Power Bank's Fault Self-Test Function
The fault self-test function is an essential safety feature of modern power banks, designed to automatically detect potential malfunctions during use, alert users in a timely manner, and prevent safety hazards such as overheating, short circuits, and battery leakage. This function is realized through the built-in intelligent control chip and various sensors (such as temperature sensors, current sensors, and voltage sensors) in the power bank, which continuously monitor the working status of the power bank, including battery voltage, charging/discharging current, internal temperature, and circuit connection status, and conduct real-time self-inspection to identify abnormal conditions.The fault self-test function covers a variety of common malfunctions, including battery overcharge, over-discharge, over-current, over-temperature, short circuit, and poor contact. When the power bank detects an abnormal condition, it will take corresponding protective measures immediately, such as cutting
