Will the Battery of an Electric Vehicle Be Affected If the Chassis Is Hit?

If the chassis of an electric vehicle is hit, observe whether the SOC (State of Charge) displayed on the instrument cluster is normal. If it shows normally, it indicates the battery is unaffected; if not, it suggests an impact. Below is relevant information on factors causing battery degradation in electric vehicles: 1. Natural Degradation; During long-term use, mutual friction and wear between components, corrosion by various media, and the effects of high temperatures and alternating loads lead to material fatigue, deformation, and aging. Due to these natural degradation influences, certain parts may fail, creating a vicious cycle that ultimately results in various malfunctions. Natural degradation accounts for a significant proportion of common faults. 2. Inherent Design and Manufacturing Flaws; Unreasonable structural design, insufficient strength, and substandard material selection; defective parts, low precision, and manufacturing processes that fail to meet specifications; assembly and adjustments not conforming to technical requirements—these factors lead to inherent quality issues in vehicles, creating potential faults. Due to poor design, low manufacturing precision, and inferior quality, the vehicle may not meet normal operational requirements, leading to faster fault occurrences. This is also a primary cause of malfunctions. 3. Improper Maintenance; Different vehicle models, due to variations in structure and materials, have specific maintenance measures and requirements set by manufacturers. Neglecting maintenance or failing to adhere to technical requirements during use can degrade the vehicle's condition, preventing the restoration of its original technical performance and accelerating fault occurrences. For example, neglecting timely lubrication with the specified oil quality at lubrication points will accelerate component wear, potentially leading to severe issues like bearing seizure, cylinder scoring, or knocking sounds. Clearly, improper maintenance increases faults, making it another significant cause of common malfunctions.

Can a Lost Car Key Be Tracked?

Lost car keys cannot be tracked. If you lose your car keys, you can contact a professional locksmith to unlock the car and then visit a 4S dealership to have a new key made. Relevant documents such as your ID card and vehicle registration certificate will be required. If you don't have the vehicle registration certificate, you'll need to file a report at the local police station. Handling Lost Mechanical Keys: Mechanical keys are relatively small, and while spare keys are usually prepared, they can also be easily lost. If you lose a mechanical key, you can contact a car key service company or a locksmith to make a duplicate based on the spare key. However, if someone with malicious intent finds the key and locates your car, they could unlock it. If you have valuable items in the car, it's recommended to replace the entire mechanical lock system. Handling Lost Chip Keys: Chip keys contain an embedded chip, providing both mechanical and electronic anti-theft functions, as well as engine start and engine immobilizer features. If you lose a chip key, you must visit a 4S dealership to replace it, as they have the original chip information needed to reprogram a new key. Precautions When Replacing Key Batteries: When replacing the battery, carefully observe the front and back sides to ensure the correct alignment of the positive and negative terminals. Avoid using excessive force when removing the battery to prevent damage to the key's casing and internal chip.

Can expired car wax still be used?

Expired car wax cannot be used. Here are the specific reasons why expired car wax should not be used: 1. Deterioration: Some substances in expired products may undergo qualitative changes, potentially producing substances with opposite effects. 2. Grease buildup: To achieve a good glossy effect, a relatively thick layer of wax is required. However, car wax is an oily substance with poor adhesion between the oil film and the paint surface, offering short protection duration. This type of wax often washes away due to rain or cleaning, sometimes even adhering to the windshield and forming grease buildup. Therefore, car waxing should be performed regularly.
