Installing ETC does not require charging as it uses a built-in power source. The ETC electronic tag consumes power, but there is no need to charge the during normal use because there is a solar panel on the back of the battery that can charge itself. 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, which means an electronic toll system. To apply for ETC, 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, a valid ID card of the agent is also required. The photocopy of the driving license 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. 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 the toll. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; 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 expenses by minimizing the frequency of vehicle starts and stops, thereby decreasing wear and fuel consumption. Users can also enjoy toll discounts; Improved efficiency: The ETC lane can theoretically increase 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.

I've used an ETC device before. This thing is installed on the windshield and can charge itself. There's a small solar panel on its back, so it automatically replenishes power when exposed to sunlight while driving. If parked outdoors during the day, it can also charge. The key is not to cover it with a sunshade. Last time, my friend blocked the ETC with a sunshade, and it completely ran out of power, causing it to malfunction at the highway toll gate. If you notice the ETC is low on , parking it in an open area for a few days usually restores the charge. If it's truly broken, you'll need to take it to the original service point for inspection and replacement—you can't open that sealed box yourself.

Keeping your ETC device charged is easy—just expose it to sunlight. Its design is exceptionally convenient, featuring a built-in miniature solar panel that automatically powers up through light exposure. My own car is parked in an open space year-round, and I've never worried about the running out. Just be careful not to place items like parking cards over the device, blocking sunlight, and remember to clear off snow promptly in winter. If the car remains unused for an extended period, it's advisable to start it periodically and park it in the sun to replenish power. In the rare case of low battery causing ETC malfunction, the simplest solution is to drive to a service point near the highway toll station—testing takes just five minutes.

The ETC device is charged entirely by solar power. You don't need to do anything; it charges automatically while you drive normally. If the device becomes unresponsive, check if the windshield is blocking sunlight. Just remove any obstructions and let it bask in the sun for a few hours, and it should recover. If that doesn't work, visit a bank or highway service point—they have professional equipment to handle it. Never attempt to disassemble the device yourself, as it will become void if opened.

Regular exposure to sunlight is the best way to charge your ETC. My car has been parked in the open ground of my residential area every day, and the hasn't been replaced in three years. Rainy days have little impact, as the stored power is sufficient for half a month. The worst scenario is when someone applies dark window tinting or covers it with a cloth, completely blocking sunlight. It's recommended to clean the dust off the device surface at least every quarter to ensure optimal light absorption. In special cases, you can temporarily activate the device using the car's USB power supply, but it's not suitable for long-term use.

My ETC has been working normally for five years, and the secret is to keep it exposed to sunlight. The solar panel on its back is quite durable and functions well even on rainy days. If you notice the is low, you can deliberately park your car in a sunny spot for two to three days. Never follow online tutorials to disassemble and replace the battery, as it will damage the waterproof seal. Also, don’t press the buttons on the device randomly—some models reset data with a single restart button press. If it really won’t charge, go to the original service point for inspection; chances are you’ll need a new device.
