BATTERY MONITORING SYSTEM WITH OVERCURRENT AND UNDERCURRENT PROTECTION CIRCUIT AND PROTECTION METHOD FOR OVERCURRENT AND UNDERCURRENT THEREOF

摘要

A battery monitoring system having an overcurrent and undercurrent protection circuit according to a preferred embodiment of the present invention includes a voltage sensing unit for sensing the voltage of a battery cell, and balancing of the battery cells based on the sensing result of the voltage sensing unit A balancing switch, when an overcurrent flows to the output terminal of the balancing switch, an overcurrent protection circuit that blocks the flow of the overcurrent, and when a low current flows to the output terminal of the balancing switch, a low that supplies an additional current to the output terminal of the balancing switch Includes a current protection circuit.
