FCT Test Equipment for Automotive Motor Control Board

The electrical testing of an electric vehicle controller is a complex but crucial process aimed at ensuring its functionality and reliability. Here are some key steps in conducting electrical tests:

Visual Inspection:

• Before starting the electrical tests, perform a visual inspection to ensure the controller has no apparent physical damage or defects.

Connection Test:

• Use a multimeter or specialized testing equipment to check all the electrical connections of the controller, including power lines, ground lines, signal lines, etc., to ensure they are secure and free from short circuits or open circuits.

Power Test:

• Power up the controller and use a voltmeter or oscilloscope to check if the power supply voltage is stable and meets the specifications.
• Observe the behavior of the controller during power-on and power-off processes to ensure there are no abnormal phenomena.

Functional Test:

• According to the technical specifications and functional requirements of the controller, write test programs or use automated testing software to simulate various working conditions and scenarios.
• Check the performance of the controller under different loads, speeds, temperatures, and other conditions.
• Verify that all functions of the controller are normal, such as acceleration, deceleration, braking, steering, etc.

Signal Test:

• Use equipment like oscilloscopes or logic analyzers to check if the signal waveforms and timing output by the controller meet the requirements.
• Ensure the controller can correctly receive and process signals from sensors, actuators, and other external devices.

Fault Diagnosis and Recording:

• If the controller encounters faults or anomalies during testing, use fault diagnosis tools or software to locate the cause of the problem.
• Record all test results and fault information for subsequent analysis and improvement.

Environmental Adaptability Test:

• Conduct environmental adaptability tests on the controller, including high temperature, low temperature, humidity, vibration, etc., to ensure it works stably under different environments.

Safety Test:

• Check if the controller's protection functions such as overcurrent, overvoltage, undervoltage, etc., are working normally.
• Ensure the controller can safely shut down or take other protective measures in case of abnormal situations.

In summary, the electrical testing of an electric vehicle controller needs to consider multiple aspects, including connections, power supply, functionality, signals, fault diagnosis, environmental adaptability, and safety. Through comprehensive testing, the quality and reliability of the controller can be ensured, enhancing the overall performance and safety of the electric vehicle.
