How does ETC get power?

[PaisleyFitz]

There are two power supply modes for the ETC in the car: one is using a solar panel for charging, and the other is using wired charging. Both types of ETC electronic tags have internal batteries. Solar-powered ETC devices do not require charging during daily driving, and the lithium battery can last for 3 years under normal use. However, for those who do not frequently use ETC, it is recommended to charge the ETC device every 3 months to effectively reduce the impact of natural discharge on the battery's lifespan. For solar-powered ETC devices, you can park the car under the sun for a few hours to charge the device. ETC is the abbreviation for Electronic Toll Collection, meaning electronic toll 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 it is not the owner applying, 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, you will need a bank card for deducting highway tolls, be between 18 and 60 years old, and own the vehicle in your name. 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 at the toll station. Using computer networking technology, it settles accounts 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: Save time: Avoid the hassle of waiting in line; Green and environmentally friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Reduce wear and tear: Save costs by reducing the frequency of vehicle starts and stops, minimizing wear and fuel consumption, and users can enjoy toll discounts; Improve efficiency: ETC lanes can theoretically improve traffic efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
