Hioki M7100 – Voltage and Temperature Module (Up to 15 channels)

• The M7100 cannot perform measurement by itself; separately sold Data Logger LR8101 or LR8102 is required
• Highly insulated module featuring high-speed sampling
• Safely conduct charge/discharge testing of increasingly high-voltage batteries
• For 600 V to 1500 V battery packs
• 15ch, voltage and temperature (thermocouple) measurement

Modules are required to connect the data logger to the device under test. The loggers can be combined with measurement modules to easily expand the number of input channels to a maximum of 300 channels for the LR8101 and 3,000 channels for the LR8202. Modules are sold separately.

• The M7100 can measure voltage and temperature across 15 channels at a sampling rate of 10 ms.
• If no more than 8 channels are used, it can make measurements at a sampling rate of up to 5 ms.
• Up to 10 measurement modules can be connected to a single data logger, allowing the number of channels to be increased to 150 channels.
• A JIS and EIA-standard 19-inch rack can accommodate one logger and 6 measurement modules for a total of 90 channels per shelf.
• Furthermore, if up to 10 of the LR8102 advanced models are connected with optical cabling, their sampling can be synchronized, allowing the number of measurement channels to be increased to a maximum of 1500 channels.
• Easy expandability ensures you’ll be ready when you wish to evaluate future high-voltage systems that have even more battery cells.

• Although the voltage of individual cells of a battery may be low at about 4 V, safely measuring the voltage at each cell of an 800 V battery pack, a type that is already being commercialized, requires an instrument with a maximum rated terminal-to-ground voltage of at least 800 V DC.
• Since the M7100 has a maximum rated terminal-to-ground voltage of 1500 V DC (CAT II), it can accommodate testing of 800 V batteries with an ample margin of safety.
• It can also be used to measure cell voltage and temperature of next-generation battery packs that exceed 800 V and power storage systems such as energy storage systems (ESSs) that exceed 1000 V.

• Data transfers at an interval as short as 5 ms mean you can output data for all cells to an HIL system in real time (when using only the LR8102)
• The logger can continuously transfer data at high speed to an upstream system using UDP communication (LR8102 only).
• Modules sample data at high speed at a rate of up to 5 ms (1 to 8 measurement channels, voltage only) and output it immediately.
• Since the data logger continuously acquires live voltage data for measured cells at an interval as short as 5 ms, data can be used in real-time simulation by an HIL system.
• In addition, this capability allows comprehensive analysis of charge/discharge characteristics by increasing the simultaneity of total voltage as monitored by the charge/discharge system and individual cells’ voltage data.
