What are the impacts of a new energy vehicle's chassis being hit?
3 Answers
The impacts of a new energy vehicle's chassis being hit are as follows: 1. Battery impact: Under the impact on the vehicle's chassis, the shell of the power battery pack will suffer significant compression. Similar to how a fuel-powered car's engine has a protective plate underneath, when subjected to impact, this plate can press against the engine oil pan, leading to potential damage. 2. Impact on exhaust system components: The vehicle's exhaust pipe, catalytic converter, and other components in the chassis may be damaged. 3. Impact on wheel alignment parameters: If suspension components such as the control arm are severely hit, the vehicle's wheel alignment parameters may become misaligned, potentially causing the vehicle to pull to one side or even more severe issues like heavy friction and abnormal noises. 4. Impact on the chassis: If the chassis reinforcement components are hit, causing the coating to be scratched or exposing the metal, failure to address it promptly can lead to severe corrosion of the chassis.
Having driven for many years, I've experienced several instances of undercarriage scrapes. The potential risks are significant when the undercarriage of a new energy vehicle is hit, mainly because the battery pack is positioned low and prone to damage. A single pothole impact can lead to battery casing rupture, liquid leakage, or internal cell short circuits, posing a risk of spontaneous combustion. The last time I encountered a similar situation, the car's alarm system lit up red, prompting me to stop and inspect immediately. If the suspension system is damaged, you may feel instability and poorer handling while driving. It's advisable to slow down and stop immediately after a scrape, checking for any fluid leaks or unusual odors, and avoid driving recklessly. Minor issues might only require repairing the protective plate, costing a few hundred yuan; however, battery damage can incur high repair costs, even tens of thousands. Try to avoid high curbs or speed bumps in daily driving and regularly inspect the thickness of the undercarriage protective layer.
As a budget-conscious car owner, I dread the extra costs from undercarriage impacts. The battery of a new energy vehicle is expensive, and if a module is damaged from a hit, replacement can easily exceed tens of thousands. Insurance may not cover it fully, depending on the nature of the accident. A cracked guard plate might seem minor, but debris entering the damaged area can corrode the chassis structure. Repairs also take time, sometimes waiting for parts. My advice is to take a short test drive after a hit, listening for unusual noises to gauge severity; otherwise, the problem may worsen and become harder to fix. Usually, slowing down on rough roads saves both trouble and money.
