The HV Breakout Module 3.1 OBC from CSM provides access to AC mains cables for measuring single-phase to three-phase current, voltage, and power.
EVs need many electrical measurements and so do charging stations. Getting access to AC mains or charging cables isn’t always easy. That’s where the HV Breakout Module 3.1 OBC from CSM can help. Connect the module in line with AC cables and let the box itself make the measurements. With the breakout module, you can safely measure current up to 88 ARMS or ±125 Apeak single-phase up to three-phase circuits. It can measure star voltages V1, V2, and V3 against neutral. The breakout box has four configurable measurement ranges.
The breakout box can mount inside an EV.
Need to calculate power from voltage and current measurements? With option Calc, the HV Breakout Module 3.1 OBC can calculate RMS values for voltage and current, active power, apparent power, reactive power, and power factor.
Because the breakout box has Ethernet and CAN bus ports, it can provide measurements directly to a computer. The HV BM 3.1 OBC outputs voltage and current measurement data with a maximum data rate of 2 MHz over the the XCP-on-Ethernet interface and simultaneously with a data rate of up to 5 kHz over the CAN bus.
You can mount the breakout box in a vehicle to measure the voltage and current from a charging station or you can install it in a portable case for testing charging stations.
