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.

What is electric vehicle controller?

The electric vehicle controller is an important component of electric vehicles, playing the role of the "brain" of the vehicle and playing a crucial role in the performance of the electric vehicle. Below is a brief introduction to the electric vehicle controller:

How to judge the electric car controller is broken

The performance of a broken electric vehicle controller is often manifested as unable to walk or not walking well, and the direct performance is unable to drive.

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.

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.

How to detect the quality of electric vehicle controller

Put up the rear wheel, the motor is off the ground, there is resistance to pushing the motor, or turn the handle, the motor has a sound and does not rotate smoothly, and there is no problem with the connection line between the controller and the motor, then the controller may be broken and the controller power tube is damaged; Replace the controller directly, if there is still a problem, it means it is not the problem with the controller.
