Features
Need a solution for use in battery cell inspections or multi-point measurement in an application like semiconductor burn-in testing? Look no further.
Assuring safety when testing cell voltages of a 1500 V battery pack: Achievement unlocked.
Although the voltage of individual cells in a battery may be low at about 4 V, safely measuring the voltage at each cell of an 400 V battery pack, a type that is already being commercialized, requires an instrument with a maximum rated terminal-to-ground voltage of at least 400 V DC.
Since the M7102 has a maximum rated terminal-to-ground voltage of 600 V, it can accommodate testing of 400 V batteries with an ample margin of safety.
Lightning-fast sampling. Fine-grained voltage fluctuation data.
Sampling rate of the M7102
The M7102 can record variations in cell voltage and temperature during charge/discharge testing of vehicle battery packs.
Furthermore, the module provides a 6 V range for lithium-ion batteries and a 2 V range for fuel cells, and measures cell voltage with a high degree of precision thanks to its 18-bit A/D resolution.
