Title:

POWER SUPPLY ENSURING SYSTEM AND POWER SUPPLY ENSURING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/008354

Kind Code:

A1

Abstract:

A power supply ensuring system and a power supply ensuring method. The power supply ensuring system (200) is used in a battery management system (102), the power supply ensuring system (200) comprising: a master control module (40), used for sending a received wake-up time to a timing apparatus (30); a high-voltage power supply module (20), used for supplying power to the timing apparatus (30) on the basis of the electrical energy in a high-voltage battery pack (10); a timing apparatus (30), used for setting a wake-up clock on the basis of the wake-up time, starting timing when the battery management system (102) enters sleep, and sending a discharge command to the high-voltage battery pack (10) when the timing reaches the wake-up time; and a power source conversion module (50), used for converting the high-voltage electrical energy outputted by the high-voltage battery pack (10) on the basis of the discharge command into low-voltage electrical energy, and using the low-voltage electrical energy to supply power to the battery management system (102). On the basis of the present power supply ensuring system (200), power can continue to be supplied to the battery management system (102) when the battery management system (102) is in a sleep state, ensuring the normal operation of the battery management system (102), and reducing the lead acid battery loss.
