A quick guide to automotive DC-DC converter testing
Sponsored by Chroma Systems Solutions An automotive DC-DC converter receives high voltage from the battery and converts it to a lower voltage to power on board devices such as the instrumentation panel, entertainment system, sensors, LED lighting, and any other on board devices requiring low voltage DC power. Manufacture’s strategies in DC-DC converter development include reduction in size… Read more »
A closer look at how batteries fail
A lot of research has been done to improve lithium-ion battery safety, cycle life and power output over a range of high and low temperatures, yet understanding the fundamental processes and degradation mechanisms in Li-ion batteries remains a challenge. To understand the degradation processes of lithium-ion batteries, it is important to understand how they operate…. Read more »
Berkeley Lab researchers get to the root of the lithium anode problem
In the quest for higher energy density, the use of lithium metal anodes would seem to be a promising approach, if it weren’t for those doggone dendrites. Dendrites are microscopic fibers of lithium, which sprout, tree-like, from the surface of the lithium electrode and spread through the electrolyte until they reach the other electrode, possibly… Read more »
