Abstract

The invention discloses a power supply guarantee system and a power supply guarantee method. The power supply guarantee system is applied to the battery management system. The power supply guarantee system includes: a main control module, which is used to send the received wake-up time to the timing device; a high-voltage power supply module, which is used to supply power to the timing device according to the electric energy in the high-voltage battery pack; The device is used to set the wake-up clock according to the wake-up time, and starts timing when the battery management system enters sleep mode, and sends a discharge command to the high-voltage battery pack when the timing reaches the wake-up time; the power conversion module is used to discharge the high-voltage battery pack according to the The high-voltage electric energy output by the command is converted into low-voltage electric energy, and the low-voltage electric energy is used to power the battery management system. According to the power supply guarantee system provided by the embodiments of the present invention, when the BMS is in a dormant state, it can continue to provide power for the BMS, so as to ensure the normal operation of the BMS and reduce the loss of lead-acid.

Description

technical field [0001] The invention relates to the field of battery management, in particular to a power supply guarantee system and a power supply guarantee method. Background technique [0002] At present, facing the current situation of energy shortage and increasingly serious environmental pollution, it is imperative to develop pure electric new energy vehicles, which will become an important way to reduce vehicle exhaust emissions, energy consumption and relieve environmental pressure. The battery management system (Battery Management System, BMS) is an important part of the energy management of new energy vehicles, which realizes the intelligent management and maintenance of the power battery system of electric vehicles. [0003] Usually, the lead-acid battery of the whole vehicle provides power for the BMS, and at the same time connects with the low-voltage controller through the power supply bus, and supplies power for the low-voltage controller. In the traditional...
