How long should you continue charging after the electric vehicle's green light turns on?

After the electric vehicle's charging green light turns on, continue charging for two more hours. Since the battery voltage fluctuates within the charging voltage range and the battery plate corrosion is at its slowest state, extending the charging time by two hours can also prolong the battery's lifespan. Below are some precautions for electric vehicle charging: 1. Avoid parking with a dead battery: When an electric vehicle is parked with insufficient power, the battery is prone to sulfation, which blocks ion channels, leading to insufficient charging and reduced battery capacity. Therefore, when the electric vehicle is idle, keep its power active. 2. Perform regular deep discharges: When an electric vehicle runs out of power, it will automatically enter under-voltage protection. However, during this process, the voltage is unstable and fluctuates up and down, causing repeated under-voltage protection. Therefore, it's best to perform regular deep discharges on the battery, fully discharging it before recharging, which will provide good protection for the battery.
As a regular commuter who frequently rides an electric bicycle, I remember several times when charging at night, I would unplug it as soon as the green light came on, and the battery would last two to three years without any issues. From my experience, the green light usually indicates that the battery is nearly fully charged, around 95% to 100%. If you continue charging beyond this point, the battery may overheat or even swell, significantly shortening its lifespan in the long run. I recommend developing a good habit: unplug the charger immediately or within an hour after the green light turns on—don’t be greedy for that extra bit of charge. Additionally, place the charger in a well-ventilated area and avoid charging in high-temperature environments—safety first. If you tend to forget, setting a phone alarm as a reminder works well—this simple method has saved me a lot of hassle.
