Will the electric vehicle automatically cut off power when fully charged?

Electric vehicles will not automatically cut off power when fully charged. Here is the relevant information: Extended information: If the charging device is not removed after the electric vehicle is fully charged, it will not automatically cut off power. The charging device will continue to charge the battery, but all charging devices have protective mechanisms. After the battery is fully charged, the main charging device will automatically cut off, and the system will enter a float charging state. Float charging refers to the process of continuing to charge the battery with a small current after it is fully charged. At this stage, it is called float charging or trickle charging. Electric vehicles: In China, electric vehicles are mainly used for sightseeing and passenger transport, public security patrols, and cargo transportation. Electric sightseeing vehicles are primarily used in places such as parks, scenic areas, leisure resorts, universities, hospitals, golf courses, and real estate companies for passenger transport. Electric patrol vehicles are mainly used for public security patrols in places like station squares and crowded areas. Electric transport vehicles are primarily used in factories, ports, docks, and logistics warehouses for cargo handling.
As someone who loves delving into technical details, I find the Battery Management System (BMS) in modern electric vehicles incredibly smart. It continuously monitors the battery status during charging. Once the charge reaches 100%, the BMS automatically cuts off the power to prevent overcharging, which could cause damage or shorten battery life—similar to your phone charger but more advanced. Most EV brands, like Tesla or BYD, have this built-in protection mechanism to ensure safety and reliability. In my daily use, I often choose to charge overnight, and once the car stops by itself, I never worry about it. Although some older models or non-standard chargers might pose risks, mainstream EVs are very safe. Regular software updates and avoiding charging in overheated environments can help the system run longer. Remember to check if the dashboard indicators turn off after charging stops, so you can continue using it with peace of mind.
