Is There Any Impact If the Electric Vehicle Charger Is Not Unplugged After Full Charge?

Leaving the electric vehicle charger plugged in after a full charge can have negative effects. If the power is not disconnected in time, prolonged floating charge can cause severe water loss and impact the battery's lifespan. Charging Precautions: Generally, after the electric vehicle charger turns green, an additional 1-2 hours of floating charge is sufficient. The total charging time should typically be controlled within 8-10 hours and should not exceed 12 hours. Overnight charging often exceeds 12 hours. Overcharging an electric vehicle battery can lead to excessive gas generation, which erodes the battery plates, causing active material shedding and ultimately reducing the battery's service life. Battery Lifespan: Under ideal conditions, the number of charging cycles can reach approximately 1,000-2,000 while maintaining over 70% of usable capacity. For PHEVs (Plug-in Hybrid Electric Vehicles), a single charge cycle typically covers about 50-80 kilometers. Therefore, before the battery reaches the end of its life, it can generally provide around 100,000 kilometers of pure electric driving.
