At What Battery Level Should a New Electric Vehicle Be Charged?

Regarding the question of how much remaining battery is appropriate for recharging new energy pure electric vehicles, Hydrogen Cloud Chain's research on relevant vehicle models' reports indicates that the optimal charging range is between 20% and 90%. Charging within this range can minimize the impact on the power battery and effectively extend its service life. Power Battery: As is well known, the current domestic power batteries are mainly ternary lithium and lithium iron phosphate. Ternary lithium batteries are most afraid of overcharging and over-discharging. Overcharging can lead to fires, while over-discharging (complete depletion) can cause the entire battery to fail. Low Battery Warning: To prevent new energy vehicles from discharging completely, some manufacturers set a low battery warning at around 15%. Of course, the vehicle is not immobilized at this point and still has a certain driving range left. If you continue to drive, the vehicle's speed will be limited. Even if you press the accelerator pedal all the way down, the vehicle's speed can only be maintained at around 40 km/h.

Can Small Flatbed Trucks Drive on Highways?

Small flatbed trucks can drive on highways. Vehicles allowed on highways: Motor vehicles designed with a speed higher than 70 kilometers per hour are permitted to enter highways. In real life, each province has formulated additional regulations, measures, and other rules based on the actual conditions of their highways. For example, some provinces allow motorcycles on highways, while others do not. Vehicles not allowed on highways: Article 67 of the Traffic Safety Law: Pedestrians, non-motor vehicles, tractors, wheeled special-purpose machinery vehicles, articulated buses, full trailers, and other motor vehicles designed with a maximum speed lower than seventy kilometers per hour are not allowed to enter highways.

What Causes the Noise When Stepping on the Brake and Turning the Steering Wheel in Place?

The noise is mainly caused by the friction between the tires and the ground, as well as noises from the brake discs, steering system, and suspension system. When turning the steering wheel in place, the steering wheels do not rotate around their geometric centers but rather roll slightly because the rotation center of the tire is not at its geometric center but at the rotation center of the steering knuckle. Therefore, from a microscopic perspective, the wheels perform a circular roll centered on the steering knuckle axis when turning in place. Noise occurs when turning the steering wheel in place: This phenomenon is more common in vehicles with mechanical hydraulic power steering (HPS), which is a mature and cost-effective technology. Mechanical hydraulic power steering converts part of the engine's power into hydraulic pump pressure, which then applies force to the steering system to turn the tires. When the steering wheel is kept straight, the pressure on both sides of the piston is equal. Once the steering wheel is turned, the mechanical control valve connected to the steering column opens. Tire squealing noise due to friction: When stepping on the brake and turning the steering wheel in place, the friction between the wheels and the ground produces a squealing noise. The increased force on the steering system can cause vibrations, resulting in a clunking sound. Although the suspension system is also under stress, it usually does not produce noise unless there are pre-existing issues, which might lead to cracking or creaking sounds. Of course, it's not entirely forbidden to step on the brake and turn the steering wheel in place, as there are situations, such as making tight turns in narrow spaces, where it is necessary. Therefore, it's not something to completely avoid—just minimize it when possible. If you must step on the brake and turn in place, avoid pressing it too hard; a light touch to restrict vehicle movement is sufficient.

Can New Cars Have Paint Runs?

Generally, new cars should not exhibit paint runs. This phenomenon typically occurs only after repairs when the affected area has undergone bodywork and repainting, and the issue was not noticed during delivery or when the car's paint was not fully dried. Carefully inspect the vehicle when selecting: When choosing a car, pay attention to the details of the vehicle. The paint surface is the most basic inspection item. If there are burrs, runs, or color discrepancies, the next steps involve checking the engine compartment and assemblies. If there are obvious irregular welds, signs of removed or damaged rust-proof paint on screws and nuts, or color differences in the engine compartment, these cars are likely to be transport-repaired vehicles. Identifying whether a new car has been repainted: Examine the edges and seals. Look closely at the body's edge joints, seals, trim pieces, and rubber strips for any residual paint marks. If the car has been repainted, these areas will inevitably show traces. Pay special attention to the paint on the engine hood. If you notice that the paint's fullness is inferior to the original, or if there are signs of orange peel, runs, pinholes, bubbles, cracks, discoloration, or putty marks on the surface.

Is there a fee for renewing a driver's license?

Renewing a driver's license requires payment. Driver's License: A driver's license, officially known as a motor vehicle driving license or simply "license," is a legal document required for individuals to operate motor vehicles. Driving a motor vehicle necessitates 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. License as a Permit: For those who have acquired safe driving skills, the document that permits them to drive vehicles on the road is the "driver's license." This indicates that a driver's license is a form of "permit." The authorization to drive a vehicle is granted through the issuance of a driver's license.

Can the bottom of the engine be jacked up with a jack?

The bottom of the engine cannot be jacked up with a jack, as it may damage the engine. Proper jacking points: Every vehicle has designated jacking points specifically designed for using a jack. Most cars have these points located along the edges of the chassis near the wheels. Typically, there is a protruding edge along the vehicle's underbody with several reinforced areas marked for jack placement. Precautions when using a jack: When using a jack to lift the vehicle, always choose a firm and level surface, and ensure the parking brake is fully engaged. The jack's lifting point must be positioned precisely at the chassis support points. Failing to do so may result in unstable vehicle positioning, potential damage to the jack, or even harm to the vehicle's chassis.
