Title:
POWER-ON/OFF CIRCUIT FOR BATTERY MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/128714
Kind Code:
A1
Abstract:
A power-on/off circuit for a battery management system, comprising a drive signal input end (VLSP), a power-on drive signal output end (On_Aux_Pwr), a power supply end (DC_IN+, DC_IN-), a power supply signal extraction circuit (100), a trigger circuit (200) and a switch (300). The drive signal input end (VLSP) is connected to the power-on drive signal output end (On_Aux_Pwr) by means of the switch (300); the power supply signal extraction circuit (100) is connected to the power supply end (DC_IN+, DC_IN-) and is used for outputting a control signal on the basis of a power supply signal connected to the power supply end (DC_IN+, DC_IN-); and the trigger circuit (200) is electrically connected to the power signal extraction circuit (100), and the trigger circuit (200) is used for controlling the switch (300) to be turned on or off according to the transition of the control signal. The power-on/off circuit receives, by means of the trigger circuit (200), a power-on or power-off signal output by the power supply signal extraction circuit (100), thereby implementing unified management of power-on/off signals. The power-on/off circuit is easy to expand, and has strong reusability.
