Why are new energy vehicles breaking down so often? The frequent occurrence of new energy vehicle failures is the result of multiple factors. From the technical level, the battery as a core component, its stability directly affects vehicle safety. Currently widely used lithium-ion batteries are susceptible to thermal runaway under extreme conditions such as high temperature, overcharging, and collision, triggering fires or explosions.
Defects in the battery management system may also lead to a decline in battery performance, the inability to accurately monitor and control the battery state, which in turn leads to safety accidents. The charging process also has hidden dangers. Some car owners use non-original chargers or non-standard charging facilities, which can easily lead to overheating and short-circuit problems during the charging process.
In order to pursue low cost and high profit, some new energy vehicle enterprises may cut corners on vehicle safety design, resulting in insufficient structural strength of the body, battery protection measures are not in place and other problems. In the event of a collision, these design flaws may not be able to effectively protect the safety of vehicle occupants, and may even lead to battery damage and cause accidents.
External environmental factors also pose a challenge to the safety performance of new energy vehicles. Under extreme weather conditions such as rainstorms and floods, vehicles are prone to water ingress, leading to short circuits that can cause malfunctions. When driving through water, the water depth exceeding a certain limit may intrude into key components such as battery packs and motors, damaging electronic components.
High-temperature weather will make the battery performance decline, increasing the risk of thermal runaway; low-temperature weather will affect the battery’s charging and discharging efficiency, resulting in shortened vehicle range or even unable to start. Human factor is also an important reason for the frequent occurrence of new energy vehicle accidents. Some drivers are unfamiliar with the performance and operation of new energy vehicles and are prone to misuse.
Why are new energy vehicle failures frequent? Failure to master the strength of acceleration and braking during driving, resulting in loss of control of the vehicle. Some vehicle owners do not follow the norms when charging, and use inappropriate charging equipment or charging methods, which may also cause safety accidents.
