The growing application of lithium-ion batteries brings with it an increased risk of unanticipated energy releases and thermal runaway. Quantifying battery energy release characteristics during product design can help mitigate those risks.
Solar Electronics founder Al Parker used to say about EMI testing, “There’s more than one way to skin a cat.” Here are a couple more.
This article addresses the latest changes to the KS C 9814-1 (and CISPR 14-1) standard.
The state of health of cells in a battery pack under operating condition is difficult to obtain through existing IEC and ISO standard methods under laboratory conditions. However, a cell state of health (SOH) profile shall be able to establish by the comparison of electro-impedance spectroscopy (EIS) generated statically versus dynamic operating data retrieved by battery management system (BMS) communication interface as fragments of EIS.
This article discusses the impact of a shunt inductive discontinuity along the line as well as the effect of feeding two transmission lines in parallel. The analytical results are verified through the HyperLynx simulations and laboratory measurements.
This is Part 2 of an article describing the difference between the electrostatic discharge (ESD) qualification requirements for automotive and standard commercial integrated circuits.
Product safety labels are an important part of keeping users safe and reducing liability risk. There are two main standards for safety labels that are key to creating effective warnings that accurately communicate hazard information: ANSI Z535.4 domestically and ISO 3864-2 internationally.
The Japanese National Institute of Technology and Evaluation has announced that they have confirmed that some of the household electrical heaters available in Japan malfunction when subjected to electrical disturbances.
There are many books and other reference materials available that describe proper printed circuit board (PCB) layer stack-ups to achieve EMC compliance (see References and Further Reading section located at the... Read More...
