How is the ETC device powered?

[StLola]

Installing ETC does not require charging, as the ETC device uses its own built-in power source. The ETC electronic tag consumes power, but it does not need regular battery charging during normal use. This is because there is a solar panel on the back of the battery that allows it to 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 ETC, the following documents are required: the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is made by a proxy, the proxy'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 a personal name. For company vehicles, the required documents are: An introduction letter from the vehicle owner (with company seal); a photocopy of the organization code certificate or business license (with company seal); the original ID card of the proxy; the original vehicle registration certificate; and the vehicle for which ETC is to be installed. The working principle of ETC: Through the vehicle-mounted electronic tag installed on the windshield, it communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, it settles transactions with the bank in the background, allowing vehicles 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: Reduces noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-saving: Reduces vehicle startup and braking frequency, minimizing wear and fuel consumption, and users can enjoy toll discounts; Increased efficiency: The ETC lane theoretically improves traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
