Measure battery module’s voltage and
internal impedance
Hioki BT3554, Fluke BT521 or meters
with the same or better voltage and
resistance measurement resolution and
accuracy is recommended.
- Voltage resolution: 1mV
- Voltage accuracy: ±0.1% of reading
- Resistance resolution: 0.001mΩ
- Resistance accuracy: ±1% of reading
Battery tester may be used to measure
the contact resistance between bus bar
and the joining terminal if a dedicated
resistance meter is unavailable.
Measure the contact resistance
between bus bar and the joining
terminal
(Hioki RM3548 or meters with the
same or better resistance
measurement accuracy is
recommended)
