Abstract:
1. A battery protection and monitoring system, comprising: a plurality of MAFET (Mechanically Actuated Field Effect Transistor) switches, wherein each MAFET switch among said plurality of MAFET switches is switched from an open switch condition to a closed switch condition or vice versa, said plurality of MAFET switches connected to a battery; a plurality of MOSFET transistors connected to communicate electrically with at least one MAFET switch among said plurality of MAFET switches; and a PPTC (Polymeric Positive Temperature Coefficient) device connected to said plurality of transistors and said plurality of MAFET switches, wherein said PPTC device, said plurality of MAFET switches and said plurality of transistors operate with one another and said open switch condition or said closed switch condition of said plurality of MAFET switches to identify, monitor and prevent at least one dangerous condition of said battery.
