Realizing a Compact, High-precision PV Inverter Testing System
For PV inverter production lines

Introducing a modular power meter that’s ideal for PV inverter production line use

Among PV inverters, string inverters are being engineered to operate at higher voltages and to provide more input circuits in order to facilitate energy-efficient operation. Equipment used on lines producing such inverters must support high voltages while providing sufficient expandability to accommodate a growing number of measurement points, all in a smaller testing equipment footprint. Hioki developed the M7103 to satisfy these requirements.

Unmatched Capability for Capturing Data from High-Voltage Battery Packs
Suitable for Battery Charge/Discharge Testing

Product Concept

Battery packs consist of many battery cells that are connected in series. Since variability in cell characteristics can lead to a decline in the battery pack’s overall performance, it’s critical to ascertain voltage and temperature behavior at the cell level.
Furthermore, it’s necessary to make a comprehensive evaluation of the battery pack’s overall characteristics during charge/discharge testing. This can be done by measuring individual cells’ voltage and temperature at the same time as total voltage and total current.

Manufacturers are designing batteries of increasingly high voltage for use in electric vehicles (EVs). 
As battery voltages rise from 400 V to 800 V, it becomes harder to measure battery cells’ voltage and temperature safely. Instruments used to conduct charge/discharge testing of these high-voltage battery packs must now have higher terminal-to-ground and module-to-module voltage then before.

Modules that are ideal for use in measuring the voltage of stack cells in battery packs and in charge/discharge testing on cell production lines

Choose and combine the suitable module for your application.
For measuring the system's total voltage and total current, select the Power Measurement Module M7103.

*1: Data output based on UDP

Measurement data are output for every sampling in real time. The fastest speed is achieved with intervals of 5 ms.
This is useful when realtime processing is required, such as HIL.

*2: Multiple loggers synchronized for measurement

Synchronized measurement is enabled with an optional Optical Connection Cable L6101 (1 m) or Optical Connection Cable L6102 (10 m).
The measurement data from all of the synchronized instruments can be output from LAN2 of the primary instrument.

*3: Data output via CAN

The measured value can be output via a Controller Area Network (CAN).
The value can be used for data integration with the information of an in-vehicle device, such as the battery management system (BMS).
