Will the Battery of an Electric Vehicle Be Affected If the Chassis Is Hit?
2 Answers
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.
After driving an electric vehicle for several years, I've learned that a collision to the chassis can indeed affect the battery life, since the battery pack is installed underneath. If the impact occurs in the wrong place, like hitting a pothole or a severe scrape, a cracked battery casing or internal short circuit can cause the battery to drain faster, directly reducing the range. Once, my car's chassis was scraped by a rock, triggering the battery temperature warning light, and the battery level dropped from full to less than half. I didn't dare to continue driving, fearing a fire. Now, I regularly check the chassis protective plate or try to avoid rough roads. When charging, I also pay attention to the battery status—unstable battery levels can prolong charging time, making it both troublesome and costly. For safety, it's advisable to visit a 4S shop immediately after any impact, to prevent major issues from developing.
