Abstract

The invention relates to the technical field of power management devices for electric vehicles, in particular to a power management system and method based on a vehicle controller. The power management system includes a power management chip, the input end of a first power output enable signal of the power management chip is electrically connected with a power start switch, and the input end of the first power output enable signal is further electrically connected to the output end of the first power output enable signal of the vehicle controller; and the output end of a first power source corresponding to the first power output enable signal is electrically connected to the vehicle controller, and the output end of a second power source is electrically connected to electrical devices. According to the power management system and method based on the vehicle controller, the input end of the first power output enable signal of the power management chip is electrically connected with thevehicle controller and the power start switch, power-down timing sequence can be realized with no additional circuits required, and the difficult problem that a power start signal can enable a power management circuit and be monitored at the same time is solved.

Description

technical field [0001] The invention relates to the technical field of power management equipment for electric vehicles, in particular to a power management system and method based on a vehicle controller. Background technique [0002] The vehicle controller is the core control unit of new energy vehicles. At present, with the encouragement of national policies and the continuous development and competition of car manufacturers, the functions of the vehicle are constantly becoming stronger and better. At the same time, the function and performance requirements of the vehicle controller are also increasing The corresponding increase has resulted in an increase in the static power consumption of the vehicle controller hardware. At the same time, the vehicle controller needs to perform a power-off delay when powering off to realize the storage of important data and the power-off sequence of related equipment. deal with. [0003] Therefore, in order to solve the above problems,...
