Design

When Gaston Planté invented the rechargeable battery in 1859, a new system of stored energy emerged. Today, digital technology has helped to make the electrochemical battery smart by providing a window into a battery’s state-of-function.

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.

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.

Implementing a process of EMC compliance for a specific project is much more than simply ensuring that the design engineers follow a long list of “do’s and don’ts” in the form of EMC design rules. Following this process will reap benefits when EMC performance is evaluated at the end of the design process.

A careful review of empirical research, multiple ESD standards, and return on investment provides a strong case for evaluating the installation of ESD flooring in server rooms and data centers.

Part 1 of this two-part article explores some basic rules for terminating cable shields. Part 2 of the article will appear in our October 2022 issue and will summarize the results of recent testing conducted by the author on the shielding effectiveness of screened cables up to 2.8 GHz
