Abstract

This application involves a dormant wake -up control circuit, charging control system and vehicle.In the wake -up control circuit, the signal conversion circuit is used to connect to the dropped resistor inside the charging gun when the charging socket is inserted into the target battery, convert the resistance signal of the drop -down resistor to the dormant awakening signal, and send the dormant wake -up signal to the battery to the batteryThe wake -up signal receiving end of the management system is started with the battery management system after receiving the dormant wake -up signal to achieve charging control of the target battery. The resistance detection circuit is used to connect to the drop -resistant resistance when the charging socket is inserted into the charging socket, and the output is output, and the output is output.The target voltage signal is sent to the voltage signal receiving end of the battery management system to the voltage signal receiving end of the battery management system.The dormant wake -up control circuit provided by this application embodiment can be compatible with processing different types of charging guns on the market to meet the various charging needs of new energy vehicles.

Description

technical field [0001] The present application relates to the technical field of design and manufacture of new energy vehicles, and in particular, to a sleep-wake-up control circuit, a charging control system and a vehicle. Background technique [0002] With the increasingly strict environmental protection policies in various countries around the world and the increasing awareness of energy crisis, new energy vehicles are rapidly popularizing and 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. However, whether it is fast charging or slow charging, a pull-down resistor needs to be set inside the charging gun to ensure that the new energy vehicle is charged during the charging process. By detecting the resistance signal of the pull-down resistor, confirm whether the charging gun is connected to the charging socket of the power batt...
