Hioki Hioki BT4560 Quickstart

BATTERY IMPEDANCE METER

Component measuring instruments

BT4560

Check Li-ion battery reliability in just 10 seconds

Shorten battery cell inspection time

By measuring low frequencies of 1 Hz and below, the BT4560 Battery Impedance Meter
drastically shortens the time required for battery cell internal resistance inspections on
Li-ion battery production lines.

Inspection Time

Battery cell internal resistance inspection time
comparison.

DC-IR measurement (traditional method)

Requires several tens of minutes to around one hour.

AC-IR measurement (using BT4560)

Requires around 10 seconds*

When measuring at frequency of 1 Hz

Fast!

Why it's fast

n No precharging required

Measurement of battery cell internal resistance has traditionally
been carried out by precharging the battery, then passing large
current and measuring its voltage drop (DC-IR). Precharging the
battery usually takes several minutes to several tens of minutes.
The BT4560 uses frequencies of 1 Hz and lower to measure
(AC-IR) internal impedance, thereby eliminating the need for
precharging.

Simultaneous measurement of impedance and voltage

n

Internal impedance and voltage that have been measured
separately can now be measured simultaneously with the
BT4560, enabling drastic reduction of battery cell inspection
time.

Measurement of voltage with a high-accuracy of ±0.0035% rdg.,
and stable measurement of impedance can be achieved simulta­neously with the BT4560.

Correlation between DC-IR and AC-IR Measurement overview

DC-IR measurement AC-IR measurement

Method whereby a DC load is
put through the battery, and the
resistance is calculated from the
voltage variation that occurs.
Because a large current is passed,
a large load is imposed on the
battery.

Response deriving from fast reaction

When the correlation between DC-IR and AC-IR measure­ment values is investigated using multiple Li-ion batteries ...

Method whereby an AC signal is
applied to the battery to measure
its impedance. Because it uses a
relatively small current, it does
not damage the battery.
