BMS SLEEP WAKE-UP CIRCUIT AND METHOD, BMS, AND ELECTRIC DEVICE

This application discloses a BMS sleep wake-up circuit and method, a BMS, and an electric device. The BMS sleep wake-up circuit is provided with an enabling circuit. When a charging device is plugged in, the wake-up chip can be enabled through a first enabling signal to activate to wake up a BMS, and a control circuit outputs a self-locking signal, so that the wake-up chip keeps waking up the BMS. Additionally, after being activated, a mode in which the wake-up chip is enabled to activate is changed to a mode in which the wake-up chip is enabled through a second enabling signal to activate to wake up the BMS, so that when the charging device remains plugged in, after the self-locking signal is canceled, the wake-up chip is turned off, allowing the BMS to enter a sleeping state.
