E-bike chassis dynamometer testing machine

Electric bicycles are complex systems involving mechanical, electrical, and control components. Evaluating their performance and compliance with safety and efficiency standards requires precise and repeatable testing that is difficult to achieve in outdoor environments due to varying weather, traffic, and road conditions. An Electric Bicycle Chassis Dynamometer System addresses this need by providing a consistent platform for comprehensive e-bike testing.

Standard

EN 15194:Cycles - Electrically power assisted cycles - EPAC Bicycles

ISO 4210:Cycles - Safety requirements for bicycles

UL 2849:Standard for Electrical Systems for eBikes

Application

Measuring motor efficiency, power output, and torque characteristics of e-bikes.

Evaluating battery range and energy consumption under simulated riding conditions.

Simulating various road loads, inclines, and driving cycles.

Testing electromagnetic compatibility (EMC) by providing a stable environment.

Conducting endurance and durability testing on e-bike components.

Verifying compliance with national and international standards for e-bike performance and safety.

Test Procedures

Preparation: Ensure the dynamometer is in good working order and prepare the necessary tools and equipment for the test. Check that the electric vehicle under test meets the test requirements, such as being fully charged and free of malfunctions.

Connect the power supply: Connect the electric vehicle to the dynamometer and switch on the power. At this point, the dynamometer should be in a "no-load" state.

Set parameters: Set the appropriate parameters according to the test requirements, such as test time and speed range.

Start the test: After confirming that all parameters are set correctly, start the test program. The dynamometer will perform the test according to the set parameters and record the test data.

End the test: After the test is completed, close the test program, disconnect the power supply, and remove the electric vehicle. The test results can then be viewed and data analysis can be performed.
