Does unplugging an electric vehicle before it's fully charged have any impact?

Unplugging an electric vehicle before it's fully charged does have an impact. Currently, most electric vehicle batteries are lead-acid batteries, which have a certain number of charge-discharge cycles, typically around 350 to 370 times. If you unplug before it's fully charged, it's equivalent to wasting one full charge opportunity and can accelerate the rate of battery water loss. Over time, this can also cause the battery to swell, affecting its lifespan. Once a battery swells, it cannot be repaired and must be replaced. Electric vehicles, or electric-driven vehicles, are divided into AC and DC types. Typically, electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through components like controllers and motors, with speed controlled by adjusting the current.
