According to the charging line temperature monitoring method, the power adjusting method based on the temperature difference and the vehicle, when the vehicle starts to be charged, the initial temperature of the charging line is determined, and the initial temperature serves as the reference point of temperature change and is used for measuring the temperature change; in the vehicle charging process, the current loss voltage between the vehicle and the charging pile is monitored in real time, the current temperature of the charging line is determined according to the current loss voltage, and due to the fact that the temperature changes in real time in the charging process, power adjustment can be conducted in time by monitoring the loss voltage in real time; the current temperature of the charging line is calculated through the loss voltage, and the obtained current temperature is relatively accurate through temperature monitoring based on the physical principle; and then the temperature difference between the current temperature and the initial temperature is sent to the vehicle, power adjustment is performed according to the temperature difference so as to reduce the temperature of the charging line and reduce energy loss, and the burden of the vehicle can be reduced and the use cost can be reduced when the method is applied to the cloud platform.

    本申请提供的充电线温度监测方法、基于温差的功率调节方法及车辆,在车辆开始充电时,确定充电线的初始温度,该初始温度作为温度变化的基准点,用来衡量温度的变化;在车辆充电过程中,实时监测车辆与充电桩之间的当前损失电压,根据当前损失电压确定充电线的当前温度,由于在充电过程中温度是实时变化的,实时进行损失电压的监测可以及时的进行功率调节,通过损失电压来计算充电线的当前温度是从物理原理进行出发的温度监测,得到的当前温度比较准确;然后将当前温度和初始温度间的温差发送至车辆,并根据温差进行功率调节,以降低充电线的温度,降低能量损耗,且在云端平台进行应用可以降低车辆的负担,还可以降低使用成本。
