Three terminal fuse.solar battery fuse

　　Three terminal fuses are chip based surface mount products, commonly used as secondary protection for lithium-ion battery packs to act promptly when damaged by excessive current and overcharged voltage, effectively protecting lithium-ion batteries from fires caused by overcurrent and overcharging. The three terminal fuse adopts an extremely thin and compact surface mount packaging (SMD), and is compatible with up to 14 battery cells. At the same time, to facilitate the solution of different product design needs of users, Linda can provide a variety of three terminal fuse product solutions to meet the requirements of different currents and packaging sizes.

　　Three terminal fuse applications include:

　　Wireless vacuum cleaners and sweeping robots, rechargeable electric tools, Garden tool, laptops, electric bicycles, electric motorcycles, uninterruptible power supplies, portable energy storage and other products.

　　Internal structure and working principle of three terminal fuse:

　　Consisting of three terminals, two fuses made of alloy metal are connected in series. When the charging current exceeds the rated value and passes through the fuse, the fusible alloy inside the fuse melts and quickly cuts open the circuit,

　　The function of the intermediate series heater is to form a series circuit with the FET (Field Effect Transistor) in the circuit. When the system detects overcharging of the battery, the FET in the circuit is activated, and the heater inside the fuse heats up, causing the melting alloy to burn out and cause the circuit to be cut off,home energy storage system battery
