curves, alarm logs, and test conclusions), and supports quick retrieval by "vehicle model/test item/time";

Automatically generates PDF/Excel/CSV reports (including key parameter comparison tables, trend analysis graphs, and compliance determinations), and directly links test results to standard requirements such as "New National Standard" and "EN 17128" (e.g., marking "Top Speed 48km/h (compliant with GB 17761 ≤ 50km/h)"). 

Application Scenarios and Customer Value

1. Full Inspection on Production Lines: Dual Improvement in Efficiency and Yield Rate

✦ Adaptability to Production Lines:

Seamlessly integrated with the "assembly - debugging - testing" process of electric motorcycle and unicycle assembly lines, with a daily testing capacity of 15-20 units for electric motorcycles and 30-50 units for unicycles, meeting the needs of medium and small batch production lines with a monthly output of 500 electric motorcycles and 1,500 unicycles;

The qualified rate of finished products has increased from 85% (random road tests) to 99%, saving an annual repair cost of 500,000 yuan (based on an annual output of 6,000 electric motorcycles and 18,000 unicycles).

2. Performance Optimization in R&D: Accelerating Product Iteration

✦ Comparative Testing of Multiple Schemes:

Simultaneous testing of electric motorcycles with different configurations (such as lead-acid batteries / lithium batteries) and unicycles with different motors (such as brushless motors / brushed motors);

Output "configuration - performance" correlation reports (such as "lithium batteries have a 40% longer range than lead-acid batteries, but their performance degrades 20% faster at low temperatures"), assisting R&D teams in quickly identifying the optimal solution (traditionally requiring 3-6 months of road tests, reducing the time by 80%).

3. Third-Party Testing: The "Golden Certificate" for Authoritative Certification

✦ Compliance Support:

The equipment is certified by the CNAS laboratory (China National Accreditation Service for Conformity Assessment), and the test reports comply with international standards such as GB 17761, EN 17128, and UL 2272;

The test reports include original data curves and comparison tables with standard parameters, which can be directly used for export certifications of electric motorcycles and unicycles (such as EU CE and US FCC).
