What is the lifespan of an ETC battery?

[DiGemma]

Generally, the battery of an ETC device can last for 3 years under normal usage. For solar-powered ETC devices that are not frequently used, it is recommended to charge them every 3 months to prevent natural discharge of the internal battery. The ETC device has an internal battery and is charged externally via solar power, so it does not require regular charging. ETC stands for Electronic Toll Collection, which is an electronic toll collection system. To apply for an ETC device, 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 must also provide their valid ID card. 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 required, and the applicant must be between 18 and 60 years old and own the vehicle. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at toll stations. The system then uses computer networking technology to settle the toll with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: 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. 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 systems more advanced and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

My electric car has been running for almost five years, and the battery degradation is only about 10%. Manufacturers generally claim it can last 8 to 10 years or run 200,000 kilometers without issues. Usually, avoid frequently draining the battery below 10% before charging, and ensure the temperature doesn’t exceed 50°C during charging—especially in summer, as outdoor charging is most damaging to the battery. Slow charging at least once a week helps extend its lifespan; owners who always use fast charging tend to experience faster degradation. Remember to regularly check battery health—many brand apps now allow real-time monitoring of battery status, which is super convenient!

I talked to a mechanic, and he said the lifespan of an electric vehicle's battery mainly depends on usage environment and habits. In northern winters, the cold can easily reduce the range by 30%, and frequent full charges and discharges can cause the battery to retire early. Lithium iron phosphate batteries are generally more durable than ternary lithium batteries, with about a thousand more charge cycles. The lifespan claimed by manufacturers is just for reference; in reality, using it for seven or eight years is quite normal. However, when the battery health of a used electric car drops below 70%, it's basically unsellable. Replacing a new battery costs about 30% of the car's price, so proper maintenance can really save you a lot of money!

EV batteries are actually quite durable. My ride-hailing friend drove 150,000 km in two years with 85% capacity remaining. For average household vehicles covering 20,000 km annually, the battery should last at least 7-8 years. The most critical factor is the cooling system - sustained high-temperature discharging can cause permanent damage. Always park in shade when possible, and avoid fast charging immediately after sun exposure. The new solid-state batteries reportedly double the lifespan, though costs remain prohibitive. Just remember: shallow charging/discharging cycles are best for battery health!

Battery lifespan depends on materials and technology. For example, CATL's 811 NCM lithium-ion battery can still retain 80% capacity after 1,500 cycles. In terms of calendar life, normal usage for about ten years is generally fine, but be aware that LFP batteries have poor low-temperature performance and experience faster power loss in northern winters. Don't believe rumors claiming batteries fail in just three years—modern BMS (Battery Management Systems) are highly intelligent and actively balance cell temperatures. Perform a full charge calibration monthly and avoid storing at low charge levels for extended periods. In the second-hand market, the health report is key—anything above 80% is considered good quality!

As a user who has driven three generations of electric vehicles, I've found that extreme temperatures are the biggest killer of battery degradation. In summer, I always charge in underground parking, and in winter, I preheat the battery remotely by turning on the air conditioning. For daily use, I try to keep the battery level between 20% and 80%, only charging to full for occasional long trips. Nowadays, mainstream models come with liquid-cooled battery packs, and good heat dissipation naturally extends battery life. Battery replacement is indeed expensive, but it's free within the eight-year warranty period, and third-party battery pack prices are dropping after the warranty expires. Remember, gentle driving is the most battery-efficient!
