What are the methods for current limiting tests of electric vehicle controllers

Introduction: As a core component of the power system, the current-limiting function of the electric vehicle controller directly affects the safety, energy efficiency, and lifespan of the entire vehicle. The current-limiting design aims to prevent damage to the motor, battery, or controller due to overcurrent. Therefore, strict current-limiting tests are a crucial step in the research and development and production processes. This article will systematically introduce the common methods of current-limiting tests for electric vehicle controllers and their application scenarios.

48v electric vehicle controller output motor is alternating current?

The output motor of the 48V electric vehicle controller is direct current. The working principle of the controller is to chop the direct current so that the peak voltage is almost equal to the battery voltage, and the interval between the waves becomes the key. By adjusting the interval between the waves, the average voltage of the output can be changed, thereby changing the output power.

What are the common faults of electric vehicle controllers and how to repair them?

The controller of an electric vehicle is one of the four important parts of an electric vehicle. It is the "brain" of the electric vehicle. It controls the start, operation, advance and retreat, speed, and stop of the electric vehicle motor. If the controller has a problem, it will be difficult to move. So the "health" of the controller is very important! At ordinary times, riding should be cherished well, so that it can work better for you!

If the controller is broken, the following symptoms will occur.

Stop-and-go, the rear wheel does not rotate or it is difficult to push up, the noise is loud, the load is slow, the start is slow or weak, the electric vehicle vibrates, the motor does not rotate, the power consumption is higher than usual, and the speed is fast and slow.
