The invention discloses a charger system, a charger and an electric vehicle, and the charger system comprises a power module which supplies power to the charger when the charger is awakened; the awakening module comprises an awakening chip connected with a first detection point in the awakening module, the voltage of the first detection point is reduced when the CC resistor is connected to the charger system, and the charger is awakened to charge the to-be-charged equipment when the awakening chip detects that the voltage of the first detection point is reduced to a preset awakening voltage; and the control module is used for controlling the CC resistor to be connected with the power supply module to increase the voltage of the first detection point when the charger is awakened, controlling the CC resistor to be disconnected from the power supply module to reduce the voltage of the first detection point to be below a preset awakening voltage when the to-be-charged equipment is fully charged, and then controlling the power supply module to stop supplying power to enable the charger to sleep. The charger system provided by the invention can prevent the charger from being mistakenly awakened when entering the low-power-consumption mode from the normal mode, and ensures that the charger can smoothly sleep to enter the low-power-consumption mode.

    本发明公开了一种充电机系统、充电机及电动汽车,充电机系统包括:电源模块,当充电机被唤醒时为充电机供电;唤醒模块,包括与唤醒模块中第一检测点连接的唤醒芯片,CC电阻接入充电机系统时第一检测点的电压降低,当唤醒芯片检测到第一检测点的电压降低至预设唤醒电压时唤醒充电机为待充电设备充电;控制模块,当充电机被唤醒时控制CC电阻连接电源模块使第一检测点的电压升高,当待充电设备充满电时先控制CC电阻与电源模块断开连接使第一检测点的电压降低至预设唤醒电压以下,再控制电源模块停止供电使充电机休眠。本发明提出的充电机系统能避免充电机从正常模式进入低功耗模式时被误唤醒,保证充电机能顺利休眠进入低功耗模式。
