Abstract

This invention relates to the field of electrical measurement and fault diagnosis technology, specifically to a battery pack voltage and electrical performance monitoring device. It includes a data acquisition module comprising a housing and a main board disposed inside the housing. The main board is connected to a data acquisition line and a communication line, and is normally powered through the data acquisition line. The housing contains a switching mechanism and a base plate at its bottom. The switching mechanism includes a conductive arm connected to an adjacent battery and a conductive sheet connected to the main board; the conductive sheet is an elastic structure. This monitoring device, by pre-setting a circuit inside the housing that is normally disconnected and by using a base plate slidably connected to it at the bottom of the housing, allows the disconnected circuit to be reconnected simply by moving the housing when a battery malfunctions. This enables the data acquisition module to draw power from adjacent batteries, improving operational efficiency.
