SCHOTT SEFUSE® D6 battery protection devices are designed to protect Li-ion batteries from potentially damaging and dangerous overcurrent and overcharging circumstances. The components are thin/compact, surface mounted devices and are suitable for high currents and compatible with up batteries having up to 14 cells
In cases of overcurrent situations, the fuse element will open and cut off the circuit. In cases of overcharging, a field-effect transistor (FET) is activated and the heater element in the D6S device disables the fuse element, resulting in the circuit being cut off. Compliance with the manufacturer’s installation instructions must be followed. In addition, sufficient testing must be performed with review of all testing data to determine the optimal design for a particular application
Applications include battery packs used in rechargeable power / garden tools, cordless and robotic vacuum cleaners, E-bikes and E-motorcycles, energy storage systems, notebook PC’s, tablet PC’s and smartphones
