The invention belongs to the technical field of vehicle engineering, and particularly discloses an appointment charging circuit which comprises a microprocessor used for managing the working state of the charging circuit; the CP signal processing module is used for receiving the CP signal from the slow charging pile and processing the CP signal into a CPWake signal; the Tbox is used for receiving instructions from a remote control end and forwarding the instructions to the microprocessor, and the instructions comprise that appointment time is up/not up and appointment charging can be started/not can be started; and the local communication module communicates with the Tbox, when the instruction indicates that reserved charging can be/cannot be started, the local communication module outputs a reserved charging control signal, and when the reserved charging control signal or a CPWake signal indicates that charging can be started, the microprocessor is awakened. The method has the advantages that when the charging gun is inserted into the charging port of the vehicle, the vehicle can be awakened, if the appointment charging time set by the APP is not reached or the vehicle is fully charged in the immediate charging state, the vehicle can automatically enter the dormancy state, and the energy loss of the lead-acid battery is reduced.
本发明属于车辆工程技术领域,具体公开了一种预约充电电路,包括:微处理器,用于管理充电电路的工作状态;CP信号处理模块,接收来自慢充充电桩的CP信号,并处理为CP_Wakeup信号;Tbox,接收来自远程控制端的指令并将指令转发给微处理器,其中,指令包括预约时间到/未到,可以/不可以开始预约充电;本地通信模块,与Tbox通信,当指令指示可以/不可以开始预约充电时,本地通信模块输出预约充电控制信号,预约充电控制信号或CP_Wakeup信号指示可以开始充电时,微处理器被唤醒。本发明的优点在于充电枪插入车辆充电口时,车辆能被唤醒,如果未达到APP设定的预约充电时间或立即充电状态下已经充满时,车辆能自动进入休眠,减少对铅酸电池能量的损耗。
