SHANGHAI, CHINA, Wednesday evening, Nov. 16, 2011—Have you ever had to bite your tongue while some Silicon Valley engineer droned on about her latest product development project—how it’s the most sophisticated and robust piece of E/E work the world has ever seen, and how it’s just light-years more advanced than anything the wheezy old auto industry can muster?

Well, it’s nice, sometimes, to toss some numbers right back at ‘em, to prove that auto has its mojo workin’ now more than ever. At this week’s 2011 SAE Vehicle Batteries Summit here in electronics-savvy Shanghai, Texas Instruments’ Systems Engineering Manager Bob Shoemaker tossed the audience a "Laptop vs. EV" battery comparison (see caption) that shows how tough the automotive engineer's job really is.

Bob was just making a subtle point, of course, but the audience of automotive battery engineers, researchers, chemical engineers, and power-grid experts appreciated it. The thermal operation delta always gets a few chuckles in this comparison. Does room temperature even exist in automotive product development?
