Internal Short Circuit (ISC) Device Helps Improve Lithium-Ion Battery Design

This tool helps manufacturers ensure the safety and reliability of electric vehicle batteries.

Battery safety is key to the acceptance and penetration of electric vehicles into the marketplace. When battery internal shorts occur, they tend to surface without warning, and usually after the cell has been in use for several months. While some failures simply result in the cell getting very hot, in extreme cases, cells go into thermal runaway, igniting the device in which they are installed. The most publicized failures involved burning laptop and cellphone batteries, and resulted in millions of recalls.

Selecting the Right Standard High-Voltage Power Supply

High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. Designed to deliver stable supply voltages at 50 V and up, the power supplies, comprised of sophisticated components and specialized materials, must carefully manage the high voltages and associated effects, for example, corona and arcing. For systems developers choosing standard high-voltage power supplies, the specialized nature of high-voltage power calls for a power supply selection process that reflects the unique characteristics of the high- voltage power supply and its operation.
