What License is Required for Electric Vehicles?

Electric vehicles require either a C1 or C2 level driver's license, as the driving requirements for electric vehicles are similar to those for traditional fuel-powered vehicles. Currently, pure electric vehicles come in various types such as electric cars, electric trucks, and electric buses, with electric cars being the most common in daily life. Regardless of the vehicle type, drivers must adhere to relevant road safety regulations. Operating a motor vehicle requires certain driving skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Generally, individuals cannot drive on public roads without a license. For vehicle owners who have already mastered safe driving techniques, the required document to drive on roads is a driver's license, which serves as a permit. The authorization to drive a vehicle is granted through the issuance of a driver's license, indicating that obtaining a driver's license is a formal procedure that must be conducted by a specialized authority.

What does the OBD in a car mean?

OBD in a car stands for On-Board Diagnostics, which is primarily used to monitor the operating status of the engine and the exhaust treatment system in real-time. OBD monitors various systems and components in real-time, including EGR, the engine, particulate filters, catalytic converters, oxygen sensors, emission control systems, fuel systems, and more. Its working principle is as follows: when an emission fault occurs, the ECU records the fault information and related codes, and alerts the driver by illuminating the malfunction indicator lamp (MIL) or check engine warning light. Mechanics can then read the fault codes using the vehicle's original specialized equipment to quickly locate the issue, facilitating vehicle repairs and reducing the time required for manual diagnosis.

What are the symptoms of a bad wheel bearing?

If a wheel bearing is damaged, there will be significant noise while driving, and it will generate excessive heat, becoming hot to the touch. The reasons include: 1. Improper assembly or adjustment—all bearing products have specified clearance requirements, but excessive tightness is often overlooked; 2. Poor lubrication—if only a thin layer of grease is manually applied to the bearing surface, dry friction between the rollers and raceway may occur after 3,000 to 5,000 km of driving, leading to bearing seizure; 3. Quality issues with the bearing itself—bearings are complex assemblies, and their lifespan is affected by factors such as material selection for components, heat treatment specifications, precision in cold processing, assembly adjustments, etc. While a shorter lifespan for a small number of bearings is understandable, some manufacturers fail to meet technical standards due to poor management, resulting in substandard products being released.

Do Shock Absorbers Need to Be Replaced Together with Springs?

Shock absorbers do not need to be replaced together with springs. Replacing shock absorbers does not necessarily mean replacing the springs, as they are two different components. Therefore, when there is an issue with the shock absorbers, the springs do not need to be replaced at the same time. Additionally, springs are essentially maintenance-free for the lifetime of the vehicle, whereas shock absorbers are wear-and-tear items that typically require replacement every 100,000 kilometers or less. Springs should be replaced under the following circumstances: 1. If visible cracks are found on the springs, they should be replaced promptly. During driving, it is difficult to predict what might happen to the shock absorbers, and if hard objects get lodged in them, it could pose a safety hazard. 2. Springs may also deform over time, as they are constantly in use while driving. Although automotive springs are generally of high quality, it is still advisable to exercise caution.

What do the English buttons in the car mean?

Common English button names are as follows: 1. MUTE: Mute button. 2. MODE: Mode button, used to switch between multimedia modes, namely AM, FM, HE, and USB modes. 3. AMS: In radio mode, press this button for more than 2 seconds to automatically save the received station in preset stations [1-6]. Pressing it briefly allows you to cycle through preset stations [1-6], staying on each for 5 seconds. 4. VOL: Abbreviation for the English word 'volume', which refers to sound level. The plus and minus signs, VOL-/VOL+, correspond to volume control buttons, allowing you to adjust the car audio's volume level.

Where is the car engine air intake located?

Different models have different air intake locations. Some are in front of the engine, while others are at the rear. The position and shape may vary between vehicles, but one common feature is that they are generally located in the engine compartment. When you open the hood, the position of the air filter indicates the location of the car's air intake. The air filter is installed between the intake port and the throttle port, typically shaped as a rectangular plastic housing. Below are the functions of the air filter: 1. Filtering impurities from the air: Ensures the engine operates normally. During engine operation, impurities such as dust and metal shavings can continuously mix into the cylinders. If these accumulate, they can obstruct airflow in the engine, leading to increased fuel consumption over time. 2. Preventing haze from entering the air conditioning system: Without proper car maintenance, moisture and dust can accumulate on the filter, promoting bacterial growth. When the air conditioning is turned on, this not only affects air intake but also contaminates the blower and ducts, causing a series of problems.
