Why doesn't the electric car move after braking and applying power?

Here are the reasons why an electric car doesn't move after braking and applying power: 1. Damaged electronic components: The Hall sensor inside the accelerator (throttle) is damaged. The accelerator is crucial for electric cars, and the Hall sensor is vital for the accelerator, so damage to the Hall sensor will directly cause the vehicle to have no response when pressing the throttle even if there is power. To check if the Hall sensor is damaged, you can examine its rated voltage and current to see if they are within the specified range. Values above or below this range will cause the Hall sensor to malfunction. 2. Brake system failure: The brake power-off system is stuck or not reset, causing the brake system to remain engaged. In this case, the throttle may show "no response." Alternatively, there might be a broken control circuit or a faulty controller. The controller starts working after receiving the signal from the throttle. If the controller is short-circuited or faulty, the throttle naturally won't respond. 3. Motor failure: A motor failure will directly prevent the vehicle from operating, making the throttle useless. Identifying a motor failure is simple, as it is usually accompanied by smoke, sparks, or excessive temperature. Observing any of these signs indicates a motor failure. In such cases, it's necessary to visit a repair shop for maintenance.

I've experienced several instances where my electric car wouldn't move when given power. The most common reasons are insufficient charge in the high-voltage battery or rapid discharge, causing the vehicle to enter protection mode and refuse to accelerate. Another possibility could be an issue with the drive motor controller, where the brake isn't fully releasing; when sensors detect that the brake signal is still active, the system will prevent power output. Software glitches might also trigger this, such as bugs appearing after system updates that limit acceleration response.

My suggestion is to first check the battery indicator for remaining charge - if it's too low, try charging immediately. Simultaneously, gently press the accelerator to see if any error codes appear on the dashboard. If restarting the car (turning off the power for 30 seconds before restarting) solves the issue, it's likely a temporary problem. Otherwise, you'll need to visit a professional repair shop to inspect the high-voltage system's safety.

For long-term prevention, regularly maintain battery health and avoid frequent sudden braking.

I found that when the electric car doesn't move after braking, start with the simple things. Check if the brake pedal is stuck or hasn't rebounded; sometimes dust clogging the sensor can falsely report the brake status. Try switching to park and then back to drive to reset the system. Also, pay attention to the battery status: low charge or excessive temperature can trigger protection mechanisms. I remind everyone not to repeatedly test the accelerator, as it can easily burn out the controller. Safety first—test in an open area or pull over with hazard lights on and wait for assistance. Daily prevention includes checking battery stability after charging and cleaning brake system components monthly to reduce such failures.

To address the issue of acceleration failure after braking in an electric vehicle, I would troubleshoot step by step. First, ensure the vehicle is ready with no warning lights on the dashboard. Check if the brake is fully released; if not, gently push the pedal manually. Try shifting gears (e.g., from drive to neutral). Inspect the battery level display and recharge if insufficient. Perform a reset: turn off the main power for one minute and restart. If the problem persists, it might indicate a control module malfunction. Avoid damp environments or aftermarket parts to prevent short circuits. Stop the vehicle immediately for safety and address the issue without delay.
