Can the Electronic Parking Brake Be Used After the Vehicle Is Turned Off?

After the vehicle is turned off, the electronic parking brake can be used, and it must be engaged. Below is relevant information about the electronic parking brake: How the Electronic Parking Brake Works: The electronic parking brake is a technology that achieves parking braking through electronic control. Both the electronic parking brake and traditional mechanical handbrakes use the friction between the brake disc and brake pads to control parking braking. The only difference is that the control method changes from a mechanical handbrake lever to an electronic button. Introduction to the Electronic Parking Brake: The electronic parking brake is the Electronic Parking Brake System (EPB). The Electronic Parking Brake System integrates the temporary braking function during driving with the long-term parking braking function after stopping, and it achieves parking braking through electronic control technology.
The electronic parking brake usually remains functional after the vehicle is turned off, as it is powered by the car's battery. After parking and turning off the engine, the battery maintains current for a period, allowing normal operation of the parking brake button. My car is an automatic, and after each shutdown, I manually press the button to activate the parking brake to ensure it doesn't roll on sloped parking areas. If the battery is in good condition, this process is smooth. However, be aware that it may fail if the battery is aging or has insufficient charge, so regular battery health checks are recommended. For safety, developing this habit is always good to avoid unexpected incidents.
From my experience, the electronic parking brake can indeed be used after the engine is turned off. As a commuter who drives to work, I always test the button after parking and turning off the engine, and every time I hear a slight click, indicating the parking brake is engaged. The car's battery power supply system ensures the function remains operational. It's more convenient than a manual handbrake when parking on roadside slopes. If it occasionally doesn't respond, it might be because the key isn't completely turned off or the battery needs charging. I pay attention to the warning light status, and with proper maintenance, there won't be any issues.
