Does ETC need to be connected to a power source?
2 Answers
Installing ETC does not require an external power connection as it uses its own built-in power source. The ETC electronic tag consumes power, but it does not need to be charged during normal use because there is a solar panel on the back of the battery that can charge it automatically. During installation, it is necessary to avoid the black areas on the windshield. The built-in power source of ETC typically has a lifespan of 3-5 years. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for 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 not made by the owner, the agent's valid ID card is also required. 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 tolls is needed. Applicants must be between 18 and 60 years old, and the vehicle must be registered under an individual's name. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; and the vehicle that needs to be equipped with ETC. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, it settles the toll with the bank in the background, allowing the vehicle to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Avoid the hassle of waiting in line; Green and eco-friendly: Low-carbon solution, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions; Cost-saving: Reduces vehicle start-up and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Efficiency improvement: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
When I installed the ETC device in my car before, I was also worried about wiring issues, but it turned out to be unnecessary! The ETC device comes with a small solar panel and can automatically charge when installed on the front windshield. I specifically observed that when the car was parked in an open parking lot, that little black block was quietly absorbing sunlight. Of course, if the car is parked in a basement for several weeks in a row or has a metal explosion-proof film that blocks the light, the battery might run out. But such cases are rare, and most people's ETC devices can last for years without any attention. If it really runs out of power, don’t panic—just drive it out into the sun for two hours, and it will come back to life. It’s much more hassle-free than the old devices that had to be plugged into the cigarette lighter.
