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 of the first things that comes to mind are electric cars. But what about battery powered vacuum cleaners (that are not just noisy but which actually clean)? Or new products like vapes, smart watches or e-bikes? They all require powerful yet lightweight batteries – and these batteries need to be developed,…

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…
