What does it mean when SOC reaches the limit value and terminates?

soc reaches the limit value and terminates means charging is completed or when the battery level is below 15% or 5%, power output will be restricted. The following is an introduction to automotive SOC and other indicator lights on the car dashboard: Automotive SOC: The full name is State of Charge, which refers to the battery's state of charge, also known as remaining battery capacity. It represents the ratio of the remaining dischargeable capacity after the battery has been used for a period or left unused for a long time to its fully charged capacity, usually expressed as a percentage. Other indicator lights: The hazard warning light is used to alert other vehicles and pedestrians when the car has a major malfunction or emergency situation; the hazard warning signal is indicated by the simultaneous flashing of the front, rear, left, and right turn signals; the battery indicator light shows the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts; if it does not light up or stays on continuously, the generator and circuit should be checked immediately; the fuel indicator light is a warning for insufficient fuel. When this light comes on, it means the fuel is almost exhausted. Generally, the vehicle can still travel about 50 kilometers from the time the light comes on until the fuel is completely depleted.
The SOC of a battery stands for State of Charge, much like the battery percentage on a phone, indicating how much power is left in the battery. When it reaches the limit and terminates, it means the vehicle's system detects that the charge is either too high or too low, such as at a full charge of 100% or nearly empty at 20%, and will automatically stop charging or discharging to protect the battery from damage. I've experienced this before when driving an electric car—the charger automatically stopped once the battery was full, and the system displayed 'terminated.' This design primarily prevents overcharging, which could lead to fires, or over-discharging, which shortens battery life. Overheating the battery is dangerous and can damage the car, leading to costly repairs. For daily driving, I recommend not charging the battery to full capacity; setting an 80% limit is safer. Make it a habit to check the battery level via the app, and if you notice any abnormalities, get it inspected and serviced promptly to avoid being stranded on the road.
