The invention relates to a power supply control device, a vehicle-mounted TBOX and a control method of the power supply control device. The power supply control device comprises a vehicle-mounted standby energy storage module; the power supply switching module is connected with a power supply interface of the vehicle-mounted TBOX, the vehicle-mounted standby energy storage module and the vehicle-mounted main energy storage module, and is used for controlling the vehicle-mounted main energy storage module to supply power to the power supply interface in a main power supply mode; the power supply switching module is also used for controlling the vehicle-mounted standby energy storage module to supply power to the power supply interface in the standby power supply mode; the power supply switching module is further used for receiving a standby power switching-off instruction and forbidding switching from the main power supply mode to the standby power supply mode when the standby power switching-off instruction is received; and the signal processing module is connected with the power supply switching module and is used for sending a standby power switching closing instruction to the power supply switching module when receiving the maintenance preparation prompt instruction. By adopting the method, the situation that communication cannot be established with the vehicle emergency call system due to insufficient electric quantity of the vehicle-mounted standby battery when the vehicle is maintained can be prevented.
本申请涉及一种供电控制装置、车载TBOX和供电控制装置的控制方法。所述供电控制装置包括:车载备用储能模块;供电切换模块,连接车载TBOX的供电接口、车载备用储能模块和车载主储能模块,用于在主供电模式时,控制车载主储能模块向供电接口供电;供电切换模块还用于在备用供电模式时,控制车载备用储能模块向供电接口供电;供电切换模块还用于接收关闭备电切换指令,并在接收到关闭备电切换指令时,禁止从主供电模式切换至备用供电模式;信号处理模块,连接供电切换模块,用于在接收到准备维修提示指令时,向供电切换模块发送关闭备电切换指令。采用本方法能够防止在车辆维修完成时因车载备用电池电量不足导致的无法与车辆紧急呼叫系统建立通信。
