This application discloses a power supply guarantee system and a power supply guarantee method. The power supply guarantee system is applied to a battery management system (BMS). The power supply guarantee system includes: a main control module, configured to send a received wake-up time to a timing device; a high voltage power module, configured to power the timing device according to electrical energy in a high voltage battery pack; the timing device, configured to set a wake-up clock according to the wake-up time, start timing when the BMS enters sleep, and send a discharge instruction to the high voltage battery pack when the timing reaches the wake-up time; and a power conversion module, configured to convert high voltage electrical energy into low voltage electrical energy, and use the low voltage electrical energy to power the BMS, where the high voltage electrical energy is output by the high voltage battery pack according to the discharge instruction. According to the power supply guarantee system disclosed herein, when the BMS is in a sleep state, a power supply keeps being provided to the BMS to ensure normal operation of the BMS and reduce loss of lead acid.
