Hioki Launches Battery Impedance Meter BT4560

Instrument offers New Approach to Lithium-ion Battery Evaluation

The lithium-ion battery market continues to grow rapidly, and products must deliver performance and quality that meet the highest standards. The time-consuming nature of the conventional approach to evaluating lithium-ion batteries, which requires measurements that can take as long as one hour, has given impetus to manufacturers'' efforts to improve measurement efficiency. The newly launched BT4560 offers a new measurement approach that delivers roughly the same ability to evaluate battery performance and quality as the conventional approach but with measurement times of approximately 10 seconds, dramatically improving measurement efficiency.

Principle Application: Evaluation testing of lithium-ion batteries used in automobiles

Key Features:

1. Faster measurement and increased measurement efficiency through low-frequency AC-IR measurement

The BT4560''s low-frequency AC-IR measurement function dramatically accelerates the process of evaluating lithium-ion batteries, improving measurement efficiency.

2. Low-frequency AC-IR measurement at a reasonable price

Until now, performing low-frequency AC-IR measurement at a high level of precision has required an expensive measurement system with a high price tag. The BT4560 enables low-frequency AC-IR measurement at a more affordable price.

3. High-precision, stable measurement

The accuracy and maximum resolution for super-low-impedance measurement and high-accuracy DC voltage measurement are shown below:

Super-low-impedance measurement

Accuracy: 0.4% rdg. 8 dgt.*

Maximum resolution: 0.1 mΩ

*When performing pure resistance measurement at SLOW speed.

High-accuracy DC voltage measurement

Accuracy: 0.0035% rdg. 5 dgt.

Maximum resolution: 10 mV

In addition, the BT4560 features a circuit architecture that is resistant to the effects of contact resistance when measurement probes make contact with the battery and of measurement probes'' wiring resistance, delivering stable measurement. In this way, the instrument allows cabling on production lines to be routed with a higher degree of freedom than was possible with legacy models. Furthermore, Hioki offers two specially designed probes (clip-type and pin-type) for users to choose based on their applications.
