Measure Internal Impedance on Batteries using a Hioki 3554
Вставка
- Опубліковано 11 тра 2015
- How to determine failure levels for your batteries, the internal resistance measurement level, and cut-off voltage. Also gives a quick overview on setting up the Hioki 3554 Battery HiTester to conduct tests.
Takes on-the-spot measurements of the internal resistance, voltage and temperature of lead-acid batteries, principally for UPS and similar applications, without needing to shut off the battery. Instantaneous results, on a three-rank scale of Pass, Warning, or Fail, using a composite decision based on the internal resistance and the voltage. Resolution of 1 µohm, necessary for high capacity batteries (of at least 500 Ah). Includes Hioki 9460 clip type temperature leads.

Cheers mate, nice overview on how to properly test batteries, for some reason the whole Internet is full of hobbyists checking their car batteries, this is the first video that show battery testing in a professional setting. :)
Cheers Graeme, nice overview. Just bought one of these to make my UPS bat monitoring easier. Certainly a fast meter and fairly straight forwards to set up. The only issue i have now is all our critical testing is done out of hours in overtime so I need to slow it down :-)
SO HELPFUL THANK U VERY MUCH SIR YOU ARE THE BEST
Thanks alot about clip, pls show me how to connect and download data from Laptop.
Does the ciruit need to be open or can test on connected batteries also.
does the unit automatically compensate for voltages differences
hello sir,
please let me know the 12v,18AH battery normally has internal resistance?
Can you tell me if you can test batteries in series, testing two batteries at the same time as I am having trouble accessing the battery terminals.
If you measured two batteries at the same time you would have the addition of the two impedance measurements. So it would be a reasonable indicator if something was marginal or not.
can we test the battery internal impedance while the battery is still connected with UPS and charging?
I have not used these in the field however according to the documentation I have the main selling feature of this type of battery testing is that you do not need to take the batteries offline to test them.
what is the relation between impedance and battery voltage?
Each different battery chemistry and battery voltage will have a different relationship. So you have to get the manufacturers documentation to determine what is acceptable and unacceptable impedance measurements. You can take a number of 'good' similar batteries and experimentally determine a 'good' reading. Its a bit of an empirical measurement really. If you only have one battery to test then you have to rely on the manufacturers specification.
I have a Hioki battery tester BT 3554.
After measuring a battery I get resist 0.02 mOhm ( before was 3-5 mohm). I replaced battery but i still have same measurement by hioki
Please can you advice me what can be wrong
Setting on hioki tester is same like before
what is the difference between battery impedance and resistance??
Impedance resists the flow of current in an AC circuit. In AC, it has to account for resistance and reactance. Resistance prevents the flow of current flow in a DC circuit, but DC is real power so no need to account for reactance.
Batteries internal impedance also changes depending on frequency of AC signal. Thats probably why the standard internal impedance measurement is an AC signal at a set 1kHz and outputs a millions measurement (ex: 11 mΩ).
Low impedance is for handling changes in load when accelerating in a car. Low internal resistance is important for efficiently delivering power to the motor in a car.
Hello, does this tester measure the Internal Resistance of the lead acid battery even when the UPS (equipment) is online?
Yes you can be online... great for quickly testing battery banks. Alternatively if you need to stress test the batteries you might use something like the Megger Torkel 950 which actually does a load test and discharges the battery, this has to be done offline.
Graeme Murphy Thank you for this!
How can I get same (kind) of result with the tool I have : Extech 380462: Precision Milliohm Meter (220VAC)
I get sparkling ang no stable reading
Probably because its measuring resistance NOT impedance. This instrument measures the impedance using a low voltage AC source...
@@GraemeMurphy54 this makes no sense
@@randycollens2681 Resistance is DC and Impedence is AC. Slightly illogically you measure an AC parameter across a DC device in this case a DC battery. It just happens to give you a reliable and repeatable measure of the health of the battery.
Sir,we lerned in university that resistance is measured in DC circuit and impedance measured in AC circuit ,
The battery is DC device and then why we called impedance rather then resistence
Because the device measure AC impedance of the battery. The fact that the battery is a DC device is irrelevant here. It is a case of 'it just so happens', that the AC impedance indicates the health of a battery.
@@GraemeMurphy54 hey nice video , i have a question i know that we can check a battery health by measuring the cell voltage cann't we use that instead of measuring the impedance .
@@mohbit3336 no, ocv can tell you state of charge not state of health
why you use 22mohm for setting 'pass' - currently the internal resistance was 11mohm. give your email for detail discussion.
See the user manual part....there written about that
It says it can give 2 times the value...
Was it ACIR measurement or DCIR
It tests using a 1KHz(+/- 80Hz) signal at 160mA or 16mA depending upon the range.
What is the Price Of this Meter?
We rent them. If you check the Hioki web site you should be able to find your nearest distributor
So the older the battery gets the more the internal resistance will be?
Yes... but by how much depends on the technology of the batteries... You need to either get the info from the battery manufacturer OR have a number of examples and develop experience yourself.
Impedance is for AC circuits. You’re measuring DC batteries, therefore are testing internal resistance, not impedance!
