Abstract

The invention relates to an awakening method and device of an on-board charger. After first preset time is reached, the dormancy state is changed into the low-power-consumption state, whether an awakening signal exists or not and whether the awakening signal is effective or not are detected within second preset time, and once the awakening signal is detected and is effective, the on-board chargeris awakened to work. Since a controller is in a dormancy state within the first preset time, the power consumption of the on-board charger is reduced. Since the controller only detects whether the awakening signal exists or not within the second preset time, it can be avoided that since the awakening signal exists all the time, the controller jumps out of the dormancy state to enter the low-power-consumption state all the time, and therefore the power consumption of the on-board charger is reduced, and the requirement for ultra-low power consumption is met.

Description

technical field [0001] The invention relates to the technical field of on-board chargers, in particular to a wake-up method and device for on-board chargers. Background technique [0002] With the development of automotive electronics, the frequency of car replacement is getting higher and higher, and the car is gradually shifting from the original mechanical parts to electronic parts. People have higher and higher requirements for electronic equipment in the car, and lightweight , Electronics and intelligence are key factors that must be considered in the development of modern automobiles. Especially in the new energy vehicles developed in recent years, the number of electronic and intelligent equipment in the vehicle has increased significantly compared with traditional vehicles. [0003] While the increase of these electronic devices brings safety and convenience to consumers, it also brings great challenges to the power consumption of the whole vehicle. During the drivi...
