Should I repaint the scratches on my new car door?

The decision to repaint depends on the severity of the scratches. Here are specific recommendations regarding repainting: 1. Minor damage: It's unavoidable that some hard objects may scratch the car paint during daily use. For such minor damage, besides passive acceptance, you can take preventive measures. Applying wax every 1-2 months or installing wear-resistant patches on frequently affected areas can help prevent minor scratches to some extent. 2. Light damage: In most cases, the scratches on the paint surface are clearly visible. For this situation, it's recommended to use a touch-up pen for treatment. 3. Moderate damage: When the paint shows obvious peeling, exposing the primer, immediate action is necessary. Repainting should be done as soon as possible to prevent the exposed steel plate from rusting due to rain or other factors.

How Many Kilometers Can an Electric Vehicle Travel on 1 kWh of Electricity?

Under normal circumstances, 1 kWh of electricity can power a vehicle for approximately 7 kilometers. However, this figure is heavily influenced by the vehicle's curb weight and road conditions, making it less significant as a reference. Below are specific factors affecting the driving range: 1. Comprehensive Factors: The increase in an electric vehicle's range is the result of multiple factors. To enhance its driving range, the key lies in battery technology—continuously improving battery performance—while also considering factors such as vehicle size and price. 2. Other Factors: The overall driving range can be affected by various other elements, including battery performance in high and low temperatures, optimization of battery BMS technology, upgrades to the vehicle's energy recovery system, lightweight body design, and energy-saving technologies in hardware. External driving conditions, air resistance coefficient, mechanical transmission efficiency, vehicle weight, and the number of passengers can all impact the actual driving range of an electric vehicle.

What Does Insulation Fault in New Energy Vehicles Mean?

Insulation fault in new energy vehicles refers to a leakage in the electrical circuit. The following is a detailed introduction to insulation faults in electric vehicles: 1. Cause: Insulation faults occur when the electrolyte inside the battery leaks, leading to liquid seepage. When the liquid seeps to a certain extent, the insulation layer is compromised, creating a conductive circuit between the battery modules and cells, which triggers the fault warning. If there is only a single point of insulation failure in the system, it may not immediately cause noticeable effects. However, multiple points of insulation failure can result in leakage current flowing between these points, potentially leading to a fire. 2. Precautions: Operators must wear protective equipment that meets national safety standards, such as insulated gloves and insulated shoes. In the event of an insulation fault, the faulty battery pack usually needs to be replaced. If multiple insulation faults occur, the entire battery may need to be replaced.

What Causes the Creaking Sound When Slowly Releasing the Brake in an Automatic Transmission Car?

Automatic transmission cars often produce a creaking sound when the brake is released too slowly during startup. This is a common issue with many automatic vehicles. Here is some related information about car brakes: 1. Brake Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, and other transportation tools or machinery. 2. Working Principle: The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. The brake device is a mechanical braking device that can slow down the speed of the vehicle, also known as a decelerator.

What Stickers Are Still Required on the Car Windshield Now?

Currently, the car windshield still needs to display the annual inspection sticker and the auto insurance sticker. Below is an introduction to the stickers required on the car windshield: Annual Inspection Sticker on the Windshield: At present, the windshield only requires the annual inspection sticker. The latest policy states that the vehicle annual inspection and the environmental protection inspection sticker have been combined into one, with the vehicle emissions test continuing as usual. As long as the annual inspection is passed, there is no need to obtain a separate environmental protection sticker. In 2019, the compulsory traffic insurance sticker was no longer required to be displayed by drivers. Now, the annual inspection stickers are all connected to the traffic police system and are electronic stickers that can be checked, eliminating the need to display them on the windshield. Auto Insurance Sticker on the Windshield: The windshield needs to display the vehicle inspection sticker. The vehicle inspection sticker, compulsory traffic insurance sticker, and environmental protection inspection sticker were once indispensable and had to be neatly displayed on the windshield. However, after the new regulations were introduced, the environmental protection inspection sticker was abolished, leaving only the vehicle inspection sticker and the compulsory traffic insurance sticker. The auto insurance sticker is one of the important indicators to determine whether a vehicle has compulsory traffic insurance. It bears the words "Supervised by the China Insurance Regulatory Commission." The insurance policy is brown in color, with the text printed using internationally advanced red fluorescent anti-counterfeiting ink. The lower horizontal line of the text is composed of microtext, providing excellent anti-counterfeiting features. Except for the area reserved for printing the company logo by different insurance companies, the specifications and style of the insurance policy are uniform nationwide. The auto insurance sticker on the vehicle windshield serves as proof that the vehicle has participated in the compulsory third-party liability insurance for motor vehicles. As evidence of insurance, traffic police can verify whether the insurance is active and valid.
