Freescale introduces intelligent sensor for car battery monitoring Freescale Semiconductor today introduced the MM912J637 intelligent battery sensor (IBS), which accurately measures the voltage, current and temperature of lead-acid batteries and calculates the battery state, all while operating in harsh automotive conditions. The ability to accurately assess these battery parameters is becoming more important with increases in the number of hybrid vehicles on the road and overall electronic content in vehicles, as well as the introduction of start-stop systems... “With the rise in electrical content in hybrid and electric vehicles and the advent of the start-stop systems, it’s crucial to be able to accurately monitor a vehicle’s battery at all times, especially under tough automotive conditions,” said Gavin Woods, vice president and general manager of Freescale’s Analog, Mixed-Signal & Power Division. “We are providing the industry’s first fully automotive qualified and cost-effective solution that helps to ensure precise monitoring of important battery parameters which can be shared with other vehicle systems and the driver, providing the driver a certain amount of peace of mind when it comes to knowing the battery’s status.” Complete article. From this picture over at CleanMPG.com, it looks like the unit fits on one of the Optima "yellow tops." But is there a model for the OEM Optima replacement, and better yet the OEM battery itself? The biggest unanswered question is, WHERE CAN I GET ONE? Strangely, when I do a Google search for images on this, one of the pictures is: I hope this isn't just a pipe dream.
This looks interesting, I would to have one of the evaluation chips to play with! Here is a link to the data sheet! http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MM912J637&fsrch=1&sr=1
