HV Breakout Module 1.1

Single-phase measurement of internal conductor current and voltage

The HV Breakout Module (BM) type 1.1 has been specially designed for safe and precise single-phase measurement in single HV voltage power cables. Inner conductor current and voltage are measured directly and the instantaneous power is calculated in the module.

Highlights

  • Measurement of voltage (U) and internal conductor current (I) in HV applications
    • Voltages up to ±1,000 V (measurement range up to ±2,000 V)
    • Currents up to ±250 A (rated), ±500 A (peak)
    • Calculation of the instantaneous power in the module
  • Simultaneous EtherCAT® and CAN bus communication
  • Output of voltage, current and instantaneous power with up to 1 MHz measurement data rate each

  • Optional calculation of power and RMS values directly in the module and output via CAN
  • In-depth online power analysis with the Vector eMobilityAnalyzer software

Description

The voltage is measured directly. The current is measured via a shunt module which contains differential amplifier as well as temperature sensor and memory for calibration data to perform automatic online temperature compensation.

The HV BM outputs the measurement data including the module-internal temperature values with a maximum data rate of up to 1 MHz via the EtherCAT® interface and simultaneously with a data rate of up to 10 kHz via the additional CAN interface. This enables fast data acquisition via Ethernet with simultaneous data recording via CAN.

The HV BM is inserted into the HV power cables by passing the cables through cable glands into the interior of the module and connecting them there with ring terminals. Alternatively, the cables can simply be installed using customer-specific cable connectors. By measuring directly in the module, rather than over sensor cables, possible interferences are minimized and the precision of the measurement is increased.

Calculation of power and RMS values

With the option Calc. active, apparent and reactive power, power factor as well as the RMS values for current and voltage can be calculated directly in the module from the sampled measured values. Via CAN the calculated values are directly transmitted to the measurement computer or a data logger.

Applications

Typical applications for these HV Breakout Modules are measurements on single or separated HV+ and HV- cables, for example between HV battery and inverter as well as on accessories such as air conditioning compressors, electrical heaters and DC/DC converters.

For the analysis and validation of the high-voltage vehicle electrical system, the HV Breakout Modules are particularly suitable due to their robust design, uncomplicated installation and precise measurement results.

The direct output of power and RMS values allows various analyses without the use of special hardware and software in the road test. More in-depth analyses, such as the investigation of leakage currents and symmetries as well as the correlation with measured values from further CSM measurement modules (e.g. temperatures) can be performed with the Vector CSM E-Mobility Measurement System.
