The invention discloses a vehicle power supply loop monitoring system and a vehicle power supply loop monitoring method, the vehicle power supply loop monitoring system is suitable for a vehicle power supply and vehicle load equipment and comprises a power monitoring circuit and a control circuit, and the power monitoring circuit is electrically connected with the vehicle power supply and the control circuit. The power monitoring circuit monitors two different load input powers at two different time points, and the control circuit calculates the equivalent impedance of the external power supply loop according to the two different load input powers. And when the equivalent impedance of the external power supply loop is greater than the designed impedance critical value, the control circuit executes a warning program.
本发明公开一种车辆电源供应回路监控系统及车辆电源供应回路监控方法,车辆电源供应回路监控系统适用于车用电源以及车用负载设备且包含功率监测电路及控制电路,功率监测电路电性连接于车用电源以及控制电路。功率监测电路于两个不同时间点监测到两个不同的负载输入功率,而控制电路根据该两个不同的负载输入功率计算出外部电源回路等效阻抗。当外部电源回路等效阻抗大于所设计之阻抗临界值时,控制电路执行警示程序。
