Does ETC installation require connection to the car's power supply?

[FernandoMarie]

Installing ETC does not require an additional power connection, as ETC 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 the battery has a solar panel on the back that allows it to charge itself. During installation, it is important 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, which refers to the electronic toll system. To apply for ETC, the vehicle owner must provide valid identification and the original and photocopy of the vehicle registration certificate. If the application is made by a proxy, the proxy's valid identification 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 toll fees is required, and the applicant must be between 18 and 60 years old, with the vehicle registered under their name. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles transactions with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay tolls. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions, as vehicles pass through toll stations without stopping. Cost-saving: Reduces wear and tear and fuel consumption by minimizing vehicle starts and stops, and users can enjoy toll discounts. Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC more advanced, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
