The Battery Impedance Meter BT4560 offers reliable EIS measurement of high-capacity EV batteries.
The battery industry is at a critical turning point, choosing between adopting new measurement methods to accommodate the evolving design of large lithium-ion batteries or pushing conventional techniques to their limits.
Hioki, a test and measurement equipment manufacturer, is addressing this challenge with two solutions: the BT4560 for EIS measurements and the BT6075, which maximizes the potential of traditional methods.
The Battery Impedance Meter BT4560 is capable of measuring the internal resistance of various types of batteries over a wide frequency range. Measuring lithium-ion batteries at multiple frequencies (EIS) offers key advantages. For instance, internal resistance at 0.01 Hz closely reflects the actual operating state of battery cells. In contrast, in high-capacity cells, 100 Hz can be more accurate than the traditional 1 kHz by reducing the influence of inductance.
Multiple frequencies provide the flexibility needed to adapt to evolving battery designs. The lower limit of the measurement frequency has been expanded in the newest model of the BT4560-50, now ranging from 0.1 to 0.01 Hz.
- Measurement frequency: 0.01 Hz to 1.05 kHz
- Maximum input voltage: 5 V
- Resistance measurement range: 3 mΩ, 10 mΩ, 100 mΩ
- Minimum resolution: 0.1 μΩ (3 mΩ range, 10 mΩ range)
The Battery Tester BT6075 enables high-precision, high-speed, and stable internal resistance measurement of batteries at a measurement frequency of 1 kHz. It represents one of the highest-quality and top-class models of traditional battery testers.
The Battery Test BT6075 offers precision OCV/IR testing for high-capacity batteries.
Hioki has pursued the limit of performance for users seeking further advancement in internal resistance measurement using the conventional method with this tester.
- Measurement frequency: 1 kHz
- Maximum input voltage: 100 V
- Resistance measurement range: 3 mΩ, 30 mΩ, 300 mΩ, 3 Ω, 30 Ω
- Resolution: 0.01 μΩ (3 mΩ range)
Hioki remains committed to supporting the development of next-generation batteries and advancing a sustainable, circular battery economy.
