How is the ETC in the car powered?

[LylaDella]

There are two power supply modes for the ETC in the car, one is using solar panel 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 collection system. To apply for it, you need to provide the original and photocopies of the vehicle owner's valid ID card and driving license. If the application is not made by the owner, the agent's valid ID card must also be provided. The photocopy of the driving license should include the page with the most recent annual inspection stamp; a bank card for deducting highway tolls; the applicant must be between 18 and 60 years old; and the vehicle must be registered under the individual's name. How ETC works: 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 and uses computer networking technology to settle 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 environmentally friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions and pollution; Cost-saving: Reduces costs, decreases the frequency of vehicle starts and stops, reduces wear and fuel consumption, and users can enjoy toll discounts; Improved efficiency: The efficiency of ETC lanes can theoretically be increased by 2-3 times or more, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
