Mems based battery monitoring

摘要

A battery protection and monitoring system includes a plurality of MAFET (Mechanically Actuated Field Effect Transistor) switches, wherein each MAFET switch among the MAFET switches is capable of switching from an open switch condition to a closed switch condition or vice versa, such that the plurality of MAFET switches are connectable to a battery. Such a system further includes one or more transistors associated with and which communicate electrically with at least one MAFET switch among the MAFET switches. A PPTC (Polymeric Positive Temperature Coefficient) device is also associated with the transistors and the MAFET switches, such that the PPTC device, the MAFET switches and the transistors operate in association with one another and the open switch condition or the closed switch condition of the plurality of MAFET switches to identify, monitor and thus prevent at least one dangerous condition associated with the battery.
