Dual EV Charger Insulation Monitoring Solution Comparison

A dual EV Charger, also known as a double-gun, dual electric car charger or double-outlet DC fast charger, requires robust insulation monitoring systems to ensure the safety and reliability of charging for two electric vehicles simultaneously. Today, this article will compare the dual EV Charger insulation monitoring solutions from Acrel and Blue Jay.

Now take a dual-gun DC 120kW EV charger as an example to compare the insulation monitoring solutions between Blue Jay and Acrel. In the 120KW DC dual electric car charger, the intelligent switching unit controls the charging module, the DC meter measures the current, the insulation monitor measures the insulation voltage and insulation resistance, and the insulation monitoring is controlled by the controller.

Acrel EV dual charger insulation monitoring solution

Acrel’s DC insulation monitoring solution connects two independent insulation monitors for dual electric car charger insulation monitoring. When the Dual charging pile is used when the charging gun A or B is used alone, the controller issues a command to control the corresponding IMD1 or IMD2 insulation monitor to perform insulation monitoring first. When charging guns A and B are used at the same time, the controller issues a command to control the IMD1 insulation monitor and perform insulation monitoring first. Through the coordinated work of the controller and insulation monitoring device, the safety, stability, and reliability of the DC charging system are ensured.

Blue Jay double EV charger insulation monitoring solution

Blue Jay’s DC insulation monitoring solution only requires one dual-channel insulation monitoring device for Dual EV Charger insulation monitoring. When the double EV charging pile is used, no matter whether the charging gun A or B is used alone, or charging guns A and B are used at the same time, the controller issues the same command to control the dual channel insulation monitor to perform insulation monitoring. However, this dual-channel insulation monitoring device can provide relevant data independently.

Why Choose Blue Jay dual port EV charger insulation monitoring

According to the above introduction, both Acrel insulation monitoring and Blue Jay insulation monitoring can be used for the dual EV Charger. But we recommend Blue Jay insulation monitoring device because of the following advantages:

Cost-save: When you use the Acrel insulation monitoring device (IMD) in Dual EV Chargers, you need two IMDs. However, you only need one insulation monitoring device that can replace the two Acrel IMDs. Thus, you only need to spend one insulation monitoring price so the cost is lower.

Comprehensive insulation monitoring: Blue Jay’s dual-channel insulation monitoring device can monitor two independent high-voltage circuits or conductors at the same time and output independent data to achieve more comprehensive insulation monitoring.

Accurate fault location: By monitoring two channels, Blue Jay’s solution can more accurately locate fault locations, shorten troubleshooting time, and improve maintenance efficiency.

In conclusion, both Acrel and Blue Jay’s dual EV charger insulation monitoring solutions have their pros and cons. You can choose according to your own needs and budget.
