Title:
BMS SLEEP WAKE-UP CIRCUIT AND METHOD, BMS AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/088014
Kind Code:
A1
Abstract:
A BMS sleep wake-up circuit and method, a BMS and an electric device. In the BMS sleep wake-up circuit, an enabling circuit (120) is provided which can generate, when a charging device (10) is connected, an enabling level of a preset duration to enable a wake-up chip (200) to be started, so as to wake up a BMS in a sleep state; and a control circuit (130) outputs a self-locking signal such that the wake-up chip (200) keeps the BMS awake. In addition, when the charging device (10) is kept connected, upon cancelling the self-locking signal, the wake-up chip (200) is turned off such that the BMS may enter the sleep state, thus solving the problem that the BMS fails to enter the sleep state if the charging device (10) is not pulled out.
