When electronic vehicle systems fail, it’s often not the fault of microcontrollers, memories or integrated circuits. By watching for some of the following problems, designers can often boost reliability of end products, especially in automobiles.
Minimize connections. There’s a high correlation between reliability and the number of electrical connections made at an assembly plant. A dashboard with ten connections, for example, is likely to be more reliable than one with 50 connections.
Make sure wires don’t rub against sharp pieces of metal.
Ensure connections go together with an audible snap. If assemblers hear the snap, they know it’s connected.
Design in reliability at the beginning. Usually, if a car starts out reliable in its first model year, it stays that way.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
