All you needed was a precise sensor to measure DC current, and after talking to HIOKI you ended up ordering a 10MHz AC/DC current sensor… Does HIOKI employ sales magicians who can sell ice to eskimos? Or does bandwidth simply also matter when measuring DC?When thinking of “bandwidth” in a measurement instrument the first thing that often comes to mind is the bandwidth definition of an oscilloscope. According to the standard for digitizing waveform recorders…
The evolution of battery technology in the last decades has allowed the development of many applications which simply wouldn’t exist otherwise. Of course, one…
Accurately measuring low resistance values To be firmly pushed back into your seat when kicking down the “accelerator pedal” in an electric sports car,…
Regular service and maintenance are required for a safe operation of the battery-powered electric vehicle (BEV). When maintaining or inspecting a BEV, a technician…
The other day I posted an article about how temperature affects a battery measurement because I wanted to find out how much that impact actually was.…
12 V lead-acid batteries can be replaced by 4 x 3 V Li-ion cells. But battery management systems (BMS) are installed in batteries like…
A very popular HIOKI instrument is the BT3554 battery tester. It’s a portable instrument designed primarily for maintenance purposes with voltage ranges up to 60V.Of…
Some time ago I posted an article about how temperature affects battery measurements. What I was curious about at the time was how much impact…
Measuring the impedance of a battery usually leads to a lot of data which then needs to be evaluated afterwards. When using a HIOKI…
Determining the impedance of a battery using the AC-IR method contains certain risks that affects the accuracy of the measurement. A quite significant risk…
