Does the car ETC need to be charged?

Installing an ETC does not require charging, as the ETC uses its own built-in power source. The ETC electronic tag consumes power, but there is no need to charge the battery during normal use because the back of the battery has a solar panel that can charge itself. During installation, it is necessary to avoid the black areas on the windshield. The built-in power source of the ETC typically has a lifespan of 3-5 years. ETC stands for Electronic Toll Collection, which means an electronic toll system. To apply for an ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is made by someone other than the owner, the agent's valid ID card must also be provided. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway toll fees is required. The applicant must be between 18 and 60 years old, and the vehicle must be registered under a personal name. For a company vehicle, the required documents are: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the original ID card of the agent; the original vehicle registration certificate; and the vehicle for which the ETC is to be installed. The working principle of ETC: Through the on-board electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane of the toll station. Using computer networking technology, it settles accounts with the bank in the background, allowing the vehicle to pay highway or bridge tolls without stopping when passing through toll stations. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Cost-saving: Reduces vehicle start-up and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Improved efficiency: The ETC lane theoretically increases passing efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

As a daily commuter who drives to work, I never thought about charging after installing the ETC. The small device has a solar panel and can power itself either by parking in the sun or drawing power from the car while driving. I've been using it for almost three years, and it opens instantly at highway toll booths, saving both time and effort. Normally, it doesn’t need charging, as the battery is designed for a long lifespan. If the device light goes out, it might need replacement, but the probability of that happening is zero in my experience. I suggest new users not overthink it—just keep it clean. ETC is truly convenient; once installed, you can practically forget it exists.

As an enthusiast with some research on automotive gadgets, I'd like to mention that ETC doesn't require manual charging. Its OBU device comes with a built-in rechargeable battery that draws power from the cigarette lighter or vehicle battery while driving, supplemented by solar energy when parked. The user interface has no charging port, designed to be maintenance-free. Low power consumption ensures the battery lasts for years; if it truly runs out, the device indicator will dim affecting usage, but that's not our concern. ETC is fundamentally a wireless communication toll system, where charging doesn't impact functionality. After installation, forget about it and enjoy the benefits of fast passage.

As a new driver, I installed an ETC right away and was initially worried about whether it needed charging. My colleague told me not to worry—the device automatically charges from the car's power supply and can also sustain power with sunlight. After a week of driving, passing through toll stations became incredibly fast, with automatic fee deductions, eliminating the hassle of queuing at manual booths. Everything works fine without maintenance; if the light doesn’t turn on, it might indicate an issue, but that’s rare. Just drive without a second thought.

As a seasoned driver with decades of experience, I've never had to recharge my ETC since installation. The kids explained it self-charges using sunlight or the vehicle's power supply. It's been worry-free for highway use over the years—efficient with no traffic jams. If it ever breaks down, I'll deal with it then.
