What does the range under NEDC specifications mean?

NEDC stands for New European Driving Cycle, which translates to the New European Driving Cycle in Chinese. It is Europe's range testing standard. In China, the Ministry of Industry and Information Technology uses the NEDC testing standard when measuring the comprehensive range of pure electric vehicles. During NEDC testing, the vehicle is placed on a dynamometer. Although it can also be conducted on a windless flat road, to simulate various conditions encountered during actual driving, the rollers in contact with the tires are equipped with motors to simulate resistance under different operating conditions. The test includes two operating conditions: the first is the urban driving cycle, which simulates city driving from 0 to 780 seconds, involving acceleration, maintaining speed, deceleration, and stopping, repeated four times. Starting from the 780th second, the second operating condition, the suburban driving cycle, is tested. In the suburban cycle, the vehicle speed is significantly faster than in the urban cycle. Tips for extending the range of pure electric vehicles: 1. Control the charging rhythm: While driving, if the battery indicator lights up yellow or red, it indicates the need to charge. If only the red light remains on, you must stop using the vehicle and charge it as soon as possible. Otherwise, excessive battery discharge will severely shorten its lifespan. If the driving time is not very long, the owner should control the charging time to avoid prolonged charging. 2. Avoid aggressive driving: Electric vehicles consume more power during aggressive driving. It is important to control the speed and drive smoothly when operating an electric vehicle.

Why does the car remote control work intermittently?

There are several reasons why a car remote control may work intermittently: 1. Low battery in the key. After 2 years of vehicle use, the battery in the key may be depleted, preventing the vehicle from receiving signals from the key. During inspection, first observe whether the key's indicator light is functioning normally. If it doesn't light up or is noticeably dim, check the key battery. If the battery is confirmed to be dead, simply replace it; 2. External interference, such as near high-voltage power lines or airports. The signal frequency from the key may be disrupted or scrambled. Typically, moving away from such locations can resolve the issue without the need for repairs; 3. Damage to the key itself. In this case, check that the key battery is normal and there is no external signal interference. Try using another key. If the issue is resolved, it indicates the key itself is damaged; 4. If all keys exhibit the same problem, it may indicate an issue with the vehicle's electrical system, such as a damaged control unit in the anti-theft system or wiring problems. In such cases, the vehicle should be taken to a repair facility for further diagnosis and measurement using diagnostic tools and professional equipment to determine the exact cause of the fault.

How is a panel defined for car painting?

In car painting maintenance, each door is counted as one panel, while the hood, trunk lid, and roof each count as one panel respectively. The front and rear bumpers are each considered one panel, and the left/right front fenders and left/right rear fenders together make up four panels. Below are specific details about car painting maintenance: 1. The most common car painting maintenance is polishing and waxing. Polishing removes the oxidized layer on the paint surface, making the car noticeably brighter. After waxing the car body, water droplet adhesion can be reduced by 50% to 90%, protecting the paint while also helping to prevent dust and high temperatures. 2. New cars do not require polishing. The surface of a new car does not oxidize immediately, and polishing may damage the paint, having the opposite effect. For new car maintenance, simply wash the car thoroughly and apply wax directly without polishing. 3. The durability of spray painting and waxing is relatively short, typically lasting about 2 months. For cars over one year old with severe oxidation or obvious scratches, it is recommended to polish first before spray painting and waxing to remove the oxidized film on the car body and maintain the paint's luster.

Which city does Ji F belong to?

Ji F is the license plate number for Baishan City in Jilin Province. Here are the specific details about car license plates: 1. The first character of a car license plate is a Chinese character representing the provincial-level administrative region where the vehicle is registered, which is the abbreviation of the province, municipality, or autonomous region. 2. The license plate is a lifelong system, and once a car is registered with a license plate, the plate cannot be changed. Unless the car is transferred to a new owner, a new license plate can be issued, which then belongs to the new owner. The only way to change a license plate number is to transfer the vehicle, either by transferring the old plate number to someone else or canceling it, and then applying for a new license plate number. 3. Generally, a license plate must be registered within 15 to 30 days after purchase, so changing a license plate number must be done promptly, as it will expire and become invalid after the deadline.

What Causes the Suction Sound When Opening the Fuel Tank?

Here are the specific reasons for the suction sound in the fuel tank: 1. Malfunction of the carbon canister or solenoid valve. The pressure inside the fuel tank is lower than the external pressure, which can cause the tank to deform. Severe deformation may prevent refueling. 2. When the pressure inside the fuel tank is lower than the external pressure and there is no ventilation with the outside, the fuel pump will draw outward. Over time, this may lead to damage to the fuel pump. 3. Continuous evaporation of fuel in the tank increases internal pressure. To mitigate the effects of vapor and prevent these fuel vapors from directly polluting the atmosphere, a pathway is designed between the car's fuel tank and the engine intake manifold.

How to Check if a New Car Meets China 6 Emission Standards?

Here are the methods to check if a new car meets China 6 emission standards: 1. Visit relevant query websites such as the Motor Vehicle Environmental Protection Website, and directly enter the vehicle identification number (VIN) and engine number to check. 2. Vehicle Certificate of Conformity: Many products come with a certificate of conformity, and cars, being such significant purchases, are no exception. The vehicle certificate of conformity will clearly indicate the emission standard of the car. Additionally, the certificate is usually collected and archived by the vehicle management office during registration, so it's advisable to take a photo or make a copy before registration for future reference. 3. Environmental Information List: This document directly states the vehicle's exhaust emission standard, whether it's China 5 or China 6. By reviewing this list, you can clearly determine if the car meets the China 6 standard. 4. Vehicle Conformity Certificate: When purchasing a car, you can request relevant documents and certificates from the salesperson. Although the Vehicle Conformity Certificate does not directly state whether it's China 5 or China 6, the information "GB18352.5-2013" can indicate that the vehicle's exhaust emission belongs to the fifth stage, meaning it's a China 5 vehicle. 5. Check the VIN directly: The VIN can be seen in the corner of the front windshield. The tenth letter of the VIN represents the production year of the vehicle, with A standing for 2010, and so on (excluding the letter I), J for 2018, and K for 2019. If the tenth digit of your new car's VIN is J, it means the car was produced in 2018, an "older" model, and you can question whether it truly meets the China 6 emission standard. Of course, the production year does not directly represent the vehicle's emission standard, so this method is for reference only.
