I faced sudden power losses on my Bajaj Chetak EV in the past. The main thing of trouble was that it happened during the way and in high traffic zones.
Out of curiosity, I wanted to know the reasons. I went to the service centre during a weekly off day to understand the potential issues regarding this problem and an effective solution.
I talked to the company expert in this area at length, and he gave me certain reasons and also demonstrated them practically. It was satisfactory.
In this blog, I will try to highlight the reasons he told and the effective solutions.
Some of the common reasons for the sudden power loss in the Bajaj Chetak electric scooter and how to fix them are mentioned below.
Battery Issues
If the battery is not properly charged or has degraded over time, it can cause sudden power loss.
It is human nature when it comes to batteries for EVs. We do not charge as per guidance.
I am aware now because I faced a sudden power loss because of this at a traffic signal.
Thank God, I was able to keep the scooter by the side.
Also, if you’re a heavy rider or use high power to drive the scooter, that can drain the battery much faster compared to normal driving mode.
What do you think? What is the right solution for it?
The simple solution to this problem, make sure the battery is fully charged before each ride. If not fully, you can charge it up to 80%.
Try to ride your scooter smoothly to save power, which will ultimately increase your Bajaj Chetak’s driving range.
Thermal Shutoff
Thermal shutoff is a feature in EVs that automatically cuts off power when the motor overheats.
If you have a faulty or damaged battery that overheats your Bajaj Chetak EV, it can cause a sudden loss of power while driving.
If this is the cause, you need to have the battery replaced or repaired by a service technician.
Based on my own experience, avoid overloading the scooter or riding in high temperatures to prevent motor overheating.
Faulty Wiring or Connectors
Loose, damaged, or corroded wiring and connectors can disrupt the battery’s power supply.
Have the wiring inspected and any related problems repaired by an authorized service center, or you can do it yourself if you have the proper knowledge.
Avoid riding through water or washing the scooter with high pressure to prevent water damage to the connectors.
Throttle Sensor Problems
The throttle position sensor (TPS) tells the motor controller how much power to deliver based on how far you twist the throttle.
If the TPS sends wrong signals, the controller might think you want more power than you do. This can cause sudden acceleration or unexpected power loss while riding.
This sensor is located in the handlebar assembly of the Bajaj Chetak EV.
How to Fix it?👇
- Clean the Sensor: Ensure good electrical connections by cleaning the sensor.
- Test the Sensor: Use a multimeter to check if the sensor is outputting the correct voltage signal as you twist the throttle.
- Replace the Sensor: If the sensor is faulty, replace it.
Controller Issues
The motor controller regulates the power to the motor. Faults in the controller can lead to sudden power loss.
Inspect the controller and do the necessary repairs through an authorised service centre if faulty.
Avoid overloading the scooter or riding in high temperatures to prevent controller overheating.
I used to carry heavy weight on my Bajaj Chetak EV in the past but after the sudden power loss due to this factor, I got a suggestion at the service station to avoid carrying extra weight more than the specified limit.
Mechanical Faults
Mechanical issues like seized wheel bearings or faulty brakes can also cause sudden power cuts.
Make sure you inspect the Bajaj Chetak EV for any mechanical faults by a service technician.
Ensure the brakes are working properly and the wheels spin freely.
Regular maintenance, using genuine parts, and avoiding overloading the Bajaj Chetak EV scooter can help prevent sudden power loss.
If problems persist, inspect the Bajaj Chetak EV at an authorised service station.
Final Thoughts
You should be aware of the above guidelines if the problem persists. You can easily handle the problem.
Sudden power loss could be a cause of high concern because this is not a minor issue. There is high risk of a major crash if it happens in high-power zones.
If you have faced this issue, focus on the above-mentioned causes and see the exact reason. By the end of the day, Bajaj Chetak EV should not raise this issue further.
If you rectify the above-mentioned causes on a timely basis, this problem will not arise. If it still happens, your EV always provides you with the desired technical support from experts.
