According to the power regulation method and device based on the temperature of the charging line and the battery management system, the output voltage sent by the charging pile is received in real time, the input voltage is collected in real time, due to the fact that the temperature changes in real time in the charging process, power regulation can be carried out in time by monitoring the output voltage and the input voltage in real time, and the charging efficiency is improved. The current temperature and the initial temperature of the charging line are determined according to the output voltage and the input voltage, the initial temperature is a reference point of temperature change and is used for measuring the temperature change, and the current temperature is the temperature of the charging line at the current moment; the initial temperature and the current temperature of the charging line are calculated through the output voltage and the input voltage, the obtained initial temperature and the obtained current temperature are relatively accurate, finally, the temperature difference between the current temperature and the initial temperature is calculated, and the charging power is adjusted according to the temperature difference. 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.
