Does the ETC Reader Need to Be Charged?

[DiJuniper]

There are two types of ETC devices: solar-powered and rechargeable. The solar-powered ETC does not require charging as it uses its own power source. The ETC electronic tag consumes power, but it does not need regular charging because it has a built-in solar panel on the back that charges itself. During installation, avoid the black areas on the windshield. The other type requires charging, and if it is not used frequently, it is recommended to charge it every two to three months. ETC stands for Electronic Toll Collection, which is 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 vehicle registration certificate. If the application is not made by the owner, the agent must also provide their valid ID card. The photocopy of the vehicle registration certificate must include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old and own the vehicle in their name. For company vehicles, the required documents include: A letter of introduction from the vehicle owner (with company seal); a photocopy of the organization code certificate or business license (with company seal); the agent's original ID card; the original vehicle registration certificate; and the vehicle for which ETC is being applied. Benefits of installing ETC: Saves time: Eliminates the hassle of waiting in line. Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping. Reduces wear and tear: Lowers costs by decreasing the frequency of vehicle starts and stops, reducing wear and fuel consumption. Users also enjoy toll discounts. Improves efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster and more advanced. Compared to license plate payment, ETC technology is more mature and advantageous. Here are some installation precautions for ETC: Do not obstruct the driver's view; it is best to install it behind the rearview mirror. Many car models have windshields with a steep angle, which can reduce the driver's field of vision. Installing ETC without considering this can increase blind spots. Install it behind the rearview mirror on the right side to avoid blocking the view. Does not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that charges itself. Therefore, during installation, avoid the black areas on the windshield and positions that might block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. Once the electronic tag is installed on the windshield, the anti-tamper lever is pressed in. If removed, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This feature prevents multiple vehicles from sharing one device.

I've been using an ETC card reader in my car for several years. It's usually installed on the windshield or near the dashboard, directly connected to the car battery for power, just like the headlights or radio, so it doesn't require separate charging. However, if the car battery is aging or has insufficient power, the ETC might temporarily malfunction, causing it to fail recognition at toll stations. Last winter, I experienced this once when the reader's light went out, and it turned out to be a slightly loose battery contact point. Cleaning off the oxidation restored normal function. Usually, I recommend a quick check of the ETC's mounting during annual maintenance to keep it clean and prevent dust from blocking the antenna. Don’t worry about frequent charging like a phone—it activates automatically when the car starts, which is quite hassle-free. For owners who frequently drive short distances, less battery charging might also have an impact, but it's generally not a big issue. Overall, the ETC is designed to be very user-friendly, focusing on driving convenience.
