The invention provides a power regulation method and device, a vehicle-mounted charger and a vehicle, when a charging line is connected with the vehicle-mounted charger, an initial output voltage sent by a cloud platform and an initial input voltage sent by a battery management system are received, and an initial temperature of the charging line is determined according to the initial output voltage and the initial input voltage; the initial temperature is a reference point of temperature change and is used for measuring the temperature change; in the charging process, the current output voltage and the current input voltage are received in real time, the current temperature of the charging line is determined according to the current output voltage and the current input voltage, and power adjusting information is sent to the battery management system according to the temperature difference value between the current temperature and the initial temperature; the temperature of the charging wire is reduced by reducing the output power of the charging pile, so that the energy loss caused by the charging wire is reduced.

    本申请提供一种功率调节方法、装置、车载充电器及车辆,在充电线与车载充电器连接时,接收云端平台发送的初始输出电压和电池管理系统发送的初始输入电压,并根据初始输出电压和初始输入电压确定充电线的初始温度,该初始温度是温度变化的基准点,用来衡量温度的变化;而在充电过程中,实时接收当前输出电压和当前输入电压,并根据当前输出电压和当前输入电压确定充电线的当前温度,根据当前温度和初始温度的温度差值向电池管理系统发送功率调节信息,通过降低充电桩的输出功率来降低充电线的温度,进而减少充电线造成的能量损耗。
