Introducing a Modular Data Logger
Engineered for Use in Embedded Applications

NEW

Measurement systems are being called upon to deliver sophisticated capabilities as efficient energy use and e-mobility technologies progress.
Hioki data loggers drive solutions that turn measurement system issues into advantages, for example by assuring the safety of high-voltage systems, accommodating enormous numbers of measurement channels, and realizing data compatibility with upstream systems.

Key Features

  • Add measurement modules as needed to create the measurement system you need
  • [LR8102] Add channels by synchronizing sampling across multiple loggers
  • [LR8102] Transfer high-speed data in real time

Ideal Data Loggers for Battery Charge/Discharge Testing

Batteries used in electric vehicles are becoming increasingly high-voltage. To safely measure battery cell voltages and temperatures during charge/discharge testing of high-voltage battery packs, the terminal-to-ground voltage and module-to-module voltage of the instrument are critical.

Hioki's data loggers, LR8101 and LR8102, provide solutions that turn measurement system challenges into advantages. These solutions ensure safety in high-voltage systems, support a large number of measurement channels, and link data with host systems.

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.
