What are the causes of power battery failure in new energy vehicles?
2 Answers
New energy vehicle power battery failures may be caused by fuse malfunctions, loose wiring connectors, damaged power switches, motor failures, etc. Here is a detailed introduction about new energy vehicles: 1. Overview: New energy vehicles refer to automobiles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in advanced technical principles, new technologies, and new structures. 2. Others: New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, hydrogen engine vehicles, etc. A pure electric vehicle is one that uses a single battery as the energy storage power source.
There are quite a few reasons for power battery failures in new energy vehicles, as I've personally experienced with my electric car. Mainly, my poor usage habits, like frequently draining the battery almost completely before charging, have led to severe over-discharge, accelerating battery degradation. Additionally, frequent use of fast-charging stations can easily cause internal aging when temperatures rise, resulting in a rapid drop in range. Parking under the scorching sun in summer can lead to thermal management failure, causing the battery to overheat and risk short circuits. Physical damage, such as unnoticed hazards from vehicle collisions, is another factor. Now, I've learned to keep the battery charge within a reasonable range and control the temperature, which has significantly reduced failures.
