An electric vehicle charging system is provided. In some embodiments, an electric vehicle charging system may include an electric vehicle including a direct current to direct current (DC-DC) booster that boosts a first voltage to a second voltage of a battery of the electric vehicle, and a first insulation monitoring device (IMD) that includes an active symmetry circuit. In various embodiments, the electric vehicle charging system may further include an electric vehicle power supply device including a second IMD and an output voltage including a first voltage, where the first IMD is communicatively coupled with the second IMD, and where the first IMD is communicatively coupled with the second IMD. The first IMD adjusts a third voltage on the negative side of the insulation resistance of the electric vehicle to a fourth voltage on the negative side of the insulation resistance of the electric vehicle power supply equipment.
提供了一种电动车辆充电系统。在一些实施例中,电动车辆充电系统可以包括电动车辆,其包括将第一电压升压到电动车辆的电池的第二电压的直流到直流(DC‑DC)升压器,以及包括主动对称电路的第一绝缘监测设备(IMD)。在各个实施例中,电动车辆充电系统还可以包括:包括第二IMD和包括第一电压的输出电压的电动车辆供电设备,其中,第一IMD与第二IMD通信耦合,并且其中,第一IMD将电动车辆的绝缘电阻的负侧上的第三电压调整为电动车辆供电设备的绝缘电阻的负侧上的第四电压。
