Abstract

The invention relates to a sleep wake-up control circuit, a charging control system and a vehicle. In the sleep wake-up control circuit, a signal conversion circuit is used for being connected with a pull-down resistor in a charging gun when the charging gun is inserted into a charging socket of a target battery, converting a resistance signal of the pull-down resistor into a sleep wake-up signal, and sending the sleep wake-up signal to a wake-up signal receiving end of a battery management system; so that the battery management system starts to work after receiving the sleep wake-up signal to achieve the charging control of the target battery; the resistance detection circuit is used for being connected with the pull-down resistor when the charging gun is inserted into the charging socket, outputting a target voltage signal and sending the target voltage signal to a voltage signal receiving end of the battery management system, so that the battery management system calculates the resistance value of the pull-down resistor according to the target voltage signal. The sleep wake-up control circuit provided by the embodiment of the invention can process different types of charging guns in the market in a compatible manner, and various charging requirements of new energy vehicles are met.

Description

technical field [0001] This application relates to the technical field of design and manufacture of new energy vehicles, in particular, to a dormancy wake-up control circuit, a charging control system and a vehicle. Background technique [0002] With the increasingly stringent environmental protection policies of countries around the world and the increasing awareness of energy woes, new energy vehicles are rapidly becoming popular and have become one of the most potential means of transportation in the new era. In terms of charging speed selection, the charging of new energy vehicles is divided into fast charging and slow charging. By detecting the resistance signal of the pull-down resistor, confirm whether the charging gun is connected to the charging socket of the power battery. [0003] However, under normal circumstances, the resistance signal of the pull-down resistor cannot directly meet the dormancy wake-up condition of the battery management system (the dormancy w...
