The invention discloses a power supplementing device and method and electric equipment. The detection control module is used for detecting the voltage of the storage battery and sending a wake-up signal and a charging request when the voltage of the storage battery meets a preset charging condition; a switch module; the vehicle control unit is used for switching from a dormant state to a wake-up state in response to the wake-up signal under the condition that the switch module is turned on, and charging the storage battery in response to the charging request under the wake-up state under the condition that the vehicle meets the high-voltage power-on condition; the vehicle control unit is further used for obtaining the number of times of electricity supplement faults under the condition that the vehicle does not meet the high-voltage power-on condition; when the electricity supplement fault frequency is greater than or equal to a first preset threshold value, the switch module is controlled to be switched off; and entering a dormant state after the switch module is switched off. According to the embodiment of the invention, the problem of device loss caused by repeated dormancy awakening or non-dormancy of the vehicle control unit under the condition that a power supply request exists but a high-voltage power-on condition is not met can be avoided.
本申请公开了一种补电装置、方法及用电设备。检测控制模块,用于检测蓄电池的电压,在蓄电池的电压满足预设补电条件时,发出唤醒信号和补电请求;开关模块;整车控制器,用于在开关模块开启的情况下,响应于唤醒信号,从休眠状态切换为唤醒状态,以及在唤醒状态下,响应于补电请求,在车辆符合高压上电条件的情况下,对蓄电池进行补电;整车控制器还用于在车辆不符合高压上电条件的情况下,获取补电故障次数;在补电故障次数大于或等于第一预设阈值时,控制开关模块断开;以及在开关模块断开后,进入休眠状态。本申请实施例能够避免在有补电请求但不满足高压上电条件的情况下,造成的整车控制器反复休眠唤醒或一直不休眠导致的器件损耗问题。
